Your choice of keywords greatly influences the outcome of a search. That's why you must choose words that will help the engine find the desired target sites.
How do you choose keywords?
* Write exactly what you're looking for - the exact word or phrase you're looking for might be out there, waiting for you.
* Use words or phrases that are likely to appear in the sites you want to find.
* Avoid using words that are likely to appear in other sites as well.
