Best practices for developing a green website

Digital Marketing, ,

The ecological impact of IT services is now known. By becoming aware of the environmental consequences of IT tools, digital ecology takes on its full meaning. When developing a website, an application, or any other IT service, we have seen that eco-design needs to be taken into account as early as possible in the project. Today, let’s talk about the best practices to follow to develop an ecological website.

Objective: reduce the resources used by the site

The goal is simple: you have to reduce energy consumption, thus reducing the number of devices and the cumulative power required to run the Web application. In other words :

  • Reduce the number of requests,
  • Reduce the volume of data exchanged,
  • Limit processing, especially on the server-side.

Use a repository of good practices for digital ecology

Before getting to the heart of the matter, know that there is a repository of rules published by CNumR ( Collectif Conception Numérique Responsable ). Note that the rules below do not come from this repository but come from my design and development experience. I, therefore, invite you to complete them by purchasing Ecoconception web: the 115 best practices.

Use browser caches

The first step towards a less consuming site: use cache. Or rather caches! In 2014, I explained to you that there are many caching mechanisms to optimize your site’s performance. This point is crucial: a modern website weighs several MB or even ten MB for the most greedy. By using the caches available to us, we avoid the transfer of many files during navigation.

It would help if you played on the following cache levels:

  • the browser cache consists of using the storage of files on the client’s web browser via the HTTP Cache-Control and Expires headers. It is managed by the browser itself and avoids the systematic loading of static resources: CSS, JS, images, etc.
  • The browser storage of using space provided by the browser allows you to store data (or SessionStorage LocalStorage). For example, rather than loading drop-down list X times, load it once and store it on the client-side; you will avoid requests on the server.

Use application caches

In line with the previous good practice, it is imperative to set up caches on the server-side. Thus, many unnecessary processing operations are avoided: calls to the database, data calculations, generation of pages, management of referential data, etc.

It would help if you played on the following cache levels:

  • the OPCode cache (OPcache) now embedded natively since PHP 5.5,
  • the application caches of your architecture: database cache ( Mysql Query Cache, for example), application data caches ( APCu, Redis, Memcached, etc.).

Use server caches

Last level of cache: the storage of pages on the Web server-side. Modern servers allow static pages to be stored without calling on the backend, which generates the HTML page: Varnish, Nginx, Apache offer to cache static pages to avoid their systematic generation ( Apache mod_cache or Nginx proxy_cache ).

You can also use ESI (Edge Side Includes) or SSI (Server Side Includes) to cache chunks of pages while dynamic elements are loaded asynchronously. The most common example is a “shopping cart” component on an e-commerce website that is necessarily dynamic while the rest of the page is static (product page, category, etc.).

Limit the number of requests

The right request is the one that doesn’t go away. Caches help reduce them when browsing, but the initial loading of pages is no exception to this rule. Must, therefore :

  • Concatenate and minify your assets (JS and CSS),
  • Depending on the case, completely delete your JS and CSS files and directly include the JS and CSS code as an inline in the HTML code (with GZIP compression active),
  • Use sprites for your icons. The best is to use icon fonts including only the icons used),

Enable GZIP compression

Another good practice to reduce the bandwidth required to load your site: enable GZIP compression on your Web server. In Apache, this is the mod_deflate module. Under Nginx, look at the side of the ngx_http_gzip module.

Resize and compress images

Images are very bandwidth-consuming resources. You may apply the techniques outlined above and end up with an initial HTML page at 20Kb; if you then load several mega images, your work will be useless. So be sure to:

  • Resize your images according to the use made of them. 1600 × 900 images used as a 250 × 100 logo are unnecessary: ​​resize the image correctly. Especially since we also reduce the browser’s processing, which will no longer have to force the resizing on display.
  • Compress your images. On JPEG, you can easily go down to quality between 80 and 90% without a big loss. On PNG, be sure to use a lossless compression tool (TinyPNG, for example).

Load the images in lazy-loading

The lazy-loading images are a technique to load images only when you need it, i.e., you scrolled above your page. Thus, the images not displayed on your browser are not loaded at the initialization of the page, but only when they become visible (in fact, a little before).

