Your competitor may buy content of poor quality with links, ordering publication on services with terrible SEO ratings. He may also order spamming of the poor reputation of the forum with comments that are not only obvious word of mouth (which, in this case, will not help you in any way), but also do not fit the topic of the discussion, or even: the section itself. After all, there is nothing like talking about engine piston rings in a thread about microneedle mesotherapy of facial skin!

How SEO algorithms relate to page positioning: the Penguin system
In 2012, the link analysis system underwent a revolution. Previously, Google did not take into account links from pages with questionable content or those that were simply poorly rated by robots. At that time, the Penguin system came into effect, assessing the quality of link building. It is not hard to guess that links from spam sites (heh: the 21st century dump!) began to drastically worsen Google's rating. Only valuable and unique content, published on good-ranking services, leads to improvement in this case.
How important is Penguin? In 2016, Google integrated it into its main ranking system. So it is no longer just a consultant working for hire, but rather: a key cog in the machine.
