Hello everyone,recently I installed an addons into my browser (Mozilla Firefox) which show me the number of backlinks counted by Google, Bing and Yahoo. From that status bar, I often notice that the ratio of counted back links by these three search engine is quite non-linear. Like now I can see that this forum is getting 33 Backlinks by Google, 1,320 by Bing and 1,125 by Yahoo. So, the question is, why this differences occurred? For backlink, which conditions does Google take in account which Bing and Yahoo doesn't? I'm also finding the same for my blog's back link which is about iphone. Google is not counting any backlinks even from relevant sites! Any explain will be appreciated.
Different search engines have different algorithms. So we cant expect same amount of backlinks from every search engines. Also different tools show different results. You will see different results.
