LuckyWP

The “LuckyWP Wiki Linking” plugin allows to easily organize a linking in the wiki style on the website: you specify the keyword phrases for a post, and the plugin places links to this post on other website pages that have the keyword phrases are present in the text.

You DON’T NEED to manually place each individual link, the plugin will make it for you.
When placing a link in a post, whole words are only taken into account. For example, the link with the keyword phrase bus will be added to the text:
<blockquote>
She got on the bus at Clark Street.
</blockquote>
… and the link will NOT be added to the text:
<blockquote>
I’m here on business.
</blockquote>
In addition to links to the posts of the website, you can also place custom external links by specifying them when adding a keyword phrase.
<h4>The typical use cases:</h4>
<ul>
<li>When creating/changing a post we add a keyword phrase to it.</li>
<li>We click on the “Bind to posts” button next to the keyword phrase.</li>
<li>Profit! Links to the post are already available on other website pages.</li>
</ul>
In the <a href="https://theluckywp.com/product/wiki-linking/" rel="nofollow ugc">premium version</a> the second step can be skipped — links will automatically be created!
<h4>Features</h4>
<ul>
<li>Up to 30 keyword phrases for the entire website (In the <a href="https://theluckywp.com/product/wiki-linking/" rel="nofollow ugc">premium version</a> the number of keyword phrases is unlimited) and unlimited number of links to them.</li>
<li>The links is displayed ONLY on the single page of a post, in all other places (RSS feed, the editor on the control panel and etc.) this link will NOT be displayed.</li>
<li>Placing of links in the posts and the pages.</li>
<li>Placing of links in custom post types.</li>
<li>Support of links to third-party websites for keyword phrases.</li>

Do you link to the iTunes Store with or without an affiliate program? this plugins for you!
The plugin adds an itunes button to the visual editor which when clicked bring forward a jquery 
dialog containing a search for the iTunes store link maker.
After searching, clicking on any link will ask for a title for the link and insert it into the 
content editor. iTALM also enables the ability to directly link to albums, something the 
standard link generator does not normally do.
iTALM also keeps track of recently clicked links and offers them up for clicking prior to 
searching, while also offering a link masking to hide your affiliate junk from captain smarty pants.
As of 0.5.3 it now supports search on entities, What does this mean for you? 
* searching for iPhone/iPad apps individually and for software developers 
* searching specifically by artist/album/track name 
* search for movies by artists/studio 
* columns change based on the entity being searched for
As of 0.6 we now ONLY support using the PHG affiliate, which everything seems to be moving to.
<h3>Upgrading</h3>
If you’ve come from a previous version of iTALM and you’re not doing a fresh install, there’s a chance you’ve 
done some monkey patching to side step previous installation issues. For example, some of you modified the ita-version variable, 
this is used to detect upgradability, if you’re using 0.5.2 please set it to 0.1 before proceeding with the upgrade. On this, future 
versions from (0.5.3 forward) will set this to the current version number, it was supposed to just be a database version number, but 
all these different version numbers are obviously confusing people (me included), so from now on everything to do with iTALM will carry 
the version number of the plugin it came from (this includes the plugin for tinyMCE support).

iTunes Affiliate Link Maker (iTALM)

The plugin will add a button to the visual editor to run the iTunes Link Generator and offers link masking to hide your affiliate junk.
