A well-run ecommerce ad account audit checklist covers eight core areas: conversion tracking, account structure, campaign budgets, keyword quality, audience segmentation, ad creatives, bidding strategies, and attribution. Get all eight right and your Google Ads and Facebook Ads accounts work together to drive profitable growth. Miss even one and you risk haemorrhaging budget on traffic that will never convert.
Before you touch a single campaign setting, here is what your audit must confirm:
- Conversion tracking is accurate — every purchase fires once, revenue values are dynamic, and attribution settings reflect your actual customer journey.
- Campaign structure is clean — branded, non-branded, Shopping, remarketing, and prospecting campaigns are separated, not bundled together.
- Facebook Pixel and Conversions API are both active — relying on the Pixel alone leaves gaps in your attribution data.
- Campaign Budget Optimisation (CBO) is configured correctly — budgets sit at the campaign level so Meta’s algorithm can shift spend toward winning ad sets.
- Learning phase thresholds are being met — ad sets need 50 conversions per week to exit the learning phase and deliver stable results.
- Negative keyword lists are maintained — irrelevant search terms drain budget silently.
- Creative variety is sufficient — on Meta, creative quality is now the primary targeting signal, not audience parameters.
- Attribution models are understood — in-platform ROAS figures rarely tell the full story; blended metrics like media efficiency ratio (MER) give a more accurate read on profitability.
This checklist applies whether you are spending £5,000 or £500,000 per month. The principles scale. What follows is the platform-specific detail you need to act on each point with confidence.
Google Ads audit checklist for ecommerce accounts
A Google Ads ecommerce ad account audit starts with the data layer, not the campaigns. If your conversion tracking is broken, every decision you make downstream is built on sand.
Conversion tracking and revenue data
- Confirm that purchase conversions fire once per transaction, with no duplication or gaps.
- Validate that dynamic order values are passing correctly into Google Ads and match your Google Analytics 4 data.
- Check your attribution model: data-driven attribution is the 2026 default and generally the most accurate for ecommerce, but confirm it suits your purchase cycle.
- Exclude micro-conversions such as add-to-cart from your primary bidding signal. Bidding to add-to-cart inflates conversion volume while obscuring actual purchase profitability.
- Cross-reference Google Ads conversion data against your ecommerce platform’s order reports to catch discrepancies early.
Campaign and ad group structure
Poor structure is the most common cause of wasted spend in Google Ads. Segment campaigns by brand versus non-brand, product category, margin tier, and customer intent. Mixing these together makes it impossible to control bids or budgets with any precision.
- Separate branded search from non-branded search. They have different intent, different conversion rates, and different ROAS expectations.
- Group products by margin or profitability, not just category. A high-volume, low-margin product should not compete for budget with a high-margin hero SKU.
- Keep prospecting and remarketing audiences in separate campaigns.
- Use consistent naming conventions across campaigns, ad groups, and assets so performance is easy to read at a glance.
- Avoid excessive ad group fragmentation. Too many small ad groups starve the algorithm of conversion data and prevent the learning phase from completing.
Keywords, search terms, and negative keywords
Negative keywords and search term refinement are among the highest-ROI activities in any Google Ads audit. Pull the search terms report and look for queries spending budget without generating sales.
- Add irrelevant, informational, or employment-related queries as negative keywords immediately.
- Review match types. Broad match can scale traffic effectively, but only when paired with strong negative keyword lists and sufficient conversion data for Smart Bidding to work from.
- Prioritise buying-intent terms containing words like “buy,” “order,” “discount,” or specific product model numbers.
- Protect your branded terms. Monitor whether competitors are bidding on your brand name and confirm your own branded campaigns are running efficiently.
- Check for keyword cannibalisation across ad groups where multiple groups are competing for the same queries.
Bidding strategies and ROAS targets
Your bidding strategy should reflect your business goals, not just platform defaults. A target ROAS set too high restricts volume; set too low, it grows revenue at the expense of margin.
- Factor in product margins, return rates, shipping costs, and promotional discounts when setting ROAS targets.
- For campaigns with limited conversion volume, consider Target CPA or Maximise Conversions before moving to Target ROAS. Smart Bidding needs data to work well.
- Review bid adjustments for device, location, and audience segments. These can still add value alongside automated bidding when the data supports them.
- Check Performance Max campaigns separately. Confirm asset groups are well-organised, audience signals are populated, and you are reviewing the search terms insight report regularly.
Ad copy, extensions, and landing pages
- Audit ad copy for relevance to the keywords triggering each ad group. Generic copy wastes Quality Score and click-through rate.
- Check that all available ad assets (formerly extensions) are active: sitelinks, callouts, structured snippets, price assets, and promotion assets where relevant.
- Landing page relevance directly affects conversion rate. A product ad should land on the specific product page, not a category page.
- Test page load speed on mobile. Slow pages kill conversion rates regardless of how well the ad performs.
- Confirm trust signals are visible: customer reviews, return policy, delivery information, and clear pricing.
Dynamic product ads and SKU-level campaigns
Dynamic product ads personalise ad content to the viewer’s browsing behaviour, making them one of the most effective formats for ecommerce retargeting. Audit your product feed for completeness: titles should include brand, product type, size, colour, and model number where applicable. Weak feed attributes reduce match quality and limit impression share on Shopping campaigns.
Pro Tip: Separate your top-selling SKUs into their own Shopping campaign with a higher priority setting. This gives you direct budget control over your most profitable products rather than letting them compete with slower-moving stock.
Facebook Ads audit checklist for ecommerce performance
The Facebook Ads audit starts with your tracking infrastructure. Without accurate data flowing into Meta’s algorithm, even a well-structured account will underperform.
