I just wanna ask why does google remove my rankings >100. 5 days ago I have 4 keywords ranking from 20-40 but now all rankings of keywords are gone.
where do the majority of your backlinks come from? are they relevant sites? do you have links at all?
Is your site or pages very new? Are you getting links for them and promting them on the search engines? Were they important keywords, or some niche keywords and is your site under sandbox?
Add more keyphrase descriptive content to the home pages and make a more useful document structure. Also use google sitemap.
you lost your rank for the following reasons: 1. you lost a nice amount of links 2. you got banned 3. google updated/crawled your site, which they didnt in a long time - and now because of changes made to the site - ranks went down. hope it helps :>
