      What the quick scan checks

      The problems we find most often when a new client's reports don't add up.

      Tag Manager health

      Every container on the page, what's inside it, and whether any are empty, duplicated or unreadable.

      GA4 set-up

      Measurement IDs, duplicate properties, and leftover Universal Analytics code that's been dead since 2024.

      Ad and social pixels

      Google Ads, Meta, TikTok, LinkedIn, Pinterest, Microsoft Ads and more, and whether they load through GTM or around it.

      Cookie consent

      Which consent tool you use, if any, and whether marketing tags are running without one.

      Consent Mode v2

      The signals Google Ads needs to keep using UK and EEA conversion and audience data.

      Behaviour and CRO tools

      Clarity, Hotjar, Contentsquare, Optimizely and VWO, so you know what's recording your visitors.

      Questions

      Do you need access to my GA4 or GTM account?

      No. Both the quick scan and the full report only use what any visitor's browser can see.

      Is the full report really free?

      Yes, with no obligation. If you'd like us to fix what we find, we'll quote a fixed price first. In-depth audits that reconcile GA4 and your ad platforms against real orders are a separate paid service.

      Why can't the quick scan see everything?

      Some tags only load after someone accepts cookies, some run on a server rather than in the browser, and some sites block automated checks. The full report uses a real browser to cover those.

      Which platforms do you work with?

      Shopify, WordPress and WooCommerce, Magento, BigCommerce, Squarespace, Wix, Webflow and custom builds.

      Is this legal advice on cookies?

      No. We flag technical risks under UK PECR and GDPR so you and your advisers can act on them.

      Rather talk it through?

      Bring whatever's not adding up in your reports and we'll talk it through.
