This piece breaks down the real costs of PPC audits at different levels, what you can expect to find, and a framework for estimating the ROI before you commit.
What PPC Audits Actually Cost
The range is wide because "PPC audit" can mean very different things. Here's a realistic breakdown:
- Free automated tools ($0): Run an automated check against your account. You get a score and a list of findings. Good for a quick health check. Limited depth.
- Free agency audits ($0, but with a pitch): An agency reviews your account for free as a way to win your business. Quality varies hugely. Some are thorough, others are designed to make your account look bad so you'll hire them.
- Freelancer audits ($300-1,000): A PPC specialist spends a few hours reviewing your account and delivers a report. Good value for small to mid-size accounts. Quality depends entirely on the individual.
- Agency audits ($1,000-3,000): A full audit from a reputable PPC agency. Typically includes conversion tracking verification, competitive analysis, and a prioritized action plan. Best for accounts spending $10K+/month.
- Enterprise audits ($3,000-10,000+): For large, complex accounts with multiple markets, languages, or business units. Includes cross-platform analysis and executive-level reporting.
How to Estimate the ROI Before You Pay
Before committing to a paid audit, you can estimate potential ROI with some quick math. Here's a framework:
Step 1: Estimate your waste percentage. If you haven't had an audit in 6+ months and you're running broad match keywords without negative keyword lists, you're probably wasting at least 20% of spend. If you're more actively managed, 10-15% is a reasonable estimate.
Step 2: Calculate the monthly waste. Monthly spend x waste percentage = monthly wasted spend. So $15K/month x 20% = $3,000/month in waste.
Step 3: Estimate recoverable waste. You probably can't fix 100% of waste, but fixing 60-70% is realistic. So $3,000 x 65% = $1,950/month in recoverable savings.
Step 4: Compare to audit cost. If the audit costs $1,500 and it saves you $1,950/month, it pays for itself in less than a month. Over 12 months, that's a 15x return.
When a Free Audit Is Enough
You probably don't need to pay for an audit if:
- You're spending under $5K/month
- You manage the account yourself and just want a second opinion
- Your account has a simple structure (fewer than 10 campaigns)
- You're mainly looking for obvious issues like missing extensions or negative keywords
In these cases, a free audit tool or a DIY 30-minute audit will catch the major issues. The value of a paid audit comes from depth and context that free tools can't provide.
When You Should Pay for an Audit
A paid audit is worth considering when:
- You're spending $10K+/month and even a 10% improvement saves more than the audit cost
- Performance has been declining and you can't figure out why
- You suspect tracking issues but lack the technical skills to verify
- You're evaluating your current agency and want an independent opinion
- You're about to scale spend significantly and want to make sure the foundation is solid
The accounts that get the most value from paid audits are those spending $10K-100K/month with moderate complexity. Below that, the savings might not justify the cost. Above that, you probably need ongoing management more than a one-time audit.
How to Choose an Auditor
If you decide a paid audit makes sense, here's what to look for:
- Platform certification: Google Ads certification is baseline. Look for Premier Partner status or equivalent experience.
- Industry experience: An auditor who understands your industry can spot issues that a generalist might miss.
- Sample report: Ask to see a sample audit report. If it's vague and full of generic recommendations, that's what you'll get.
- Deliverable clarity: Before paying, know exactly what you'll receive. Number of checks, turnaround time, format of the report, and whether the audit includes a walkthrough call.
Be cautious about "free audits" from agencies that are clearly designed to sell you management services. They tend to emphasize problems (some of which may not actually be problems) and downplay what's working. An independent paid audit is more likely to give you an honest assessment.
The Bottom Line on Audit ROI
For most accounts spending $10K+/month, a professional PPC audit pays for itself within 1-2 months through reduced waste and better budget allocation. The most common findings (tracking errors, search term waste, bid mismatches) each represent 10-25% of affected spend.
But you don't have to start with a paid audit. Our free audit runs 54 automated checks and gives you a scored breakdown. If the free version surfaces enough issues that you're wondering what a deeper review might find, that's your signal.
Frequently Asked Questions
Free audits catch surface-level issues effectively. Paid audits add depth: cross-system verification, competitive context, business-specific recommendations, and prioritized action plans. For small accounts, free is often sufficient. For larger accounts, the depth of a paid audit usually justifies the cost.
Once a year for most accounts. If you're spending over $50K/month or in a rapidly changing market, twice a year is reasonable. Between audits, run free automated checks quarterly to catch obvious issues.
They can, but there's an obvious conflict of interest. An agency is unlikely to report that their own campaign structure is wrong. Independent audits from a third party give you a more honest assessment. Some businesses use this as a way to keep their agency accountable.
