301 redirect or link to website better?

Hello,

We recently discovered a random name.squarespace.com website that we set up about 12 months ago that went online (we ended up going wordpress) and realized it's actually ranking, albeit in the 6th-9th pages of google, for some of our most money keywords. Would it be better to redirect the entire website to our moneypage or just go ahead and send a link to our money page on it?

Another idea is to blast it with links and then have it link to our website. Maybe we could do the same thing and 301 redirect it. What do you guys think?

Note, we 301 redirected another website that was set up using squarespace that is exactly the same (for some reason ahrefs doesn't recognize it) and similarly ranking for keywords that is a name.com. I think it worked pretty well. Was wondering if it would be bad to have multiple 301 redirects from extremely similar sites that we own going to it.

Sorry if this comes across incoherent lol. If you need me to clarify anything let me know.

There is nothing suspicious to have multiple 301. It looks all valid to hold multiple website and later on moving into one. 301 always works good as it gets you almost 90%+ power. But linking back gives you another advantage in the sense that you can link to multiple inner pages.
