Do you think so? I don’t think Facebook has gone so much popular that it changes the meaning of Book. I mistakely searched for Book today (which I don’t search normally without long tails). And I was shocked once to see the result. Not so much shocked but many things started playing in my mind. As trying to gain more knowledge in own field, many questions arised in my mind:

1) How could ‘book’ refer to ‘Facebook’? It is totally useless result returned for me.

2) Is PR everything for Google?

3) Why would user search Facebook with keyword Book? They could mistakely type ‘Face’ in Address bar and ‘book’ in Google’s keyword submission form in rush. But such users can again type ‘Facebook’ in address bar. But those users who are searching for books can be misguided as more than 50% users click on first result.

4) Facebook is normally referred by FB but I haven’t heard saying book ever. So, why was such result returned?

I don’t know exact answer for all those but I am sure that Google still needs to develop more algorithms and try to understand search queries.

But I am still happy to know that Google is just a bot
