Hey, I just noticed this you NEED to change your permalink structure.
Go to your dashboard > settings > permalinks
Select the custom radio button
enter this in the field
/%category%/%postname%/
Then create (or edit if it exsits) a file called .htaccess in your document root
Lastly write to the file
<IfModule mod_rewrite.c>
RewriteEngine On
RewriteBase /
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule . /index.php [L]
</IfModule>
And there you have it, a much search engine friendlier url structure.
Your permalinks (url to individual posts and cats) will be
www.mmasite.info/category/post-title
Use this to target your longtails. ie, if you had a local dojo paying you for leads you could drop some cool stuff in your url like
www.mmasite.info/cityname/sign-up-for-karate-classes-in-cityname
This is just an example but I think you will follow what I'm dropping here.
Use something like the google keyword tool, or even a paid research tool to find what your intended audience is searching for.
