Google Ads conversion parameter reference

Most Google Ads conversion problems aren't tags at all — they're conversion action settings that nobody read. Counting set to every on a lead form turns one repeat submitter into three conversions. Several actions marked primary split what bidding optimizes toward. An attribution window left at default silently disagrees with every other platform. These settings are free to change and they change your numbers more than most tag work does.

The problem

Where teams get this wrong

Google Ads conversions-specific issues
Leak #01

Counting set to every on a lead form

One person submitting three times becomes three conversions, and bidding goes looking for more repeat submitters.

Leak #02

Several actions marked primary

Bidding splits its attention and optimizes toward an average of things you value differently.

Leak #03

Flat conversion values

Bidding can't distinguish a small sale from a large one, so it finds you small ones.

Who this is for

Honest about who we’re a fit for.

We don’t take every project. Here’s how to tell if we’re right for you.

Good fit

You’re a great fit if…

  • You run Google Ads conversions (or are migrating to it)
  • You spend $5K+/month on paid ads (Meta, Google, TikTok, Microsoft, LinkedIn)
  • Your reported ROAS doesn’t match what your bank account is saying
  • You want to own your tracking stack — no monthly SaaS fees forever
  • You have 2–4 days to do this once and never think about it again
Not a fit

Skip us if…

  • You spend less than $500/month on paid ads (browser pixel is fine)
  • You want a SaaS dashboard with monthly fees forever (Triple Whale, Hyros)
  • You need attribution modeling — we fix the data foundation, not multi-touch reports
  • You want a 6-month enterprise consulting engagement (we ship in 4 days)
  • You expect us to manage your ad accounts (we don’t — that’s a different service)

If you’re still unsure,book the call anyway— we’ll tell you straight whether we can help.

Our position

If yourreported ROASdisagrees with your bank account, you don’t have an attribution problem.You have a data foundation problem.No SaaS dashboard fixes that — only a rebuilt 1st-party server-side stack does.

A typical engagement

The shape of a typical Google Ads conversions rebuild

We’re not going to invent a fake testimonial here. Instead — here’s the realistic pattern of what happens, anonymized but accurate to engagements we ship.

Day 0 — They arrive

A 7-figure Google Ads conversions store spending ~$25K/month on Meta. Reported ROAS shows 4.1× in Ads Manager. Their bookkeeper’s number says 2.6×. The founder doesn’t know which is real, so they keep doubling down on what looks like a winning campaign — except cash flow tells a different story.

Day 1 — Audit

We screen-share. Within 20 minutes we’ve found the leaks: native pixel firing twice on iOS, CAPI dedup using the wrong event_id (Meta is double-counting), GA4 showing 38% (not set), and the Customer Events API never enabled. The 1.5× ROAS gap explains itself.

Day 2–3 — Build

Server-side GTM container goes live on data.theirstore.com. Meta CAPI rebuilt with full advanced matching. Google Enhanced Conversions wired. TikTok Events API turned on. All event_ids deterministic. iOS recovered.

Day 4 — Launch

Live-fire test purchases through every funnel step. Meta Event Match Quality goes from 4.5 to 8.7 — verified live in Events Manager. They get a Notion runbook + Loom walkthrough so their dev team can extend it.

Day 5–7 — Accuracy

Conversion data starts flowing cleanly. Day 7: reported ROAS reads 2.8× (matches Stripe within 5%). Lookalike audiences grow because Meta finally has clean seed data. Their CAC dashboard makes sense for the first time in a year.

Day 30 — The math compounds

Smart Bidding has 30 days of clean signal. CPA drops 18%. They scale Meta budget 40% because they finally trust the data. Net new revenue from the recovered tracking: roughly $14K/mo above what they were getting before.

Numbers above are realistic averages from engagements we’ve shipped. Your specific recovery depends on your iOS share, ad-blocker rate, and current setup — we’ll quantify it on the call.

The cookie window unlock

400-day cookie lifetime — the longest your browser allows

Default Google Ads conversions setups put cookies on a 7–30 day timer. Safari ITP caps client-set cookies at 7 days. That kills your retargeting windows, shrinks lookalike audiences, and starves Smart Bidding of historical signal.

We set 1st-party cookies via HTTP headers on your own subdomain — exempt from ITP’s 7-day cap. Lifetime: 400 days. The maximum Chrome, Firefox and Safari currently permit.

  • 57× longer retargeting window vs Safari default

    Reach users who saw your ad 6 months ago instead of last week.

  • Bigger lookalike seed pools

    More retained users in your custom audience = better lookalike quality on Meta, Google, TikTok.

  • Smart Bidding has 13× more signal history

    Algorithms optimize on 400 days of behavior, not 7 days. CPA stabilizes faster.

  • Critical for high-AOV / long-consideration purchases

    If your average buyer takes 30+ days to convert, default cookies miss them. 400-day cookies don’t.

