A Step-by-Step Guide to Audit Your PPC Account in 30 Minutes

This step-by-step guide will walk you through the most critical areas to examine during a rapid-fire account audit. We'll focus on the 80/20 principle – identifying the 20% of issues that are likely causing 80% of your problems.

1. Start with Account Structure and Settings (5 Minutes)

Begin your audit by examining the account's foundation. Navigate to your account settings and check your location targeting, language settings, and bid strategies. You'd be surprised how often accounts are accidentally targeting entire countries when they should focus on specific regions, or using automated bidding strategies that don't align with business goals.

Look for any shared budgets that might be causing uneven distribution of spend across campaigns. Check if ad scheduling is appropriate – there's no point showing B2B ads at 2 AM on Sundays if your target audience is tucked up in bed.

Quick audit tip: Export your campaign settings to a spreadsheet for a bird's-eye view. Look for inconsistencies in targeting, bidding, or scheduling that might be fragmenting your performance.

2. Analyse Campaign Performance and Budget Allocation (8 Minutes)

Head to your campaigns tab and set your date range to the last 30 days. Sort by cost to see where your budget is actually going versus where it should be going. Often, you'll discover that campaigns with poor conversion rates are consuming the lion's share of your budget whilst high-performing campaigns are limited by insufficient funding.

Create a simple mental matrix: high spend + low conversions = immediate attention required. Look for campaigns with conversion rates significantly below your account average – these are your quick wins waiting to happen.

Pay particular attention to search impression share data. If your best-performing campaigns are losing impression share due to budget constraints whilst poor performers have plenty of headroom, you've found your first major optimisation opportunity.

Action step: Identify your top 3 budget reallocation priorities. Note which campaigns need budget increases and which need immediate budget cuts or pausing.

3. Dive Into Keyword Performance and Search Terms (10 Minutes)

This is where the real detective work begins. Navigate to your keywords tab and sort by cost over the past 30 days. Look for keywords that are consuming significant budget but delivering poor results. These budget vampires are often broad match keywords that have drifted far from their original intent.

Next, examine your search terms report – this is absolutely crucial. You'll often find that your keywords are triggering searches you never intended to target. For instance, a client recently discovered their "marketing software" campaign was showing ads for "free marketing software download" searches, attracting bargain hunters rather than paying customers.

Look for patterns in irrelevant search terms. If you're consistently showing for searches containing "free," "cheap," or "jobs," you'll need to add these as negative keywords across relevant campaigns.

Immediate action: Create a list of negative keywords to add, and identify 3-5 high-spending, low-performing keywords to pause or reduce bids on immediately.

4. Review Ad Performance and Testing Strategy (4 Minutes)

Switch to your ads tab and look for ad groups with only one active ad – these represent missed opportunities for performance improvement. Google's machine learning algorithms work best when they can compare multiple ad variations and optimise delivery towards the best performers.

Check your ad rotation settings. If you're still using "rotate evenly," consider switching to "optimise" to let Google's algorithms favour your best-performing ads. However, ensure you have enough data volume to make this statistically meaningful.

Look at your ad extensions usage. Accounts without sitelinks, callouts, and structured snippets are leaving money on the table. Extensions improve ad visibility and click-through rates, often reducing your cost per click through improved Quality Scores.

Testing insight: Identify ad groups that need additional ad variations, and note any extensions that are missing across your campaigns.

5. Examine Quality Scores and Landing Page Experience (3 Minutes)

Add Quality Score columns to your keywords view (you'll find them under "Modify columns" > "Quality Score"). Focus on keywords with Quality Scores of 4 or below – these are costing you money through higher click costs and reduced ad visibility.

Low Quality Scores often indicate one of three issues: poor keyword relevance, weak ad copy, or landing page problems. Keywords with "Below average" landing page experience ratings should be your priority, as they're likely affecting multiple aspects of your account performance.

Quickly spot-check a few of your highest-spending keywords by clicking through your ads. Do the landing pages directly relate to the search query? Is the page loading quickly? Does the content match the ad promise? Misalignment here kills conversions.

Quality focus: List your worst-performing keywords from a Quality Score perspective and note any obvious landing page issues that need addressing.

Making Sense of Your Audit Findings

After your 30-minute audit, you should have a clear picture of your account's biggest opportunities. Typically, you'll find that budget reallocation alone can improve performance by 20-30% within the first week. Cleaning up search terms and adding negative keywords often reduces wasted spend by 15-25%.

The key is prioritisation. Focus on changes that will have the biggest immediate impact: pausing obviously poor performers, reallocating budgets to your best campaigns, and adding negative keywords to prevent irrelevant traffic. These quick wins buy you time to address longer-term issues like landing page optimisation and comprehensive ad testing.

Remember, a PPC audit isn't a one-off exercise. Schedule monthly 30-minute check-ins to catch issues before they become expensive problems. Your future self (and your budget) will thank you for the discipline.
