Asking for competition search tool

[pai_sandee]

i would like to know if there is a tool that can look lots of competition search in the same time. For example, if i have 500 keywords to propose my clients to select 5 of them. Now i use manual like go to google.com and type "book cheap hotel" click search and look for the competition in the natural search and then change keyword like "book cheap resort" and click search and look for the competition in the natural search again and again until 500 keywords.
it's too much!! do you have any tool that can check the number of competion search from google.com with 500 keywords in one time.

Doing it manually is the best way to know your competition sites. Then compare them using seo elite.
