How to Audit Your Google Ads Account in 30 Minutes

Whether you have inherited a new client account, are taking over from another manager, or just want to sanity-check your own campaigns, a structured audit is the fastest way to find money-losing issues. The problem is that most audit frameworks take hours and produce 50-page reports no one reads. This 30-minute version focuses on the six checks that catch 90% of the money left on the table.

Grab a timer, open the Google Ads account, and work through each section in order. By the end, you will have a prioritized list of fixes ranked by financial impact. No fluff, no theoretical frameworks — just the checks that matter.

Minute 0-5: Conversion Tracking Health Check

Nothing else matters if conversion tracking is broken. Start here. Go to Tools & Settings > Conversions and check three things: (1) Are conversion actions recording data in the last 7 days? (2) Is the primary conversion action set correctly — the one Smart Bidding optimizes toward? (3) Are there duplicate or redundant conversion actions inflating your reported conversion volume?

• Check the 'Status' column — anything showing 'No recent conversions' or 'Tag inactive' needs immediate investigation
• Verify the primary conversion action matches your actual business goal (purchase, lead, call) — not a micro-conversion like page view
• Look for duplicate conversion actions that count the same event twice (common when both Google Ads tag and GA4 import are active)
• Confirm the attribution model is Data-Driven Attribution, not Last Click, for accurate Smart Bidding performance
• Test: complete a conversion yourself and verify it records within 24 hours

Minute 5-10: Budget Allocation Review

Open the Campaigns tab and add the 'Cost', 'Conversions', and 'Cost/conv.' columns. Sort by cost descending. The single most impactful finding in most audits is budget misallocation: campaigns spending the most money often are not the ones producing the most conversions at the best CPA.

• Flag any campaign spending more than 20% of total budget with CPA 2x above the account average
• Identify campaigns with strong CPA that are limited by budget — these are immediate scaling opportunities
• Check for campaigns with zero conversions in the last 30 days that are still spending — these need pausing or restructuring
• Verify budget distribution matches business priorities — sometimes legacy campaigns keep spending after the product or service they promote has changed
• Note any campaign hitting its daily budget before noon — this indicates the budget is too low for the keyword competition or the bidding is too aggressive

Minute 10-15: Search Terms and Wasted Spend

Go to Keywords > Search Terms and sort by cost descending for the last 30 days. This report shows you exactly what people searched for when they clicked your ads. In an unoptimized account, a noticeable part of spend can go to irrelevant search terms. Your job is to quantify how much waste exists.

• Highlight every search term with spend but zero conversions — sum the total cost to quantify wasted spend
• Flag search terms that are clearly irrelevant (competitor names you do not target, job searches, informational queries, wrong products)
• Check if negative keyword lists exist and are applied to all campaigns — missing negative lists is the most common cause of waste
• Look for search term patterns: if multiple irrelevant terms share a common word, one negative keyword can block them all
• Calculate wasted spend as a percentage of total spend — anything above 15% indicates a negative keyword problem

Minute 15-20: Quality Score Assessment

Add the Quality Score, Expected CTR, Ad Relevance, and Landing Page Experience columns to your keyword report. Filter for keywords with QS 1-5 and sort by cost descending. These low-scoring, high-spending keywords are where you are losing the most money to the Quality Score tax.

• Calculate the impression-weighted average Quality Score for the account — below 6.0 signals systematic problems
• Identify the underperforming component for each low-QS keyword: is it Expected CTR, Ad Relevance, or Landing Page?
• Check if low-QS keywords are concentrated in specific ad groups — this usually means the ad group structure needs splitting
• For keywords with QS 1-3 and no conversions, recommend pausing immediately — they are paying a massive CPC premium for no return
• Flag high-spending keywords where landing page experience is Below Average — these are quick wins since landing page fixes lift QS across multiple keywords

Minute 20-25: Ad Copy and Extensions Audit

Go to Ads & Assets and review the RSAs in each ad group. Check whether ad groups have at least one RSA with 'Good' or 'Excellent' ad strength, whether headlines include the target keywords, and whether all available ad extensions are active.

• Flag any ad group with only one RSA — Google recommends at least 2 RSAs per group for proper testing
• Check RSA ad strength: 'Poor' rated ads need more headline variety, keyword inclusion, or unique descriptions
• Verify sitelinks, callouts, and structured snippets are active at both account and campaign level
• Look for ad groups still running expanded text ads (ETAs) — these are legacy formats that should be replaced with RSAs
• Check if headlines include the primary keyword for each ad group — missing keyword inclusion is the top cause of Below Average ad relevance

Minute 25-30: Campaign Settings and Structure

Review campaign-level settings for common misconfigurations that silently waste budget. These are the settings most people set once and never revisit, but they can have an outsized impact on performance.

• Check network settings: if Search campaigns have 'Search Partners' or 'Display Network' enabled, review whether these placements convert — they often waste 10-20% of budget
• Verify location targeting is set to 'Presence: People in your targeted locations' not 'Presence or Interest' (the default), which shows ads to people outside your target area
• Review bid strategy: ensure campaigns with enough conversion data (30+ in 30 days) use Smart Bidding, not manual CPC
• Check for keyword overlap between campaigns — two campaigns bidding on the same term drives up your CPC through internal competition
• Verify ad rotation is set to 'Optimize' not 'Rotate indefinitely' — indefinite rotation prevents Google from favoring your best-performing ads

After the Audit: Prioritize and Act

You should now have a list of findings. Rank them by estimated financial impact: conversion tracking fixes first (they affect everything downstream), then budget reallocation, then wasted spend cleanup, then Quality Score improvements, and finally ad copy updates. Fix the top 3 issues within one week — do not create a 50-item to-do list that never gets done.

For ongoing monitoring, repeat this audit monthly. Each audit gets faster as you fix the structural problems. The goal is to reach a state where the monthly audit is a 15-minute confirmation that things are running well, rather than a 30-minute emergency triage.
