Once you receive your results, simply check the boxes to add the words and phrases you'd like to build tags around. Hit the button, and no longer do you have to write your own META code. The site also contains other helpful keyword tools to help you further your optimization goals.
This keyword calculator works in a different way, by analyzing words instead of Web pages. This actually helps you tailor your content to the most popular words and search terms of the day, increasing your chances with search engines to help you boost traffic.
