100% Free SEO Auto Keyword Generator Tool v8.0.0

the right SEO keywords can help define the success of your website!

SEO is what we do!

Using the right keywords on your website and in your content is absolutely critical to being properly indexed by search engines.

Without the right keywords, your clients and customers will go to your competitor's websites instead. Don't be pushed below the fold in your SERPS. Rise above!

I wrote this tool over a weekend to help you find the best keywords for organic SEO targeting ads. The results are based on the content already on your website.

Many people charge thousands of dollars to "optimize your website", and they use freely-available tools to do it, just like this one. Save your money and do it yourself!

There is no cost at all to use this tool, it is 100% free and easy to use. I am selling nothing to use this.

Feel free to email me with suggestions, bugs or any other questions you might have about SEO or this tool.

SEO is what we do!

Credits for this idea go to Chris Green at WebCreationz UK. Chris has written a very useful tool that I've successfully used for a few years to help extract the most-frequent keywords from my pages.

I decided to improve upon Chris' work and added some new features. This version includes the ability to use pasted input.

Have fun!
