Rich snippets (microdata, microformats, RDFa & Data Highlighter) are the few lines which appear underneath every search result. Add structured data in the form of star ratings, review info, music links and event info with this light-weight plugin to your posts, and Google will display your rich snippets when someone searches for a term that features your site.
Get a higher click through rate with attractive and informative rich snippets.**
<h4>Easy Installation</h4>
A few clicks and you are there.
<h4>Customisation</h4>
With customisation options, CSS editing features and convenient dropdown boxes – you are a few steps away from having rich snippets that fit the theme and styling of your site.
<h4>Ongoing Development</h4>
At present, the plugin offers rich snippets for reviews, music and events. However, we are working on the development of this plugin to include all other forms of rich snippets.

This is a WordPress plugin that allows you to use the Smart App Banners with your 
WordPress blog.
<a href="https://developer.apple.com/library/ios/#documentation/AppleApplications/Reference/SafariWebContent/PromotingAppswithAppBanners/PromotingAppswithAppBanners.html#//apple_ref/doc/uid/TP40002051-CH6-SW1" rel="nofollow ugc">According to Apple</a>, Smart App Banners:
<blockquote>
vastly improve users’ browsing experience compared to other promotional methods. 
 As banners are implemented in iOS 6, they will provide a consistent look and 
 feel across the web that users will come to recognize. Users will trust that tapping the 
 banner will take them to the App Store and not a third-party advertisement. They will 
 appreciate that banners are presented unobtrusively at the top of a webpage, instead of 
 as a full-screen ad interrupting the web content. And with a large and prominent 
 close button, a banner is easy for users to dismiss.
</blockquote>
It’s really simple to use. In short, you download and activate the plugin. On pages and posts you should find a “Smart App Banner” settings box. If you want the Smart App Banner to appear on this page then enter the App ID of your application here. You can also enter affiliate data and an app argument here.
If you want to display a banner on the home page there’s a setting screen (Settings -> Smart App Banner) where you can enter the App ID.
You can find the App ID in iTunes Connect, using the 
<a href="https://itunes.apple.com/linkmaker/" rel="nofollow ugc">iTunes Link Maker</a> or if the iTunes URL for your 
app looks like this:
https://itunes.apple.com/us/app/rootn-tootn-baby-feed-timer/id530589336?ls=1&mt=8
Then your ID is “530589336”.
The other two fields are optional.
The affiliate data field varies depending on the affiliate. The most common is PHG, where the value looks like “at=AFFILIATE_TOKEN” or “at=AFFILIATE_TOKEN&ct=CAMPAIGN” (without the quotes). You can find the token when you sign into the PHG website. The campaign is just some text you use to identify a particular marketing campaign.
So I might have “at=11lmMT&ct=wordpress” on the product pages of my website. Check the documentation to find your affiliate token and confirm the format.
<a href="https://developer.apple.com/library/ios/documentation/AppleApplications/Reference/SafariWebContent/PromotingAppswithAppBanners/PromotingAppswithAppBanners.html" rel="nofollow ugc">According to the documentation</a>, the app argument value is:
<blockquote>
A URL that provides context to your native app. If you include this, and the user has your 
 app installed, she can jump from your website to the corresponding position in your iOS app.
</blockquote>
This plugin does not restrict or validate what you put here.
<blockquote>
You can format it however you’d like, as long as it is a valid URL.
