Yes, of course. Altavista used to be the best, then Yahoo, then Google....Baidu is on the rise...many more to come. What goes up, must come down. If anothe rsearch engine comes out with another cool idea or improves on the system that Google has...they got the market. I think MSN will be the next big engine. They slacked a bit, but they made IE demolish Netscape when everyone thought netscape was supreme ruler. They can do the same to Google..I personally think Google are bullies and one of these days they are going to piss off the wrong person/company. I am not a big fan of MS either, but at this point, they are the lesser of 2 evils.
Yeah, but it will take a long time from now since Google got the best of the best working for them. I can't wait to see a new search engine trying to compete with them.
yes there are a lot of strategies in SEO..like Google add sens tools..just try to navigate it will help
