If you’d like to enhance the visitor experience on your blog, provide search-engine-optimization benefits, protect your content, provide information about your visitors, and make it easy for readers to spread your words across the Web, there are WordPress plugins for all of the above.
1. Apture. My favorite plugin. It lets you easily create a multimedia link to keep readers on your blog. An Apture link opens to shows thumbnails linking to photos, slideshows, videos, maps, Wikipedia, news articles, files from your computer, and much, much more.
