Each page must have its own unique Title. An empty or duplicate Title will not be accepted. The positioning of the words is very important. The main keyword should be placed among the first words. Do not write page titles that are too long — the maximum is 70 characters and 12 words. Avoid listing keywords or your site will be penalized by search engines. Write the name of the company, but don't put it at the beginning.
