A HubSpot attribution audit that tells you exactly where the data leaks

The Attribution Audit is a fixed-scope review of how a click on your ad becomes a contact, a deal and a conversion back in Google Ads, Meta and LinkedIn. I test every hop, find where source data gets lost, and hand you a written report with each leak ranked by cost and a plan to fix it. It starts at $2,000.

Who it is for

This is for you if

→B2B companies running paid campaigns on Google Ads, LinkedIn or Meta, with HubSpot as the CRM
→Teams that see a large share of contacts with Direct or Offline as their Original Source and do not trust the reports
→New marketing leaders who need to know what the data can and cannot support before moving budget
→Companies about to buy an attribution tool who want to know if their inputs are clean first

Symptoms

Signs you need this

→A large share of new contacts land in Direct traffic. See why HubSpot shows so much Direct traffic.
→GA4 and HubSpot report different lead counts for the same period. See GA4 vs HubSpot mismatch.
→Form submissions arrive without UTMs. See HubSpot form UTMs missing.
→Google Ads optimizes on form fills because it never sees which leads became pipeline. See offline conversions missing.
→Nobody on the team can explain how a contact gets its Original Source.

What I do

What the work covers

Capture test on every entry point

Tagged test visits through each paid channel, landing page template and form type, including embedded forms, booking tools and your app domain.

CRM source review

How Original Source, Latest Source and your custom source fields are populated, overwritten and reported on in HubSpot.

Ad platform feedback check

Whether Google Ads, Meta and LinkedIn receive the conversions that matter, with the right click IDs and match keys.

Consent and browser loss estimate

How your consent banner, Consent Mode setup, Safari and ad blockers affect what each tool records.

Written findings, ranked

Every leak with evidence, likely impact and effort to fix, so you can decide what is worth fixing first.

Fix plan with fixed prices

A scoped plan for each fix. You can hand it to your own team or have me do it as The Fix.

How it works

Three steps

Access and a short brief

Read access to HubSpot, GTM, GA4 and your ad accounts, plus 30 minutes on how your funnel works.

I test and trace

Test visits and submissions through every path, then I follow each record into HubSpot and the ad platforms.

Report and walkthrough

You get the written report and a call to go through it. The fix plan is yours either way.

Scope and timeline

Typical scope

Price: From $2,000, fixed before work starts
Turnaround: 5 business days from confirmed access
Your time: About 1 hour: access setup, a short brief and the walkthrough call
Access needed: HubSpot, GTM, GA4, Google Ads, Meta and LinkedIn Ads (read-only is enough)

Quoted above $2,000 when any of these apply: more than one domain, brand or HubSpot portal; more than 3 ad platforms; a custom integration or middleware (Zapier, custom code) in the lead path; an existing server-side GTM container to audit; or app/product domain tracking. Scope and price are always agreed before starting.

What you get

At the end you have

→A clear list of where attribution breaks, with evidence for each item
→An estimate of which leaks cost the most, so budget decisions stop waiting on "better data"
→A fixed-price plan you can approve, hand to your team, or ignore
→Read-only work: nothing changes in your stack during the audit

Architecture

How the pieces connect

01
Ad click
UTMs and click IDs (gclid, li_fat_id, fbclid)
02
Website
Tracking code, consent, cross-domain hops
03
Form
Embed type, hidden fields, hutk cookie
04
HubSpot
Original Source, lifecycle stages, deals
05
Ad platforms
Offline conversions and Conversions APIs

The audit follows one lead through every hop. A leak at any step shows up later as Direct traffic, missing UTMs or an ad platform that optimizes on the wrong signal.

Case study

Where this came from

B2B company running paid acquisition, HubSpot as CRM

HubSpot showed the wrong traffic sources. The real problem was four layers deep.

A B2B team asked why HubSpot showed the wrong traffic sources. The answer led to a broken offline conversion feed, cross-domain breaks and a custom integration that had to be rewritten.

Questions

Attribution Audit: common questions

Because it is real work: test traffic through every channel and form, then tracing each record through HubSpot and the ad platforms. A free call can guess at the cause. The audit proves it, and the report is useful even if you never hire me for the fix.

No. The audit is read-only. Changes happen in The Fix, after you have seen the findings and agreed a price.

Then you get a documented baseline proving your data is sound. That is a deliverable in itself, worth having before you move budget or buy an attribution tool. There is no refund for a clean result.

Yes. The full audit fee is credited against The Fix if you book it within 30 days of the report.

Most marketing ops people are experts in HubSpot workflows, campaigns and reporting, not in tracking code, server-side tagging or ad platform Conversion APIs. If your marketing ops person is the one asking why HubSpot shows so much Direct traffic, the problem sits outside their usual scope.
