Tools to understand which keywords are found on a web page

It may seem strange to you, but sometimes understanding what the keywords of another website are is not easy. Some tools can help, but don’t think they are precise or really useful. They will only give you a vague idea. Your brain will always work better, only you will have to spend time reading the page content and making a list. Anyway here they are:

• Open Site Explorer

• Google AdWords Keyword Tool

• Sem Rush

• Alexa

Good luck!
