Some PHP programmers dream of or even try to create an own content management system, targeting the same. Why want they do it? I guess, such creations would include all the best practice examples into it, then they would get rid of all existing bugs and misbehaviors, then they would systematize and list all current knowledge in the creation.

With the HASCH OnPage SEO framework i target to systematize the OnPage SEO knowledge and to get rid of unvalidated parts of it.

Then lets get down to the nitty-gritty:
