The year was difficult for those who dedicated themselves to the practice of link building. Google changed its parameters for validating valuable links and weighed its hand when choosing which links were spam and which were not. Everyone was harmed and found themselves forced to redirect their practices to new methods. These methods have proven to be more laborious and more expensive, but much more necessary than before. After all, the value of a link has gone up! Guest posting has proven to be the right bet for those who have already practiced it before and is, until now, a safe technique, as long as the content posted is original. The inevitable disadvantage, however, is that for a good idea to last, practitioners cannot overload it.
Guest posting quickly became a “spam” technique, as many professionals always seek to automate the practice, without real interest in the content or blog, or even in the special-data name of the linked company. What mattered was always the link, which automatically had its value reduced and even forced Google to once again review its link evaluation guidelines. And Matt , head of Google's department, says this on his website. In this post, he talks about how “back in the day” blogs were reputable sources, just as guest blogging was something that required credibility. Today, however, the practice has become a purchase of advertising space without the user/reader knowing.

I quote here, translated, the conclusion reached by Matt in the post in question: “So, to wrap things up: guest blogging doesn’t work anymore; became very “”. In general, I wouldn't recommend accepting a guest post unless you are personally very willing to recommend someone, or know the person doing the posting well. Likewise, I wouldn’t recommend relying on guest posting as a link building strategy.” When you read the entire post from the Google engineer, you understand better: it doesn't mean that guest posting is dead. But it does mean that the quality of these posts will determine the quality of the links, and since the majority of these links can be considered spam, he recommends skepticism when accepting to publish guest posts on your blog. But take it easy! is not saying that promoting your site is prohibited.
