Help! Sudden disappearance from Google UK rankings

[mr27]

My website has been going well, and in the first week of January averaged 2943 daily Page Impessions, and 924 daily Clicks on its Google Adsense ads. About two thirds of its pages appeared in the top 10 returns for the relevant phrases in Google UK.

Then on January 10th its pages suddenly ceased to appear in the top 10 Google UK returns for the relevant phrases, and the traffic collapsed. On January 11th there were just 344 Page Impressions and 74 clicks on its Google Adsense ads - around a tenth of the previous level.

I believe I am carefully adhering to Google Webmaster Guidelines, and I know of no reason why my Google rankings should have suddenly collapsed. Any ideas, please, as to why this might have happened, and what I can do to put it right?

Almost impossible without seeing the site, see how your site fares in Y! and M$N - if they're OK, the likely contender is links.

Check all your links, and remove those you wouldn't really recommend to your visitors. Even paid links.

If you've been a member of any link exchange schemes, leave - even one-off reciprocals should be examined carefully.

Google is really tightening up on link abuse - doesn't mean YOU abused, but if you exchange links with someone who got caught, your links become a 'bad neighborhood' and you suffer too.

Then check again.

Good Luck ;)
