This plugin lets you laser focus your banners, advertisements, promos and affiliate promos in relevant posts that you choose. When you put out a quality review or are talking about a specific product, people are more open and ready to checking out the product when you invite them to. Take it a step further. Make your call to action bolder or place a banner ad directly in that post instead of showing other ads that may not be relevant.
Features
<ul>
<li>Use HTML or Javascript ads</li>
<li>Includes the option to fall back to a default advertisement if no ads are found for that post (optional)</li>
<li>Automatically place ads before, after content or using widgets</li>
<li>For finer control, you can choose to use a shortcode to include the ad directly into your post</li>
</ul>

Author Box Plus is a lot more than just an Author box. If you have a blog and are dealing with multiple authors on your blog, this plugin will add some exciting features for you. 
It will let you enable or disable an author from putting a link back on their names. The admin will be able to enable a link to the authors so they can have their own page on your domain (http://yourdomain.com/author/user-name).
When you enable the link for the authors, it will be linked to their personal author page like above. Authors can then design their own page with the default template and have their Bio, social media profiles and recent posts displayed on this page. 
This will be in addition to the author box which displays underneath each post.
Features:
<ul>
<li>Displays Author’s Bio along with social icons, linked to authors social accounts at the end of every post.</li>
<li>Author’s Profile Page: Complete detailed profile page, with profile picture, author bio, author recent blog posts, author social profile details.</li>
<li>Administrator can decide which author’s profile page should be visible to visitors.</li>
</ul>
