About Web Analytics

What is web analytics?

Web analytics is the tracking installed on a site to record how people arrive and what they do once there. Google Analytics is the most widely installed of these by a wide margin, and for most sites it is the only measurement they have.

Without something like it, you can see that traffic changed but not why, which makes every subsequent decision guesswork dressed as strategy.

An analytics checker answers the first question: is anything actually installed, and is there more than one of it. Duplicate implementations are surprisingly common and quietly double every number a business reports.

Does analytics still matter in 2026?

Measurement matters more than ever, precisely because it has become harder. Consent requirements, browser tracking prevention and ad blockers mean a meaningful share of visits go unrecorded, so figures are directional rather than exact.

That is an argument for understanding the gaps rather than abandoning measurement. Pair analytics with server logs and Search Console, both of which see things a client-side script cannot.

It is also worth auditing what you collect. Tracking accumulated over years often outlives the questions it was installed to answer, while costing load time and carrying a privacy obligation.

How analytics relates to AI search

This is where the blind spot is widest and least discussed. Traffic arriving from AI answers often carries no useful referrer, so it lands in reports as direct traffic and is easily mistaken for brand visits or mis-tagged campaigns.

Watching for unexplained growth in direct traffic to deep, specific pages is currently one of the few practical ways to notice you are being cited at all. Deep pages rarely receive genuine direct traffic, so a rise there is a signal rather than noise.

Expect reporting to lag reality here. The measurement tools have not caught up with how people are finding things.

Analytics best practices

Install exactly one tracking implementation. Duplicates double every number.
Filter internal and agency traffic so it does not distort reporting.
Track the events that matter commercially, not just pageviews.
Connect Search Console for query data analytics cannot see.
Watch direct traffic to deep pages as a proxy for AI citations.
Honour consent, and understand how it affects the numbers you report.

What this tool checks

The tool reports whether a Google Analytics implementation is present on the page.

It detects presence rather than correctness, so it cannot tell you whether the property is the right one, whether events are configured, or whether the data reaching your reports is trustworthy.

Where to go next

Analytics is one of several scripts a page carries. See everything else that is loading with the technology check, confirm those scripts are not costing you with the webpage file size tool, and check for JavaScript errors, which can stop tracking firing altogether.
