Google PageSpeed monitoring for every WordPress site you run
VigilDeck runs Google PageSpeed Insights on a schedule for each site and charts the scores over time, so a slow page shows up on a dashboard instead of in a customer complaint.

Why manual PageSpeed checks stop working at scale
Performance is not something you can check once and forget. A plugin update, a new hero image, a third-party script added to the footer, any of these can quietly drop your PageSpeed score, and you usually find out weeks later when rankings slip or a client asks why the site feels sluggish. VigilDeck watches for that. It runs Google PageSpeed Insights against each of your WordPress sites on a schedule and keeps the history, so the number is always current and you can see exactly when it changed.
This is monitoring, not a one-off audit tool. You do not open PageSpeed, paste a URL, wait, and repeat that for forty sites every Monday. VigilDeck does the checking for you across every site in your account, records the results in one place, and charts them so the story over time is obvious. When performance drops, you see the drop and the date it happened.
Running Google PageSpeed Insights by hand is fine for one site. Copy the URL, run the test, read the score. But the moment you are responsible for ten, fifty, or a hundred WordPress sites, the manual approach falls apart. Nobody re-runs every site every week, so scores go stale and regressions go unnoticed until they have already cost you traffic.
A single score at a single moment also tells you almost nothing. Was 62 always the number, or was it 89 last month before someone installed a page builder add-on? Without history you cannot tell the difference between a site that has always been average and a site that just fell off a cliff. The point in time reading hides exactly the change you need to catch.
Then there is the mobile and desktop split. Google evaluates them differently, and a site can look healthy on desktop while struggling badly on mobile, which is the version most of your visitors and most of Google's ranking signals actually use. Checking only one strategy, or averaging them in your head, leaves a real problem invisible.
PageSpeed monitoring built for many sites at once
Every capability is aimed at catching performance changes across your whole portfolio without you lifting a finger.
Scheduled Lighthouse scoring
VigilDeck runs Google PageSpeed Insights, powered by Lighthouse, on a fixed schedule for every connected site. Free plans are checked weekly and paid plans daily, with no per-site button pressing on your side.
Mobile and desktop, separately
Both strategies are scored and stored on their own. A site that passes on desktop but fails on mobile shows both numbers plainly, so the weaker experience is never hidden behind an average.
Core sub-metrics, not just the score
Alongside the headline number VigilDeck records Largest Contentful Paint, Speed Index, Total Blocking Time, and Time to Interactive, so you can see which part of the load is dragging the score down.
Trends over time
Every check is kept and charted. A gradual slide or a sudden drop is obvious at a glance, and you can line the date up against your activity log to find the change that caused it.
Immediate first check
When you add a site, VigilDeck runs a check right away instead of waiting for the next scheduled window. Scores appear as soon as the site is connected, so onboarding a client never leaves you staring at an empty chart.
Every site in one view
Scores from all your sites land on one cross-site dashboard. You compare, sort, and spot the slow ones without opening a single site individually.
How PageSpeed monitoring works
Connect a site
Install the free VigilDeck connector plugin from WordPress.org and link the site to your account. That is the only step needed on the WordPress side.
Get an instant baseline
VigilDeck immediately runs a mobile and desktop PageSpeed check so you have a starting score the moment the site connects, not days later.
Let the schedule run
From then on the checks repeat automatically, weekly on Free and daily on paid plans. Each run records the score and the core sub-metrics.
Watch the trend
Open the dashboard to see current scores across every site and the full history charted, so any regression and the date it started are easy to find.
Why scheduled PageSpeed monitoring is worth it
Protect your search rankings
Page speed is a real ranking factor, especially on mobile. Catching a regression the week it happens, rather than after traffic drops, keeps performance from quietly eroding your SEO.
Protect conversions
Slow pages lose sales and sign-ups. Continuous scoring means a performance problem on a checkout or landing page surfaces while it still matters, not after a bad month.
Fair scoring for any site
Scores come from Google's Lighthouse lab data, which works for any URL and does not depend on traffic volume. New and low-traffic sites get a real, comparable measurement from day one.
Hours back every week
No more working through a spreadsheet of URLs by hand. The checks run on their own, so the time you spent re-testing sites goes back into fixing the ones that actually need it.

Google PageSpeed: frequently asked questions
Does VigilDeck use field data or lab data?
It uses Google's Lighthouse lab data, the same engine behind PageSpeed Insights. Lab data works for any URL and gives new or low-traffic sites a fair, comparable score, whereas field data from CrUX needs enough real-world traffic to exist at all.
How often are checks run?
Free plans are checked weekly and paid plans daily. On top of that, VigilDeck runs an immediate check the moment you add a site.
Do I ever have to run PageSpeed manually?
No. That is the point. VigilDeck runs the checks on a schedule for every site, so you never open PageSpeed Insights and paste URLs one by one.
Are mobile and desktop tracked separately?
Yes. Both strategies are scored and stored independently, because a site can perform very differently between the two and mobile is what most visitors and Google see.
What exactly is recorded each check?
The headline performance score plus core sub-metrics including Largest Contentful Paint, Speed Index, Total Blocking Time, and Time to Interactive, all charted over time.
How far back does the history go?
History depth follows your plan, from 7 days on Free up to 1 year on Pro and unlimited on Agency. See pricing for the details.
