The SEO Slugs 4 bbPress plugin removes common words like ‘a’, ‘the’, ‘in’ from post slugs to improve search engine optimization.
For example, when you publish a post with a title like this:
“What You Can Do Immediately For Higher Rankings”,
WordPress automatically assigns a long filename to your post, called a post slug:
/what-you-can-do-immediately-for-higher-rankings
SEO Slugs 4 bbPress plugin strips common words like “what”, “you” or “can” out of your post slug to make it more search engine friendly. With SEO Slugs plugin activated, the slug for our example blog post would look like this:
/immediately-higher-rankings
The slug is generated on saving a post (so you get a chance to look at it before publishing, and change it), or on publish. It won’t overwrite an existing slug. You can force a new slug generation by deleting the existing one.

For a better SEO, it is said that the URLs must give information about the content of the web page. Because of this most people uses pretty URLs in wordpress with the permalink options. But the post slug in the URL is generated from the title of the post, and some times this slug is too long because we don’t remove the stopwords, common words without an important meaning, that don’t add anything significant to the URL.
This plugin removes the stopwords from the URLs for better SEO optimization of your blog and for making better and smaller URLs. You can set the stopwords through the `Plugins’ menu in WordPress wp-admin.
For example:
<ul>
<li>You have set the next stopwords: a, an, the, i, you, he, she, we, they, of</li>
<li>You write a post called: Review of the Google Chrome Browser</li>
<li>The normal post slug would be: review-of-the-google-chrome-browser</li>
<li>But the optimized slug is: review-google-chrome-browser</li>
</ul>
All configuration is done through wp-admin. No code editing is necessary.
