How do I use the Mollom Module for SEO?

https://www.drupal.org/project/mollom

The Mollom module and service combine to create an “intelligent content moderation web service.” It uses data collected from the 60,000+ websites that use the service to figure out if comments or content posted on your site are spam. If it is, it blocks it. If Mollom can’t determine if it’s spam or not, the module will use a Captcha and ask the submitter to prove they are a real person. Mollom boasts a 99.98% efficiency rate which means that for every 10,000 spam messages posted; only two will get through. Spam on your website negatively affects your Google ranking. Google prefers to send visitors to non-spammy pages. Spam comments can sometimes be used to inject unwanted code into your site. Fortunately, Drupal 8 has come a long way in preventing this kind of attack. Blocking spam with Mollom is an excellent way to protect your investment in your website. If you don’t use Mollom (or some other spam-prevention service), then you should carefully moderate every submission to your site— comments, content, user accounts, etc.
