What it does
Checking the speed and accessibility of one site is easy. Checking dozens by hand, one URL at a time, gets tedious fast. This extension moves that work into the MainWP Dashboard you already use to manage client sites. It sends audit requests through the Google PageSpeed Insights API and gathers performance, accessibility and SEO scores for each child site on a single page, so you can compare sites side by side and spot the ones that need attention.
Audits can run in bulk across many sites at once or on a daily, weekly or monthly schedule, so monitoring keeps going without manual checks. You can set thresholds and receive alerts when a site falls below them. Findings can be turned into detailed reports for clients, and developers can trigger audits and pull results through WP CLI or the MainWP REST API. It requires the MainWP Dashboard plugin to work.
Best for
- Agencies managing many client WordPress sites
- Freelancers who report site performance to clients
- Developers automating audits with WP CLI or REST API
Features
PageSpeed Insights audits
Runs audits through the Google PageSpeed Insights API to measure performance, accessibility and SEO metrics for each connected child site.
One page of results
Collects Lighthouse statistics for all your child sites on a single dashboard page, making it simple to compare scores and review problem sites.
Scheduled audits
Set audits to run automatically on a daily, weekly or monthly schedule so your sites are checked regularly without starting each test by hand.
Bulk auditing
Audit many sites at the same time instead of one by one. The developer's example cites testing 30 sites in 5 minutes rather than 16.
Client-ready reports
Generate detailed, customizable reports that lay out audit findings and improvement suggestions, useful for sharing progress with clients and stakeholders.
Threshold alerts
Get notified when a site's performance score drops below a threshold you define, so you can look into issues early.
WP CLI and REST API
Start audits and fetch results programmatically with WP CLI or the MainWP REST API, which suits scripted workflows and custom integrations.
Works across dashboards
Use the extension on an unlimited number of MainWP Dashboards, which helps if you run separate dashboards for different clients or teams.
