If Performance Max reports 40 conversions and your sales team recognizes 10 leads, start by checking what those 40 conversions count. A call-button click, a form submission, and a qualified enquiry can all appear in reporting, but they represent different stages of the customer journey.
The difference could come from your conversion setup, attribution, reporting dates, duplicate events, or poor-quality enquiries. You need to identify which explanation fits before changing the campaign.
Check the conversion actions behind the total
Segment the campaign's results by conversion action. Open those actions under Goals → Conversions → Summary, then compare them with the campaign's selected goals.
Look for phone-link clicks counted as leads, visits to confirmation pages, imported Analytics events, and offline outcomes. Check whether the same form completion is being counted through both a Google Ads tag and an imported Analytics event.
A preliminary enquiry and a later sale may both be useful to record. Treating them as two equivalent primary conversions can make the total hard to interpret and give bidding a different objective from the one you intended.
Separate view-through and engaged-view conversions
Ordinary view-through conversions count qualifying conversions after an ad impression without an interaction. They appear in the View-through conversions and All conversions columns, not the main Conversions column. They are not a hidden component you need to remove from that main column's bidding total. Google's conversion reporting guide.
Engaged-view conversions are different: they follow qualifying video engagement and can be included in Conversions. A conversion therefore does not always require a click, and an impression alone is not the same as a qualifying video engagement.
Check each action's configured conversion windows rather than assuming they all use 30 days. Google's window settings distinguish click-through, engaged-view, and view-through windows.
Reconcile the report with your lead records
Choose one outcome to compare, such as completed form submissions or qualified leads. Match the date range, time zone, counting rules, and conversion definition. Check whether the Google Ads report is organized by the ad interaction date or conversion time, and allow for leads that have not yet progressed through your sales process.
Then inspect individual records where you can:
- Did the form complete successfully, or did only the button click fire?
- Did the same lead appear more than once?
- Was the enquiry relevant to the service and location?
- Did it become qualified, book an appointment, or buy?
- Was that later outcome uploaded successfully?
An accepted upload and a reported attributed conversion are different checkpoints. Use upload diagnostics and compare like-for-like outcomes before interpreting a gap as fraud or a tracking failure.
Check how much traffic comes from brand searches
PMax can receive conversions from people searching for your brand. That can make a campaign look efficient without showing how much new demand it created.
Use the available search-term reporting to inspect branded traffic. If you want to manage brand searches separately, apply the appropriate brand exclusions to the PMax campaign. Account-level negative keywords also affect other relevant campaigns, so they can interfere with a branded Search campaign you intend to keep running. Google's PMax control guidance.
Excluding brand changes the traffic the campaign can reach. A resulting fall in PMax conversions is not, by itself, a measure of wasted spend. Likewise, a nonbrand click that becomes a customer is not proof that the ad caused a sale that would otherwise never have happened. Assessing that additional effect requires a suitable experiment, not just a before-and-after screenshot.
Improve the outcome the campaign learns from
If the campaign's goal is qualified enquiries, define qualification in terms your sales team can apply consistently. Record that outcome, verify the upload process, and review how long it takes to arrive in Google Ads before making it a bidding goal.
If you use revenue, upload genuine sale values or clearly defined estimates. Keep early-stage events available for diagnosis without automatically giving every stage equal importance in bidding. Google's primary and secondary conversion guide explains the settings, including the custom-goal exception.
Fix a duplicate event or incorrect goal as a measurement problem. Address genuine irrelevant enquiries as a lead-quality problem. Keeping those findings separate makes it easier to choose the next campaign change and judge whether it helped.
