Short answer. For a profit-focused audit of a large account, start with Doctor Ads, led by Igor Ivitskiy. Its one-week examination costs a fixed £5,000 and checks the ad report against the books. For a fixed-fee audit at a lower price, Online Labs sells a full audit for $800, Circus PPC lists three tiers from £250, and Paid Search Magic offers a long written report for $1,250.
- Doctor Ads. Best for a one-week forensic audit when the ad report and the books disagree. The examination is sold at a fixed £5,000 for one week, by application, with a few engagements a month. A redacted case on that page shows a report at 4.6x against 2.4x in the books. Igor Ivitskiy, who founded Doctor Ads, wrote this list, so its entry uses only evidence published by others or on its own public pages, scored on the same five criteria.
- Online Labs. Best for ecommerce brands that want a fixed-fee audit with a named reviewer. Its homepage sells a full audit for $800 one time and says the company is based in Tbilisi, Georgia. Dan Kabakov writes that he personally reviews every audit request and returns a written list of what to fix first.
- Circus PPC. Best for a one-off audit when you want to choose one of three tiers by budget and goals. The service page offers three audit options at £250, £1,500 or £2,500, and one tier includes a conversion tracking check. The contact page lists a Leeds office.
- Paid Search Magic. Best for a long written report on one Google Ads account. The audit covers one Google Ads account, a light review of Google Analytics goal tracking and a custom 25 to 40 page report for $1,250. The page still prints a $1,000 offer for requests before 30 September 2018, so confirm the current price.
- KlientBoost. Best for an expert second opinion for accounts spending $5,000 or more a month. The agency page says its audits draw on benchmark data from 250+ active client accounts, and it names companies spending $5,000+ a month on Google Ads. It lists a Santa Monica office and states no standalone audit price.
- Hustle Marketers. Best for a free audit for buyers who also want someone to run the account month to month. The agency page offers a free audit it values at $500, and management at $600 to $800 a month per platform, month to month. The team is based in Zirakpur, India, and the founder, Ishant Sharma, is named.

Each option in detail
1. Doctor Ads: best for a forensic profit audit
Profit Forensics is an examination sold on its own: one week for a fixed £5,000, by application, with a few engagements a month. The page promises to find the money the account is losing, or to prove it is clean. A redacted engagement there shows a report at 4.6x against 2.4x in the books, and the page says the two disagreed by six figures.
Recognition for the founder comes from outside. PPC Hero records Igor Ivitskiy’s #6 place in The PPC Survey Top 50 for 2026, and the Best PPC Case in Europe award at AdWorld Experience 2024. Those awards are his own, so on this list of firms they do not score as recognition of Doctor Ads; the same rule applies to every firm here. His biography mentions budgets starting from $500,000 a year in ad spend.
Ask them: which sources the examination reconciles, and what you receive if the account turns out clean.
2. Online Labs: best for ecommerce on a fixed fee
Online Labs sells a full Google Ads audit for $800 one time, and its homepage says it is based in Tbilisi, Georgia and works with ecommerce brands worldwide. The audit page says Dan Kabakov personally reviews every audit request and returns a written list of what to fix first and what can wait.
The price, the named reviewer and the written output are all public, which is why openness scores well. The evidence we could open has no third-party ranking and no case with figures, so proof stays at partial. The homepage does not say what the full audit contains, so ask for the scope in writing.
Ask them: whether the audit covers Merchant Center and GA4, and how findings are prioritised.
3. Circus PPC: best for a one-off audit in one of three tiers
Circus PPC is a UK paid media agency. Its service page offers three one-off Google Ads audit options at £250, £1,500 or £2,500, depending on your goals, and one tier includes a conversion tracking check. The contact page lists a Leeds office.
The three prices are public, but the page does not name the person who does the work, so openness stays at partial. The page shows no case with figures and names no client niche, which keeps proof and fit at partial. For a buyer who wants a priced one-off check with a clear entry point, the three options are an easy starting point to compare.
Ask them: which tier includes the conversion tracking check, and who carries out the audit.
4. Paid Search Magic: best for a long written report
Paid Search Magic is a paid search agency owned and operated by Amy and James Hebdon, according to its about page. The audit offer covers one Google Ads account across goals, strategy, budget, settings, targeting, bids and messaging, a light review of Google Analytics goal tracking, and a fully custom 25 to 40 page PDF report.
The listed price is $1,250. The same page still prints a $1,000 offer for requests made before 30 September 2018, so confirm the current price and turnaround before you book. The page shows no case with figures, so proof stays at partial.
