Digital Marketing Audit Checklist: What to Review and How to Fix What's Broken
A systematic checklist for auditing your digital marketing — from technical foundations to channel performance to competitive positioning. What to check and what to do about what you find.
Digital Marketing Audit Checklist: What to Review and How to Fix What's Broken
A marketing audit is a systematic review of what's working, what isn't, and what's changed since you last looked. Most businesses never do one — they add new activities without evaluating existing ones, accumulate tools and channels, and eventually discover they're spending time and money on things that stopped working months ago.
Technical foundation
Before evaluating strategy or creative, verify that the infrastructure actually works:
Analytics is tracking correctly. Are conversions being recorded? Are they attributed to the right channels? Test this: complete a conversion yourself and verify that it appears in your analytics with the correct source. If analytics is broken, every decision based on analytics data is suspect.
Your site loads fast and works on mobile. Test key pages on a phone over a cellular connection — not on your office WiFi. Check Google's PageSpeed Insights for specific improvement recommendations. A slow site hurts both user experience and search rankings.
AI crawlers can access your content. Check robots.txt for GPTBot, ChatGPT-User, ClaudeBot, PerplexityBot, Google-Extended. If they're blocked, your content is invisible to AI search. Many sites block them accidentally through security defaults.
Email authentication is configured. SPF, DKIM, and DMARC records should be in place. Without them, your emails are increasingly likely to go to spam regardless of content quality.
Channel performance
For each active marketing channel, answer:
What are we spending (money and time)? Include both direct costs (ad spend, tool subscriptions, agency fees) and indirect costs (internal time). Most audits undercount time, which makes channels look more efficient than they are.
What are we getting? Traffic, leads, conversions, revenue — attributed as accurately as your tracking allows. Use multiple attribution models, not just last-click. Compare to previous periods. Is performance improving, stable, or declining?
What's changed? Have costs increased? Has performance declined? Has the competitive environment shifted? A channel that was profitable six months ago might not be today, and you won't know if you're not comparing.
What should we stop doing? This is the most important and least asked audit question. Every channel and tactic that's underperforming consumes resources that could be reallocated to something that works better. The audit should produce a stop-doing list as well as a start-doing list.
Competitive positioning
Who are you actually competing with? Not who you think of as competitors — who Google ranks alongside you, who appears in the same consideration sets, who customers mention as alternatives. The competitive set is often different from what internal assumptions suggest.
What are competitors doing that you're not? Not just channels and tactics — messaging angles, content topics, offers, customer experience. Look for gaps more than threats. The most useful competitive insight is usually an underserved audience, an unaddressed objection, or a messaging angle nobody is using.
What are you doing that competitors aren't? Your distinctive capabilities, perspectives, or approaches. The audit should identify what makes you different and verify that this difference is visible in your marketing. Most companies' distinctive strengths are invisible to customers because the marketing doesn't communicate them.
Content and messaging audit
Review your highest-traffic pages. Are they current? Do they accurately represent your product and positioning? The pages that get the most visitors should get the most maintenance attention. Most businesses do the opposite — they maintain new content and let high-traffic pages go stale.
Review your messaging for consistency. If your homepage says one thing, your ads say another, and your sales team says a third, the customer experiences confusion rather than reinforcement. Consistent messaging across channels compounds. Inconsistent messaging cancels itself out.
Review for claims you can't support. In the rush to sound impressive, marketing language drifts toward overclaiming. The audit is a chance to correct language that promises more than the product delivers. Conservative claims that are true outperform bold claims that are aspirational.
