Actually, its quite simple if you know how.
Go here: www.webmaster-toolkit.com/keyword-analysis-tool.shtml
This is a keyword analyzer. You simply drop your URL in the box and click "analyze keywords". This tool will report back to you the total number of unique words it found on your page, how many times each word repeated, and a percentage of what that word makes up with respect to the overall page. It is the percentage you should be concerned with. Sites competing for SERP should have their keyword(s), search phrases up to at least 3%. The higher the better. For competitive keyword(s), phrases, it is not unusual to see 10% and higher.
There are other keyword analyzers on the web that will check a whole search phrase at one time, but I prefer a tool that checks each word individually. The engines will weigh each word individually, so if I am competing for a phrase (more than one word, or keyword) I like to see how each word in it rates. After all, the optimization score for keyword(s), search phrases, is only the sum of its parts, so I sleep better knowing each and every word in a phrase is maximized, so the overall total percentage is as high as I can get it, and it is not depending on any single word for its strength. This tool will tell you that.
