SEO glossary

.htaccess:

The .htaccess file is a Linux configuration file for a web server. It is the file that helps the web server to set up traffic using the Http protocol. It is a very important element for optimising urls for SEO purposes.

Redirection 301:

A 301 redirect is an error code indicating that content has been transferred from one URL to another. This is particularly common when a website is migrated. The 301 redirect allows search engines to adapt the indexing of your content when the error is detected. In this way, search engines will no longer analyse the old url, which is now empty for the website’s referencing.

The 404 error:

When a url is requested in a browser but does not exist, or has been deleted or modified, the 404 error code is returned. Since this is a recurring error, it is useful to build a custom 404 page for a quality user experience.

Backlink:

These are all the links pointing to a website from outside (other websites, social networks, forums, etc.).

The baseline is the slogan that accompanies the name of a website. It is often displayed next to the logo in the navigation menu. It provides short, simple information about the site’s activity, as well as having a marketing dimension.

Keyword:

A keyword is a word or phrase on which you want to position your content when it is searched for on search engines.

The alt attribute:

The alt attribute is a descriptive text that replaces a visual, such as an image or video. It is very useful for understanding the associated content for SEO algorithms, but also for people using assistive reading software. It is also the element displayed by default when pages on a website do not load correctly.

The craw:

Crawling is simply the action of exploring web content. Crawlers are search engine robots that come and study the content of a website.

Anchor links:

These are links for browsing the same page. By clicking on one of them, the browser redirects to a specific section of the current page.

Organic links:

Organic links are links that are spontaneously shared by Internet users who like the content. Typical examples are posts on social networks or shares on blogs and forums.

Link bait:

Link bait refers to a link to content that is intended to be shared en masse.

Link farm:

Long tail:
