How often should a business run a marketing audit?

A full audit makes sense before a major change, such as hiring an agency, launching a new offer, or increasing budget, and at least once a year. Lighter quarterly reviews keep the roadmap current.

Can I audit my own marketing?

Yes, and this checklist is a starting point. An outside audit adds an objective view, which helps when internal teams are too close to the work.

Marketing audit checklist: what to review and in what order

Mrktgrowth Strategies · Updated October 9, 2026

Short answer

A marketing audit reviews how your business attracts, converts, and keeps customers, then ranks what to fix first. Start with tracking, because every other finding depends on trustworthy data, then review the website, paid media, email and lifecycle, search visibility, team, and tools, and finish with a prioritized 90-day roadmap.

1. Tracking and attribution

Confirm that the numbers are real before judging any channel.

GA4 and Google Tag Manager fire on every key action
Form fills, calls, and purchases are recorded as conversions
Leads in your CRM carry their original source
Offline outcomes such as signed clients or repeat orders are sent back to ad platforms where possible

2. Website and conversion

Review the pages that receive the most paid and organic traffic.

Mobile speed and usability
One clear primary action per page
Short forms that ask only what is needed
Trust signals near calls to action
Checkout or booking friction points

3. Paid media

Look at structure and spend, not just headline cost per click.

Spend by campaign against conversions that matter
Search terms and audiences that waste budget
Retargeting coverage
Landing page match between ad and page

4. Email, SMS, and lifecycle

Owned channels are often the fastest place to recover revenue already earned.

Welcome and nurture flows exist and trigger correctly
Re-engagement for lapsed customers or cold leads
List growth sources and consent
Revenue or pipeline attributed to email

5. SEO and AI search visibility

Search visibility now includes how ChatGPT, Perplexity, and Google AI Overviews summarize your business.

Technical health: indexing, sitemap, structured data
Pages that target real service and problem searches
Google Business Profile completeness where relevant
Whether AI assistants describe the business accurately

6. Team, process, and tools

Many performance problems are process problems.

Who owns each channel and decision
Agency and vendor deliverables versus cost
Tools that overlap or go unused
Handoffs between marketing and sales

7. The 90-day roadmap

Close the audit by ranking every finding by impact and effort. The first 30 days should fix measurement and the largest leaks; the next 60 should scale what works. Each item needs an owner and a next step.
