What does SEO mean ?

SEO (Search Engine Optimization) means in French: 'Optimization for search engines'. This term defines all the techniques used to improve the position of a website on the search engine results pages (SERP). It is also called natural referencing.

The objective of an expert in natural referencing is to improve the visibility of the websites he supports by making them gain places on search engines (Google, but also Yahoo !, Bing, etc. .). The goal is to bring together Internet users interested in products / services or informative content.

We say that a site is well optimized or referenced if it is in the first position of a search engine on the desired queries.

Textual content of your site

On-page or on-site optimization is the set of techniques aimed at improving the quality of the content of a website / web page. Several elements need to be perfected from your keyword strategy :

  • Title tag
  • Meta tags (Meta description, robots, keywords)
  • Semantic markup (H1-H6)
  • links / URLs
  • Page content (Body)
  • Internal mesh (internal links)

W3C compliance

Making your website conform to W3C specifications is paramount to controlling its quality.

To comply with W3C standards, your website must take into account several parameters:

  • Declare a doctype recognized by the W3C
  • Respect for semantics
  • Make your site accessible according to WCAG specifications
  • Test and correct your pages

Speed ​​optimization

Have you ever heard of Google's Red Slow Label? For almost 10 years, the web giant Google has started to factor the speed of loading websites into its SEO rankings.

Google thus promotes the referencing of the sites and web pages that are the fastest to load. On the other hand, it penalizes web pages that take a long time to display. How? 'Or' What ? Quite simply by lowering their positioning in the ranking of search results.

In addition, a site that is too slow can be granted the famous label: Red Slow Label, a call sign marked “slow” in bright red color which is visible during Google searches. This indicator is visible for searches carried out on mobile in order to warn Internet users of the slowness of a site.
