Wouldn’t it be so much easier to just buy a site that similar to yours and redirect all their backlinks to yourself … you might try point them to relevant content or simply to your homepage. I do that. I’ve lead clients to try it with great results. But it seems back ops and the more prolific SEO channels out there generally ignore redirecting or they discourage it.
Consider Yoast … they are hands down number one in SEO page optimization on a WordPress site. There blog then largely is widely accepted and they have said relatively nothing on the matter … but would it surprise you to learn they actually do it themselves? Something they do but they’ve never made a blog post about it.
Heres a video I made where I show others redirecting backlinks from now functionally defunct sites to their homepage.
Now what? Well so now you need to learn what sites to register and to redirect. This involves a minor audit of the site first. But thats another video.
