How to Run a PPC Audit (and Fix What’s Wasting Your Budget)

Most PPC accounts fail because no one is checking the details, not because of a bad overall strategy.

I’ve audited accounts spending a few hundred dollars a month and accounts spending six figures. The pattern is the same. Tracking is off, campaigns are messy, and keywords are fighting each other. Budget is leaking in places no one is looking. A PPC audit is how you find that waste and turn it into performance.

Your Data Might Be Wrong

Before you touch anything in your Google Ads or paid search campaigns, check your conversion tracking. If your data is off, everything else you optimize will be wrong.

Look for:

-Duplicate conversions or inflated conversion counts

-Mismatch between Google Ads and analytics platforms

-Conversion actions firing more than once per user

-Missing or underreported revenue values

In audits, tracking issues show up in a large percentage of accounts and can completely distort CPA and ROAS. If this step is skipped, the rest of the audit doesn’t matter.

Fix Your Campaign Structure

Campaign structure controls how your budget is spent; despite what you might think, it’s way more than cosmetic.

A strong PPC account structure should:

-Separate brand, non-brand, and competitor campaigns

-Group tightly themed keywords into focused ad groups

-Align campaigns with clear goals like lead generation or sales

-Avoid overlap that causes internal competition

When campaigns are poorly structured, you end up bidding against yourself and inflating CPC. If your structure is messy, fix it first. Optimization comes later.

Audit Your Keywords Like Your Budget Depends On It (Because It Does)

Keywords are where most wasted ad spend lives. Look at your search terms report and ask:

-Which keywords are driving conversions?

-Which ones are spending with no return?

-Where are irrelevant queries slipping through?

Then take action:

-Aggressively add negative keywords

-Pause or refine high-CPC, low-conversion terms

-Double down on high-intent keywords

Most accounts have a significant percentage of spend going to irrelevant or low-performing searches. Cleaning this up is one of the fastest ways to improve PPC performance.

Don’t Ignore Your Landing Pages

Sometimes, your PPC campaign isn’t the problem to begin with. It’s your landing page.

Audit your landing pages for:

-Messages that match your ads

-Load speed and mobile performance

-Clear conversion paths

-Friction in forms or checkout

Ads drive traffic. Landing pages convert it. If conversion rates are low, this is where you look.

Check the Signals Most People Ignore

This is where good audits become great ones.

Look at:

-Ad extensions and assets

-Search impression share

-Time-of-day performance

-Device-level performance

These details often explain why campaigns underperform even when everything else looks fine.

What a Good PPC Audit Actually Produces

A real PPC audit should give you:

-A clear list of wasted spend

-A prioritized action plan

-Quick wins you can implement immediately

-Long-term opportunities for scaling

If your audit ends with “optimize campaigns,” you didn’t go deep enough. PPC isn’t unpredictable. Most underperformance comes from things that are fixable. An audit forces you to face what’s actually happening in your account, not what you think might be happening.

If you run PPC campaigns and haven’t audited them in the last quarter, there’s a good chance you’re leaving performance on the table. Or worse, paying for results you’re not actually getting.
