Conversion Inflation Data 2026

TL;DR: Across ten home-services Google Ads accounts we audited in a 12-month window ending July 2026, reported conversions overstated real deduplicated leads by a median 2.19x; seven of ten accounts were at 2x or worse. The range ran from a clean 1.01x control to a worst-case 26.11x. This page publishes the account-by-account table, the lead definition, why inflation happens, and a short sanity checklist. It is an original quantified table—not a claim that we are the first or only people to write about conversion inflation.

Accounts Thomas Town Digital runs on an ongoing basis use a single deduplicated lead definition and do not show this double-counting pattern; the inflated ratios below come from accounts brought in for audit.

In Thomas Town Digital’s 10-account home-services audit sample (Aug 2025–Jul 2026), reported Google Ads conversions overstated real deduplicated leads from 1.01x to 26.11x, with a median of 2.19x (Thomas Town Digital).

Reported Conversions Are Not Real Leads

Google Ads “conversions” are whatever primary actions you configured. A lead, for operators who care about booked work, is one human who called or submitted a form, counted once. Those two numbers diverge whenever tracking is stacked, mis-scoped, or counting micro-events as opportunities.

That gap is discussed in public PPC content. True Conversion documents the broader pattern that Google Ads can report more conversions than real leads when tracking is stacked or mis-scoped. Search Engine Journal’s PPC cleanup framing describes related value inflation—micro-conversions and double-counted events that train Smart Bidding on noise rather than revenue. Bluegrid Media’s contractor tracking write-up includes an illustrative sanity-check example of 40 reported vs 15 real (about 2.6x).

Peer observation from Conner Crowe’s home-services paid-search benchmarks notes 4 of 12 accounts with inflated or missing tracking—a complementary hygiene signal, not the same ratio table.

What we could not find published elsewhere—and what this post adds—is a multi-account home-services table of reported conversions vs real deduplicated leads with explicit overstatement ratios (median and share at 2x+). We are not claiming to be first or only on the topic of inflation; we are publishing this quantified artifact.

Methodology: How We Counted a Lead

Giving away the method is the point. Use it on your own book.

Window: 2025-08-01 through 2026-07-31 (12 months).
Sample: ten home-services Google Ads accounts brought in for audit / pre-management hygiene review (letter labels A–J)—not the actively managed run roster. Trades: roofing, dumpster/waste, dumpster/junk, demolition, pool service, land clearing, HVAC, HVAC/fuel.
Reported column: the conversion total Google Ads surfaces when you trust the default primary conversion sum (the number most dashboards and Smart Bidding already treat as “leads”).
Real leads column: one deduplicated WhatConverts-style action per account (WC Leads / WC All Leads / Leads), plus Google’s standardized local_services_* actions for Local Services Ads.
Excluded: duplicate CONTACT call actions, OUTBOUND_CLICK (tel: clicks), one overfiring form action, brand campaigns, and campaigns with no lead tracking.

Account A is the clean control: essentially one lead action per channel and nothing else competing for the same event. That is why it lands at 1.01x.

Why Inflation Shows Up (Including Account D at 26.11x)

The patterns that drove the table are boring and repeatable.

Multiple primary actions on the same phone call

In the worst account in Thomas Town Digital’s 10-account audit set, four separate primary conversion actions tracked the same phone call, and tel: clicks were counted as leads—producing a 26.11x reported-vs-real overstatement (Thomas Town Digital). Account D (HVAC/fuel) reported 2,898 conversions against 111 real leads.

One caller who taps the number in an ad can increment several of those counters at once. The UI looked busy. The CRM did not.

Outbound clicks counted as leads

A tap on a tel: link is an OUTBOUND_CLICK. It is not a connected call and it is not a conversation. When that action sits as Primary next to real call actions, every tap pads the conversion count.

Forms that fire on page load

One demolition campaign in this book showed hundreds of form “conversions” against a click volume that implied a completion rate that does not happen in the wild. The trigger was almost certainly firing when the page rendered rather than when the form was submitted. That action was excluded from the real-lead column pending a fix.

