Definition of a backlink
A backlink (is a hypertext link placed on an external website that points to your own website.. This is an inbound link, as opposed to internal links, which connect different pages within the same site.. For example, if site A inserts a link to site B, then site B receives a backlink from site A.
The role of backlinks in SEO
Backlinks play a central role in Search Engine Optimization (SEO). They are considered by search engines as votes of confidence or recommendations: the more quality backlinks a site receives, the more it is perceived as relevant, reliable and authoritative on its subject.. Google, in particular, uses backlinks as one of the three most important ranking factors to position sites in its search results.
Google's famous PageRank algorithm was designed to evaluate the quantity and quality of backlinks pointing to a page, which directly influences its visibility in search results..
Types of backlinks
There are several types of backlinks:
DofollowLink juice: transmits authority to the target page and is taken into account in SEO rankings.
Nofollow: tell search engines not to transfer authority to the target page (used, for example, for sponsored links or in comments).
Text linksbacklinks inserted into a text.
Image linksbacklinks integrated into a clickable image.
Backlinks from social networkslinks from platforms such as Facebook or Twitter (often nofollow).
Quality vs. Quantity
Not all backlinks have the same value. Search engines prefer backlinks from reputable, authoritative sites dealing with topics similar to yours.. A relevant, high-quality backlink will have far more impact than a multitude of links from unreliable or non-thematically-related sites. Since the introduction of Google's Penguin algorithm, quality has taken precedence over quantity, and link-building practices (link farms, link buying) have been penalized..
