Well, sorta but your more likely to penalize your site instead. Google sees this as a blackhat tactic from my understanding. And the honest fact is the type of redirect. Redirects lose alot of juice and versions of the redirect pass no juice at all. One thing that would help instead which is actually still considered shady to google but much harder to deploy or detect. Is to take those sites. Build real content. Build real links. Then guest post on it from your money site. For those sites you wouldn’t have to make a ton of content think of it at a long term investmemt If you plan to manage 3 or 4 of those domains, do 2 to 4 very high quality postings, do your research, find the LTK you are targeting (most important build high relevance to your money site by ranking for similar keywords on new, fresh, non duped content).
And this network could start to collect traffic.
What is my final take?
Work on your branding, work on your social presence, work on the information your client displays. Find a way to become a content leader in your space dont just focus on “buyer intent” but also focus your content around the people who are asking a question about the nice. For instance let’s take knee braces, look for the gaps to fill in your niche like “Ultimate guide: Patellar Tendonitis”
As you cover this topic think of 4 more posts like “The top 5 knee braces for patellar tendonitis”, “Pain management: Jumper’s Knee”, “Popular ways to treat an injured Patellar Tendon”, “Most common knee injuries related to Patellar Tendonitis”.
Find high quality references e.g wikipedia for the actual terms and research, companies like betterbraces.com that have great online resources about brands.
Take 500-2k words on the main topic build that, in the top 160 words add a excerpt from one if these most related posts. Then throughout the article write up 100-200 word excerpts about each topic then internally link to that content as well.
Doing things right will always beat the cheap and dirty.
