Welcome to the Q&A Forum

Hi Falguni, If you're looking for white hat SEO (which is what you'll find at Moz) then there's really no generic forum(s) that will send you traffic that matters. Link building via forums has to be done in a particular way anyhow to avoid being spammy and these forums should be specific to your niche. Essentially what this means is if you're working for a finance company, the forums that could be used correctly for them would be different to an accommodation website or a plumber. Locating the best forums takes a bit of research - what you're looking for is an active forum specific to your topic that you can genuinely contribute to, much like I'm contributing here right now, though I do this for community engagement and a mutual sharing of knowledge rather than traffic or leads.
