Posting comments with links in Reddit may provide some benefits for SEO, but it is not a reliable or effective strategy on its own. Reddit uses the "nofollow" attribute for all links, which means that search engines like Google do not follow or pass any link authority or ranking credit from those links.
However, posting comments with links in Reddit can still provide indirect benefits for SEO. For example, if your link leads to high-quality content that is relevant and valuable to the Reddit community, it may attract clicks and traffic to your website. This can increase your website's visibility and potentially lead to more backlinks and social shares, which are important factors for SEO.
Additionally, Reddit is a highly authoritative website with a large user base and strong domain authority, which means that links from Reddit can still have some impact on your website's credibility and trustworthiness in the eyes of search engines.
Overall, posting comments with links in Reddit can be a useful tactic for driving traffic and building your online presence, but it should be done in a strategic and ethical way, with a focus on providing value to the Reddit community and avoiding spamming or self-promotion.
