What is Author Box plugin?
Author box plugins add a biographical section to the end of WordPress posts, displaying information about the post author. A typical author box includes the author photo, name, short bio, and links to social media profiles or personal websites. Some themes include author boxes natively; when a theme does not, an author box plugin fills the gap.
Author boxes serve both a user experience purpose — giving readers context about who wrote the content — and an SEO purpose. Google’s E-E-A-T guidelines (Experience, Expertise, Authoritativeness, Trustworthiness) place weight on clear authorship signals, particularly for health, finance, legal, and other YMYL (Your Money or Your Life) content. A well-configured author box with a complete bio, credentials, and verifiable author information supports these signals.
Author bio information is typically stored in the WordPress user profile. Author box plugins pull from the user profile bio and avatar, optionally supplemented by custom meta fields for social links and additional credentials.

Pros & Cons
Pros

- Some themes include author boxes natively making a plugin unnecessary
Free vs Premium
Free author box plugins cover the core display — name, avatar, bio, and basic social links. Paid options add more display customisation, multiple author box styles, custom field support for credentials and titles, conditional display rules, and widget placement options. For most sites, a free plugin is sufficient if the author profile data is well-maintained.
Common Problems & Fixes
The author box is not showing on my posts.
Author box plugins typically hook into the the_content filter to append the box after post content. Some themes or page builders that modify content output can prevent this hook from firing. Try using the shortcode if the plugin provides one, placing it manually in a post template. Also verify the post type is in the list of supported post types in the plugin settings — some plugins only show on standard Posts, not on custom post types by default.
The author bio is empty in the author box even though I filled it in.
Author box plugins pull the bio from the WordPress user profile Biographical Info field, located under Users, then your Profile, then the Biographical Info textarea. Ensure this field is filled in and saved. If you use a plugin like Co-Authors Plus with guest authors, the bio may be stored in a different location — check the guest author profile rather than the WordPress user profile.
Author box social links are not appearing even though I entered them.
Social link fields in author box plugins are typically stored as user meta, either in the WordPress user profile (which has limited built-in social fields) or in custom fields added by the author box plugin itself. Check whether the plugin uses its own social link fields in the user profile or relies on WordPress built-in fields. The standard WordPress profile only includes a website field — social network URLs require either a plugin that adds custom fields or a profile plugin like PublishPress Authors.
Customization & Developer Notes
How do I add schema markup for the author to support E-E-A-T?
Most quality author box plugins include Person schema markup output that describes the author as a structured data entity. Enable schema output in the plugin settings if it is not on by default. The schema should include the author name, image, URL, and description at minimum. Verify the output using Google Rich Results Test or Schema Markup Validator. For stronger E-E-A-T, also ensure the author has a dedicated author archive page with their full bio, credentials, and links to verifiable profiles like LinkedIn.
Can I show different author boxes for different post categories?
Basic author box plugins show the same author box on all posts where it is enabled. Some paid plugins include conditional display rules that let you configure different author box styles or content for specific categories, post types, or user roles. If conditional display is not available in your plugin, use a Custom CSS class or a hook-based approach in your child theme to show different content for specific post contexts.
Frequently Asked Questions
Does an author box actually help SEO?
An author box supports E-E-A-T signals, which is a quality framework Google uses when evaluating content rather than a direct ranking factor. For YMYL content — health, finance, legal — clear and credible authorship is particularly important. A complete author box with a real photo, verifiable credentials, and links to established profiles helps Google understand who is behind the content. An empty or generic author box adds little value. The quality of the author information matters more than the presence of the box itself.
Should every WordPress site use an author box?
Not necessarily. Author boxes make most sense on content-driven sites where the author’s identity and credibility are relevant to the reader — blogs, news sites, review sites, and sites publishing advice on important topics. For business sites, service pages, or eCommerce product pages, author boxes add less value and can clutter the layout. Use author boxes where they add genuine reader context, not as a default addition to every site.
How do I set up author boxes for guest contributors who do not have WordPress accounts?
For guest authors without WordPress accounts, use the Co-Authors Plus plugin which supports guest author profiles. Guest author profiles in Co-Authors Plus include name, bio, avatar, and social links without requiring a WordPress login. Pair Co-Authors Plus with an author box plugin that is compatible with it — many are, but check the plugin documentation. Guest author profiles appear in author boxes the same way registered user profiles do.
Can I use an author box on custom post types?
Most author box plugins default to showing only on standard Posts. Look for a setting in the plugin that lists supported post types and add your custom post type to the list. If the plugin does not support custom post types through settings, some plugins allow enabling support by adding the post type through a filter hook in your child theme functions.php.
