SEO implement?

[eluser]pickupman[/eluser]
Taking the idea from Phil Sturgeon's PyroCMS and similar feature in Wordpress, is create a slug field. When I create a new article, I have the slug auto generated from the title of the post. I check the DB if slug already exists when saving the page. Then I use the route

Code:

$routes['blog/(:any)'] = 'blog/view/$1';

Then in my blog/post method I first lookup the slug parameter in the DB, and if nothing is returned I check for a post id. If that fails, I just load the default "home" slug.
