I have an seo question for my site http://www.quoteforinsurance.com. I made some rather big html code changes to my site (moved all the content to the top of the code) back 2 weeks ago now. Google indexed the changes within 24 hours. I have now dropped in the SERPs and I'm doing a yo-yo thing now. How long does it usually take for the SERPs to balance back out?
I don't have anough sites to know what "usually" means, but I took one outbound link off the top of the home page and 10 others (of 120 total pages) and fell from #2-3 at Google to somewhere below #30. I was gone for about six weeks. Dropped my AdSense income by about 2/3's. Continued ranking for low competition, niche, keywords were all that kept things going.
From my own experience it often happens that google drop my websites for 1 - 5 days before the boost.
