I may have sussed why my listings have been dropping. i have been using multiple domains and pushing them (in free directories, bookmarking, blog posting etc). for example, www.gio-goi-clothing.com will point to http://www.space-clothing.co.uk/brands/browse/gio-goi and this top level domain is what google has been indexing due to me promoting it. maybe they have worked this out and penalized me? it's happened to another domain which was happily sitting at the top spot and dropped down to page 7 now also. any experience or ideas on this appreciated. thanks
It's possible. But as far as google is concerned, you'd never know for sure. Check the webmasters control panel in Google to see if you can find any pointers towards the actual reason for this.
