What you know before you decide
Your purchase rate fell in one segment — Channel: Paid social — 31 fewer sessions reached purchase than the baseline rate would have produced over 3,140 sessions.
- Evaluated, Jan 5, 2026 – Jan 11, 2026
- 1.8 % of 3,140 sessions
- Baseline, Dec 8, 2025 – Jan 4, 2026

Incomplete days, named instead of counted
When a step stops arriving, TraceLog hides the figures that count it over those days and names the days instead.
Every plan
Conversions only the server saw
TraceLog counts each purchase once, whether the browser, the server or both saw it, and says how many only the server saw. Where a server confirms the order.
From Pro
The tag your page stops requesting
Confirm a GA4, Meta or Google Ads tag beside a conversion and TraceLog alerts you when the page stops requesting it. It says the page stopped asking, never that the platform lost data, and never why. Not on Shopify.
From Pro, €39 a month
Where your conversion changed
Compare it by channel, campaign or device across periods. With enough traffic and history, TraceLog alerts you to what fell.
TraceLog checks its own record and nothing beyond it
What it tells you
- Which step stopped arriving, and since when.
- Which TraceLog figures are incomplete.
- When the fault is TraceLog's own.
What it does not tell you
- Why it happened.
- What to do: what you change is your decision.
- Whether GA4, Meta or Google Ads received their data.
Start free, pay to compare
A channel can fall while the total barely moves. Paid plans show where.

Answered before you start
How do I install it?
With a snippet on your site, or on WooCommerce with the plugin from the WordPress.org directory. The Shopify app can be installed once Shopify approves it. The TraceLog module is not listed on the PrestaShop Marketplace yet. Write to info@tracelog.io and we will send it to you.
Does TraceLog replace GA4?
No. TraceLog runs alongside GA4, Meta and Google Ads as an independent control. It does not inspect, repair or reconcile their data. It does tell you how many conversions reached it from the server alone and not from the browser. You see it on Shopify, on WooCommerce, on PrestaShop, or when your server confirms the conversion.
How much traffic do I need?
The free plan is enough to know whether your TraceLog figures are missing data. On a paid plan, detecting a fall takes 1,000 sessions in the week it compares and five weeks of data. A single channel or campaign needs more. Below that, TraceLog stays quiet rather than guessing.
What happens if I go over 10,000 sessions?
TraceLog keeps capturing the declared conversion path without sampling. At the limit, alerts, answers and Analytics pause.
Does TraceLog use cookies? Where does the data live?
The capture code sets no tracking cookie. After consent, one session identifier lives in the visitor's browser storage. This site sets one cookie, only to remember your language. Conversion data lives in the EU.
