What system can be used to audit sites .

I work as a freelancer that is, I work remotely. I understand the various orders to promote any sites as well as web sites or telegram channels. I use SEO marketing that is selecting the right sites to promote quality links. At the moment I use the system SEMrush. Allows you to determine the visibility of the resource on the keywords in Google. The service is convenient for building reports and conducting audits of the site. However, SEMrush has one big minus: it does not work on Yandex. Yandex is very often used . And this program is free and gives poor quality site audit . And for this I am looking for a suitable paid quality tool .

I use Serpstat and Sitechecker, but now I switched to Sitechecker more... because it is more convenient for me, you can find a comparison of these tools here sitechecker.pro/serpstat-vs-sitechecker-comparison/

I'm wondering if SEO tools can be effectively used to audit a website if purchased through group purchasing? Will using these group purchasing tools provide a quality site audit?

These tools helped me develop an optimization plan that greatly improved my site's search engine visibility. Several colleagues and I teamed up to purchase an advanced SEO tool. We were able to reduce costs significantly through group acquisition. The tool has proven to be excellent at keyword analysis, technical error checking, and link evaluation. Thanks to Seo Group buy tools we were able to spot several problem areas on the site that we might have missed if we had used less powerful or less accessible tools.
