- Verify conversion tracking before anything else: if Google Tag Manager or Google Analytics 4 conversion tags are misfiring, every performance metric in the account is unreliable, and any optimisation decisions made on that data will be flawed.
- The search terms report is the fastest route to wasted spend: reviewing which actual queries triggered your ads reveals irrelevant traffic that can be cut by adding negative keywords and tightening match types across Google Ads and Microsoft Ads campaigns.
- Landing page relevance affects both Quality Score and cost per conversion: a page whose headline, offer and call to action do not match the ad copy will lower Ad Rank, raise cost per click and reduce the proportion of paid visitors who convert, regardless of how well the ad itself performs.
- A checklist format makes the audit repeatable: structuring the review across three defined pillars, tracking integrity, search term relevance and landing page alignment, means any member of the paid search team can run the same process consistently across multiple campaigns or accounts.
- Schedule audits at a fixed cadence, not only after a performance drop: regular reviews catch deteriorating match type coverage, accumulating irrelevant queries and broken UTM parameters before they compound into significant budget loss.
- When technical gaps surface during an audit, address the infrastructure: if the audit reveals that your ad platform, analytics stack and CRM cannot share conversion data reliably, API development for connecting ad platforms with your analytics stack resolves the root cause rather than masking it with manual workarounds.
01Tracking Audit
How do I check whether my conversion tracking is firing correctly in a PPC audit?
Start every PPC audit with the tracking layer. If conversion data is wrong, every optimisation decision built on top of it is wrong too. A tracking audit confirms that each conversion action is defined, implemented without errors, and feeding accurate data into both Google Ads and Google Analytics 4 (GA4) before you draw any conclusions about campaign performance.
Define your conversion actions first
A conversion action is any user behaviour you instruct Google Ads or Microsoft Ads to record as a goal, a form submission, a phone call, a purchase, or a booked demo. Before checking tags, list every active conversion action in your account and ask whether each one maps to a genuine business outcome.
- Separate primary conversions (actions that drive revenue decisions, such as a qualified lead form) from secondary or micro-conversions (actions such as a page scroll or a PDF download). Micro-conversions recorded as primary goals inflate your reported conversion volume and distort automated bidding strategies like Target CPA or Target ROAS.
- Remove or demote any conversion action that is no longer active, for example, a landing page that no longer exists.
Audit your tag implementation
Google Tag Manager (GTM) is a container that fires tracking tags based on triggers you configure. Common failure points include duplicate triggers firing the same conversion tag twice, tags attached to buttons that are no longer present in the page DOM, and tags blocked by cookie consent tools that were reconfigured after the original setup.
- Open GTM in preview mode and complete the conversion action yourself on a staging or live page.
- Confirm the tag fires exactly once per conversion event.
- Check the Google Ads conversion tag and the GA4 event tag separately, they serve different purposes and both need to fire cleanly.
If you use direct tag implementation (the global site tag placed in page source rather than GTM), check that the tag appears on every page in the conversion path and that no page caching or JavaScript errors are suppressing it.
Verify UTM parameters and GA4 data
UTM parameters are tracking strings appended to destination URLs (for example, utm_source=google&utm_medium=cpc) that tell GA4 where a session originated. Missing or inconsistent UTM parameters cause paid sessions to appear as organic or direct traffic in GA4, making cross-platform reporting unreliable.
| Check | Where to verify | Common failure |
|---|---|---|
| UTM parameters present on all final URLs | Google Ads URL column or URL checker tool | Parameters stripped by redirects |
| GA4 session source matches paid channel | GA4 Traffic Acquisition report | Auto-tagging conflict with manual UTMs |
| Conversion count in Google Ads vs GA4 | Side-by-side comparison in both platforms | Duplicate tags or attribution window mismatch |
A consistent discrepancy between Google Ads conversion totals and GA4 goal completions signals a tracking fault that must be resolved before you act on the data. For teams whose ad platforms need to exchange data with analytics or CRM systems, API development for connecting ad platforms with your analytics stack can replace fragile manual exports with reliable automated data flows.
02Search Terms
How do you audit a search terms report to cut wasted spend and fix match types?
The search terms report shows the actual queries that triggered your ads, not just the keywords you bid on. Reviewing it at both campaign and ad group level over a date range of at least 30 to 90 days reveals where budget is going to irrelevant traffic and where your match type settings are expanding reach in ways you did not intend.
Pull the report at the right level and date range
Export the search terms report from Google Ads or Microsoft Ads at the ad group level, not just the campaign level. Ad group-level data lets you see whether a specific theme is attracting off-topic queries. Choose a date range long enough to include statistically meaningful click and conversion data. A two-week window may miss seasonal patterns; a 12-month window may include performance from campaigns that have since changed significantly.
