As informed by the google caffeine sandbox site, google is rolling out the new search architecture codenamed caffeine through out their data center slowly and will push across all data center after this holiday season. Watch the video below for Matt Cutts' explanation on google caffeine.
As described by this quote from Black Hat Forum, we are heading to the right direction,
Google caffeine is up for fighting with real time searches on twitter & faceboook
Add / update content frequently or you may loose on some more rankings
I searched for seo in google caffeine. it showed me facebook page from japan, which was recently updated. And had some content releated to seo, but not search engine optimization, It was meant for some other abbvr.
Caffeine would more probably rely on fresh content
It seems to be giving an increased weighting on domain authority & some authoritative tag type pages ranking (like Technorati tag pages, wordpress tag pages, propeller tags, etc)
You have got to make your domain more authorative in terms of traffic, content and links.
They are also putting slightly more weight on exact match domain names. In a way, we should focus on spamming these high authority sites to get the search traffic....
We need to look at ways how we can get our links on those social media pages...
