UPDATE: eHow comments are now indexed separately from your articles. So now the content that affects your article’s SEO the most on eHow (besides your article) is the Related Articles section and the titles of your last five articles, which are included with every article you write. This is a good reason to create separate IDs for each of your niches and choose related articles based on title keywords. Remember, you can’t go back and edit these on eHow after you save your draft or publish.
