... if they give out too much information to people to fix their sites it just makes it easier for their results to get spammed.
There's some sites that have been using questionable techniques that have gotten a boost from this, and their techniques provide a possible "how-to" for spammers.
Example: a site that didn't rank well for a phrase for which I did (until last week) rank well. Now this site is in the top ten.
The URL is a keyphrase, "Acme-123.com", where Acme is obviously the manufacturer, and 123 is the model number. In another thread TheMadScientist thought that appearance could play a factor with some sites. Well, this one looks like Helen Keller designed it using some 1990's sites as a template.
There's only four pages to the site. The navigation menu links to other sites that are owned by the same company, and the links are anchor text ("Acme 456 widgets") and the URL's are keyphrases ("Acme-456.com").
There are no ads on the site, unless you consider the navigation menu as an ad (which I do).
As far as a link profile, the site doesn't have one, except for the network of links from the many sites--all of which look exactly the same--that the owner has created.
I think this is a good example of how to spam the new results, as I've seen similar schemes on other good-ranking sites.
