On January 20, 2014, Matt Cutts, Google's spam fighter, published an article on his blog entitled " The Fall of Guest Blogging for SEO ", where he warned us that we cannot use Guest Blogging as a strategy to get links and thus improve SEO, since Google may consider this action as Spam and thus penalize us.
Why haven't many people followed Google Guru Matt Cutts' recommendations?
Why do we still use Guest Posting as one of the main ways to get links and improve SEO?
To try to answer these questions, I will analyze 4 relevant blogs in the sector that allow Guest Blogging and analyze the evolution of the last 6 months, since Google announced that we should stop using this practice to improve SEO.
Case Analysis 1. Pure Marketing

The graph of the origin of the visits is quite natural, with organic searches on Google being the source that provides the greatest number of visits.
Conclusions
Puro Marketing makes good use of Guest Posts without running the risk of being penalized. In addition, when we upload the content to the Puro Marketing editor, it will be transformed into plain text, eliminating traces of links.
