Hey! I've read loads of debates about using onsite comments vs using offsite comments such as discus platforms which use JS and source remotely. While onsite can boost SEO because people are effectively extending your content, and offsite google can't scan since its offsite and phased after the page is loaded. My question is can your page keyword denisty be affected by user comments either by google or bing? since they are adding more words which in effect could cause your main keywords % to lower. Thoughts please.
