PPC Audit Durban: What a Real Account Audit Delivers (and What a Pitch Deck Doesn't)

The Umhlanga Retailer Whose 'Free Audit' Recommended a Full Rebuild (Hypothetical Scenario)

Imagine a Durban-based homeware retailer with a Shopify store, spending around R60,000 a month on Google Ads. A self-described PPC agency offers a free audit. The deliverable: a 20-slide deck claiming the account is 'poorly structured' and needs a complete rebuild - new campaigns, new ad groups, new everything. The retailer signs a six-month retainer. Three months later, spend is up 30%, reported conversions look similar, but revenue is flat. What happened?

The 'audit' never inspected search terms, change history, or conversion settings. It was a sales pitch dressed as a diagnosis. A genuine PPC audit does the opposite: it gives you an independent, evidence-based assessment of what is working, what is wasting budget, and what to fix first - with a portable deliverable you can action in-house or hand to any competent manager.

What a PPC Audit Actually Is - and How It Differs From a Management Proposal

A PPC audit is a structured, vendor-neutral review of an existing advertising account - typically Google Ads, but often Meta or Amazon - against a defined checklist. Its purpose is to surface inefficiencies, misconfigurations, and opportunities, and to prioritise fixes by expected impact and effort. A management proposal, by contrast, is a sales document designed to win a retainer. The two can share data, but they serve different masters.

A real audit has three hallmarks:

• Account access required: read-only access to the ad platform, analytics, and ideally the e-commerce back end. Without it, the auditor is guessing.
• Scored baseline: each area (tracking, structure, bidding, creative, compliance) is rated against a rubric, so you can see the starting point and measure progress later.
• Portable deliverable: a written report with prioritised actions, expected impact, and owner - not locked inside an agency's proprietary dashboard.

Prebo Digital's reporting approach follows this principle: every audit produces a scored account-health snapshot and a fix list the client can keep, regardless of who implements it.

Tracking and Measurement: The First Audit Tranche That Everything Else Depends On

Before examining bids or ad copy, an audit must verify that the data feeding the algorithms is trustworthy. In our experience, conversion tracking is the most common source of phantom performance - and the easiest to fix.

What gets inspected:

• Conversion actions: Are all valuable actions (purchase, lead, add-to-cart) tagged correctly? Are some marked 'Primary' that should be 'Secondary' - or vice versa? Misclassification distorts Smart Bidding.
• Count settings: 'Every' vs 'One' conversion per click. For lead gen, counting every submission can inflate conversion volume and mislead bid strategies. For e-commerce, 'One' is usually correct.
• Attribution model and window: Google Ads may use data-driven attribution while GA4 uses last-click - leading to reconciliation gaps. The audit documents the mismatch and recommends a single source of truth.
• Consent Mode v2: For traffic from the EEA/UK, Consent Mode v2 has been mandatory since March 2024. For South African traffic, POPIA alignment is the relevant framework - not certification, but a documented consent approach reviewed by legal counsel.

For a Durban retailer selling nationally, delivery-cost attribution is another thorn: if shipping fees are baked into conversion value, reported ROAS may look healthy while margin erodes. The audit should flag whether conversion values reflect net revenue or gross.

Conversion Action Settings: Primary vs Secondary, and Why Count Settings Distort CPA

Google Ads allows you to designate conversion actions as 'Primary' (used for bidding and reported in the Conversions column) or 'Secondary' (observed but not used for bidding). A frequent error: leaving 'Add to cart' or 'Newsletter signup' as Primary, which trains Smart Bidding to chase low-value actions. The audit should map every action to its business value and recommend the correct hierarchy.

Count settings compound the problem. If a lead-gen form counts 'Every' submission, one user requesting three quotes inflates conversions by 3x, making CPA look better than it is. Switching to 'One' often reveals the true cost per lead - and may require bid strategy adjustments. See Google's official guidance on how conversions are counted.

Search-Term and Query Hygiene: Finding the Waste You Are Already Paying For

The search terms report shows the actual queries that triggered your ads. In many accounts, 20-40% of spend goes to irrelevant or low-intent terms - especially in broad match campaigns without negative keyword lists. For a Durban B2B wholesaler in Pinetown targeting 'industrial packaging', irrelevant terms might include 'packaging design course' or 'food packaging jobs'.

An audit must review at least the last 90 days of search terms, categorise waste, and propose negative keywords. It should also check for close variants and auto-applied recommendations - Google's 'Recommendations' page often suggests broad match or budget increases that may not align with your goals. The audit should assess whether auto-apply is enabled and whether it has caused unintended changes.

Account Structure and 12 Months of Change History

Campaign structure should reflect the customer journey and business lines. Common issues: too many campaigns splitting data, or a single campaign mixing brand and non-brand terms (leading to brand cannibalisation). The audit should assess whether structure supports clear budgeting and reporting.

