How to audit analytics and ad tags on a dealer website

Dealer sites collect tags: analytics, one pixel per ad platform, call tracking, retargeting, and old pixels from past agencies. Each loads its own code, and some load more. Audit them once a year: list every tag, find who owns it, remove the ones nobody uses, and let the rest load after the vehicle and price.

How tags pile up

Every new agency, campaign and manufacturer program adds a tag. When the agency or campaign ends, the tag usually stays.

A tag manager connects to analytics, an ads pixel, a social pixel, call tracking, an old agency pixel and retargeting. Each tag loads its own code and more requests.

How to audit your tags

  1. 1

    List what loads

    Open a vehicle page in Chrome, open the Network panel, and note every tracking domain. Check the tag manager container too.

  2. 2

    Name an owner for each

    Marketing, an agency, the manufacturer, or nobody. Nobody usually means remove.

  3. 3

    Remove duplicates and orphans

    Two copies of the same analytics tag, or a pixel for an agency you left, can go after the owner confirms.

  4. 4

    Load the rest after the vehicle

    Tracking still records the visit. Site Speed Engine does this automatically.

Questions

Do tracking pixels slow down a website?

Each one adds code and requests. A few are fine; a dealer site with a dozen pixels from past and present agencies loads noticeably slower on phones.

How do I audit Google Tag Manager tags?

Open the container, list every tag with its trigger and owner, and pause the ones nobody can account for. Check the site still reports correctly before deleting.

Can tracking load after the page without losing data?

Yes, for page views and conversions. Loading tracking a moment after the vehicle still records the visit.
