This plugin allows you to create internal <code><a></code> links within your content that will not break when things get renamed or moved. While there are similar plugins available, they do not offer important SEO options.
You can add any HTML attribute to your link as long as it’s prefixed with “attr_”. And because it supports attributes that may not currently exist, it is future proof.
Examples:
<ol>
<li>Link to a post/page by ID or slug
<ul>
<li>Shortcode: <code>[link id="1234"/]</code></li>
<li>Shortcode: <code>[link slug="post-slug"/]</code></li>
<li>Output: <code><a href="http://domain.com/post-slug/">Post Title</a></code></li>
</ul>
</li>
<li>Link to a category by slug
<ul>
<li>Shortcode: <code>[link cat="cat-slug"/]</code></li>
<li>Output: <code><a href="http://domain.com/cat-slug/">Category Name</a></code></li>
</ul>
</li>
<li>Link to a tag by slug
<ul>
<li>Shortcode: <code>[link tag="tag-slug"/]</code></li>
<li>Output: <code><a href="http://domain.com/tag-slug/">Tag Name</a></code></li>
</ul>
</li>
<li>Custom text instead of retrieved title
<ul>
<li>Shortcode: <code>[link id="1234"]custom text[/link]</code></li>
<li>Output: <code><a href="http://domain.com/post-slug/">custom text</a></code></li>
</ul>
</li>
<li>Additional attributes for SEO/other
<ul>
<li>Shortcode: <code>[link id="1234" attr_rel="something" attr_itemprop="specialty"/]</code></li>
<li>Output: <code><a href="http://domain.com/post-slug/" rel="something" itemprop="specialty">Post Title</a></code></li>
</ul>
</li>
</ol>

Important Notice:
Gravity Forms v.1.9 introduced HTML5 Placeholders and field label visiblity features. As of v.1.9.1 field label visibility feature is hidden by default and can be enabled using:
**add_filter( ‘gform_enable_field_label_visibility_settings’, ‘__return_true’ ); **
This plugin is NOT compatible and will not be supported with Gravity Forms 1.9 and above.
The plugin extends the default Gravity Forms form editor to support native HTML5 placeholders and label management.
It allows you to define placeholders for a wide variety of build-in fields and to customize field labels & sublabels by either overriding the default with your own and/or allowing you to hide them individually.
Javascript fallback is used for old browsers that don’t support the HTML5 placeholder attribute.
It is fully compatible with WPML for placeholder and label translation using the Gravity Forms Multilingual plugin.
