Sorry if the title seems misleading but it does relate to spam. I've been receiving spam comments on my websites and I usually just delete it until recently... I spoke with a few IM buddies about the idea of spam and how to use it. Anyways, if anyone is in the SEO business/ knows how to provide SEO services for others, you can use the spam. You've seen it, you've done it yourself, but you shouldn't comment spam on your money site. I've seen an increase lately of comment spamming to their money site and the website owners of the site that is comment spamming is our potential clients. I've tried it out on 20 different emails. 3/20 website owners wanted to switch services because they didn't know what they were doing or just hired fiverr gigs to their money site. Anyways, make use of the spam you receive. I'm sure this isn't the first time someone thought of this but it's a reminder. So to sum it all up, if you're involved in the SEO business and know how to properly do SEO, the next you receive a spam comment to your website and it links to a money website, send the website owner a proposal.
