Define your conversions once and TraceLog checks them every day
After a change of theme, checkout, consent setup or platform, a step can stop arriving with no error shown.
Define what should arrive
Name each conversion and the steps before it. On WooCommerce and PrestaShop, the plugin or the module sets them up.
Verify the installation
Go through each step once while you install. If something does not match, TraceLog says what to check.
TraceLog watches it every day
An alert names the days a step stopped arriving.
If a step goes missing, TraceLog withholds the figures it affects
The record can be incomplete while your site keeps selling. Decide on those days and you decide on incomplete figures. TraceLog says what you can still count and which figures it withholds.

- Sessions with a complete count
- 1,400
- Affected conversion figures
- TraceLog did not receive
purchasefrom Wednesday, January 14 to today, Thursday, January 15. Every figure that counts it over those days is incomplete, so this one is not shown and no period including them is compared.
Even after the event returns, periods containing affected days remain incomplete.
Every plan
Who saw each conversion
Each purchase counts once. Where the server confirms the order, it shows who saw it: browser, server or both.
From Pro
Tag watch
Alerts when the page stops requesting a GA4, Meta or Google Ads tag you confirmed. Requires code in the page; excludes Shopify.
From Pro
Comparison and segments
Compare periods, channels, campaigns or devices with complete figures. Upgrading opens all the history kept.
From Pro
Statistical detection
With enough traffic and complete weeks to compare, it names the conversion, step or segment that fell. It never says why.

- Which TraceLog figures are incomplete.

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.
Answered before you start
Do I have to define the conversion path myself?
On Shopify the app sets it up and you confirm it. On WooCommerce and PrestaShop the plugin or module sets it up, and you see it before connecting the store. On a site of your own, you give three things: the conversion, its ID (the order number, say) and the steps before it.
How much traffic do I need?
Free is enough to know whether your TraceLog figures are missing data. An alert needs a step that has been arriving steadily, on five of the last seven days. TraceLog then alerts the morning after a full day without it. A step that arrives fewer than ten times a day needs seven days in a row. On a paid plan, detecting a fall takes 1,000 sessions in the week it compares and five whole weeks of data. A single channel or campaign needs more. Below that, TraceLog stays quiet rather than guessing.
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.
I already send conversions from the server. Is it still useful?
Keep doing it: that is how the platforms receive them. TraceLog works alongside it as an independent control over its own record and replaces none of it. It says the day a step stopped arriving and which TraceLog figures that leaves incomplete. If you already hear the next day that something stopped being recorded, you do not need it.
Does it depend on consent?
In the browser, yes: TraceLog sends nothing until the visitor consents, and nothing if they refuse. Where the server confirms the conversion, TraceLog counts it even if the browser never sent it. That is built in on Shopify, WooCommerce and PrestaShop, and an optional call on a site of your own. It says how many only the server saw, out of the total, never why. To tell whether a step stopped arriving, TraceLog looks at what does arrive.
What happens if I go over 10,000 sessions?
TraceLog keeps recording your whole conversion path, without sampling. What pauses are the alerts, the answers to your questions and Analytics.
If your site is already past 10,000 sessions a month, request a demo before installing.
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.
