Google seems to be taking steps to assure that ‘Made for AdSense’ sites which are unfocused, decentralized and give no real value to the searcher; are not listed in Google results (again, I said taking steps).
The owner of a site, AlkenMRS.com, was looking for an explanation of their de-indexing in Google Groups, thinking it was a technical problem, when Adam laid down the law, showing that the problem was lack of quality, focus and trust.
If you, as an independent observer, came across such a store online, would you trust it anymore? If not, why should Google see this as an important and relevant site?
The reductions in rankings you’ve experienced are not going to be reversed by simple technical or structural changes. You may wish to focus your efforts, add compelling, original, and substantive content or tools, and *then* file a reconsideration request.
It’s an old rule in SEO to build websites geared towards the consumer, or end user, and not specifically for search rankings. It’s good to see that Google is still sticking to its guns. Let’s see if this transpires to the junk sites and search results across the board and not just for high dollar search terms.
