usually only 1 ad per page either in middle or bottom of the page.
Same here, my site that suffered -30% traffic loss usually has one small horizontal banner in the middle and one adlinks. I make it a point for my users and my self respect not to have spammy sites. I usually ignore Adsense insistence on adding bigger ads. Only very recently did I started to use big squares on one site with declining CTR, which hasn't been affected by the update.
The sites I design are all squeeky clean
Same here, hand coded XHTML, CSS, no tables, clean and minimal code, thoroughly tested with all browsers, good and lightweight graphical design.
In fact the sites I design have never been affected by any update and I've been a designer for over 11 years.
Roughly the same story. 10+ years in the business of working on the web, about 5-6 making content web sites on the side. First algo update that hurts me like that.
We should hang out. lol.
I'm not going to do anything in the short term but it really, really sucks.
