Google Ads conversion tracking for cannabis businesses
The first honest thing to say about cannabis marketing is that Google, Meta and TikTok will not knowingly run your ads, and no measurement work changes that. What Google Ads adds on top of that is a mechanical requirement: gclid, gbraid and wbraid have to reach the record that holds the money, because Google Ads can only credit a conversion it can tie back to a click it recognizes. This page covers both halves — what a conversion is in cannabis businesses, and what Google Ads specifically needs to accept it.

Google and cannabis: no Ads build, measure organic and maps
Google Ads does not allow cannabis product ads, so a dispensary has no gclid conversion to send. Track online orders and loyalty signups from organic search and Business Profile traffic in GA4 with UTM-tagged profile links, and send only an order value and channel, never the basket.
Google's policies prohibit advertising cannabis products, and the narrow exceptions that exist for hemp-derived CBD are limited to specific product types and locations, with certification required. Verify the current terms before anyone builds a conversion action, because for a dispensary there is usually nothing to build. Google still matters enormously as a source of customers: "dispensary near me" searches and map results drive much of the online ordering in this category.
That traffic is measurable, just not through Google Ads. Tag the website link on your Business Profile with UTM parameters so profile-driven sessions are separated from ordinary organic, and pass those parameters onto the online order so pickup and delivery revenue is attributed to the profile rather than to direct. Business Profile also reports calls and direction requests in aggregate, which is the only view of customers who walk in without ordering.
The specific way this breaks is the age gate. Many dispensary sites redirect first-time visitors to a 21-plus confirmation page and then send them on to the homepage, dropping the original URL and its UTM parameters. Every profile visit then lands as direct or unattributed. Make the gate an overlay on the requested page, or carry the full URL through the redirect, and test it from a clean browser.
Google Ads · Cannabis · what breaks
Why Google Ads under-reports for cannabis businesses
- 01
Major ad platforms unavailable
Not a tracking problem and not fixable by one. Any agency proposing Google Ads conversion tracking for a dispensary is either uninformed or hoping you are.
- 02
Marketplace and delivery platforms holding the customer
Weedmaps, Leafly and delivery apps sit between you and the buyer, and they do not hand over the click.
- 03
In-store revenue disconnected from everything online
Most dispensary revenue is a counter transaction with no link to any online activity.
- 04
Gclid, gbraid and wbraid never reaches the record
Three parameters, not one. gclid is the long-standing identifier; gbraid and wbraid arrive on iOS traffic where privacy constraints prevent the usual one. Capture code that names only gclid loses a growing share, silently, and the loss is invisible until you audit how many records carry an identifier.
Google Ads · Cannabis · the fix
What working looks like — Google Ads · Cannabis
Measurement built on channels you can actually run
Organic, email, SMS, cannabis-specific networks and marketplaces — each measured properly rather than lumped together.
In-store revenue bridged where a bridge exists
Through loyalty accounts and online ordering, with the join rate stated as a number.
Compliance-aware data handling
Purchase history in this category is sensitive. It should not be leaving your systems to a general-purpose ad platform, and mostly it cannot anyway.

How Google Ads and cannabis businesses actually connect
- 1
The conversion in cannabis businesses
The conversion map here starts with an eligibility question rather than an event: which channels can you legally and practically run? Everything downstream is scoped to those, and the honest map is smaller than in most categories.
- 2
Google Ads needs a click to match
A click identifier inside the 90-day window, a conversion action name that matches one configured in the account, a conversion timestamp for when the outcome happened, and a value. Read the match rate after uploading — a file can upload perfectly and match nothing.
- 3
The identifier: gclid, gbraid and wbraid
Three parameters, not one. gclid is the long-standing identifier; gbraid and wbraid arrive on iOS traffic where privacy constraints prevent the usual one. Capture code that names only gclid loses a growing share, silently, and the loss is invisible until you audit how many records carry an identifier.
- 4
Where it gets sent from
Your point-of-sale and online ordering records — transactions by date and channel, for the same window.
- 5
Deduplication and window
There's no shared event ID mechanism like Meta's. What matters instead is the counting setting on each conversion action — 'one' for lead-type conversions so a repeat submitter doesn't count three times, 'every' for ecommerce where a second purchase is a second sale. This is the single most common misconfiguration we find in Google Ads accounts. Google's offline import window is 90 days from the click. Anything older can't be matched, and rows outside it fail as unmatched without much explanation. Measure your median click-to-outcome time against that before designing anything.

The conversion map for cannabis businesses
Five events across the channels that are actually available to a cannabis business.
| Event | What it means here |
|---|---|
| Marketplace referral | Weedmaps, Leafly and similar. They pass a referral you can capture, not a click ID you can bid on. |
| Online order placed | Pickup or delivery. The cleanest measurable conversion in the category. |
| Loyalty signup | The bridge to in-store, and the highest-value online action for a dispensary. |
| In-store transaction | Joined only via loyalty or an online order. Otherwise unattributable. |
| Repeat purchase rate | Where the economics of this business live. Reported, not sent anywhere. |

Assuming the major platforms are an option
They are not, and building measurement for campaigns that cannot run is wasted money.
- 03
Marketplace platforms holding the relationship
You get an order, not an attributable click. Report marketplace revenue as its own channel.
- 04
Loyalty capture that depends on staff asking
The join rate then varies by shift and by store, which makes the number unstable.
- 05
Read the match rate on the upload, not the success message
A conversion action that stops receiving hits is flagged as inactive 30 days later — by which point a month of budget has already run against a missing signal. Check the last-received date on every action monthly; it takes two minutes and it's the cheapest monitoring available.

Source of truth
Your point-of-sale and online ordering records — transactions by date and channel, for the same window
- A channel eligibility review before any measurement work, so nothing is built for campaigns that cannot run.
- Online orders reconciled per order against each measurable channel.
- The in-store join rate measured and stated, rather than implied.
- A written statement of what leaves your systems and what does not.
- The match rate on the upload, not the success message read directly, not inferred from an upload succeeding.

Google Ads · Cannabis · when not to buy
When you don't need this — Google Ads · Cannabis
- If Google Ads already reports conversions that reconcile against your point-of-sale and online ordering records within a few percent, this is working and there is nothing to buy.
- Measure identifier coverage yourself first — pull your last hundred records and count how many carry gclid, gbraid and wbraid.
- If you're running Performance Max exclusively and haven't separated your conversion actions, the import will work and the reporting won't tell you much. Worth sorting the account structure first.

FAQ
Google Ads · Cannabis questions, answered
Not for cannabis products. Google's exceptions cover narrow hemp-derived CBD cases with certification in limited places, so verify current terms rather than relying on any summary.
Often because the age gate redirects visitors and drops the UTM parameters. Make the gate an overlay or preserve the full URL through the redirect.
Not for cannabis products. Both prohibit it, and accounts that try get suspended. Some ancillary and CBD businesses have narrow paths under specific conditions, which change often enough that you should verify current policy directly rather than trusting any agency's summary — including ours. Measurement work for campaigns you cannot run is money burned.
Organic search, email, SMS, cannabis-specific ad networks, marketplace referrals, and your own online ordering. That is a genuine program and for most dispensaries it is under-measured today, which is where the return is.
For the share of customers who use a loyalty account or ordered online, yes. For an anonymous cash purchase, no — and any vendor claiming otherwise is describing modeling rather than measurement. We publish the join rate rather than burying it.