This technique, which is easy to implement, is interesting on all access devices, but particularly on smartphones, for two reasons:

  • the bandwidth in 3G or 4G is lower: your site will therefore load faster if the invisible images are not loaded,
  • the surface of the site displayed is smaller on a smartphone (the viewport which designates the visible surface in your browser): so potentially you will have to load less image)

Use responsive images

The configuration of responsive images allows browsers to choose which images to load according to different criteria: screen size, pixel density (for HD or 4K screens, for example), the actual surface used by the image when it is displayed. This technique adjusts the loaded images, and therefore the amount of data transferred, as needed: you do not need an image of several MB on mobile, for example.

Avoid image sliders

We often tend to put an image slider at the start of the site to give a dynamic dimension. Ecologically speaking, this is a mistake (and ergonomically as well, by the way, as users rarely see images other than the first).

Delete videos

Exit the videos automatically played at the initialization of the page or the animated page backgrounds. Video streams represent almost 60% of global Internet traffic. Netflix alone is 15%… In many situations, videos have no interest other than seeing something moving on the screen. Delete them and, if they are really useful, turn off the autoplay.

Avoid full page reloads

Have you set up an automatic reload of your page every 60 seconds? On the one hand, it is unbearable for users … On the other hand, it is needlessly consuming resources. When necessary, favor AJAX requests that only load what is useful or WebSockets if you need real-time. On this last solution, I’m looking for information about resource consumption, contact me if you have any!

Be sober on scheduled tasks: AJAX, CRON …

Whether for AJAX requests or CRONs, there is no point in planning a data refresh every 10 seconds if the information only updates twice a day. Maybe 30 minutes is enough. All recurring scheduled tasks must be carefully dimensioned to avoid unnecessarily excessive consumption.

Avoid storing unnecessary data

Computer servers host an incalculable amount of unnecessary data (think of your mailbox). Databases: it’s the same. We generally collect much more data than necessary for the proper functioning of the application. Be reasoned about the data collected, particularly on the logs and application traces that are constantly growing. Not only will the planet thank you, but you will also take a step towards GDPR compliance (which involves justifying the use of users’ data).

Conclusion

You will have understood: the line of conduct to adopt when developing an eco-responsible website or application is to limit the transfer of resources between the client and the server.

How to properly reference your blog?

Digital Marketing, , ,

For several years now, natural referencing has become the workhorse of many companies who want to increase their visibility on the web and stand out from the competition. Because yes, getting your blog well-referenced for search engines is an essential step in attracting visitors and generating prospects.

Through blogging, SEO is at the core of the Inbound Marketing strategy and needs a certain investment and a great deal of involvement. But this medium and long-term strategy will undoubtedly allow you to acquire new prospects in the long term. Remember that a professional blog can generate 73% more leads than a business that does not.

Here are some practical tips to properly rank your blog and gain visibility on the web.

Choose the right keywords to rank your blog

The good SEO of a blog starts with a choice of relevant keywords on which you want to go back. Oh yes! To get results, you already need to set clear and specific goals. Do you have anything to say? One page = one keyword. Don’t go all over the place and structure your ideas.

A blog is no different from a website page. To optimize the SEO of a blog, each page, in other words, each article, should focus on the keyword you want to come up with.

But what is a keyword?

In reality, it is more about key phrases than keywords. These are the expressions used by Internet users in search engines to find something (a product, an answer, a help, etc.).

In the screenshot above, the key phrase is “start a free blog”. We are therefore looking to get back to this keyword by creating content optimized for search engines. For this, it is necessary to build your blog article by integrating the chosen keyword as follows:

  • in the title of the page (It is the title h1 which is displayed by the search engines. You must therefore place the keyword there)
  • in the URL of the page (This is called the permalink in WordPress. Use a link that contains the keyword rather than an article number)
  • Three times in the page’s text (Try to place your keyword harmoniously throughout your article).
  • if possible in the alt  tag  of the image that accompanies the page (It is a tag that describes the image in case of not display)
  • once in bold in the text of the page

Remember to add your keyword in the metadata of your article (the meta description in particular).

