Overview

Checking site quality one site at a time takes a lot of effort when you look after many WordPress installs. This extension connects to the MainWP Dashboard and uses the Google PageSpeed Insights API to audit your Child Sites from one place. Lighthouse statistics for performance, accessibility and SEO are collected on one page, which makes it easier to spot the sites that need attention first.

You can run audits in bulk, or set them to repeat daily, weekly or monthly so monitoring continues without manual work. Reports present the findings and improvement suggestions in a form you can share with clients. Alerts tell you when a site drops below thresholds you define. Developers can also run audits and fetch results through WP CLI and the MainWP REST API, which fits custom workflows.

Features

  • Google PageSpeed Insights audits: Audits use the Google PageSpeed Insights API to measure performance, accessibility and SEO metrics, giving you a clear read on each site's health and user experience.
  • Central dashboard view: Monitor and audit multiple Child Sites from your MainWP Dashboard, with all Lighthouse statistics placed on one page for quick comparison and review.
  • Scheduled audits: Set audits to run daily, weekly or monthly so your sites are checked continuously without anyone starting each test by hand.
  • Bulk auditing: Run audits on many websites at the same time instead of testing each one individually, which cuts the time spent on manual checks.
  • Customizable detailed reports: Generate client-ready reports that present audit findings and suggested improvements clearly, which helps when you explain results to stakeholders.
  • WP CLI and REST API support: Run audits and fetch results programmatically through WP CLI and the MainWP REST API, so audits can fit into your own automated workflows.
  • Threshold alerts: Receive notifications when a site's performance falls below the thresholds you set, so you can look into problems before they affect visitors.
  • Use across many dashboards: The extension can be used across an unlimited number of MainWP Dashboards, which suits people who oversee several installations.

Best for

  • Freelancers who send audit reports to clients
  • Developers automating checks with WP CLI or REST API