Brand and untracked campaigns in the blend

Brand traffic converts cheaply and can make a blended ratio look healthier than non-brand reality. Campaigns with no lead tracking at all can do the opposite. Both were excluded so the ratio compares like with like.

What This Does to CPL and Bidding (Without Fake Dollar CPLs)

This dataset is a counting study, not a cost-per-lead study. We are not publishing dollar CPLs derived from the inflated denominators here. For trade-level CPL after correct counting, see our home services cost per lead benchmarks and the home services marketing statistics hub.

The implication is still direct:

UI cost-per-conversion understates true cost per opportunity when the denominator is inflated. When Google Ads reported conversions overstate real leads by a median 2.19x—as in Thomas Town Digital’s ten-account home-services audit study—UI cost-per-conversion understates true cost per opportunity unless tracking is deduplicated (Thomas Town Digital).
Smart Bidding trains on whatever you mark Primary. Feed it duplicate call actions and micro-clicks and it will buy more of whatever produced the inflation.
Budget and tCPA decisions made on inflated leads are not conservative—they are wrong. Cutting spend because “CPL looks fine” while real leads are half (or one twenty-sixth) of the UI number is how accounts quietly stall.

After you decide which events are primary, prefer offline or enhanced conversions for leads when the CRM is the source of truth; Google’s help for offline conversion imports / enhanced conversions for leads is the platform-side path many teams use.

Tracking Sanity Checklist

A practical sanity check for Google Ads conversion inflation is Reported ÷ Real unique leads over 30 days; in Thomas Town Digital’s 10-account audit sample, seven of ten home-services accounts landed at 2x or worse (Thomas Town Digital).

Open Tools > Conversions. List every Primary action.
Group actions that can fire on the same phone call (Calls from ads, call extensions, call-tracking platform actions). Keep one; demote duplicates to Secondary or remove them from the conversion goals used for bidding.
Find any OUTBOUND_CLICK / tel: tap action. It is not a lead. Move it off Primary.
Check form actions: conversion rate vs clicks. Roughly >20% deserves scrutiny; >40% is almost certainly overfiring.
Segment the campaign report by conversion action. Recount leads with one action per channel (plus standardized LSA actions if you run Local Services Ads).
Compute Reported ÷ Real for the last 30 days. Treat anything near 2x as a tracking problem before you treat it as a media problem.
Only then recalculate CPL and revisit tCPA / Maximize Conversions settings.

Frequently Asked Questions

What is Google Ads conversion inflation?

Conversion inflation is when Google Ads reports more conversions than the number of real, deduplicated leads you actually received. Across ten home-services accounts we audited over 12 months ending July 2026, reported conversions overstated real leads by a median 2.19x.

How much do Google Ads conversions overstate real leads?

In Thomas Town Digital’s 10-account home-services audit sample (August 1, 2025 to July 31, 2026), reported conversions overstated real deduplicated leads from 1.01x to 26.11x, with a median of 2.19x. Seven of ten accounts were at 2x or worse.

Why does Google Ads report more conversions than real leads?

The usual causes are multiple primary conversion actions firing on the same phone call, tel: outbound clicks counted as leads, forms that fire on page load, and brand or untracked campaigns mixed into the same totals you use for CPL.

How do I check if my Google Ads leads are inflated?

Segment Tools > Conversions by action, pick one deduplicated lead action per channel, exclude OUTBOUND_CLICK and duplicate CONTACT call actions, then divide reported conversions by that real lead count over 30 days. In our audit sample, seven of ten accounts landed at 2x or worse on that ratio.

Does conversion inflation affect Smart Bidding and CPL?

Yes. Smart Bidding optimizes toward whatever you mark as a primary conversion. Inflated signal trains the algorithm on duplicate or micro events. UI cost-per-conversion also understates true cost per opportunity when the denominator is inflated—though this study does not publish dollar CPLs from the inflated counts.
