Right ive been hit by updates and penalties before and had problems with ranking in certain niches so I know how things can change at the drop of a hat. Now this time it's very different and quite odd. I noticed this 5 days ago and since then my serps have been going mental! I have had a site for a few years now and for the past 2 months 6 of my pages have been on page one between 1st and 5th place. They are fairly competitive niches but not to the point where anything malicious has effected my rankings, like I have seen on some of my other sites. No bad links are showing up either. The strange thing I have noticed was a drop of about 60 places. So first I was thinking, ah ive been hit lets wait a few days and see the result, I have seen it before so know the drill. Since then I have gone up and down repeatedly, it's acting like it's stabilizing now in the 20s some are in the 40s. It does seem to be growing everyday and I am using my own serp bot to monitor the results. Now from a full crawl of 100 links I have noticed that even big names are down in the serps, we are talking about huge niche sites here, where they were once no1 for months on end they are now on page 2/3. I then browsed further and the ones that are in the top 10 are mainly url spoofs of .edu sites. Now really, this can't be right can it? I thought these were out right banned from serps due to the fact it's just bloody ridiculous. Im just asking if anyone has noticed anything odd. Im not giving niches or site information away just wondering.
