Search Engine Optimization is a Necessity
You must basically write your website using a marketing strategy geared toward your clients. Your language should be clear of jargon and speaks to the public using words they would use when referring to your industry.
How do you do this? You check to see what words people are using in their search engines to find business like yours. For example catalogue verses Catalog, Cell phones verses smart phones. Don't write a website in English for Spanish speaking people. The language you use should be geared toward the majority of the people you want to use your website.
Putting up a website with great content alone is not enough. Websites with great content must be marketed to be found. To make a website popular it must be maintained and marketed with a great strategy. This can take a full time job of talented and creative marketers.
With the constantly shifting rules and regulations, for those who want to remain competitive on the internet it is important to get help and advice from a professional to keep your website's ranking.
