The main purpose of this plugin is easy link building.
For example, you can create a page or post with detail description of some term. Most likely, this term is used in other posts and it would be appropriate to put a links from that posts to you page. But doing this operation manually is very time consuming task.
This WordPress plugin allow you to maintain a list of terms and assign links to them. Plugin automatically replaces terms occurrences in posts with appropriate links. You can control the number of terms replacements.
This plugin allows.
<ul>
<li>Create, update and delete terms through admin interface (Terms menu). Each term can contain one or several word forms (e.g. pear, pears).</li>
<li>Assign a link to a term. This link can point to your blog post, page, custom post type or to a page on another site.</li>
<li>Control how many terms will be converted to links in each post.</li>
<li>Select where you want to replace terms, in posts content, in posts comments or both.</li>
<li>Set several word forms for each term. For example, “apple|apples”. Word forms should be separated with a “|” symbol.</li>
<li>Search for terms in posts content and convert them to appropriate links. This task is performed automatically when plugin is activated.</li>
<li>Disable terms to links conversion for individual posts.</li>
<li>Wrap links with arbitrary text (for example, you can wrap link with strong tag)</li>
<li>Export and import terms and plugin options.</li>
<li>Export terms in CSV format.</li>
<li>Packet terms creation.</li>
<li>Permalinks update function (use it after permalinks structure updates).</li>
</ul>
Please, note that terms will not be replaced with links in following cases.
<ul>
<li>If the term is already inside the link. E.g. if the link was created manually. So the plugin will not change any links that already exists in the post.</li>
<li>If the term is located inside html tag. For example, inside <code>alt</code> attribute of <code>img</code> tag.</li>
<li>If the term is located in <code>h1</code>–<code>h6</code> tags.</li>
<li>If the term is part of another word. E.g. term = <code>car</code> and the word is <code>carrot</code>.</li>
<li>If you checked “Disable Terms Descriptions plugin for this post” checkbox (at the bottom of post edit screen).</li>
</ul>
Important!
Huge terms lists with hundreds of terms can increase page creation time. In such cases, consider to use caching plugin.