Cookie lifetime — head to head

How long cookies survive in real-world traffic

Safari ITP (default)7 days
Chrome / Firefox (typical)30 days
Meta default retargeting window90 days
Google Ads default cookie540 days(but capped by browser)
Our 1st-party server-side400 days

400 days is the hard maximum enforced by RFC 6265bis (Chrome 104+, Safari 17+, Firefox 110+). We set it via HTTP Set-Cookie: Max-Age=34560000 on your subdomain. Survives Safari ITP’s 7-day client-side cap.

Under the hood

What’s actually happening on your server-side stack

Six capabilities your default Google Ads conversions setup doesn’t have. Built on the same Stape Pro stack used by enterprise DTC brands.

Cookie window

Cookie Keeper

400-day 1st-party cookies

Set via HTTP headers on your subdomain — the maximum browsers allow. Survives Safari ITP’s 7-day cap that kills retargeting.

Ad-block resistance

Custom Loader

Custom-loaded GTM scripts

Your gtm.js and analytics scripts load through a custom path on YOUR domain. uBlock, AdBlock Plus, Brave can’t identify them as trackers.

Attribution

Click ID Restorer

Click ID restoration

fbclid / gclid / ttclid / wbraid recovered from the URL and persisted server-side. Multi-redirect funnels stop dropping attribution. Safari user IDs restored.

Profit signal

POAS Data Feed

POAS — Profit on Ad Spend

Send actual profit data (not revenue) to Meta / Google. Smart Bidding optimizes for the metric that matters: net margin, not gross revenue.

Identity

User ID

Cross-session User ID

Stable userID generated server-side from IP + UA + SSL fingerprint. Stitches anonymous → known → returning visitors across 400 days.

Audience signal

GEO Headers

GeoIP enrichment

Country, region, city, postal code passed to Meta / Google CAPI from your server — without exposing the raw user IP to the browser.

Compliance

Anonymizer

PII hashing by default

Email, phone, name, address are SHA-256 hashed on your server before they leave for Meta or Google. Zero raw PII in transit.

Quality filtering

Bot Detection

Bot traffic detection

Bot/scraper traffic identified at the gateway and blocked from polluting your audiences. Smart Bidding optimizes against humans, not bots.

Reliability

Dedup logic

Browser ↔ server dedup

Deterministic event_id and event_time so Meta / Google never double-count. Your reported ROAS stops contradicting Stripe.

Reputation

Dedicated IP

Dedicated outbound IP

Your sGTM gets a dedicated static IP for outgoing CAPI requests. Better deliverability to Meta, Google, TikTok — no shared-IP noise.

Residency

Multi-region

EU / US region routing

GDPR-conscious stores route their CAPI traffic through EU regions (Stape EU or self-hosted GCR europe-west). No US data hop.

Data warehouse

BigQuery export

BigQuery + Looker dashboard

Server logs + GA4 raw events streamed to BigQuery. Looker Studio dashboard branded for your team. Premium tier.

We’re official Stape Pro partners — every Power-Up above is enabled and configured for you. Or we self-host the equivalent on your Cloud Run / GKE if your traffic justifies the cost crossover. You pick.

Live data flow

What your stack is doing —right now

Every conversion fires through your subdomain, gets enriched with hashed identity params, deduped against the browser pixel, then forwarded to Meta CAPI, Google EC, TikTok Events API and Microsoft UET in parallel.

You see this stream live in your sGTM debug console — not a SaaS dashboard you rent. It’s your data, on your server, on your subdomain.

What you get

The checklist

Item 01

Counting setting reviewed per action

Every versus one. Wrong on lead-gen accounts more often than not.

Item 02

Exactly one primary action per objective

Check the conversion actions list, not your memory of it.

Item 03

Values sent per conversion

Not a fixed placeholder.

Item 04

Attribution window recorded

So platform disagreements can be explained rather than argued about.

Item 05

No action left inactive

Google flags inactivity 30 days late, after a month of blind bidding.

The honest math

Three ways to fix your tracking. One of them makes sense.

Option 1

Hire a senior tracking engineer

$15K–$25Kin dev cost

or 2–4 weeks of senior FTE time

  • 2–4 weeks before anything ships
  • Misses iOS / Safari / dedup edge cases
  • No EMQ guarantee — it’s “done” when they say so
  • Pixel debugging is not their day job

Option 2

Triple Whale / Hyros / Northbeam

$300–$2,000/month forever

$18K–$120K over 5 years

  • You rent a dashboard — they own your data
  • Cancel and you lose attribution overnight
  • Per-event / per-visitor pricing surprises
  • Still doesn’t fix your underlying tracking
Recommended

Option 3 — us

Done-for-you 1st-party server-side

$400–$1,800one-time

pay once · own the stack forever

  • Live in 2–4 days · accurate data within 7
  • iOS / Safari / dedup all handled by default
  • Meta EMQ 8+ guaranteed in writing
  • You own everything — server, container, runbook

We’re upfront: if you have a senior in-house dev with capacity and 4 weeks, hiring is fine. If you spend $1M+/yr on ads and want a SaaS dashboard layered on top, Triple Whale works. For most paid-ad advertisers between, we’re the math that makes sense.

