VS Meta Description

it's really foolish to stick a single meta description in the sitewide header template. that's duplicate content so google knows immediately it's poor quality. it will do more harm than good to your rankings.

1 description duplicated sitewide = bad seo

Simple plugin doing exactly what it is supposed to without bloat. 
Maybe a button could be added to the Default Open Graph Image field, to select the image directly from the library instead of pasting its URL.

Works perfectly

The plugin works perfectly, it is extremely small (8kb zipped), which is a big plus, and the developer is super nice, very responsive and simply awesome.

Thanks a million,
Nick.

A 5 star plugin

Meta Tags Generator

It assumes that the theme's screenshot is in .png format. For smaller file size reason, I prefer using .jpg images for my theme's screenshots.

To set the record straight, .png is the preferred format, although other image formats are allowed. This is a direct quote from the Codex pages:

"Note that optionally, .jpg, .jpeg, and .gif are also valid extensions and file formats for the screenshot (though not recommended)." 

Other than that, this plugin is refreshingly small in size, and that's a good thing.

Almost there!
