Digital Marketing Audit: What to Check, in What Order

A digital marketing audit is a structured review of your marketing spend and activity against one test: which parts turn into revenue, and where does money leak? It is not a traffic report. An audit ties activity and its cost to enquiries, sales and pipeline, then ranks the leaks so the biggest get fixed first.

Audits tend to fail for two reasons: channels get reviewed in isolation, or every flaw is listed with equal weight and nothing gets fixed. This guide sets out the order, a checklist per area and a 90-day plan, the approach our marketing strategy team uses when an engagement starts with an audit.

The right order for a digital marketing audit

A digital marketing audit should start with measurement and finish with brand. The order follows dependency, not importance: each area relies on trustworthy data from the one before it, so if tracking or attribution is broken, every later finding rests on numbers you cannot trust.

1. Measurement: GA4, conversions, consent mode and CRM attribution.
2. Conversion path and website: where visitors land and whether they can act.
3. Paid media: the fastest place to stop waste.
4. SEO and AI search visibility: unpaid discovery in Google and AI assistants.
5. CRM, email and retention: what happens after the first conversion.
6. Content and social: which output produces enquiries.
7. Brand and positioning: whether buyers understand why to choose you.

The marketing audit checklist, area by area

A marketing audit checklist works when every item is a specific test marked pass, fail or unknown. An unknown is a finding too: nobody owns that part of the system.

Measurement and tracking

Measurement comes first in a digital marketing audit because every other conclusion depends on it. Each conversion that matters should be recorded once, with its source, from first click to CRM record.

• GA4 key events. Key events, what GA4 used to call conversions, track the actions that make money: enquiries, bookings and purchases.
• Consent mode v2. Live and tested for EU visitors, with the ad_user_data and ad_personalization parameters Google's consent mode guide requires, so conversions from visitors who decline cookies can be modelled.
• Enhanced conversions. On in Google Ads, to improve conversion accuracy with hashed first-party data.
• Source capture. One written UTM convention, with hidden form fields passing UTMs and the Google click ID into your CRM.
• Deduplication. Meta's pixel and Conversions API share an event ID, and no Google Ads action is counted twice through a GA4 import and its own tag.
• Reconciliation. Conversions summed across ad platforms do not exceed real orders or CRM deals. If they do, something is double counting.

In our premium pet travel case study, we consolidated a sprawling account down to the campaigns with proven return, and Google Ads reached 3.65x blended return on ad spend month on month. Both depended on conversion values tracked against spend.

Website and conversion path

The website audit checks whether visitors who are ready to act can do so quickly on a phone. Most leaks here come from friction and missing tracking.

• Core Web Vitals. Google's Core Web Vitals guidance defines good as Largest Contentful Paint within 2.5 seconds, Interaction to Next Paint under 200 milliseconds and Cumulative Layout Shift under 0.1.
• Offer above the fold. On a phone, without scrolling, a visitor can see the offer and the next step.
• Form friction. Every required field earns its place, and the form works on your own phone.
• Tracking on every CTA. Forms, phone links, WhatsApp buttons, booking widgets and chat all fire an event.

If the problem is structural, such as a slow platform, the fix is a conversion-first website, not more traffic.

Paid media

A paid media audit looks for spend with no route to revenue: wasted queries, overlapping audiences, tired creative and budget that ignores margin.

• Search terms waste. Total 90 days of spend on irrelevant queries in the search terms report, then add negative keywords for the patterns.
• Match types. Broad match only where bidding learns from reliable conversion data.
• Brand vs non-brand. Reported separately, because people searching your name often convert anyway.
• Audience exclusions. Customers, recent converters, staff and job seekers are excluded from prospecting.
• Creative fatigue. On Meta, rising frequency with a falling click-through rate calls for new creative, not more budget.
• Budget vs margin. Spend follows margin, and every product line has a known break-even return on ad spend.
• Landing page relevance. Each ad group lands on the page that answers its query, not the homepage.

Our performance marketing team runs these checks before touching bids, because removing waste comes before adding spend.

SEO audit checklist

An SEO audit checks whether Google can find, index and rank the pages that make you money, and whether they still match search intent. Start in the free Google Search Console.

• Indexation. Every commercial page shows as indexed in the page indexing report, and you know why the rest are not. Google's Search Console guide covers that report and the URL Inspection tool.
• Titles and intent. Titles and headings match the query each page targets, and the page type matches what already ranks.
• Internal links. Every money page is linked from related content. No important page is an orphan.
• Content decay. Compare the last three months with the same period last year in the Search performance report, then refresh or merge pages losing clicks.
• Technical errors. Broken links, redirect chains, stray noindex tags, wrong canonicals and sitemap URLs that return errors.

AI search visibility checklist

An AI search audit checks whether ChatGPT, Gemini, Claude and Perplexity mention your business for your core queries, and which sources they cite. Google's documentation on AI features says AI Overviews and AI Mode have no additional requirements beyond SEO best practice, so fix SEO first.

• Prompt test. Ask each assistant 10 to 20 real buying questions, such as "best accountant for small businesses in Malta", and record whether and how you appear.
• Cited sources. Note which directories, review sites and articles the answers cite, and get listed on them accurately.
• Crawler access. Robots.txt and firewall rules do not block assistant crawlers such as OpenAI's OAI-SearchBot and PerplexityBot.
• Quotable facts. Your pages state services, locations, prices and results in plain, quotable sentences.

Our SEO and content service treats SEO and AI visibility as one workstream, because they share the same foundations.