Identify queries consuming budget without converting
Sort the report by cost, then filter for queries with zero conversions. These are your primary candidates for negative keywords. Before adding a negative, check whether the query is genuinely irrelevant or whether it is relevant but paired with a weak ad or a poorly matched landing page. Misattributing a landing page problem as a keyword problem leads to over-pruning.
Review match type distribution
Broad match allows Google Ads or Microsoft Ads to show your ad for queries it considers related, including synonyms and related concepts. Phrase match requires the meaning of your keyword to be present in the query. Exact match restricts triggering to queries with the same meaning as your keyword. The table below summarises how each match type affects reach and control.
| Match type | Reach | Control | Best use case |
|---|---|---|---|
| Broad match | Highest | Lowest | Discovery campaigns with strong audience signals and sufficient conversion data |
| Phrase match | Medium | Medium | Campaigns where intent must be preserved but some query variation is acceptable |
| Exact match | Lowest | Highest | High-value terms where message match and bid precision matter most |
Build and layer negative keyword lists
Negatives can be applied at account, campaign or ad group level. Account-level negatives block a query across every campaign, which is appropriate for brand-safety terms or competitor names you never want to appear for. Campaign-level negatives handle themes irrelevant to a specific product line. Ad group-level negatives prevent cross-contamination between closely related ad groups. Maintain a shared negative keyword list and review it each time you run a search terms audit.
Flag high-impression, low-CTR terms
A query that generates many impressions but few clicks indicates a mismatch between what the searcher expects and what your ad promises. This is a signal to review ad copy for that keyword theme rather than immediately adding the term as a negative. Low click-through rate (CTR) on relevant queries also suppresses Quality Score, which affects Ad Rank and ultimately the cost per click you pay. See the practical guides on software, AI and digital growth for related measurement topics.
03Landing Pages
How do you audit landing pages for PPC relevance, message match and conversion performance?
A landing page audit checks whether the page a visitor reaches after clicking your ad earns that click. The four factors that matter most are destination URL alignment, message match, load speed and the clarity of a single primary call to action. Fixing these four areas directly affects Quality Score, bounce rate and cost per conversion.
Match the destination URL to the ad group theme
Each ad group should send traffic to a page built around the same keyword theme as its ads. Sending a user who searched for "enterprise inventory software" to a generic homepage breaks the connection between intent and content. During your audit, open the final URL for each ad group and confirm the page headline, body copy and offer reflect the specific search query the ad targets. A mismatch here raises bounce rate and lowers Ad Rankthe score Google Ads uses to determine ad position and cost per click.
Assess message match between ad copy and page headline
Message match means the headline a visitor reads on the landing page mirrors the promise made in the ad headline. If your ad reads "Book a Free Software Audit" but the page headline reads "Our Services", the visitor has to re-orient. That friction costs conversions. Check every active ad against its destination page headline and flag any pair where the language diverges significantly.
Review load speed on mobile and desktop
Page load speed is a direct input into Google Ads Quality Score. A slow page increases bounce rate and reduces the probability that a visitor reaches your call to action. Use Google's PageSpeed Insights to test each landing page URL on both mobile and desktop. Record the scores and flag pages that fall below the threshold Google classifies as "Good". Load speed problems often trace back to uncompressed images, render-blocking scripts or hosting infrastructure. If the underlying issue is architectural, browser-based web application development for landing page infrastructure may be the appropriate fix rather than a surface-level optimisation.
Evaluate the primary call to action
Each landing page should present one clear primary action: a form submission, a phone number, a demo request or a download. Multiple competing calls to action dilute focus. During your audit, record the following for each page:
- Whether a single primary CTA is visible above the fold on mobile
- Whether the CTA label matches the intent of the search query (for example, "Request a Demo" for a bottom-funnel keyword versus "Download the Guide" for an informational one)
- Whether the form length is proportionate to the commitment being asked of the visitor
- Whether trust signals, such as privacy statements or recognisable client logos, appear near the CTA
Check that page content addresses search intent
A visitor arriving from a specific search query carries a specific intent. Informational queries need explanatory content. Transactional queries need a direct path to purchase or enquiry. Read each landing page as if you had just typed the target keyword. If the page answers a different question, the content needs revision before you increase budget on that ad group. For teams whose landing page problems run deeper than copy, custom software built around your marketing and conversion workflows can provide the infrastructure to test and iterate pages independently of a monolithic website.
04Full Checklist
What does a complete PPC audit checklist look like across tracking, search terms and landing pages?
A complete paid search audit checklist organises every check under three pillars, tracking integrity, search term relevance and landing page alignment, assigns a priority to each item and notes whether the check requires platform access or a third-party tool. Working through the table below gives you a repeatable process you can run yourself or hand to a specialist.