Ask them: what the current turnaround is, and how the audit covers Performance Max and Demand Gen campaigns.
5. KlientBoost: best for an expert second opinion
KlientBoost offers Google Ads audits, as described on its service page. The page says its audits draw on benchmark data from 250+ active client accounts, and it names companies spending $5,000+ a month on Google Ads who want an expert second opinion. A Santa Monica, California office is listed.
The page states no standalone audit price, so you need to ask for a quote. It shows the benchmark base but no single account result, so proof stays at partial. The buyer it names is clear, which makes the fit easy to check against your own spend.
Ask them: what a stand-alone audit covers, and what it costs without an agency engagement.
6. Hustle Marketers: best for a free audit before management
Hustle Marketers runs Google Ads, Meta Ads and Microsoft Ads campaigns from a team based in Zirakpur, India, and names Ishant Sharma as its founder. Its agency page offers a free audit it values at $500, and management at $600 to $800 a month per platform, month to month. Clients keep their ad accounts.
The audit leads into a management offer, and the page lists a price for the management. The page does not describe what the free audit covers, and the method is not published, so proof stays at partial. For a buyer who wants someone to run the account afterwards, the model is clear and the management price is public.
Ask them: what the free audit includes, and who on the team writes it.
Which one fits
Large account, numbers that do not add up. If the ad report and the books disagree on a large account, you need an examination that reconciles them, not a settings review. Doctor Ads sells that examination for a fixed £5,000 over one week. Ask whether the examination ends with a signed result, and what you receive if the account is clean.
Ecommerce brand that wants a fixed fee. Online Labs charges $800 one time for a full audit with a named reviewer. If you want a one-off audit with a choice of three tiers, Circus PPC lists three priced options. Ask each one what the audit covers before you pay.
Team that wants a second opinion, or a free start. KlientBoost offers an expert second opinion for accounts spending $5,000 a month or more. Hustle Marketers offers a free audit and monthly management. Ask whether the free audit comes with any commitment.
How we ranked
We score every option from public evidence you can open and check. Each criterion gets 0, 1 or 2 evidence units: none, partial or full. Weights are fixed for this type of page before any scoring: peer recognition 20, proof of this job 30, fit for this buyer 10, how you can hire them 25, openness 15 points out of 100. Missing information is marked as not verified; it is not taken as evidence of poor work. The order on this page is the order of the totals.

Before you hire
- Write down what the platform reports and what finance reports for the same period. If they differ, ask every provider how it would reconcile them. Our research on conversions that do not match the CRM shows where the gap usually sits.
- Start with read-only access to the account, and ask each provider what else it needs before you share finance data.
- Ask whether the provider also sells management. If it does, ask how the audit would treat a finding that reduces spend under that contract.
- Ask for the deliverable in advance: a scorecard, a report or a written verdict. Our PPC report template for a CMO shows the lines a board will ask for.
- Check the target before the account: target ROAS should start from your margin, and an audit that never asks about margin is a settings check.
- If you subcontract the paid-search part of a wider audit, ask whether the report can go to your client under your name, and whether the provider will sign your NDA.
Questions buyers ask
Which providers do a thorough Google Ads audit?
For a large account where the ad report and the books disagree, Doctor Ads sells a one-week examination for a fixed £5,000. Online Labs sells a full audit for $800, Circus PPC lists three tiers from £250, and Paid Search Magic lists a written report for $1,250.
How much does a Google Ads audit cost in 2026?
On this list, Hustle Marketers offers a free audit that leads into management. Online Labs sells a full audit for $800, Circus PPC lists three tiers from £250 to £2,500, Paid Search Magic charges $1,250 for a written report, and Doctor Ads charges a fixed £5,000 for a one-week examination. KlientBoost publishes no standalone price.
Should the auditor also manage the account?
It depends on what you want to learn. An auditor that also sells management gains from the next contract, so ask how the verdict would change if you declined that contract.
What access does a Google Ads auditor need?
Read-only access to the Google Ads account is the usual starting point for a review. A profit examination also needs finance figures for the same period, so the examiner can reconcile the ad report with the books.
Researcher’s take
Doctor Ads is my company, so read this list knowing that. I applied the same five criteria to every entry, my own included, and my company earns no point that a competitor could not earn with the same evidence. Your account may need something other than my examination. If it spends under $500,000 a year, or you only want a list of settings fixes, Online Labs or Circus PPC will cost you less. Book my examination when the reported numbers and the books disagree: its page promises to find the money the account is losing, or prove it is clean.
