What freelance writers need to be concerned with is keywords. What are keywords? Keywords are the words and phrases that web surfers type in when they search for things online. For example, let's say you were interested in starting a foreclosure cleanup business. You may not know anything about it other than foreclosures are hot in the news right now and you are interested in starting this kind of company. So, you log onto your favorite search engine, (eg, Google, Yahoo! MSN, etc.) and type in the keywords "foreclosure cleaning business" or "foreclosure cleaning" or "foreclosure cleanup" or some other relevant keyword phrase.
