Before we installed the SEO Slugs for WordPress Plug-in the URL created by this post title looked like this:
http://www.wordpressseo.ca/blog/an-example-of-how-the-seo-slug-plugin-can-help-your-posts/
If you look at that URL you will see that this URL is pretty long and although it is readable it could be far more concise.
With the SEO Slug plugin installed the slug is radically more concise:
http://www.wordpressseo.ca/blog/seo-slug-plugin-posts/
Perhaps, however, you want to makea change to the slug… will it hold? Yes! As soon as you make any edit to the slug the SEO Slug Plugin will no longer intervene. If you wish to go back to letting SEO Slug handle your URL slug then just edit the slug and delete what you have there and save. Voila! The plugin will take over once more.
