Sudden drop in search engine traffic.. why?

I installed vbseo around september, it started out quite well as you can see from the stats below, but during the last month search engine traffic (about 90% from google) dropped to nearly nothing compared to a few months ago.. I have no idea why this is happening, any ideas??



When I search for my own site enjoycg.com, the results used to be all right, showing forums in a neat list, but right now the first result is a link to an old part of my site which hasn't been online for more than a year.. then there's one link from vbulletin and the rest is from other websites, it's like google suddenly dropped most of my site.

Boy that sucks!

I take it that graph is just your seach engine traffic not general traffic?

Can you post a search engine break down for the same period?

Have you lost any major backlinks recently?

That's just the search engine traffic, of course my overall traffic decreased quite a bit as well because of this.. what do you mean by a search engine break down??

is your topic seasonal?

n/m, just saw the url...


you do have some code issues...

Thanks for mentioning that, I'll work on it. While searching for a possible solution I found out that the sitemap generator wasn't working properly for a while, maybe that affected google a lot? I've fixed it now but still wonder if that could have such a huge impact on traffic..
