I'm stumped and I need some more things to check. My site is not showing up for any searches that it was showing up for before - except a search for the name of the site and a few very obscure searches.
A site: command shows all pages are still indexed. Don't see any problems with googlebot, the only SEO that I use is what is reccommended by Google, I use descriptive meta tags that reflect the content of the page, try to get relevant sites to link to me, stuff like that.
I've been over all of the outlinks and inlinks, I see some spammers linking to me but nothing big. I checked at copyscape, 2 sites have copied some text, but no big deal. There are no www issues or duplicate content issues except I did have a paragraph of copyright info that appeared in the footer of each page. I removed that just in case.
A lot of the site is original illustrations with not a lot of text on the pages, that might be a problem, but these pages were showing up before. Around 25% of the pages say "supplemental result" when I do a site: command.
This site has been online since 2002, was getting around 100 refferals a day from google, has 300 backlinks according to siteexplorer and has about 400 static pages so it was pretty easy to look over, I've been over it again and again for 2 days and I can't find a thing wrong with it. What else can I check for? Should I email Google?
