‘Embed Link ShortCode’ tries to emulate the functionality that facebook has when a link is pasted to the input status. 
But it doesn’t happen when you paste a link in the body of a new post (as when you paste a youtube link in the visual view of a post), it’s done using a shortcode. 
The provided link to the shortcode is fetched to get the meta tags, and these meta tags are used to render the new post content. It tries to get an image and put it as 
post default thumbnail, and it uses some meta tags to get title text and to add a quote. The order in the post content is: image, quote and link. 
If you don’t like the HTML render, you can always edit the code to change format or suggest me some changes.
Usage:
1- Create a new post.
2- Add only the shortcode with the link (in HTML mode, not Visual) in the post body. For example:
[embedlink]http://example.com/example[/embedlink]
3- Push ‘Save Draft’.
If all is ok, the post content will be rewritten with the rendered html code. An image may be uploaded to the media library and added as post default thumbnail. 
 If nothing happens, click the preview link and some error message may be displayed. If a blank entry is showed, all is ok, then click Edit and you will see the rendered code. 
 Otherwise, it will be a bug: please, report it adding the URL you used and the plugin version (update to last version before report!).
4- Review the generated code.
<h3>Notes</h3>
<ol>
<li>The post format will be set to ‘link’ by default.</li>
<li>The image (if any is found) will be added to the media library and set to post default thumbnail.</li>
<li>The content post is rewritten when you save it.</li>
</ol>

Link Juice Keeper redirects all non-existing URLs, that normally return a 404 error, to the page/post of your choice. This way everyone who comes to your blog via a broken link (both people and robots) will be redirected to a valid page.
A 404 Error (Page not Found) is very common and one of the main reasons Google can give you a lower ranking. Taking steps to handle 404 errors can be complex for non-techy users. With this free plugin you can finally resolve all 404 errors with just 1 click!
<h3>What are 404 errors?</h3>
As you probably know, incoming links play important role in ranking well in Google and other search engines. Therefore you should ensure that every incoming link leads to one of your valid pages on your blog. This may be a challenge because your website is dynamic and it changes every day:
<ul>
<li>you might remove or unpublish posts or pages;</li>
<li>you might change your URL structure on your blog;</li>
<li>links may brake because of technical misconfiguration;</li>
<li>a webmaster might add your link in their posts with a typo;</li>
<li>a visitor may simply mis-type your post’s URL</li>
</ul>
Any of the above will lead to link juice waste and a 404 error. You can avoid this simply by installing this plugin.
<h3>Features</h3>
