Lighthouse CI is free and CI-native, but agency portfolios outgrow DIY scripts fast. Compare build vs buy for PageSpeed monitoring: maintenance, client reporting, and when to layer managed monitoring beside your pipeline.
SaaS product teams need front-end performance monitoring on marketing and app URLs, not only backend APM. Here are the metrics, templates, and URL priorities that matter for trials, activation, and retention.
Core Mobile Vitals is an emerging native-app framework from Embrace and SpeedCurve. Web teams already have Core Web Vitals on mobile browsers. Here is how the two lanes differ and what to monitor today.
FCP and TBT are not Core Web Vitals, but they show early paint time and main-thread blocking in Lighthouse runs. Here is what each measures, how they relate to LCP and INP, and when to add them to monitoring budgets.
A phased onboarding workflow for agencies: align scope before kickoff, configure monitoring in days not weeks, set baselines and budgets, and hand off to a repeatable first-month cadence.
PageVitals combines synthetic Lighthouse runs, CrUX, and first-party RUM with CI/CD hooks; Apogee Watcher focuses on multi-tenant portfolio monitoring, automated page discovery, and CrUX via PSI without site instrumentation. Here is when each fits.
A practical pagespeed monitoring tools comparison for agencies: feature checklist, common automated monitoring tools by job, pricing traps at scale, and when to layer diagnostics, CI, and managed monitoring.
Run a free multi-page PageSpeed scan on any domain at apogeewatcher.com/check with no signup. Watcher subscribers also get shareable domain reports built from scheduled monitoring.
Flat daily schedules waste quota on brochure sites and starve checkout URLs. Here is how agencies set PageSpeed monitoring frequency per site, prioritise pages, and keep coverage honest as the portfolio grows.
Web fonts carry your brand, but full character sets often waste kilobytes on every page view. Font subsetting keeps only the glyphs you need so LCP and First Contentful Paint improve without dropping custom typography.
Reactive monitoring waits for the client email. Proactive monitoring uses scheduled tests, budgets, and alerts that respect attention. Here is how agencies make that shift without drowning in noise.
First half of May: domain reports on monitored sites with one shared web and PDF layout, a simpler site screen in the app, clearer failed test runs, a guided onboarding tour, plus public feature pages and blog month archives.
WordPress sites fail in predictable ways: plugin updates, page builders, and caching layers that hide problems until a client notices. This guide shows what to monitor, which URLs matter, and how to run monitoring without living in PageSpeed Insights.
Admin, Manager, and Viewer roles per organisation: who can change sites and budgets, who can invite colleagues, and how read-only mode works when a subscription lapses.
Google's December 2025 and March 2026 core updates did not change CWV thresholds. Here is what shifted, what stayed the same, and how agencies should respond without panic-fixing the wrong thing.
Two copy-paste worksheets: quantify client revenue upside from faster Core Web Vitals, and your agency's time saved versus monitoring tool cost, so proposals and renewals use numbers, not opinions.
Chrome's Lighthouse now documents an experimental Agentic Browsing category: fractional pass ratios instead of a 0–100 score, plus audits for WebMCP, accessibility for agents, CLS, and llms.txt. Here is what changed and what to track in production.
Tests counted only when PageSpeed returns a performance score, clearer failed runs, richer columns on the leads board, a full-screen lead analysis view, and improvements in our site.
