When search engines index your website they look for keywords that are in abundance on your website. They match those keywords up with keywords mentioned in other websites such as directories and blogs. When those other directories and blogs point those particular keywords like “Web Design” to your website, it gives a lot more weightage. The more relevant keywords link to your website, the higher your website ranking gets for those keywords.
A website called Open Site Explorer assists you to do just that. It allows you to search for links pointing to your competitors website. If your competitor is listed on a particular directory or blog, chances are you can submit to your website to that directory or blog too (usually for free). This means you will get higher number of inbound links which come from relevant keywords for your business website. Try this technique today and let us know what you think of it.
