The goal of this issue is to make it easy to find plugins in the Marketplace with a search engine.

Ideas to improve SEO of http://plugins.piwik.org:

• set a good <title> to each page eg. "WebsiteGroups plugin - Marketplace - Piwik analytics platform"
• set a <description> field to the short description of the plugin
• add following graph meta:

<meta property='og:title' content='PLUGIN NAME' />
<meta property='og:description' content='SHORT PLUGIN DESC' />
<meta property='og:site_name' content='Piwik.org' />
<meta property='og:type' content='website' />
<meta property='og:image' content='URL SCREENSHOT if any was set in plugin' />

• others maybe?
