When i checking my blog backlinks using Google web master, Yahoo Explorer and other backlinks checking tools they show some sites pages, but if i visit that web site page i can't see my blog URL (backlinks). So why my blog backlinks invisible?
That's the problem because these data are not updated on regular basis. Once the crawler finds your link on a certain page it adds that page as your backlinks. But if for certain reason our anchor text is deleted or moved to any other url then you faces the problem of not finding the link.