Choose the right keyword

Referencing your blog well on a keyword is good. But you still have to choose the right keyword. Indeed, if you optimize your article on a request carried out only ten times a month, your results will be very limited. Unless you are in a niche sector …

To help you choose your key phrases, you can use tools like Google Trends, which allows you to see the evolution of searches made on the search engine.

Other tools allow you to analyze different keywords and suggest the most relevant to you to optimize the SEO of your blog. The app analyzes your blog in real-time to enhance your pages and improve their SEO, in addition to helping you find the right word.

Create a mesh of internal links

Optimizing the SEO of your blog also goes through a linking strategy. It is extremely to create a mesh of internal links between the various articles of your blog. Indeed, the robots that analyze your content seek to determine if your content is relevant to the Internet user. They do this by making sure your article references similar topics that could prove your expertise in the field. Links, hypertext links, or even hyperlinks allow two pages to be linked together. All this will allow you to create an internal link between all the pages of your blog. To do this, follow the instructions below:

  • Insert links in every page of your blog on the appropriate keywords.
  • With each new concept discussed on a page, you can insert a link to another page that deals with the subject.
  • Add links at the bottom of the page to other interesting pages to read.
  • Always have a link to your blog’s home page regardless of the page the user is on.

External links are often forgotten but essential!

This is called the net linking strategy, and it is essential to keep your blog alive. These are the links that you point to other web pages and links that you can acquire on other websites and redirect to your blog. The main interest of this kind of link is to give notoriety to your blog. The more popular the page with a link to your blog, the more notoriety your blog will gain. To get this kind of link, you need:

  • Share your blog’s content on social networks: the existing community of the various networks (Facebook, Twitter, Google Plus, LinkedIn, etc.) will share your content, thus creating external links to your site.
  • Leave relevant comments on the blogs of your activity: by doing this, you will make yourself see players in your ecosystem who will then be able to take a look at your blog, and if the content is of quality, they will not hesitate to share your content
  • Write articles on a partner blog that will give you an external link to your blog.

There are other ways to rank your blog. The 3 points presented here are linked to natural referencing, accessible to anyone with time to spare. It certainly takes time, but it is nonetheless very effective!

Best Tips to learn the code for beginners

Digital Marketing, , ,

Coding has exploded in recent years, moving from something used in computer games and the occasional electronic device to something that fundamentally defines how we live in the modern world. Almost all modern devices, electronics, and machines contain at least some code. If more individuals are interested in choosing to code for the open-source community, the number of tech job listings will also continue to grow. This means that now is the time to learn to code for beginners.

We’ll start by defining what coding is and why you should learn it. After that, we will move on to a step by step guide to code dummies. We’re going to look at some of the most common coding languages like C/C++, PHP, and Python. We’re also going to look at some online coding courses that will help you learn these languages.

What is computer coding?

To begin with, we need to define exactly what coding is. Most programmers would agree that coding is: “The act of writing code which is compiled to form programs, which can be executed by a computer or a code reader, and which has a specific function or set of functions.”

Now, this definition is quite broad. In reality, what we mean by encoding will depend on the type of encoding we are referring to. An example of a web developer is someone who writes code used to build sensitive and usable websites. Overall, coding helps a business or organization design the best website possible. You will read more about coding in our previous post, “How To Program.”

However, someone working in navigation and aerospace engineering might have to write code that allows an aircraft to operate on autopilot during long trips. While this is completely different from building a website, it is still coding.

So before you start looking for the answers to the “How to Code for Beginners” section, you should think carefully about what type of coding you want to use. It will dictate which languages ​​you choose to learn and how you learn them – but more on that later. For now, let’s see how to start learning to code for beginners.

Why should I learn to code?

As we noted above, coding is an exciting new field that offers a world of opportunities for people keen to learn. Despite what you’ve heard, learning to code isn’t that hard, especially when you compare it to the skills needed to get the most skilled jobs.

An average person can learn the basics of code for beginners quickly enough to write their simple programs in weeks. A few months of hard work will allow you to master at least one programming language. Working hard on learning how to code for dummies for more than a few months should give you all the skills you need to become a career coder.

