As Microsoft added live Twitter search results to BING search results page and Google promptly followed, Twitter becomes a very useful SEO tool which can bring additional traffic to your website. The main thing here is that the data is live – as far as I understand, search index is updated by Twitter directly, so the moment you tweet something, others will see it in the search results. Awesome!
Personally, I’m very afraid that Twitter will be seriously bloated with spam. And I don’t know yet how Microsoft and Google are going to filter out all the spam. Or maybe that’s something that Twitter will do? We’ll see.
In any way, Twitter will gain even more popularity and influence.
