Look at first

  1. Audience and market
  2. Positioning and brand
  3. Website

Without a clear audience, no channel can be judged fairly. That’s why the audience comes first whenever it isn’t truly solid.

The process

  1. Set the goals

    It starts with one clear main goal. That could mean getting more leads, for example, or paying less for each one. Every channel is later measured against those goals.

  2. Data and audience

    Every channel puts its numbers on the table. On top of that you need a clear picture of who buys and which competitors you’re up against.

  3. Assess and plan

    Each channel is kept, improved or stopped. At the end there’s a plan that says what comes first and where the money goes.

The website at the center

  • Every channel ends there

    Whether someone sees an ad, reads a newsletter or gets an AI answer, many of them end up on your website. So if the website falls short, the other channels lose impact too.

  • AI search as a new channel

    If you ask ChatGPT or Perplexity for a provider, you get companies named, and Google’s AI Overviews do the same. The audit checks whether your company is among them. There’s more in our GEO guide.

  • Check the website first

    Your website is completely in your own hands, and you can review it without spending anything on ads. Our guide on how to do a website audit walks you through it step by step.

  • Ads after the website

    With pay-per-click ads, every visit costs money, lead or not. That’s why we suggest fixing the website first.

Marketing audit: common questions

What is a marketing audit?

A marketing audit goes through everything a company does to win customers, one area at a time.2 It starts with the audience and how the company presents itself. From there it moves on to the website and search, and all the way to email, social media and ads. At the end there’s a plan for what should get better.1

What does a marketing audit include?

It covers seven areas, starting with your audience and market and your positioning. Then it moves on to the website, search and AI search, and your content. Email, social media and ads come last. Each area gets one guiding question and the data that answers it.

What is a digital marketing audit?

It is a marketing audit that only looks at the online channels, so the website, search, content, email, social media and online ads. For a small business that sells mostly online, it covers nearly everything that matters.

What is a content marketing audit?

It is the part of a marketing audit that reviews blog posts, guides, newsletters and other content, piece by piece. On a website, that is the same work as a content audit, where every page gets kept, updated, consolidated or removed.

How often should you run a marketing audit?

Regularly, as Kotler’s definition says.1

Who should run the audit?

Kotler’s definition calls for an independent review.1 An independent view tends to notice what daily routine hides. The numbers still come from your own team, though, because only they have them.

How is it different from an SEO audit?

An SEO audit only checks how well the website can be found on Google. A marketing audit looks at every channel customers come through, and at the strategy behind them.

How much does a marketing audit cost?

The agency Web Tonic puts an audit of a single channel at $2,500 to $7,500. If several channels get reviewed, it’s $8,000 to $25,000 or more.4
