Estimated number of links
Google will never reveal all the links to a website (albeit it will show some links in Google Search Console).
In order to get this information, we use Ahrefs (Ahrefs).
It is a very powerful link research tool, second only to Google.
It crawls the entire web 24/7 (much like search engines do) and stores petabytes of information about live websites — how they link to each other and what keywords they rank for in search results.
It is thus able to calculate how many links a page receives from other other pages.
Usually, the greater the number of websites linking, the more authority a given web page is likely to have.
Please note that we have reported the number of links so that each website counts as “one vote”.
So, irrespective of whether you have one link or multiple links from the same website, they will all count as “one vote”.
