GTmetrix for WordPress lets administrators run site analyses, schedule reports, and receive status alerts from the WordPress administration area. Analysis requests use the GTmetrix API. GTmetrix PRO is the option for purchasing additional API credits when the available credits do not cover planned analyses.

Prepare API access

An API account is required to connect the add-on. The plugin listing says account registration is free. Additional API credits can be purchased under the GTmetrix PRO tab when more analysis capacity is needed.

Run and schedule analyses

Run an analysis when you need a report, or schedule reports to run daily, weekly, or monthly. The plugin can send alerts when the site falls below certain criteria, giving administrators a reason to review its status and related GTmetrix information.

Install and connect the plugin

1. Upload the gtmetrix-for-wordpress directory to /wp-content/plugins/.
2. Activate the plugin from the Plugins menu in WordPress.
3. Open the new GTmetrix menu entry and enter your API details.

After connecting the account, run an analysis and pick a report schedule that fits how often you want to review the site.

Manage role access

Only administrators can use the plugin by default. It makes the access_gtmetrix capability. An administrator can assign that capability to other roles with a role-management plugin such as Members or User Role Editor.