Pixel and Conversions API verification
Accurate pixel firing and event tracking are the foundation of everything Meta’s algorithm does. A Pixel alone is no longer sufficient; the Conversions API (CAPI) is now standard practice for ecommerce accounts.
- Confirm the Facebook Pixel fires on all key pages: product views, add-to-cart, initiate checkout, and purchase.
- Verify that the Conversions API is active and deduplication is set up correctly. Duplicate events distort your data and cause the algorithm to optimise against inflated signals.
- Check that purchase events are passing dynamic revenue values, not fixed amounts.
- Review your attribution window settings. A 7-day click, 1-day view window is a common starting point for ecommerce, but your purchase cycle may warrant adjustment.
- Use Meta’s Events Manager to confirm event health scores and identify any events flagged as low quality.
Account structure and Campaign Budget Optimisation
CBO combined with an appropriate bid strategy improves ad spend efficiency by letting Meta’s algorithm allocate budget dynamically across ad sets. Auditing your account structure means checking whether this automation has the right conditions to work.
- Confirm CBO is active at the campaign level for scaling campaigns. Ad set-level budgets (ABO) are better suited to testing phases where you need clean, isolated reads on performance.
- Check that each CBO campaign contains a manageable number of ad sets. Too many ad sets split the budget too thinly and prevent any single ad set from exiting the learning phase.
- Review cost caps and bid caps. A cost cap set too aggressively can throttle delivery before the algorithm has enough data to optimise.
- Separate prospecting, retargeting, and loyalty campaigns into distinct campaign structures. Mixing objectives within a single campaign confuses the algorithm’s delivery optimisation.
Audience segmentation: retargeting, lookalikes, and prospecting
- Audit your retargeting audiences for recency and size. A 180-day website visitor audience behaves very differently from a 7-day add-to-cart audience; they should not share the same ad set.
- Check lookalike audience source quality. Lookalikes built from a small or unqualified Custom Audience produce weak results. Build from purchasers, not just website visitors, where possible.
- Review audience overlap between ad sets. Overlapping audiences cause internal competition and inflate your CPMs.
- For prospecting, consider whether broad targeting with strong creative is outperforming narrow interest-based targeting. On Meta in 2026, it often does.
- Confirm Advantage+ audience settings are configured intentionally, not left on default without review.
Ad creatives and copy
Creative quality is now the primary targeting signal for Meta’s algorithm. The era of hyper-precise audience targeting doing the heavy lifting is over; the creative itself tells the algorithm who to find.
- Audit creative variety within each ad set. Running a single static image with no alternatives starves the algorithm of signals and accelerates creative fatigue.
- Check that video, carousel, and static formats are all represented. Different formats resonate with different audiences and placements.
- Review ad copy for compliance with Meta’s advertising policies. Non-compliant copy can trigger disapprovals that reset learning.
- Assess whether your creative reflects your current product range and promotions. Outdated creative undermines relevance scores.
- Look at your Meta Ads creative strategy for ecommerce: the best-performing accounts treat creative testing as a continuous process, not a one-off task.
Learning phase and ad set scaling
Significant edits to an ad set, such as changing the bid strategy, audience, or budget by a large amount, reset the learning phase. This is one of the most common and costly mistakes in Facebook Ads management.
- Identify ad sets currently in learning or learning limited status. Learning limited usually signals insufficient conversion volume or excessive fragmentation.
- Avoid making multiple changes to the same ad set simultaneously. If changes are necessary, batch them so the ad set only goes through one learning period.
- Do not pause and reactivate ad sets frequently. Each pause risks resetting accumulated learnings.
- Scale budgets gradually, typically no more than 20% at a time, to avoid triggering a full learning reset.
How to build and maintain your audit process over time
A one-off audit is useful. A regular audit cadence is what actually compounds into profitable growth. The difference between accounts that scale and those that plateau is usually discipline in the review process, not a single clever optimisation.
Pro Tip: Set a fixed audit schedule tied to your spend level. Higher-spend accounts warrant weekly reviews of key metrics and a monthly deep-dive. Lower-spend accounts can run on a fortnightly check with a quarterly structural review.
Here is how to build a process that holds up:
- Consolidate before you optimise. If your account has too many campaigns or ad sets each receiving low conversion volume, consolidation comes first. Fragmented accounts cannot exit the learning phase reliably, and no amount of bid tweaking fixes a structural data problem.
- Use blended metrics, not just platform ROAS. Native platform ROAS figures are useful but incomplete. Media efficiency ratio (MER), calculated as total revenue divided by total ad spend, gives you a truer picture of account-wide profitability.
- Document every change you make. A change log lets you attribute performance shifts to specific actions rather than guessing. This is especially important when multiple people manage the same account.
- Prioritise creative refresh over structural tinkering. Once your account structure is sound and learning phases are stable, creative quality is the lever with the most upside. New creative does not reset learning the way audience or bid changes do.
- Cut and scale on data, not instinct. Give campaigns at least two to three weeks of data before drawing conclusions, longer for lower-spend accounts. Premature cuts waste the learning investment already made.
- Automate monitoring, not decisions. Use automated rules and performance dashboards to flag anomalies: sudden CPM spikes, conversion rate drops, or budget pacing issues. Let the alerts surface the problems; make the decisions yourself.
- Assign priorities to audit findings. Not every issue carries the same weight. Broken conversion tracking is a P1 fix. A slightly suboptimal ad headline is a P3. Work through findings in order of revenue impact, not ease of fixing.
A structured digital marketing audit checklist that you revisit consistently will outperform any single clever campaign tweak. The accounts that grow reliably are the ones where the fundamentals are checked, documented, and improved on a schedule.
