Marketing audit: a simple checklist to find where you lose customers

Most businesses don't have a marketing problem everywhere. They have one leaky step that quietly caps everything after it. A marketing audit is how you find that step. In this guide we walk you through a simple checklist, the numbers to look at, how to run the whole thing yourself in an afternoon, and what to do once you know where people are slipping away.

In short

A marketing audit is a structured look at every step people take from finding you to buying from you, using real numbers, so you can see where you lose the most people. You check traffic, leads, email and sales in turn, find the biggest drop, and fix that step first.

  • Every customer passes through four steps: they find you, leave their details, keep hearing from you, then buy.
  • The leakiest step caps everything after it, so find that one before you change anything else.
  • You can run a basic audit yourself in an afternoon with 90 days of numbers.

Who this is for: Coaches, consultants and founders whose sales have stalled and who want to know why before spending more.

01What is a marketing audit?

A marketing audit is a structured look at every step people take from first hearing about you to paying you. You put a number on each step, then look for the place where the most people drop away. That's it. No thick report and no fifty-page strategy deck. Just a clear picture of where people come in, where they leave, and roughly how many you lose along the way.

We think about it in four steps. They find you, through content, social or search. They leave their details, on a landing page or opt-in. They keep hearing from you, through email and automations. They buy, because the offer and the follow-up are clear.

Here's why the order matters. If only a handful of visitors ever leave their details, it doesn't matter how good your emails are. Hardly anyone is reading them. One leaky step caps everything after it. So the real job of an audit isn't to grade everything. It's to find the leakiest step first, because that's where a fix pays back the most.

02When should you do a marketing audit?

The honest answer is: earlier than most people do. Usually an audit happens after months of frustration. A few moments make it worth doing straight away.

  • Sales have gone flat. You're posting, emailing and taking calls, but the number of new clients isn't moving.
  • You're spending more and getting the same. More hours on content or more money on tools, with no change in results.
  • Before you hire or run ads. Ads and new hires pour more people into your system. If the system leaks, you just pay to lose people faster.
  • Once or twice a year anyway. Things drift. A form breaks, an email starts landing in spam, an offer goes stale. A regular check catches it.

If you recognise yourself in the first two, don't wait for a quiet week. The longer a leak runs, the more it costs you, and most leaks are cheap to fix once you can see them. Often it's one broken form or one email nobody opens, not your whole approach.

03What should a marketing audit checklist include?

Keep the checklist short and tie every item to a number. If you can't measure it, you can't tell whether it's the leak. Here is the checklist we use, one row per step.

StepWhat to checkThe number to look atWarning sign
They find youHow much traffic you get and where it comes fromVisitors per month, split by source (search, social, referrals)Almost all traffic from one source, or numbers falling for three months
They leave their detailsYour opt-in, landing page and the offer you give in returnVisitor-to-lead rate (new leads divided by visitors)Plenty of visitors but very few sign-ups
They keep hearing from youYour welcome emails, regular emails and whether they reach the inboxOpen rate, reply rate and inbox placementOpens dropping, no replies, or emails landing in spam or Promotions
They buyYour offer, booking process and follow-up after callsLead-to-call rate and call-to-client rateLots of leads who never book, or calls that rarely turn into clients

Don't worry about matching some industry figure. Compare each step with your own past numbers and with the steps either side of it. A sharp drop is usually obvious once it's written down. For the email row, our free email deliverability tester shows whether you're actually reaching the inbox.

04How do you do a marketing audit yourself?

You can run a useful audit in an afternoon. You need your analytics, your email platform, your calendar and a notepad. Work through it in this order.

  1. Gather the last 90 days of numbers. Visitors, new leads, email opens and replies, calls booked and clients won. Ninety days smooths out a lucky or unlucky week.
  2. Map the path. Write down every step a stranger takes to become a client, in order. Click through it yourself as if you'd never heard of you.
  3. Find the biggest drop. Put the numbers next to each step and see where the count falls hardest.
  4. Check the obvious causes. Broken links, a slow page, a vague headline, a form asking too much, emails in spam, no follow-up after calls.
  5. Pick one fix. Choose the change most likely to help at that step and write it down.

Then comes the part people skip. Fix the biggest leak first, even if another step feels more exciting. And change one thing at a time, so you know what worked. Give it a few weeks, check the same numbers again, then move to the next leak. If the drop is on your landing page, our guide on why your funnel isn't converting goes deeper, and how to increase your conversion rate covers the buying step.

05Should you do a marketing audit yourself or get one done?

Doing it yourself is a great start. You know your business, you have the logins, and the numbers alone often point straight at the problem. If you've never mapped your path before, our guide on how to set up a sales funnel helps you see the steps clearly.

The trouble is that you're close to it. You know what your headline means, so it reads as clear to you. You know the booking link is in the third email, so it feels easy to find. An outside audit brings fresh eyes that see what a stranger sees. It also brings a sense of what's normal, because someone who has looked at lots of businesses can tell a small dip from a real leak.

That's why we offer a free marketing audit. We go through all four steps, find where you're losing the most people, and tell you in plain English what we'd fix first. No obligation. If you'd rather start on your own, use the checklist above, and come back to us when you want a second pair of eyes.

06Common questions

How long does a marketing audit take?

A simple audit you run yourself takes an afternoon if your numbers are easy to find. A more detailed one, where someone clicks through every page and email, can take a few days. Most of the time goes on gathering numbers. Once they're in front of you, the biggest drop usually jumps out within minutes.

What is the difference between a marketing audit and an SEO audit?

An SEO audit only looks at how well your site shows up in search. A marketing audit looks at the whole path, from how people find you to whether they buy. Search is one part of the first step, so an SEO audit fits inside a marketing audit. Plenty of businesses rank well and still lose people at the opt-in or the sales call.

How often should I do a marketing audit?

Once or twice a year is enough for most small businesses. Do one sooner if sales go flat, results drop after a change, or you're about to spend money on ads or a new hire. Keep a note of your numbers each time, so the next audit can compare like with like.

Is there a free marketing audit I can get?

Yes. Unbury offers a free audit that checks every step from finding you to buying and points out the biggest leak. We tell you in plain English what we'd fix first. You can also run the checklist in this guide yourself at no cost.
