I've had a few books reference SeoMOZ for help when researching quality of back links. However, the cost, $99/month seems really steep for what's offered. Am I being a cheap skate or is this really worth it? I run a small business doing website design in Kalamazoo, MI and every customer I've had has asked about SEO so I'm making it a priority to learn more and become proficient.
Does anyone have tools similar to OpenSiteExplorer.com that they use?
Thanks for your time reading this!
