Your Google Ads says 48 leads. Your WhatsApp says 6.

A typical Dubai account I audit looks like this. Forty-eight conversions last month, cost per lead under AED 200, and Performance Max asking for more budget. Then the owner scrolls through his WhatsApp and finds six real inquiries.

The rest were taps that never became a message, two job seekers and a supplier selling cleaning services. Google counted every one as a win. PMax went looking for more of the same.

Heading into 2027, Google is pushing harder toward PMax and AI Max, and this is where most budgets leak. This post covers the tracking mistakes behind it, what the experts say, and the order I fix them in.

The Short Answer: Performance Max bids on whatever you mark as a primary conversion. If taps, page visits and duplicate form fires count as leads, it learns to find people who tap and never buy. Fix the tracking and send qualified leads back to Google before PMax gets the budget.

What This Means for UAE & GCC Businesses: WhatsApp is where leads land in Dubai, Riyadh and Kuwait City, and Google cannot see inside those chats. Google’s call forwarding numbers are not offered in the UAE or Saudi Arabia, so most accounts here count a call click, which is only a tap. Add job seekers searching the same service words in English and Arabic, and PMax in this region starts with weaker signals than any US playbook assumes.

What the experts are saying

Where they agree: primary conversions are instructions

Brad Geddes, founder of Adalysis, sets out the rule in his October 2026 piece for Search Engine Land. A primary conversion is what Google bids toward, while a secondary one is there only to observe.

His warning about easy actions is the one I see most. When a conversion is too easy for Google to get, such as a page view, it tends to become the most common conversion in the account.

Google’s own guide to PMax for lead generation agrees. It says the AI is only as good as its inputs, and tells advertisers to choose the goal closest to a sale, with at least 15 conversions in the last 30 days. It also warns that bidding toward two funnel stages in one target CPA strategy can be duplicative.

For a service business, that splits the conversion list into two groups:

• Primary: submitted forms that reach the inbox, booked appointments, and leads your team has marked as qualified.
• Secondary: WhatsApp taps, call clicks, contact page visits, chat opens, form starts and video views.

Arin Gharapetian of Brand House makes the same split in his August 2026 checklist. Get it wrong and every other fix below polishes a number that was never a lead.

The counting mistakes that inflate the number

Geddes separates two problems people lump together. Overcounting is one person converting several times. Double counting is the same conversion recorded across Analytics, offline imports, third-party tools, the Ads tag and Tag Manager.

For leads, the fix for overcounting is the “One” count setting. Purchases stay on “Every,” since each order is real revenue. Double counting needs a hunt, and duplicates hide in places like these:

• A Google Ads tag and an imported GA4 event counting the same form.
• The same tag hard-coded on the site and loaded again through Tag Manager.
• A button click and the form submission both set as conversions.
• A thank-you page that fires again on refresh, on the back button or from browser history.

Gharapetian’s test for that last one is worth copying. Submit once, refresh, return from history, then try an incomplete form. Only the first should count.

The feedback loop most accounts never close

The rest of Geddes’s list covers what happens after the form. With a 30-day click window, an offline update sent on day 31 won’t count, because the window has closed. If the form never stored the click ID, there is nothing to match the lead to.

He also flags campaign-level conversion goals, where a campaign can be set to use different actions from the rest of the account. Nobody remembers changing it. PMax still follows it.

Google has made the matching side easier. Its help center now recommends starting with enhanced conversions rather than plain offline import, which it describes as a legacy feature. Data Manager can pull qualified leads from a Google Sheet, so a business without a CRM still has a route.

Gharapetian adds two cautions. Google Ads can credit a conversion to Monday’s ad click while Analytics reports it on Wednesday, when the form was actually sent. And tracking breaks quietly after plugin updates, page rebuilds and new cookie banners, while the old tags keep reporting numbers.

Where they split: whether PMax finds good leads alone

Google’s guide presents PMax as a way to find high-quality leads at scale across all its channels. Practitioners are less generous.

Laura Schiele, writing for Search Engine Land in 2026, says that left to itself, PMax excels at two things: driving volume and finding the lowest-quality leads it can. Corey Frankosky of Surfside PPC advises staying on Google Search and being careful with PMax, which he says often brings in weaker leads.

Both sides are describing the same machine. Google assumes it is being fed deeper-funnel conversions. The practitioners describe accounts where the form fill is the finish line.

Why I hold PMax back longer than Google does

I agree with Geddes on every point, and with Google’s guide in principle. Where I push back is the 15-conversion line.

Google means 15 conversions close to a sale. Most accounts I see in the UAE read it as 15 of anything, and 15 WhatsApp taps tell PMax nothing about who books.

The region makes it harder. With no forwarding numbers in the UAE or Saudi Arabia, the “calls” in most accounts are taps. WhatsApp hides the outcome of every chat, and job seekers type the same service words as buyers, in both languages.

The hardest part is the front desk, not the tag. I have seen lead sheets work perfectly for a week and then stop, because nobody owned the job of marking which chats became bookings. Give that job to one named person.

The most common mistake is moving to PMax because the conversion count looks healthy. My order doesn’t change:

1. Run exact match Search on Maximize Clicks while the tracking is checked.
2. Make a qualified lead the primary goal. Taps stay secondary.
3. Move to Maximize Conversions at 15 to 30 verified leads a month.
4. Add PMax once that holds for two months running, with Search keeping most of the budget.

That last step matches what I wrote about how PMax fits with the other networks. It works best alongside Search.

What to do next

Most of this fits into one afternoon. Start with the account you already have, before touching budgets or campaign types.

1. Open Goals, then Summary. List every primary conversion and move anything that is a tap or a visit to secondary.
2. Test each primary conversion the way a customer would: submit, refresh, go back, and send an incomplete form. Use Google Tag Assistant to confirm it fires once.
3. Set the phone field placeholder to “+971” or “+966” so every number carries a country code for matching later.
4. Start a lead sheet with date, source, phone or email, and status. One person updates it daily.
5. Connect that sheet through Data Manager with enhanced conversions for leads, and make “qualified lead” the primary goal once it has volume.

After that, PMax has something true to learn from. Audience signals and remarketing lists only pay off from this point.

Before you copy a US checklist

Most of the advice above was written for markets with call tracking numbers and a CRM at every front desk. A few points change in Dubai, Abu Dhabi, Riyadh and the rest of the GCC:

• Calls: Google forwarding numbers are not available in the UAE or Saudi Arabia, so a call click is a tap. A third-party call tracking number can fill the gap if calls are your main lead source, but confirm it supports UAE or Saudi numbers before you pay. Until then, count a call as a lead only once it appears in your lead sheet.
• WhatsApp message assets: a tap is recorded as “conversation started.” Keep it secondary.
• Ramadan: if a bid strategy switch lands in Ramadan, give it extra weeks before you judge it.
