Introducing WordPress Author Bio Box plugins — free and paid — to display author info, article info, and popular posts below blog posts. Either plugin automatically pulls the respective author’s name, photo, biographical info, social networking links and article meta data such as categories, tagged keywords, last updated date, etc.
The premium version of the plugin automatically shows, by default, the 6 most recent posts published by the author. However, to get the most SEO value out of this internal linking feature, the premium version allows you to manually select up to 20 articles.
Pro Tip: Identify your posts with the highest search and traffic volume (Google Search Console Impressions and Clicks), and select those to strengthen internal PageRank of these posts and improve organic rankings.
