<ul>
	<li><strong>What it does:</strong> Slug Optimizer removes common words from the portion of a post&#8217;s or Page&#8217;s URL that is based on its title. (This portion is also known as the &#8220;slug.&#8221;)</li>
	<li><strong>Why it helps:</strong> Slug Optimizer increases keyword potency because there are fewer words in your URLs competing for relevance.</li>
	<li><strong>How to use it:</strong> Slug Optimizer works without any action required on your part. When you add a new post in your WordPress admin and specify a title for it, WordPress will generate a slug and the new post&#8217;s future URL will appear below the title box. While WordPress is generating the slug, Slug Optimizer takes common words out of it. You can use the textbox on Slug Optimizer&#8217;s admin page to specify which common words are removed.</li>

<ul>
	<li><strong>What&#8217;s a slug?</strong><br />The slug of a post or page is the portion of its URL that is based on its title. When you edit a post or Page in WordPress, the slug is the yellow-highlighted portion of the Permalink beneath the Title textbox.</li>
	<li><strong>Does the Slug Optimizer change my existing URLs?</strong><br />No. Slug Optimizer will not relocate your content by changing existing URLs. Slug Optimizer only takes effect on new posts and pages.</li>
	<li>
		<p><strong>How do I see Slug Optimizer in action?</strong><br />Follow these steps:</p>
		<ol>
			<li>Create a new post/Page in WordPress.</li>
			<li>Type in a title containing some common and uncommon words.</li>
			<li>Click outside the Title box. WordPress will insert a URL labeled &#8220;Permalink&#8221; below the Title textbox. The Slug Optimizer will have removed the common words from the URL.</li>
		</ol>
	</li>
	<li><strong>What if I want to include a common word in my slug?</strong><br />When editing the post or page in question, just click the &#8220;Edit&#8221; button next to the permalink and change the slug as desired. The Slug Optimizer won&#8217;t remove words from a manually-edited slug.</li>
	<li><strong>If I edit the optimized slug but then change my mind, how do I revert back to the optimized slug?</strong><br />When editing the post or page in question, just click the &#8220;Edit&#8221; button next to the permalink; a &#8220;Save&#8221; button will appear in its place. Next erase the contents of the textbox, and then click the aforementioned &#8220;Save&#8221; button.</li>

<ul>
	<li><strong>Why didn&#8217;t the Slug Optimizer remove common words from my slug?</strong><br />It&#8217;s possible that every word in your post title is in the list of words to remove. In this case, Slug Optimizer doesn&#8217;t remove the words, because if it did, you&#8217;d end up with a blank slug.</li>