CRM, email and retention

The CRM and email audit follows leads after the first conversion, where lost revenue never shows up in an ad dashboard.

• Lead response time. Submit test enquiries in office hours and in the evening, and time the first human reply.
• Lifecycle flows. Welcome, nurture, post-purchase and win-back sequences are switched on and have sent in the last 30 days.
• Pipeline hygiene. Every open deal has a source, owner and next step, and every lost deal a reason.
• List health. Judge engagement on clicks, not opens, because Apple's Mail Privacy Protection inflates open rates.
• Deliverability. SPF, DKIM and DMARC on every sending domain. Since February 2024, Gmail's bulk sender rules have required anyone sending over 5,000 messages a day to Gmail addresses to authenticate, offer one-click unsubscribe and stay under a spam threshold.

When the leak sits in pipeline design, the fix belongs with CRM consulting and revenue operations.

Content and social

The content and social audit separates activity that produces enquiries from activity that only produces output.

• Landing pages by key events. Sort GA4's landing page report by key events, not sessions, and compare the winners with what you spend most time producing.
• Self-reported attribution. A free-text "How did you hear about us?" field catches referrals, communities and AI assistants that tracking misses.
• Social by action. Judge each platform on profile visits, link clicks, messages and enquiries.

Brand and positioning

The brand audit asks whether a stranger can tell what you do, who it is for and why to choose you within seconds of landing on your site. Weak positioning makes every channel more expensive.

• Five-second test. Show your homepage to someone outside the business for five seconds, then ask what you sell and to whom.
• Proof on the site. Case studies with real numbers, reviews and credentials sit where buyers decide, and your Google reviews are recent and answered.
• One promise everywhere. Ads, website, social profiles and sales materials make the same core claim.

How to turn audit findings into a plan

Turn audit findings into a plan by scoring each issue on revenue impact, effort and confidence, then fixing measurement and the three biggest leaks first.

Score each issue from 1 to 5. Impact is the revenue it costs or could add. Effort is the time and money the fix needs. Confidence is how sure you are of the diagnosis. Rank by impact times confidence, divided by effort. Measurement fixes go to the top regardless, because they change every other score.

• Days 1 to 30: fix measurement, stop obvious paid waste and repair anything broken.
• Days 31 to 60: fix the three highest-scoring leaks, such as landing page relevance, lead response time or a nurture flow that never launched.
• Days 61 to 90: re-measure on clean data, re-score what is left and start slower work on content, AI visibility and positioning.

Our guide on how to build a marketing plan covers the next step: where budget goes once the leaks are closed.

DIY marketing audit vs outside help

A business can run a useful first-pass marketing audit itself in about a day with free tools. An outside audit earns its fee when the stakes are high or the team is too close to the work.

The one-day version uses Google Search Console for indexing and queries, GA4 for key events and landing pages, PageSpeed Insights for Core Web Vitals, and the diagnostics in Google Ads and Meta Events Manager. Submit a test form with GA4's Realtime report open to confirm the event fires.

Outside help usually pays for itself when:

• Ad spend is large enough that a small share of waste costs more than the audit.
• Growth is flat despite more activity and spend.
• A new marketing lead is joining and needs an honest baseline.
• You are choosing an agency and want every proposal to answer the same evidence.

Our guides to choosing a marketing agency and hiring a marketing consultant cover what to ask before you sign.

What good audit deliverables look like

A good marketing audit ends with a prioritised issue list and a 90-day roadmap, not a 90-page PDF. Every finding carries evidence, an owner and a next action.

• Prioritised issue list: each issue with its evidence, score and named owner.
• Quick wins: fixes that take under a day, such as negative keywords or a broken form.
• Measurement fix plan: what is broken, the order of repair and how each fix will be verified.
• 90-day roadmap: the top issues scheduled across 30, 60 and 90 days, each tied to a metric.

Test any audit you receive, including ours, with one question: could your team start work on Monday from page one?

Frequently Asked Questions

What is included in a digital marketing audit?

A digital marketing audit covers seven areas: measurement, the website and conversion path, paid media, SEO and AI search visibility, CRM and email, content and social, and brand positioning. The output is a prioritised issue list with evidence and owners, plus a 90-day plan that fixes the costliest leaks first.

How often should you audit your marketing?

Run a full marketing audit once a year and a lighter measurement and paid media check every quarter. Audit straight away after a major change, such as a website rebuild, a new CRM or a sudden drop in leads, because tracking often breaks quietly when systems change.

How long does a marketing audit take?

A first-pass marketing audit with free tools takes a business about a day. A full audit across measurement, website, paid media, SEO, CRM and brand usually takes two to four weeks, depending on how many channels, accounts and markets are involved. Collect platform logins before you start.

Can I do a marketing audit myself?

Yes. A business can run a useful marketing audit itself with free tools: Google Search Console, GA4, PageSpeed Insights and the diagnostics inside Google Ads and Meta. The limits are time and objectivity. Outside help pays off when ad spend is large, growth has stalled or nobody internally can judge the findings.

How much does a marketing audit cost?

The cost of a marketing audit depends on how many channels, accounts and markets it covers, how much ad spend is under review and whether fixing the issues is included. A single-channel review costs far less than a full audit. Judge the fee against the size of the budget being audited.

Find the leaks before you add budget

A digital marketing audit is one of the few marketing projects that can pay for itself, because it recovers money you already spend. Start with measurement and fix the three costliest leaks first.
