In 2005 Google Introduced Matched content to help publishers promote their website content to their visitors. AdSense Matched content is actually a content recommendation tool that shows related posts to your readers. It generates contextually relevant article recommendations from the pages on your blog by displaying thumbnails. In other words it helps your blog visitors to discover relevant articles on your blog. It is a Google version of the Related Posts Widget that we use in blogspot and wordpress blogs.
By setting up matched content on our blogspot blog, we did not only helped our readers to discover related content on our site but we also succeeded in generating more pageviews, lower bounce rate and some extra ad impressions thanks to its native ads option.
