Here’s a practice that’s as old as search itself. Ask the search engines to show you who is linking to your site. Then, ask who is linking to your competitors’ sites. Compare the list of those linking to you against those who aren’t.
You want to make tracks to those who aren’t linking to you and make nice-nice, somehow. Maybe you can just ask them for a link, and they’ll give you one. Maybe not. Having good content to link to can help your inbound link campaign. The more quality sites that point to you, the higher you should appear in search engine results. LC
