Your website still brings in enquiries, but Google Ads suddenly reports none. Perhaps a release removed a conversion tag, a new form stopped triggering it, or an import stopped delivering sales outcomes. Before changing bids, establish whether customers stopped converting or the measurement stopped working.
For a confirmed conversion-data outage, a Google Ads data exclusion can help limit the effect on Smart Bidding. The important decisions are which clicks were affected, which campaigns need the exclusion and how you will prove that reliable measurement has resumed.
First, confirm that conversion data is actually missing
A blank conversion column this morning does not establish an outage. Google’s data freshness guidance explains that conversion reporting takes time and varies by conversion source and attribution model. Customers can also convert some time after clicking.
Start with a comparison you can substantiate:
- Business records: did genuine enquiries, paid orders or qualified sales outcomes continue during the suspected gap?
- The affected conversion action: which specific action stopped recording, or started recording an implausible count or value?
- A technical change: was a form, checkout, thank-you page, tag configuration or import process changed around the same time?
- The customer route: does the failure affect every visitor, one device type or only a particular form or checkout?
A CRM enquiry proves that someone contacted you; it does not, on its own, prove that Google Ads should receive an attributed conversion. Use it to identify the discrepancy, then investigate the measurement route.
For website tags, Google’s Tag Assistant troubleshooting process lets you start from a landing page, complete the conversion journey and inspect the test result. If the conversion comes from an import, ask whoever maintains that connection for its delivery and error records instead.
If a button click was always being counted as a completed enquiry, address the conversion-goal setup too. An exclusion cannot make an unsuitable goal useful.
Understand what a data exclusion changes
Google’s data exclusion documentation says the tool changes the data Smart Bidding uses. It leaves conversion reporting unchanged. It is available for conversion-based and conversion-value-based Smart Bidding in Search, Display, Shopping and Performance Max; Hotel and Travel campaigns are unsupported.
That means an exclusion can address the bidding implications of unreliable data. It does not repair a tag, restore an import or fill the missing figures in your report.
Keep those jobs separate in your recovery plan. Someone needs to fix measurement, someone needs to review bidding exposure, and someone needs to explain the reporting gap. In a small business, the same person may own all three, but each still needs an explicit outcome.
Do not choose an exclusion simply because a campaign had a disappointing week. First document the specific measurement fault. If customers could not complete the form or checkout either, investigate that lost customer journey alongside the tracking problem.
Choose affected click dates, including conversion delay
The date a customer enquires may be later than the date they clicked an advert. An exclusion covering only the hours when the tracking tag was broken can therefore miss earlier clicks whose eventual conversions were affected.
Use historical evidence to understand that gap. Google explains how to check conversion delay using the Days to conversion segment and bid strategy reports. Its instructions recommend using a reporting period that ends at least 30 days ago, or longer for a longer conversion window, so the historical data is complete.
Google’s outage guidance recommends acting promptly and covering at least 90% of clicks associated with the affected conversion data, allowing for conversion delay. Assess the exclusion alongside the technical repair.
A simplified example
Suppose tracking failed from 20 to 22 October, while the business continued receiving enquiries. If your evidence supports allowing five days for the relevant conversion delay, your review would include clicks from 15 October through 22 October. These are illustrative dates, not a recommended range for every account.
Record the actual start and end times as well. If you cannot establish when the problem began, compare release records, the last known successful event and the first confirmed failure. Make the uncertainty explicit rather than treating an estimated timestamp as fact.
Do not automatically exclude an entire month because one report looks incomplete. Explain how your chosen range covers the fault and the associated earlier clicks.
Limit the scope to what the evidence supports
The exclusion setup supports campaign and device selection, with start and end times based on the Google Ads account’s time zone.
If the failed route served only certain campaigns, review those campaigns first. If you can demonstrate that the fault was confined to mobile tracking, assess the mobile scope. Avoid extending an exclusion to healthy traffic just because selecting the whole account is easier.
Also ask which other conversion actions those campaigns use. A campaign may measure both website enquiries and telephone calls. Since the setup is scoped by campaigns and devices, review the implications for healthy conversion data before proceeding.
Write down the proposed scope in plain terms: the fault, affected customer route, selected campaigns, devices, click period and supporting evidence. This gives the person applying it something concrete to check.
Create the exclusion and keep a recovery record
Google’s current setup instructions direct you to Tools, then Adjustments, then Exclusions. Add an exclusion, describe the incident, enter the dates and scope, and review the information before creating it.
Use a description that will make sense during next month’s review: for example, which form release caused the measurement gap and where the test evidence is stored. Avoid names such as “bad week”.
Record the original budgets and bidding targets alongside any recovery changes. Agree the maximum affordable spend and who will review it. If a target is adjusted during recovery, give that change an owner and a review date so a temporary response does not become an unexplained permanent setting.
Do not rush to backfill or remove the exclusion
Google advises retaining applied exclusions and generally discourages backfilling because it can affect bidding. For a reporting backfill following an exclusion, wait at least five days after applying it.
That waiting period is not permission to upload a spreadsheet of estimated conversions. Before any backfill, establish whether the original conversion source has a supported recovery method, whether the records can be matched correctly and whether the same events could arrive later through the repaired connection.
If the missing outcomes cannot be recovered reliably, retain an honest reporting annotation and the underlying business records. An explained gap is more useful than a seemingly complete report built from assumptions.
Verify measurement and commercial recovery separately
Start by repeating the customer journey after the repair. For a website enquiry, check that the form completes, the enquiry reaches the intended team and the expected measurement event is detected. For an import, confirm delivery and acceptance through that integration.
Tag Assistant verification is useful technical evidence; it is not proof that every subsequent customer conversion has been attributed. Allow for reporting delays, then inspect the affected action and compare the pattern with genuine business outcomes.
Do not promise an overnight recovery. Google warns of fluctuations lasting one or two conversion cycles after a week or more of affected clicks, and harm from frequent or prolonged exclusions.
Set the next review around your conversion delay and trading needs. Check spend, the affected conversion action, enquiry quality or paid orders, and any temporary target changes. Use your enquiry-to-sale reporting to judge the commercial outcome.
Ask for a short handover containing the confirmed fault, repair evidence, excluded click period, campaign and device scope, budget decisions and next review date. That gives your business a usable recovery record rather than a reassurance that “tracking is fixed”.
