Discovered a tool that does a good job of showing related keywords that you should be using in your content. It divides the keywords into colored groups, and advises that you should be using words from each color to round out your theme. The tool isn't free, but you can purchase a one day use for only $7.00. I plugged in all my main keywords during my one day use, and was given the option to save each report in excel format. The amount of data is really astounding and was well worth the $7 I paid for it. You can also run a free demo using a keyword phrase they supply to see what the report looks like. With themes being the buzz phrase in SEO these days, this tool could be a useful addition to your SEO repetoire. Check it out at http://188.8.131.52/Theme-Master/index.html.
