According to Search Engine Land, Google has been sending out warnings about having “artificial” or “unnatural” links pointing back to your website. Many people have been getting warning messages from Google about link violations. According to Google, although it may appear that Google is just beginning to put its foot down on bad link networks is nothing new. Google has been silently distrusting links for some time, however now it’s decided to be more vocal about the action it’s taking against these types of link networks.

Search Engine Land gave this example of one of the violation warning messages from the Google Webmaster Help forum:

Dear site owner or webmaster of _____,

We’ve detected that some of your site’s pages may be using techniques that are outside Google’s Webmaster Guidelines.

Specifically, look for possibly artificial or unnatural links pointing to your site that could be intended to manipulate PageRank. Examples of unnatural linking could include buying links to pass PageRank or participating in link schemes.

We encourage you to make changes to your site so that it meets our quality guidelines. Once you’ve made these changes, please submit your site for reconsideration in Google’s search results.
If you find unnatural links to your site that you are unable to control or remove, please provide the details in your reconsideration request.

If you have any questions about how to resolve this issue, please see our Webmaster Help Forum for support.
Sincerely,

Google Search Quality Team
