We'll create fresh WordPress site with Hide My Dates installed. You have 20 minutes to test the plugin after that site we'll be deleted.
The plugin uses a CSS hack to show the date – your visitors see it, but Google takes it for the “title” parameter of a “span” element and does not consider it to be a part of the page content. Therefore, the publishing date is not shown in the search snippet.
The plugin works with ALL themes now (from version 2.00).
If you liked my plugin, please rate it.
