I've searched the net and wasn't able to find a solid answer to this. Is it poor practice to seek out blogs that are related to your site, and post comments relevant to the particular blog post, in order to gain backlinks?
For example, if my site was called "TAFSpecialists.com", or "The Ant Farm Specialists" and I posted comments on relevant blogs using the name The Ant Farm Specialists and TAFSpecialists.com as the website URL, will Google penalize my site? Or is it beneficial, as I originally thought? I'm not spamming blogs, but rather contributing intelligent comments to their blog post. Thoughts?
