PPC Audit Checklist: Find Wasted Spend Before You Scale

A PPC audit is a systematic review of an ad account that surfaces wasted spend and quick wins in five areas: conversion tracking, account structure, search terms, bids and budgets, and ads and landing pages. Work them in that order. Tracking comes first because every other number is unreliable if conversions are counted wrong, and most accounts hide 15 to 30 percent wasted spend that a two-hour audit will find.

This checklist walks each area with the specific checks to run and the red flags that signal money leaking out. Use it to audit your own account or to pressure-test an agency's work. If you would rather have a second set of eyes run it, our PPC audit services team pressure-tests the account for you.

Start with conversion tracking, because everything depends on it

If tracking is broken, every optimization built on it is guesswork. Audit tracking first and fix it before touching anything else.

• Confirm conversions fire once per action, not on every page load. Duplicate tags inflate conversion counts and hide the true cost per lead.
• Check that the conversions counted are the ones that matter, booked calls and qualified leads, not newsletter signups padding the number.
• Verify the conversion window and attribution model match the sales cycle. A 90-day B2B cycle counted on a 7-day window undercounts badly.
• Test the primary conversion path end to end, from click to thank-you page, on desktop and mobile.
• Confirm offline conversions import if the sale closes by phone or in person.

Accounts with clean tracking optimize toward revenue. Accounts with broken tracking optimize toward noise, and no bid change fixes that.

Pay attention to conversion values, not just conversion counts. An account that counts every lead as equal tells smart bidding that a 50 dollar order and a 5,000 dollar order are worth the same, so the algorithm chases volume over value. Assign a value to each conversion action, even a rough one, so the bidding learns to prefer the leads that actually pay. This single fix often shifts spend toward the campaigns that carry the business.

Review account structure for control and relevance

A messy structure makes every other lever harder to pull. The audit checks whether campaigns and ad groups are organized so budget and messaging can be controlled.

• One theme per ad group. Ad groups with 30 unrelated keywords cannot show relevant ads and drag quality scores down.
• Campaigns separated by goal, geography, or budget priority so spend can be steered, not averaged.
• Search and Display in separate campaigns. Bundled together, Display eats the budget at a fraction of the intent.
• Branded and non-branded terms split apart so branded conversions do not flatter non-branded performance.
• Quality Score checked across top keywords. Scores of 3 or 4 signal a mismatch between keyword, ad, and page.

Poor structure is rarely the single biggest leak, but it is the one that makes every other fix stick. Clean it before optimizing bids.

The step-by-step audit checklist

Work this table top to bottom. Each row is a check, what to look for, and the action when the check fails.

Audit area	What to check	Red flag	Action
Conversion tracking	Tags fire once, correct actions counted	Duplicate conversions, soft actions counted	Fix tags, redefine primary conversions
Account structure	One theme per ad group, goals separated	30 keywords per group, Search and Display bundled	Rebuild ad groups, split campaigns
Search terms	Actual queries triggering ads	Irrelevant queries, spend with zero conversions	Add negatives, pause dead keywords
Match types	Broad match under control	Broad match with no negative list	Add negatives or tighten match types
Bids and budgets	Spend flows to converting campaigns	Budget on high-cost, zero-conversion terms	Reallocate, set target CPA or ROAS
Ad copy	Ads match keyword and offer	One ad per group, generic copy	Add variants, match ad to search
Landing pages	Page matches ad, loads fast, converts	Ads point to homepage, slow mobile load	Build matched pages, fix load time
Geographic targeting	Serving only where you sell	Spend in regions you do not serve	Tighten location targeting
Ad schedule	Ads run when leads are handled	Spend at hours nobody answers	Schedule to staffed hours
Device performance	Mobile vs desktop conversion rates	Mobile spend high, conversions low	Adjust device bids or fix mobile page

Run every row. The leaks that add up to 15 to 30 percent wasted spend rarely come from one place, they come from three or four small ones the checklist catches together.

Dig into search terms, the fastest place to find waste

The search terms report shows the actual queries that triggered your ads, and it is where most wasted spend hides. This is the highest-return check in the audit.

• Sort by cost and scan for queries with spend and zero conversions. Every one is a candidate negative keyword.
• Look for irrelevant intent: free, jobs, DIY, competitor names, or unrelated products. Add them to a negative list.
• Find high-converting queries buried in broad ad groups and promote them to their own exact-match keywords.
• Check that broad match keywords have a negative list protecting them. Broad match with no negatives is the single most common cause of runaway spend.

An account that has never had its search terms pruned typically wastes 20 percent or more of its budget on queries that will never convert. This one report often pays for the entire audit. For what to do after the audit, see how to optimize PPC campaigns.

Audit the automation and bidding settings

Modern accounts hand more decisions to Google's automation, and the audit has to check whether that automation is working for you or against you. A smart bidding strategy fed bad data or pointed at the wrong target wastes budget while looking busy.