Change history is the audit's forensic tool. Reviewing 12 months of changes reveals bid-strategy thrashing, panic edits after a bad week, and unexplained pauses. For example, a Durban guesthouse might have switched from tROAS to Maximise Clicks during a quiet season and never switched back. The audit documents these patterns. Google's change history guide explains how to access it.

Which Audit Format Suits Your Durban Business?

Not every business needs the same depth. We typically see three profiles:

Pricing is scope-dependent and indicative only. Always request a written scope document that specifies what will be inspected, what access is required, and what the deliverable includes.

Bidding, Budget Mechanics and the PMax-vs-Search Question

Smart Bidding is only as good as the signals it receives. An audit should verify that bid strategies align with business goals: tROAS for revenue, tCPA for lead volume. For a Durban e-commerce brand with variable margins, target ROAS must be set on profit, not revenue - otherwise the algorithm may push low-margin products. Budget mechanics matter too: shared budgets can mask overspend in one campaign, and day-parting may exclude valuable evening traffic (e.g., hospitality bookings after hours).

The PMax-vs-Search debate is central. Performance Max can cannibalise brand search and hide placement data. The audit should assess whether brand terms are properly excluded from PMax, whether asset groups are complete, and whether Search campaigns are still needed for high-intent queries. For a Pinetown manufacturer running B2B search, PMax may be less effective than a tightly themed Search campaign with negative keywords.

Creative, Asset Coverage and the Landing Page / Policy Sweep

Ad creative is often neglected in audits. Check responsive search ad strength, asset coverage (headlines, descriptions, images), and whether ad extensions (sitelinks, callouts, structured snippets) are used. For a Durban beachfront hotel, missing price extensions or promotion extensions could reduce click-through and conversion.

Landing pages are the final conversion barrier. The audit should review load speed (especially mobile), message match with ads, and policy compliance. Google's destination requirements cover unacceptable landing page practices - an audit must flag any risk of disapproval, such as unclear navigation or missing contact details.

Consent, POPIA Alignment and Audience Eligibility in South Africa

South Africa's Protection of Personal Information Act (POPIA) governs how you collect and use personal data. For PPC, this affects remarketing lists, customer match, and conversion tracking. An audit should verify that your consent banner captures the right permissions and that data flows into Google Ads only for consented users. Note: this is about alignment, not certification - always involve legal counsel.

For international traffic, Consent Mode v2 is required for EEA/UK users. Google's Consent Mode guide explains implementation. The audit should check whether consent signals are firing correctly and whether audience lists have shrunk unexpectedly. The South African Information Regulator provides POPIA guidance.

Audience Geography: Why a Durban Targeting Setting Can Bleed Into the Wider eThekwini Metro

Location targeting in Google Ads is not always precise. If you target 'Durban', you may reach users across the eThekwini Metropolitan Municipality - including Pinetown, Westville, Hillcrest, and even Ballito (which is in KwaDukuza, outside eThekwini). The audit should review location reports and recommend radius targeting or exclusion lists. For a service business with a physical location, over-targeting can waste budget on areas you cannot serve.

Statistics South Africa's Census 2022 data can inform population density and income levels per suburb, helping prioritise targeting.

Turning the Audit Into Outcomes: Baselines, 30/60/90-Day Follow-Through and Evidence

An audit without follow-through is a wasted expense. The deliverable should include a baseline measurement plan: which KPIs will be tracked, how they will be measured, and what success looks like at 30, 60, and 90 days. For example, if the fix is to switch conversion counting from 'Every' to 'One', the baseline is reported CPA, and the 30-day goal is to stabilise bidding with the new data.

A good audit report will also assign ownership: which fixes the client can do in-house, which require developer support, and which need an agency. This ensures accountability. Prebo Digital's conversion rate optimisation practice often follows an audit to implement landing page improvements.

Red Flags in a Durban PPC Audit Report

• No account access: If the auditor did not log in, the findings are generic.
• Full rebuild as first recommendation: Rebuilding resets learning and often wastes budget; it should be a last resort after exhausting optimisations.
• Missing search terms or change history: These are foundational; skipping them is negligence.
• Platform conversions treated as ground truth: A good audit reconciles with analytics and back-end data.
• No baseline or measurement plan: Without a before-and-after, you cannot prove the fixes worked.
• Non-portable deliverable: If you cannot take the report to another provider, it is a sales tool, not an audit.

Commissioning a PPC audit in Durban is an investment in clarity. Choose an auditor who inspects the right things, delivers a portable fix list, and helps you measure the outcome. Prebo Digital, as a Google Premier Partner (2022-2026) and Amazon Ads Partner, offers vendor-neutral audits that respect these principles.
