Beware low-quality inbound links: Google integrates Penguin on its core aglorithm

What Is Google Penguin?
The Penguin algorithm accesses the quality of inbound links to a website. Google attempts to identify which links are unnatural and spammy.
It will penalize your website if you have a disproportionate number of low quality, inbound links.
Google used to review links only periodically (every few years). Now, with this latest Penguin update, there will generally be no wait between updates. If you can get spam links removed, Google will recognize and adjust in a short period.
It’s important that you regularly monitor the links to your website: identify links from low-quality or spammy sites as they can affect your site’s search engine ranking and local listings in Google Maps.
How can you do it?
There are several tools that can identify inbound links. Once identified, create a spreadsheet to keep track of them all. Download all of the links from multiple sources and then combine all of those links into one spreadsheet and remove the duplicates.
https://ahrefs.com/ or http://smallseotools.com/backlink-checker/ are on-line service that provides a list of links to your site.
Open Site Explorer (https://moz.com/researchtools/ose/), by Moz, will also provide a list of inbound links.
Using multiple sources is necessary because even Google Search Console (formerly, Webmaster Tools) won’t include all of the links to your website. By using multiple sources, most of the links are identified.
The next step is to review your list of inbound links.
If, for example, you hired an SEO company a few years ago and it listed your website in free, low-traffic directories, then you might want to mark those as spam.
Remove low-quality inbound links by contacting the website owner and asking him to remove the links, or use Google’s disavow tool (but be aware that this is an advanced feature and should only be used with caution. If used incorrectly, this feature can potentially harm your site’s performance in Google’s search results!).
There are two options to ask websites to remove low-quality inbound links:, manually identify the site owners and email them directly or use a tool like https://www.rmoov.com/.
With Google rolling Penguin into its core search algorithm, when you get spam links removed, Google should recognize it timely and reward your site with better rankings.
Previously, Google took up to two years to update rankings after such links were removed. This new update is therefore a welcome relief.
Of course Penguin isn’t just about links. The goal of the Penguin algorithm is to clean up and discourage web spam.
Certainly web spam can be unnatural inbound links. But it can also be over-optimization tactics and content on websites that normal visitors don’t view, such as unreadable text that’s full of keywords.