• Confirm each campaign's bid strategy matches its goal. A lead-gen campaign on Maximize Clicks buys traffic, not leads, and should run Maximize Conversions or Target CPA instead.
• Check that any target CPA or ROAS is realistic. A target set far below what the account has ever achieved starves the campaign of impressions, and one set too loose overspends.
• Review whether smart bidding has enough conversion volume to work. Below 15 to 30 conversions a month, automated bidding guesses, and manual control often does better.
• Look at Performance Max and broad match together. When both run without tight audience signals and negatives, they can overlap and cannibalize the same searches at a higher cost.
• Check auto-applied recommendations. Google can apply changes automatically, and some of them widen targeting in ways that raise spend without raising results.

Automation is a tool, not a set-and-forget switch. The audit confirms someone chose the strategy on purpose and that the data feeding it is clean, because a bidding algorithm only optimizes toward the goal and the conversions you give it.

Check bids, budgets, ads, and pages last

With tracking clean, structure sound, and search terms pruned, the audit finishes on the levers that turn findings into results.

• Bids and budgets: confirm spend concentrates on campaigns that convert. Move budget off high-cost, zero-conversion terms. Set a target CPA or ROAS once there are 15 to 30 conversions a month feeding the algorithm.
• Ad copy: every ad group needs at least two or three variants so the account can test, and the copy should echo the keyword and a specific offer, not a generic tagline.
• Landing pages: confirm ads point to a matched page, not the homepage, that the page loads in under three seconds on mobile, and that the conversion action is visible without scrolling.

These are the last checks because they only pay off once tracking is trustworthy and the account is structured to steer. Fix them in that order and the audit converts into lower cost per lead within a month or two.

Turn the audit into a prioritized action list

An audit only pays off if the findings get worked. Close it by ranking every issue so the biggest recovery lands first.

• Sort findings by dollars leaking, not by how quick the fix is, so a broken conversion tag outranks a missing ad variant
• Fix tracking before anything else, because every later change is judged against numbers you can finally trust
• Group the waste fixes next: negatives, geographic trims, and Search-Display splits recover budget within days
• Leave structure rebuilds for last, since they pay over weeks and can be staged without pausing the account
• Put an owner and an expected recovery beside each item so the work ships instead of sitting in a report

A one-page plan turns a static findings list into a schedule someone can act on.

Watch for the leaks that hide between audits

Some waste does not show until you look at the reports side by side. A few cross-checks catch what a single view misses.

• Compare cost per lead by device, since a high mobile spend with low mobile conversion often points to a slow or broken mobile page
• Check the ad schedule against when leads actually get answered, so you stop paying for clicks at hours nobody follows up
• Read the placement report on any Display or Performance Max spend for junk apps and sites draining budget
• Reconcile Google Ads conversions against the CRM monthly, since a gap between the two is usually a tracking or attribution problem

Catching these between quarterly audits keeps small leaks from compounding into a big one.

Frequently asked questions

How long does a PPC audit take?

A focused audit of a single account takes two to four hours for the checks in this list. A large account with dozens of campaigns and multiple platforms can take a full day. The search terms review and tracking verification alone take about an hour and surface most of the wasted spend.

What is the most common problem a PPC audit finds?

Wasted spend in the search terms report, usually from broad match keywords with no negative list pulling irrelevant queries. Accounts that have never been pruned commonly waste 20 percent or more of their budget on searches that will never convert. Broken or duplicate conversion tracking is the second most common finding.

How often should I audit a PPC account?

Run a full audit quarterly, and a lighter search terms and budget review every two weeks. Ad platforms change, competitors shift, and broad match keywords drift into new queries over time, so an account left unaudited for six months almost always develops fresh waste.

Can I do a PPC audit myself or do I need an agency?

You can run this checklist yourself if you have access to the account and the search terms and conversion reports. The judgment calls, which conversions to count, how aggressively to reallocate, come with experience. Many owners run the checklist to spot red flags, then bring in help to act on them.

What tools do I need to run a PPC audit?

The ad platform's own reports cover most of it: the search terms report, the conversion tracking status, and the auction insights. Add Google Analytics or your conversion platform to confirm tracking fires correctly, and a spreadsheet to hold the findings and their priority scores. You do not need paid audit software to run this checklist thoroughly.

Does a PPC audit fix the account or just find problems?

An audit finds and ranks the problems. The fixes are separate work that follows the ranked plan the audit produces. Treat the audit as the diagnosis and the optimization that follows as the treatment, and expect the cost per lead to improve over the month or two it takes to work the backlog, not the day the audit finishes.

What is a digital marketing audit?

A digital marketing audit reviews the channels, pages, tracking, and reporting that influence leads or sales. A PPC audit is one part of that wider review, focused on paid search structure, spend, targeting, ads, landing pages, and conversion tracking.

Where to go next

A PPC audit that works follows an order: fix tracking, sort structure, prune search terms, then tune bids, ads, and pages. Run the checklist in that sequence and you will surface the 15 to 30 percent wasted spend most accounts hide. If you want a team to audit your account, PPC audit services.
