I noticed a very dumb change in Google's algo. For whatever reason, Google has decided to rank Edu sites for non relevant keyphrases. I'm noticing a lot of financial keyphrases that are filled with Edu homepages getting top rankings. It just doesn't make any sense; however, I guess Google is making some tweaks to their algo.
The algo is constantly changing, so small things like that happen, I'm sure it will be back to normal soon.
guys, its the recent BIG change. Read up on it if you want to be worthy "SEO". they changed big time the last week(s), SEO will never be the same. This is not your normal change, thats a BIG one. Let me get some links for you...BRB brands and gov are dominating now. here: http://www.seobook.com/google-branding
IMO I don't think edu sites get any sort of a SEO boost unless it's for an extremely uncompetitive SERP. I think their authority system is based on how many people link to you... otherwise the blackhat guys will get pages on EDU domains (e.g. from students selling their webspace, hacking into blogs, etc.) and rank high anyways. It would also affect the quality of their SERPs.
Oh guys this is always happening. What we need to do is just to continue reading and search how we can go with the new flow of google's algorithm.
edu sites have been 'spammed' heavily for some time now. It could juts be a major push by the second rank (i.e. not vi4gra, pharma) - financials, or it could be an algo tweak that has epic fail written all over it.
