Google Ads Audit: AI Google Ads Account Audit and PPC Audit Tool

A basic Google Ads audit for a small local account typically costs $400 to $800 in 2026. A standard audit for a mid-size advertiser, covering search terms, ad testing history, and audience targeting in depth, runs $750 to $2,500. Enterprise accounts spending $50,000 a month or more, with large shopping feeds and multi-location targeting, pay $2,500 to $5,000 and up. Independent PPC consultants who audit hourly bill roughly $75 to $250 per hour.

Free audits exist, and they are almost always automated script-based reviews built to funnel you into a management contract. They are useful for a fast sanity check and thin on anything that requires judgment. The more useful comparison is not audit price against audit price, it is audit price against what the audit finds: on a $10,000 monthly budget with 30% waste, the leak is $3,000 a month, which dwarfs the cost of any audit on this list. See how the ongoing management side prices out on our Google Ads management page.

Run a full structured audit at least quarterly. Accounts spending roughly $5,000 a month or more should add a lighter monthly review on top of the deep quarterly one. Search terms and negative keywords need attention weekly on any active account, regardless of audit cadence, because that is where waste accumulates fastest. Audit immediately after any major change too: a new bid strategy, a site migration, a tracking update, or a new campaign type.

The quarterly rhythm is a compromise with human availability, not an ideal. Nothing about an ad account waits three months to break. Budgets shift, competitors enter the auction, a landing page 404s, a conversion tag stops firing after a deploy. Continuous checking is the actual answer, which is what AdBot is built to do and what our AI PPC software page covers in more depth. If your spend is split across channels, the Meta side needs its own pass on pixel setup, event match quality, and creative fatigue: our Facebook ads audit page covers what that review checks, and the PPC audit page covers reviewing both together.

A complete audit covers ten areas in this order: conversion tracking accuracy, account and campaign structure, keywords and match types, negative keyword coverage, the search terms report sorted by cost, Quality Score on your top-spending keywords, bid strategy status and targets, ad copy and responsive search ad asset performance, landing page relevance and speed, and budget allocation against results. Performance Max deserves its own pass, checking brand exclusions, account-level negatives, and asset group discipline.

Two health checks tie it together. Compare each campaign's share of spend to its share of conversions to find the budget that is in the wrong place, and check impression share lost to budget against impression share lost to rank to know whether you are constrained by money or by relevance. For context on the numbers an audit should be measured against, 2026 benchmarks put a healthy search CTR at 3% to 5%, conversion rate at 3% to 5%, Quality Score at 5 to 7, and impression share at 60% to 80%. Run your own targets through the ROAS calculator and the CPA calculator before you judge any of them.

Performance Max now takes roughly 34% of total Google Ads budgets, and it is the part of an account where an audit most often changes the headline numbers, because there are no bids or keywords to review and almost everyone leaves the few available settings on their defaults. Four findings come up again and again: brand exclusions switched off, so PMax is buying conversions from people already searching your company name; a single asset group carrying every product instead of one per line or margin tier; assets rated Low sitting in place and narrowing how often the group serves at all; and no account-level negative keyword list fencing the campaign in.

The most valuable check is the one that compares PMax against the rest of the account rather than reading its own dashboard. If PMax conversions rose while total account conversions stayed flat, nothing was gained and budget simply moved between line items, which is why a PMax review has to be done at account level. Our Performance Max optimization page covers the fixes in order, and the guide to diagnosing PMax cannibalization shows the exact reports to pull.

Google Ads audit software exists in three fairly different forms, and the labels get used interchangeably even though the products are not comparable. Free graders score an account in a few minutes against a fixed rule set and produce a report; they are lead magnets for agencies and are honest about roughly the top layer of problems. Adwords audit software sold on subscription, the Optmyzr and Adalysis end of the market, runs far deeper checks continuously and is built for a specialist who will act on the output. Agent-style software audits and then applies the fixes itself, which is the category AdBot sits in.

What none of them replace is business context. Audit software can tell you a campaign spends $3,000 a month and produces four conversions. It cannot tell you that two of those four were your largest customers of the year, or that the product line is being discontinued in October. Those judgments belong to a person who knows the business, which is the honest case for paying a Google Ads consultant for a few hours even if software handles the recurring review.

The practical split most advertisers land on: software for frequency, a human for direction. Waste accumulates daily and needs catching daily, which no hourly engagement can economically cover. Strategy changes a few times a year. Buying a $2,000 manual audit to solve a daily problem is the mismatch that makes so many audits feel like wasted money, and it is why the same findings reappear in the next one.
