As with everything in the field of search engine optimization, there are also various metrics for determining the value of links.
What is link strength?
In the field of search engine optimization, link strength is a term that represents link quality. It is about information in the context of off-page optimization, whereby the influence of backlinks can be measured. For example, a valuable link can massively boost the ranking. Google sees the linking of websites as a recommendation. For this reason, it makes sense for backlinks to come from valuable sources rather than spam blogs or similar, as these have long since ceased to have any influence on Google or Bing rankings.
How can the link strength be determined?
Since Google discontinued PageRank, there is no longer an obvious metric by which the strength of a link or domain can be measured. However, it is sometimes clear, for example if it is an authoritative website in the respective subject area. Of course, there are also SEO tools to measure link strength in this regard and to understand what strengths a link has. This provides various information that can be relevant for link building.
What criteria does a search engine use for Link Strength?
Search engines use a variety of criteria or indicators to evaluate the quality of a link. These include the following characteristics, among others:
- Link spam
- Number of backlinks from small or medium-sized websites
- Age of a link
- Authority of the linking website
- Content orientation (subject area and similar)