Pricing

Pick the package that fits your ad spend

Fixed-fee, no surprises. If your ad spend is meaningful,server-side tracking is what we recommend— it’s the only setup that survives iOS, Safari ITP and ad blockers.

“I’ll personally walk through your tracking on the call.No SDR.No sales pitch.”

I’ve spent 8 years rebuilding tracking for DTC brands, SaaS founders, agencies, and one thing I’ve learned: most tracking problems aren’t technical — they’re trust problems. You don’t know who to believe. Your current vendor swears it’s fine. Meta’s reports look great. Stripe says otherwise.

On our call, I’ll personally show you exactly what’s leaking, exactly what it would cost to recover, and whether you should hire us at all. If your current setup is genuinely fine, I’ll tell you. If a $400 browser-side fix is enough, I’ll say so. No upsell pressure.

Book the call. Worst case, you walk away with a free 47-point audit checklist. Best case, we deliver your 1st-party server-side stack in 2–4 days and your data is fully accurate within 7 days.

Architecture

The settings that change your numbers

Each of these is free to change and each one moves your reported conversions. Google's own documentation is the authority on current options.

  1. Step 1

    Counting: every vs one

    Every counts each conversion; one counts a single conversion per click. Leads want one; ecommerce wants every.

  2. Step 2

    Primary vs secondary

    Primary drives Smart Bidding. Secondary reports only. Several primaries is the most common cause of odd bidding.

  3. Step 3

    Conversion value

    Real revenue where you can get it. A flat value teaches bidding that every conversion is identical.

  4. Step 4

    Click-through attribution window

    Configurable. Different windows across platforms are most of why the platforms disagree.

  5. Step 5

    Conversion action status

    An inactive action stops feeding bidding. Google's notice arrives 30 days after the last hit.

  6. Step 6

    Enhanced Conversions

    Improves matching on an existing web conversion. Verify it in the diagnostics report, not by the toggle.

Diagnostic sequence

Common mistakes and how to validate each

Ordered by how often we find them. Each one has a specific check rather than a general instruction to be careful.

  1. 1

    Counting left at the default

    Open the action and read the setting. On lead forms it's the single most common inflation source.

  2. 2

    Multiple primaries

    List your actions and count how many are primary. More than one per objective is a problem.

  3. 3

    Values missing entirely

    Check whether a value arrives on a live conversion. Many accounts send none at all.

  4. 4

    An action inactive for weeks

    Check the last-received date on every action, not just the main one.

  5. 5

    Native and imported GA4 conversions for the same thing

    Both feeding one action double-counts. Check the source of each.

Source-of-truth validation

How to prove your implementation is right

Against your own records and a live payload, not against a preview screen.

Source of truthyour own order or CRM records, matched per record
  • Counting and primary status read and documented per action.
  • Values confirmed arriving on a live conversion.
  • Last-received date checked on every action.
  • Conversion count reconciled against your own records for a closed month.
  • Checked on a live conversion, not in preview mode.
  • Reconciled over a fully closed window, matched per record.
  • Re-checked 30 days later.

Straight talk

What this reference deliberately leaves out

Stated openly, because a reference that's silent about its own gaps is the dangerous kind.

  • Google's conversion action settings change and new options appear. Verify against current documentation before relying on any of this for a build.
  • This covers settings rather than the tag implementation, which is a separate problem with separate failures.
  • Attribution model selection interacts with all of this and is covered separately.
  • Vendor documentation is the authority, not this page. Where the two disagree, the vendor is right and we'd like to know so we can correct it.
  • Parameter names and behaviour change. Anything here is accurate as we last verified it; verify against the current documentation before you rely on it for a build.

Got questions?

The honestanswers.

No buzzwords, no upsell. If we don’t know, we say so.

01Should counting be every or one?

One for lead generation — otherwise repeat submitters inflate the count. Every for ecommerce, where a second purchase is a second sale.

02How many primary actions should I have?

One per campaign objective. Several competing primaries is among the most common causes of bidding that behaves strangely.

03Does the attribution window affect bidding?

It affects what gets attributed and therefore what bidding learns from. Set it deliberately and write down what you chose.

04Why did Google tell me my action was inactive?

It flags 30 days after the last recorded hit. By then a month of budget has run against a missing signal, which is why last-received dates are worth checking monthly.

Still have questions?Book a 30-min call— bring them all.