There are numerous explanations why you should learn to code, including:

It’s fun coding! Imagine that you have the skills to develop your websites, create responsive mobile games and program packages for data analysis. If you learn to code, you will be able to do all of this and more in a fun and engaging way!

Coding will give you valuable skills. Learning to Program for Dummies will give you enough skills and experience to pursue a career as a coder or programmer.

Learning to code will ensure job security. Likewise, being able to pursue a career as a coder will provide you with significant job security. Coders and programmers are in demand in the modern world, which creates many jobs in the field.

As you can see, there are many reasons why you should start learning how to code for beginners. Therefore, the following step-by-step guide was created. Dig and have fun! – Dig and have fun!

Guide to coding for Dummies

While coding is relatively easy to learn than many other technical skills, there is still something that scares people. At first glance, it may seem difficult, confusing, and very difficult to master. I mean, how are you going to learn to code a website if you have no programming experience?

The answer is simple: follow our guide to beginner code learning step by step! It will help you to know what measures to be a programmer and what initiatives to speed up your journey will be at the end of this guide.

Step 1: Think about why you want to learn to code

Before you even think about signing up for classes or starting to watch YouTube coding videos, the first thing you need to do is ask yourself why you want to learn to code. Just sit down and think carefully about what you want to achieve, why you want to learn to code, and how much money and time you need to spend on it. Take into account:

What skills would you like to finish with? Do you want to become a creator of a website? Or do you choose to create mobile applications or work in the engineering of software? You must think carefully about this, as the languages you will learn will be largely dictated.

Why would you like to research code? Are you learning to code something in your spare time that concerns you? Or is there you want to try a career in programming?

How much time and money can you commit? If you only have a few hours a week to learn to code, there probably aren’t many points to sign up for a crash course. Likewise, if you want to sign up for a crash course with assistance, you must be prepared to pay for it.

Identify, write down and store your coding objectives in a secure location. These are the cornerstone for the journey between novice and master coder quickly.

Step 2: Choose the right language

Various programming techniques demand different abilities. You must learn HTML, CSS, Java, and JavaScript languages, for example, if you want to learn to code a website. Likewise, developing mobile applications requires Java (for Android) or Swift (for iOS). Choosing the right language is extremely important.

Step 3: Find the best tools to help you learn

Now that we’ve taken a look at some of the most popular languages ​​to help you figure out how to code for beginners, it’s time to research the best ways to learn them. Some of them include:

Online Coding Courses: Online coding courses, such as those recommended above, are one of the best ways to learn a new programming language. Once done, they will teach you some of the essential syntaxes of a language and how to use it. They are generally taught in a fun and engaging way, and many of them allow you to write code right in your browser as you learn.

Manuals: Code reference manuals are a great resource that every newbie should use. They contain all the syntax and conventions of a language, so you can search for things when you’re confused or don’t know how to proceed with your code.

YouTube Videos: Online videos and video guides are excellent tools to help you understand concepts that are difficult to understand. You can use them with online training or another way to start coding.

Step 4: Download a code editor

While many online courses allow you to write code in a code editor directly in your browser, you should understand that this is not how it works in the real world. It would help if you started writing your code directly in a code editor once you have completed your online course. It’s also a good idea now to get started.

Most languages have their editors of code that can be downloaded. You typically come complete with an IDE that will help you build clean, error-free code. It is also a feature. If you feel that it is simpler, you can write simple languages like HTML and CSS directly into a plain text document.

Step 5: Practice Writing Your Programs

Once you have a working knowledge of your choice’s language, you need to start creating your programs and projects. While you might feel like it’s a long way off now, you’ll be surprised at how quickly you progress once you start learning.

You can start developing a program or project based on the language you studied. For example, you can choose to create a website yourself if you learn to code an HTML/CSS website. You may also begin to develop a website to ease the learning process. However, you can begin to program your Android app or game by getting a knowledge of Java.

Remember that practice makes perfect, and that practice is the key to becoming a successful programmer. Practical, practical, and more practical!

Step 6: Join an online community

Navigating the intricacies of learning to code can be extremely difficult on your own. You can need help often. Sometimes. For instance, suppose you learn a language and find a syntax you don’t understand. By joining an online discussion board or coding forum, you will have access to people who can answer your questions and help you overcome any issues.

