Penguin update deals with scanning through the link profile of a website. I will scan the links pointing to the site using tools like ahrefs and prepare a list of low quality links. I will make every effort to get those links removed like emailing the webmaster. If somehow, I am unable to remove some links then I will use the disavow links tool to devalue the remaining links from harming the site. Apart from this, I will plan a link bait strategy to get some high authority links in order to increase the reputation of the site. This will surely help a site to recover from the effects of the Penguin update.
