It is important to realize that picking the right key words is crucial to your SEO success. Always remember that for search engine optimization, your end goal is to rank high in the search engines for key words most relevant and valuable to your web site. For example, if you run a pet dog business, you naturally want to rank high for key words such as 'pet dogs', 'dogs for sale', 'pet dogs for sale'. Better yet, you can narrow down the key words to target very specific niches such as 'chihuahua pet dogs, pet dogs for sale in Brooklyn' etc.
