First of all it is key to use keywords and keyword phrases in all of your headlines and subtitles. However only do this if the keyword actually augments rather than distorts the title of your site. Your best bet is to try to keep the title a complete sentence well at the same time trying to capture the gist by using one or two well-chosen, high ranking keywords. When writing copy try using keywords in the first sentence, last sentence and at least once in each paragraph. This is a rule that many professional SEO copywriters follow in attempt to make their technical writing sound more like "natural language." Both humans and spiders dislike robotic language.
Don't be afraid to bold, underline or italicize your keywords. They also stand out if they are used in bulleted links or if they are included in photo or image captions. This type of treatment can help highlight the words or phrases, not only to the reader, but also for the search engine.
Avoid using focused keyword phrases when a broad term is required. Not every generic phrase that you see is an open call to insert a keyword phrase. Also avoid using the same keyword phrase several times in a paragraph if you can. This is called keyword stuffing.
In conclusion the only sure way to test your keyword optimized search engine friendly copywriting is to post it online and then try searching for it in an engine. If type in the keyword phrase and it turns up, then you have done an excellent job as at SEO copywriting.