How to use this checklist
Work top to bottom within each pillar. Mark each item PassFail or Not applicable in a shared spreadsheet. Record the specific finding in a notes column, for example, which campaign is missing UTM parameters or which landing page has a load time above three seconds. That record becomes your action backlog.
| Pillar | Checklist item | Priority | Access needed |
|---|---|---|---|
| Tracking | Confirm conversion actions are firing in Google Ads or Microsoft Ads tag diagnostics | High | Platform |
| Tracking | Verify Google Tag Manager container is published and tags are not paused | High | Google Tag Manager |
| Tracking | Check UTM parameters are present and consistent on all final URLs | High | Platform + GA4 |
| Tracking | Confirm Google Analytics 4 sessions match click volume within an acceptable variance | High | GA4 |
| Tracking | Identify duplicate conversion actions inflating reported conversions | High | Platform |
| Tracking | Check that offline conversion imports are uploading on schedule | Medium | Platform + CRM |
| Search Terms | Download the search terms report for the last 90 days and flag irrelevant queries | High | Platform |
| Search Terms | Add flagged irrelevant terms to negative keyword lists at campaign or account level | High | Platform |
| Search Terms | Identify high-spend, zero-conversion search terms and pause or exclude them | High | Platform |
| Search Terms | Review match type distribution, broad match, phrase match, exact match, against budget and Quality Score data | Medium | Platform |
| Search Terms | Check for cannibalisation between ad groups targeting overlapping queries | Medium | Platform |
| Landing Pages | Confirm headline and offer on each landing page match the ad copy driving traffic to it | High | Browser |
| Landing Pages | Test page load speed on mobile using a third-party tool | High | Third-party tool |
| Landing Pages | Verify the primary call-to-action form or button is above the fold on mobile | High | Browser |
| Landing Pages | Check that destination URLs return a 200 status, no 404 or redirect chains | High | Browser + crawler |
| Landing Pages | Review bounce rate and average engagement time per landing page in GA4 | Medium | GA4 |
Recommended audit cadence
Cadence depends on monthly spend and campaign complexity. Accounts with higher spend, multiple markets or frequent promotional changes need more frequent reviews. A practical starting point is a full audit every quarter, a search terms review every two weeks and a tracking check after any site deployment or tag change. If your landing pages are built on a browser-based web applicationcoordinate audits with your release schedule so tag changes do not break conversion tracking.
Documenting findings for handoff
Export your completed checklist as a CSV or shared Google Sheet. Group findings by pillar and priority. Add a column for the owner, platform, developer or content, so a specialist can pick up the backlog without a lengthy briefing call. Teams replacing manual reporting with integrated digital systems can connect this data directly to their reporting stack via API development for connecting ad platforms with your analytics stack.
05Next Steps
What should you do after a PPC audit: prioritise fixes, set a review schedule and decide when to bring in a specialist?
Once your audit is complete, the most common mistake is treating every finding as equally urgent. A structured triage process separates quick wins, changes you can apply in Google Ads or Microsoft Ads within hours, from structural changes that require campaign rebuilds, new landing page infrastructure or revised tracking architecture. Prioritising by impact and effort prevents audit fatigue and keeps budget working while deeper fixes are planned.
Triage findings into two tracks
Assign every finding to one of two tracks before touching the account.
- Quick wins include adding negative keywords from the search terms report, pausing zero-conversion ad groups, correcting broken UTM parameters and fixing conversion tracking tags in Google Tag Manager that fire on the wrong event.
- Structural changes include rebuilding campaign architecture around tighter ad groups, replacing generic landing pages with dedicated pages matched to each ad group's intent, and integrating Google Analytics 4 with your CRM so cost-per-conversion reflects pipeline value rather than raw form fills.
Set a recurring audit schedule
A single audit is a snapshot. Tie your review cadence to budget cycles and campaign launches rather than a fixed calendar date.
| Trigger | Recommended audit scope |
|---|---|
| Monthly budget review | Search terms report, negative keyword lists, conversion tracking verification |
| New campaign launch | Full tracking audit, landing page relevance check, match type review |
| Significant CTR or Quality Score drop | Ad copy, landing page alignment, audience segment review |
| Quarterly | Full three-pillar audit: tracking, search terms and landing pages |
Signs the account needs more than a self-serve audit
A self-conducted review works well for accounts with a clear structure and reliable tracking data. Bring in external help when you see any of the following: conversion data that cannot be reconciled between Google Ads and GA4, campaign structures inherited from multiple agencies with overlapping audiences, or landing pages built on legacy systems that cannot be modified without a development cycle. Cost and timeline for resolving infrastructure issues depend on the number of integrations, the state of existing tracking code and whether landing pages require new browser-based web application development for landing page infrastructure or can be updated within a CMS.
How a specialist audit differs from a self-conducted review
A specialist brings cross-account pattern recognition, access to platform benchmarks and the ability to diagnose tracking failures at the code level.
