Is a dofollow backlink from an 82 DA domain with 500k mo visitors good?

I have a new website and I'm looking to increase my credibility in search engines, particularly Google, by obtaining quality backlinks. There is a website within my niche that offers a sponsorship opportunity for $20 per month, which includes a photo and a link of my choice on their homepage. These links are dofollow and not labeled as sponsored. The website generates around 500,000 unique monthly visitors with an 82 domain authority, and the homepage receives approximately 100,000 views. Although I don't anticipate many clicks on the links, as they will be among others, I'm wondering if this strategy will positively impact my website. Additionally, I'm considering whether linking to a specific blog post or my homepage would be more beneficial in terms of boosting my own website.

A dofollow backlink from a domain with a Domain Authority (DA) of 82 and 500,000 monthly visitors is generally considered a good backlink. It’s particularly valuable if the website is relevant to your niche.

While the price of $20 per month seems low for such a high-traffic site, it’s possible that the website is a non-profit organization with limited monetization options. It’s important to ensure that the website is legitimate and not engaged in any shady practices.

The placement of the link can be strategically considered. Linking your homepage to the website’s homepage could potentially increase your website’s overall authority and visibility, while linking a specific blog post to a relevant blog post on the high-traffic website could improve the ranking of that specific blog post. Ultimately, the best strategy depends on your specific goals and the nature of your website.
