Not that many changes overall in my niche.
Several small players, myself included have lost 10-20 places on manys SERPs and in general the big players have stayed where they were - and filled up the spaces vacated by the few that dropped. My traffic is down around 35% and the gains look to be spread fairly evenly across many sites that will not notice a difference.
I did at least get a smile when I found one new site that has been around since 2005 and had never been on my radar before. It hit top spot in one of the first test searches I tried, looked at it and it appeared to have almost no content. Had a look at the source and found loads of stuff with a class of "hide", when I examined the CSS found that there was a load of nonsense with an offset of -1000px.
Brilliant. Thanks for the quality update G!
