<p>SEO Tool which replace titles on selected pages and posts. Also adds ability for meta description.</p>
<h3>Important note</h3>
<p>This plugin uses “Session Buffering” to work with some websites (for forcing replacement of titles). This means that if your host / web server uses a cache service there is a possibility that a conflict might occur. We give no support regarding host / web server support to avoid this.</p>
<h3>Planned changes</h3>
<p>In the future we plan to change the backend overview and settings page so it will use WP Table structure instead for better handling.</p>
