Do you trust all the links pointing back to your website? In regards to SEO, having quality links pointing back to your site is critical and Google enforces that these links are indeed from quality sources. In the past if site owners suspected they were receiving shady links from questionable sources it was necessary to launch a site rescue op to search, find and destroy such links to get back in Google’s good graces. Google generally points out unnatural links when there is evidence of link exchanges, paid links or other link schemes that violate Google’s quality guidelines.
