Reproduce the best backlinks of the competition
Having backlinks from the same domains that are already linked to your competitors can sometimes be a challenge, but most of the time, if the dissemination process is well done, you can get great results.
Note that all the backlinks of your competitors are not good, even if they rank higher than you in Google. Make sure they do not get links that violate Google's guidelines and only try to replicate those that are of high quality.
