A PPC audit is a structured review of your paid search and paid social accounts to find wasted spend, tracking errors, weak ad relevance, and missed conversion opportunities. For marketers, it matters because even small fixes to targeting, bidding, landing pages, and measurement can improve return on ad spend fast without increasing budget.
What to check in a PPC audit first
Start with the areas that affect spend and reporting immediately. Review campaign structure, conversion tracking, search terms, audience settings, and budget allocation before you touch creative.
Campaign structure and budgets
Check whether campaigns are grouped by product line, service, geography, or funnel stage in a way that supports clear reporting and bid control. If branded, non-branded, remarketing, and competitor campaigns are mixed together, performance data becomes harder to act on. Look for campaigns limited by budget, ad groups with too many keywords, and duplicate targeting that causes internal competition.
Tracking and attribution
Confirm that primary conversions reflect real business outcomes such as qualified leads, booked demos, purchases, or calls over a meaningful duration. Remove duplicate events, test form submissions, and verify that offline conversions or CRM outcomes are feeding back into the ad platform when possible. A clean audit often starts by fixing measurement, not bids.
How to find wasted spend and quick wins
Pull search term and placement reports to identify irrelevant traffic. Add negative keywords for low-intent queries, exclude poor placements, and review device, location, and schedule performance for segments that spend heavily but convert poorly. In paid social, check audience overlap and frequency to spot fatigue.
Ad relevance and landing page alignment
Compare your top-spend keywords or audiences with the ads and landing pages they trigger. If the ad promises pricing, speed, or a specific service but the landing page is generic, conversion rate usually suffers. Tighten message match, simplify forms, and make the primary call to action visible without scrolling.
Practical PPC audit example
A B2B software advertiser spends $8,000 per month on search. During the audit, the marketer finds broad match keywords pulling student and job-seeker queries, mobile traffic converting at half the desktop rate, and a demo form firing two conversion events per submission. After adding negatives, reducing mobile bids by 25%, separating branded traffic into its own campaign, and fixing duplicate tracking, reported cost per lead rises slightly but true qualified lead volume improves. That is a successful audit because it replaces misleading efficiency with usable performance data.
Build a repeatable audit workflow
Use a simple monthly process: export campaign performance, review tracking, scan search terms and placements, check audience and device splits, compare ad copy with landing pages, then prioritize fixes by impact and effort. For teams managing multiple accounts, keep a standard checklist in TLSubmit so audits are consistent across clients, channels, and reporting cycles.
