Another company that nails engineering as marketing is Moz, the leader in SEO software. Two of its free SEO tools, Followerwonk and Open Site Explorer, have driven tens of thousands of leads for Moz. Like Marketing Grader, each solves a problem that an ideal Moz customer has. Followerwonk allows people to analyze their Twitter followers and get tips on growing their audience. Open Site Explorer allows people to see where sites are getting links, which is valuable competitive intelligence for any SEO campaign.
