Start with the best niche keywords and work you way down the list. Long-tail keywords (3-4 or word phrases) will be eaiser to rank for in the search engines. I sometimes like to include words that add some weight like "guide", so an example would be "RSS Link Wheel Guide". Always place these modifiers at the end. You want the keyword phrases you are targeting at the very beginning. Some SEO experts will suggest you stay away from "stop" words like "the" and "for". Stop words are words that are ignored by the search engines. Another thing I have seen in research is that Google in particular does not like the term "review" in titles. Supposedly this is because of all the fake review sites built by affiliate marketers.
I like to work my way through my keyword list, using the best keyword phrases for the URLs first, then the next tier for titles, subheads, categories, tags, etc. Look around this blog and you will get the idea. Here are some of the names and titles for a few of the sites in this link wheel:
