Google Ads Conversion Tracking: Not Converting, or Not Counting?

Two different problems hide behind "Google Ads is not converting". One is real: clicks arrive and nobody enquires. The other is counting: people do enquire, but Google Ads never hears about it, or hears about the wrong things.

The counting problem does more damage. Smart Bidding sets bids from the conversions you report. Report zero and it has nothing to learn from. Report an inflated number and it buys more of the wrong traffic. Our main Google Ads guide calls this the first leak: conversions that are not revenue. This page is the practical version.

So before you rewrite ads or blame the agency, confirm the count. When we take over an account through our Google Ads management service, tracking is checked before a single bid changes.

A conversion is the moment someone raises their hand. For most Malaysian SMEs, that means one of four actions.

WhatsApp is a proxy. Google Ads cannot see inside a chat, only the click on your button. Compare clicks with the chats your team actually received that week. If clicks are double the real chats, your true cost per lead is roughly double what Google Ads reports.

Calls are similar. Google's call reporting runs on Google forwarding numbers, and Malaysia is not on Google's list of countries where they are available (Source: Google Ads Help, About call reporting, checked October 2026). Google says mobile number clicks track the click, not the call, and for call ad clicks it estimates whether a meaningful call happened. If calls matter, log them in a CRM and use Import call conversions (Source: Google Ads Help, About phone call conversion tracking, 2026).

Both work. The Google Ads tag sends the conversion straight to Google Ads. A GA4 import shares a key event from Google Analytics with Google Ads.

Two traps. Google says conversions created from Google Analytics are secondary by default and can only be updated to primary in Google Ads (Source: Google Ads Help, About primary and secondary conversion actions, 2026), so a perfect GA4 lead event can still be ignored by Smart Bidding. And if the tag and the import both track the same form as primary, every lead counts twice. Pick one source per action and make it primary.

Primary actions are reported in the Conversions column and used for bidding when their goal is used for bidding. Secondary actions are observation only: they show in All conversions and are not used for bidding, unless they sit inside a custom goal (Source: Google Ads Help, 2026).

Google warns that getting this wrong can stop Smart Bidding from optimising effectively. Primary should hold only actions you would pay for: a form submit, a WhatsApp click, a call, a purchase. Page views, scroll depth and time on site belong in secondary, if anywhere.

Enhanced conversions for leads. Enhanced conversions sends first-party data from your form, such as an email address, hashed with SHA256, to improve the accuracy of conversion measurement (Source: Google Ads Help, About enhanced conversions, 2026). The leads version is built for sales that close offline. Your form sends hashed details when the enquiry arrives. When that lead becomes a customer, you import the same details from your CRM and Google matches the sale to the ad click (Source: Google Ads Help, About enhanced conversions for leads, 2026). For a clinic or an insurance agent, this teaches Smart Bidding the difference between an enquiry and a customer. It needs a working CRM and an import through Google Ads Data Manager or the API, so treat it as stage two.

Consent Mode v2. Consent mode passes visitors' cookie choices to Google and adjusts how Google tags behave. Version 2 added two signals, ad_user_data and ad_personalization. Google's requirement to collect and share consent applies to advertisers receiving data from users in the European Economic Area (Source: Google Tag Manager Help, Updates to consent mode for traffic in the EEA, 2026). Malaysia is not in the EEA, so for Malaysian traffic that requirement is not why conversions are missing.

It matters if you get European visitors or already run a consent banner. Google says basic consent mode blocks tags until the visitor responds to the banner, while advanced mode loads tags with consent denied, sends cookieless pings and supports an advertiser-specific conversion model (Source: Google Ads Help, About consent mode, 2026). A banner that blocks tags can make conversions vanish. Malaysian privacy law is a question for your lawyer.

1. Read the tracking status (3 minutes). Go to Goals, then Conversions, then Summary. Anything showing Unverified, Tag inactive or Needs attention goes to the top of the list. Hover on the status for a Troubleshoot option that opens Tag Assistant.
2. List what is primary (3 minutes). For each primary action, ask: would I pay for this? If not, make it secondary.
3. Check the count setting (2 minutes). Leads should be One. Purchases should be Every.
4. Look for duplicates (2 minutes). Do two primary actions describe the same thing, such as a form tag and a GA4 lead event? Keep one.
5. Run a live test (3 minutes). Open your site in Tag Assistant. Submit the form with a test entry, then click your WhatsApp and call buttons. Each should fire once, and nothing should fire when a page simply loads. Then open the thank-you page directly. If a conversion fires, anyone can trigger it.
6. Compare against reality (2 minutes). Compare last week's Google Ads conversions with the enquiries that reached your inbox, WhatsApp and CRM. A small gap is normal. Double, either way, means something is broken.

If you find a fault, fix the count first and leave bidding alone while the account settles, or you cannot tell which change moved the numbers.

Take a healthcare group we manage. In the 30 days to 24 September 2026, a newer service line campaign ran at RM59 per conversion against RM83 for the main Search campaign. That comparison guides where the next ringgit goes, and it only holds if both campaigns count the same action the same way. If one counted page views, the "cheaper" campaign could be the worse one.

The account's overall CPA has also risen four months running as spend scaled: RM55.11, RM61.45, RM69.46, then RM76.78 (211 conversions on RM16.2K). It is an uncomfortable trend, and it stays on our Live Results Board. A count padded with page views would have hidden it.

Scale raises the stakes. Take an account getting 1,000 real leads a month at RM5 per lead. A duplicate tag on one lead in ten adds about 100 phantom leads a month, and cost per lead looks about 9% better than it really is. Smart Bidding then chases the wrong signal.

Clicks are not cheap either. Top of page bids in Malaysia run from RM4 to RM77 for "google ads conversion tracking" and RM13 to RM320 for "google ads malaysia" (Source: Google Keyword Planner, Malaysia, October 2026). Bids vary hugely by keyword, but every click bought on bad data is real money.
