I am working on improving this site now, but while searching, I found a site that allows me to create a blog and the site ranks high 77. If I create a blog for us and direct it to this site, will I get a high domain authority through this site? I don't know if the domains are spam or something like that.

Hi, I'm working as an SEO executive and my suggestion is, that you can use the MozBar, and evaluate a site's Domain Authority (DA) and spam score before creating a blog and linking to it. Here's how:
Check DA: A site with a DA of 77 is strong. High DA sites usually pass SEO value to your site, improving your ranking.
Check Spam Score: Ensure the site has a low spam score (preferably below 30%). A high spam score could harm your SEO.
Relevance: Make sure the site is relevant to your niche (e.g., vehicle branding or signage). A relevant, high-DA site will benefit your SEO.
Example: If you own a signboard company and you create a blog post on a site with DA 77 related to branding or signage, it could help your SEO, provided the site isn’t spammy.

In summary: Yes, a high DA site can help your SEO if it’s relevant and not spammy. Always check the spam score using MozBar before linking.
