Forum links are still a popular tool among many agencies and SEOs to build topic-relevant backlinks at a low cost. The links are especially suitable to increase the popularity of old websites and create a solid start for new projects.
Forum backlinks are one of the few methods to organically promote your website and, as a result, get an increase in the recognizability of your brand.
To answer this question, the first step is to check the visibility and reach of the forum where the link will be placed. Because only if these two aspects are qualified, search engine trusts the website. This trust is in turn the basis for successful forum link building and leads to a better ranking.
Secondly, you should look at the link metrics of the corresponding website. Because only a page with strong backlinks can pass on sufficient traffic to your domain. However, in order to analyze comprehensively, this data should not only be checked on the domain level, but also on the URL level.
All in all, it is not easy to find a forum that suits your needs, especially if you try to do it yourself.