Step 7: Leverage someone else’s code

When you have a clear understanding of programming in a particular language, it’s time to dig deep. One of the best ways to further learn and develop your programming language skills is to unpack another user’s code.

Find anywhere with a program or code file – GitHub is a great starting point, and open it in your code editor. Please go through the code and make sure you understand each line and its function. Add comments if you need to. When you see something you think can be done differently or think that you can do something better, change it.

Once you’re done, save your edited code and upload it again so other people can comment on your effort.

Step 8: Keep Learning

In a way, programming languages ​​are just like any other language. They need regular practice if you want to master them, and you’ll forget things if you don’t use them. It is therefore extremely important to make sure that you keep learning new things every day.

Don’t get into the habit of using the same coding patterns and syntax for everything. Continue to live to learn new ways and improve your method. I try to make a habit of learning something every day. It could be a new piece of syntax, a new way to write a line of code, or just a better way to debug a program.

Conclusion

Learning to code for beginners can be fun, exciting, and very interesting. When finished, learning to code can provide you with valuable skills that you can rely on for the rest of your life. However, learning to code can also be difficult.

Social Networks Remain Essential

Social Networks Remain Essential

Digital Marketing, , ,

TikTok’s resounding success and growth in influencer marketing, especially in the beauty, fashion, e-commerce and automotive industries. These are the trends this year. For next year, influencer marketing will continue to strengthen as well as social shopping.

Like every year, its predictions on the future of social networks. This specialist in social media analysis using artificial intelligence and its dedicated platform for marketers has the largest social media database and works with more than 2,500 digital marketing teams in 100 countries.

First observation, TikTok has become essential. This photo / video app reached 1 billion downloads this year. “In 2020, we can expect to see TikTok progress in a dazzling way, thanks to very effective marketing campaigns and investments in the commercial conquest of new geographies.

This rise in power is explained in particular by the fact that TikTok is the largest advertiser on Snapchat and the second on YouTube

The power of influencers

But TikTok’s reputation is tarnished by the use in advertising campaigns of videos of users who have not been notified or paid. More recently, US lawmakers have expressed concern about the potential threat to national security the application could pose.

Another observation is that influencer marketing is still on the rise, contrary to popular belief. “Influencers” can be all kinds of people, from prominent politicians to DIY enthusiasts. In social media marketing distinguishes three types of influencers, based on their audience size:

Micro-influencers with more than 1000 followers;

Macro-influencers with more than 100,000 followers;

The celebrities who exceed one million fans.

Their impact is very strong:

94% of marketers say influencer marketing works for their business;

51% of marketers say they attracted higher quality customers through influencer marketing campaigns.

“Consumers are increasingly trusting comments and reviews before they buy. This situation is a huge opportunity for influencers and brands who team up to create content that speaks to their audience.”

Facebook, essential

Many major beauty, fashion, e-commerce and automotive brands have used this process for their campaigns and have claimed that these strategies have paid off. Investments in this sector are estimated to increase next year and will make influencer marketing a $ 10 billion industry by 2020.

“The year 2020 might well be the year of the advent of social shopping. More and more customers are shopping directly from social media instead of going to an app or an online store after discovering a product on social media

Finally, Facebook remains essential. “Our data shows that even though marketers have increased their spend on Instagram, over 60% of all total ad spend is still going to the Facebook News Feed. The Instagram feed comes in second position far behind with 20%. Overall, brands only spend around a third of their total budget on Instagram, which is the most engaging platform. This increases the question of whether brands are really getting the most out of their investment,
Social shopping, a take-off scheduled for 2020

Shopping-related content is proliferating rapidly on social media,

The platforms are responding by adding more features to facilitate e-commerce.

As a pioneer, Instagram launched a Shopping feature for certain brands, offering companies an immersive showcase allowing their audience to discover and explore products as well as follow a link to finalize the act of purchase.

WhatsApp, Facebook Messenger and Facebook Groups already offer customer management support tools so that all marketing activities, from product discovery to after-sales service can be centralized.
