What are Web Vitals and error monitoring?

Core Web Vitals are Google measures of real user experience, loading speed through LCP and FCP, server response through TTFB, responsiveness through INP, and visual stability through CLS. Alongside them Air360 tracks the technical errors your visitors actually encounter, monitored in real time rather than sampled from a synthetic test.

Why monitor them next to behaviour?

Performance data in a separate tool answers a different question from the one you are asking. When conversion falls on a step, what you need to know first is whether those sessions were slow or hitting errors, because that decides whether the fix is engineering or design. Core Web Vitals are also part of how Google assesses pages, so the same work that stops visitors leaving tends to help how the page is judged in search.

What the first week looks like

Look at the pages with traffic first, not the pages with the worst scores. A poor score on a page nobody visits costs nothing, and a mediocre one on your highest-traffic template costs every day. Check the numbers against the devices your visitors actually use rather than a lab result, then confirm with replays that the delay is one people notice. Some slow steps are invisible in practice and some fast ones still feel broken.

Where it fits with the rest

Vitals and errors answer whether the problem is technical. That is worth establishing early, because it is the cheapest explanation to rule in or out. If the step is fast and error-free and people still leave, the answer is in the funnel, the zoning or the replays instead. Running the technical check first stops teams from redesigning a page that was only ever slow.

Common questions

Everything you need to know

Error tracking includes monitoring for JavaScript errors. Comprehensive error tracking helps in quickly identifying and resolving these technical glitches to maintain website functionality and reliability.
Air360 tracks, Interaction to Next Paint (INP), Cumulative Layout Shift (CLS), Largest Contentful Paint (LCP), First Contentful Paint (FCP),Time to First Byte (TTFB).
LCP and FCP for loading, TTFB for server response, INP for responsiveness, and CLS for visual stability, measured on real visits rather than in a synthetic test.
It separates an engineering problem from a design one. Before redesigning a step that lost people, you can check whether those sessions were slow or hitting errors, which is a much cheaper thing to fix and a much more common cause than teams expect.
Core Web Vitals are part of how Google assesses page experience, so work that stops visitors abandoning a slow page tends to help how that page is judged in search as well. The two goals point the same way more often than not.
Yes. Page Analysis reports Core Web Vitals and errors for a specific page alongside its engagement and conversion, which is usually how teams decide what to fix first.
