What is a referer?

The term "referer" refers to theauthority that a search engine gives to a website or web page, based on a number of relevance criteria. This authority translates into improved positioning of the site in search results, such as Googlewhich increases its visibility and, potentially, the number of visitors.

Several factors influence the authority of a site, including :

  • The quality and relevance of the content, such as the articles in the blogvideos or podcasts.
  • L'user experience offered by the site, in terms of navigation, loading and display speed, and accessibility.
  • The quantity and quality of inbound links (or backlinks) from other well-known websites and/or websites specialising in the same subject. These links demonstrate the added value of the content and its contribution to the digital ecosystem.

How do you analyse the referer?

A number of SEO tools, both free and paid, can be used to assess a website's SEO performance. The key indicators to monitor to determine a site's authority include :


Initially created by Google, this criterion measures the popularity of a web page based on the quality and number of links pointing to it. PageRank ranges from 0 (very low authority) to 10 (maximum authority). While interest in this indicator has been waning for several years, it is still relevant for assessing the strength of a website. backlink.

Trust Flow

This index, developed by Majestic SEO evaluates the trust placed by search engines in a page's incoming links. The more a link comes from a reliable and recognised source, the higher the Trust Flow will be high, generally between 0 and 100. This criterion is particularly useful for distinguishing quality links from artificial or "spammy" links, which are detrimental to referencing.

The Citation Flow

Still offered by Majestic SEO, the Quote Flow measures the potential impact of a link on a page, regardless of its origin. It takes into account the popularity of the linking page and the number of external links it contains (the more it has, the less 'value' each link has). Again, the scale goes from 0 to 100.

Domain Authority

Frequently used by SEOs, the Domain Authority (DA) is an indicator designed by Moz. It assesses theglobal authority of a website on a scale of 0 to 100, based on the data collected by its own index of links. The DA is particularly useful for comparing the performance of different sites and determining which has the greatest SEO weight.
