One of the best sources of content ideas are the statistics for your website. If you run your own website, your host should have a statistics package that gives you summary information, or you can look in the raw log files. What you want to find are the search engine referrals–the phrases people typed into the search engine that led them to your site. You want to dig through these search phrases, and find ones that relate to your business. By focusing a blog posting on these phrases, you’ll draw people to that blog post when they search for these terms. Make sure you link to specific products or categories on your site.
If you remember Chad and Bob talking about “search engine optimization”, this is one part of doing that. The idea is to put content on your site or blog that is interesting to potential customers, and that will be found in the search engines, hopefully turning searchers into customers.
