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>

You can bring on the first page or any other page, for the new visitors, the old content.It’s no need of the question why should I do this because you want that your visitors could have in their view your older articles.
What does this plugin bring new?
Other plug-ins are already doing a great job about random posts, but for me was not important to show just a list of a few links to my articles; not just a random generated list, with some titles. For some new visitors, the article’s content is more important than the title, actually, for anybody this statement is true . 
So, I created this plugin to mark out even some text from the random article.
