Optimize your pages indexation on Google

What is indexation?

Indexation is when Google references your website on a specific keyword. The indexation must be distinguished from the ranking which takes into account the rank on which you are in a SERP. 

Which elements can block the indexation of my pages? 

1. The meta Noindex tag

Meta Robots and Meta GoogleBot tags forbid the indexation of a page when their value includes Noindex. This HTML tag is located in the <head> of your page.

<meta name="robots" content="noindex">
<meta name="googlebot" content="noindex">

2. HTTP X-Robots-Tag headers

The HTTP X-Robots-Tag header forbid the indexation of the page by search engines when its value includes Noindex. This indication is modifiable in the configuration of your web server. 

HTTP/1.1 200 OK
X-Robots-Tag: noindex

3. The canonical URL

The canonical URL is the preferred URL of your page. If this URL is not valid or corresponds to an URL different from the current URL, the current URL may not be referenced.
