Hi. A question that popped up lately is.... If i am commenting on blogs, forums and submitting articles should i change my IP address or it doesn't matter? In other words do the search engines see that if a comment or an article is submitted from the same IP address they regard it as less good content link? Or the search engines do not know this?
It doesn't matter to search engines unless you are "spamming" your website out there. As long as you practice good, clean SEO, you should be fine.
i had to change my ip addresss on two of my stores because i have a hosted ecommerce cart and somehow the cart had mixed up sitemaps, what a mess. you have a good question there about content as i have one of my blogs on a subdomain and i should really look into if that effects my shopping carts.
