First of all, thank you everyone who showed interested in my previous article about Negative SEO.   In my previous article, I discussed about protecting your site from Negative SEO and one of the most common method people use is buying thousands of low-quality links and pointing it to their competitor’s website hoping Google will see that and penalize their competitor.

But here is the problem; how do you know which link is the unnatural link?  Whenever Google detects an unnatural link, they will send an unnatural link warning email to Webmasters so that they can remove it as soon as possible before it start hurting their ranking.  However, if you have a big link profile, how can you tell which link is harming your site.

Unless you are monitoring your website since day one and know what sites are linking to you or you simply don’t build links at all, Matt Cutts from Google’s Search Spam team recommends the following ways to locate unnatural links.

2 ways to locate unnatural low-quality links:

1.  Google updated the Webmaster tool which allow Webmasters to sort links by most recent.  This way, even if you don’t constantly monitor your backlinks, you will at least know the date your site received a particular link and compare it with when Google detected the unnatural link.
2. Google will try to include examples of unnatural links within the unnatural link warning email they send to the Webmasters so that the webmasters have an idea of what type of links are low-quality.  They can work off from the examples and try to remove the unnatural links.
