Major Google algo update coming – a few weeks left to get your site ready for Penguin 2.0.

Analyze and clean-up your link profile 

First and foremost, Penguin update combats spammy and low-quality backlinks.
The new Penguin version is expected to use even more sophisticated techniques to spot spammy links in your backlink profile, so even if your backlinks seem quite OK for Google right now, you'd better run another thorough audit before Penguin 2.0 arrives.
So the first thing to do now is to analyze your site's backlinks, identifying any potentially spammy links and getting rid of them before the update.
The basic rule here is to avoid backlinks that:

Come from sites built exclusively for the purpose of SEO.

Use overly-optimized anchor text.

Come from adult or other "bad neighborhood" websites.

Come from sites that are irrelevant to your own.

Now here's how to find and identify suspicious links pointing to your website. This may take some time, but recovering from the update will for sure take you much longer.
