If you’re using WordPress and call your post something like “what can you do immediately for higher rankings”, WordPress will give it the URL:
http://www.example.com/what-you-can-do-immediately-for-higher-rankings (replace example.com with your domain name)
Once you install and activate the SEO Slugs plugin, it will remove all of the common words from the URL, such as “a”, “the”, “you” etc). In this example, you’d end up with:
http://www.example.com/immediately-higher-rankings which is a lot more SEO friendly!
