Tool to extract keywords from a site

Heu guys,

I've some blogs that I'm SEO'ing. The problem is that it is very time consuming to get the keywords for every blog page on my site.

So I'm looking for a tool that can make the link keyword for me.

Lets say I've this blog post: myblog.com/this-is-a-random-post.php
The tool would make something like: myblog.com/this-is-a-random-post.php {This is a random post|A random post| Just a regular post|And so on...|And on...}

Any one knows where I can get a tool to do this for me?

Thanks in advance.

what is pattern in the link?

give me some examples. I can do it in 15 min. Very easy .. just for 10 dollars

Sorry m8, I'm looking for an already built and available software to do my tasks

This is almost what I'm looking for:

It does what I need, but I'm looking for one where I can input a big list of urls (from a txt or text box, it doesn't matter) and it would output something like link-i-inserted.com/random-post.php {this are keywords| I found this keywords|etc|etc} for every link I inserted.
