I haven't done a lot of looking around the net but what little I have hasn't produced much in the way of hope for what I'm looking for.

Specifically, I'd love to have a block, module, addon, hack, etc., for my sites that allows me to check keyword density per page onsite.

Something similar to this as mentioned above would be great:

nukeSEO has keyword density, and although by default it checks your main index page, you can override it to check any page on your site (or any other site, for that matter). Have you tried it?

Not yet but it loox like I will be, thanks

Let us know if you have suggestions - SEO is always changing and new tools and approaches are being developed. Our goal is to bring the best tools and approaches to PHP-Nuke.

Would love to see a feature to make all pages have the .html extenstion instead of .php. Ive seen alot of other SEO distribs that have that and some other sites have it aswell. I think its a great idea and would to see if this could happen..

Example:
http://www.nukemods.com/forums.php < shows as php but if u click any forum topic it shows as a .html extension instead of php.

It would really be nice to see this added not just for the forums but aswell as the whole site!

Thats easy enough.
Check out the ShortURL module at www.montegoscripts.com

wow very nice and such a quick response! ty guys.. only have one question though? has this been tested on nuke evolution or can it be ported to nuke evo, or doesnt it matter?

It should. If you run into troubles, just post your issue in my forum where you got ShortLinks and I'll help you through it.

If you are a coder and have some experience with nuke, it will be a piece of cake.
