Tracking codes and analytics pixels

Tracking codes are small snippets of JavaScript from services like Google Analytics or Meta that measure who visits your site, where they come from and what they do. With them you can see which promotion works, and run ads that reach people who already visited your marketplace.

The admin panel already shows basic numbers under Analytics (see Analytics). Add a tracking code when you need more: traffic sources, audiences, conversions or ad campaigns.

Google Analytics

Google Analytics has its own place in the panel: go to Add-ons, open the Google Analytics card (in the Analytics tab), paste the whole Google tag snippet and click Save. The code is then added to every page of your site. See Google Analytics for the step-by-step guide.

Any other tracking code

Everything else goes into the head of your pages:

1. Copy the code from the service. For the Meta Pixel, Google Ads, TikTok, LinkedIn, Pinterest, Hotjar, Microsoft Clarity or Google Tag Manager this is usually called the “base code” or “install code”.
2. In your admin panel, go to Design › Custom code.
3. Paste it into Code in the page head. If there is already code in the box, paste yours on a new line below it.
4. Click Save changes in the bar at the bottom.

Some services also give you a second part to place “right after the opening body tag” (Google Tag Manager does, for example). Put that part into Code in the footer: it works there too, and it is the only other place you can add code.

These boxes used to be in Settings › General › Advanced. Codes you added there before are now in Design › Custom code and keep working. See Add code to the head and footer for what the boxes do and how your site protects you from broken code.

Use Google Analytics or Google Tag Manager with an Analytics tag inside, not both, or every visit is counted twice.

Tips

• One code, one place. Pasting the same pixel twice counts every visit twice. Before adding a code, check Code in the page head and the Google Analytics card for an older copy.
• Test with the service’s own tool. Meta’s Pixel Helper, Google’s Tag Assistant and similar browser extensions show whether the code fires on your pages.
• Broken code can break pages. A missing </script> can stop menus or buttons from working. If something breaks right after you add a code, remove it and paste it again carefully. See Add code to the head and footer.
• Tracking codes and privacy. In the EU, UK and some other places you need visitors’ consent before setting tracking cookies. Switch on Ask for cookie consent in Settings › General (see Cookie consent and privacy): Google Analytics then waits until the visitor accepts Analytics, and the code in Design › Custom code waits for the category you choose there. Pick Marketing if your codes are ad pixels (Meta, Google Ads, TikTok), Analytics if they only measure visits (Hotjar, Clarity). The older Cookie notice only informs visitors and blocks nothing.
