    how does ahrefs find backlinks?
    popular answer: it crawls the web and just follows link after link

    but here is the problem: lets say you are checking the backlinks to a site.com

    you get
    backlink1.com
    backlink2.com
    backlink3.com

    you check the backlinks to every one of these: you check the backlinks to backlink1.com backlink2.com backlink3.com

    some of these have zero backlinks. for example backlink2.com has zero backlinks.
    if backlink2.com has zero backlinks, then how did ahrefs find it?

    You don't have to have a backlink for your page in order to have it in their index. Their spiders keeps crawling the whole web 24/7 again and again.

    Let's say you have 2 sites called Site1 & Site2.

    You publish articles only on your Site1 and kept the Site2 blank. You then post an article on Site1 and link it to Site2. The spiders crawling Site1 now found a link to Site2 and follows it to find the blank site. Site2 is now on their Index and their bots will crawl Site2 once in-a-while. Now you post an article on Site2 for a page that has not been linked anywhere on the web. When their bots crawls your Site2 again, it'll find the link and add it to their index.

    fBguru,
    your example contradicts your statement. you say "you dont have to have a backlink...."
    but then in your example, site1 links to site2. therefore, site2 has a backlink.
    in your example, "a page that has not been linked anywhere" is listed on site2, therefore, "a page that has not been linked anywhere" has a backlink from site2.

    The equation is pretty simple. Remove the backlink from Site1 pointing Site2 and dont renew the domain for Site2 and let it die. Now you have Site1,Site2 and the other page on their Index.

    Couldn't a site with "no backlinks" not be in their index until you searched for it?
