SEO for a Q&A site differs from SEO for blogs in several ways. Firstly, unlike blogs, Q&A sites require users to ask and answer specific questions, so the content is much more targeted and focused. This means that the keywords used to optimize content need to be tailored to specific questions and answers rather than broad topics. Additionally, a Q&A site will likely benefit from fresh content more than a blog, as questions and answers can become outdated quickly and need to be updated regularly to remain relevant. Lastly, user engagement is much more important on a Q&A site, as users will be more likely to use the site if they receive helpful answers to their questions. This means that SEO optimization techniques need to focus more on creating content that encourages user engagement, such as authoritative answers and compelling questions.
