If you’re relatively new to the world of search marketing and link building in particular, this comprehensive A-to-Z guide will help. It covers everything from bait (otherwise known as link bait – content designed to naturally attract links), to deep link ratio (the percentage of links that go to your subpages versus just your home page), to internal link (a link from one page of a site to another page on that site), to unnatural-link warnings (warnings in Google Webmaster Tools), to velocity (a site’s link growth speed).
