Is it possible to purchase 2 niche editorial link insertion on the same website's 2 post

A few days ago I inserted a link to the home page of my niche site on a trip description post on a travel site.

Now the keyword ranking of an internal page of my same niche website is on the 2nd page of Google.

I want to insert a link to the internal page of my niche website on the review page of this travel website to improve the keyword position. Is this okay? Can you see a more ideal effect?

Or is it recommended to ensure that my niche website only corresponds to One website with a root domain name, and find other websites to insert links to that internal page?

It won't be as useful as the 1st link, but can surely make a little boost neither won't be spammy or cause any problems,
If you're willing to pay the exact same price for the that link, you probably should get a link from a different website,
All depends on the website, KW difficulty and other factors in question here

Adding a link to your website's inner page in the travel site's review can help your Google ranking. It's cool to do, just make sure it fits well. Also, spreading links to your page on different good sites can make your site show up better overall.
