If you need links, checkout your competitors and see if you can get some of their good ones.
Links are an essential part of a productive SEO campaign. It can be hard to find good ones, though. Why not look and see if your competitor has some good links- and see if you can get them too.
Some of these links might bring in some traffic. That’s great, but it’s also gravy compared to the increased search engine traffic you’ll get from the boost from ranking better, thanks to these links.
Of course, just because your competitor has a link from somewhere, doesn’t mean you would want that site to link to yours. You need to evaluate the opportunity to see if this is a kind of link you’d want, before you try to get one, too. Some links can be bad, and actually hurt your SEO efforts. The key is knowing the difference.
