When you sell, a buyer audits your marketing.Most owners fail before they start.

The Marketing Due Diligence Checklist is the exact list a buyer works through when they inspect your marketing: where your leads come from, what you actually own, and whether any of it keeps working after you leave. 6 categories. Score yourself before someone else does.

The problem

Buyers do not pay for a business that stops working when you walk out.

What buyers see in most businesses

  • Leads come from the owner's personal network
  • The phone rings because of one referral source
  • No email list, no rankings, nothing that transfers
  • Marketing lives in the owner's head, not in documents
  • The brand is the owner's name on a truck

What a sale-ready business shows

  • Leads from 3+ channels, none over half the total
  • An email list and organic rankings the buyer keeps
  • Documented playbooks, vendor list, and credentials
  • Marketing that runs without the owner touching it
  • A brand and reputation that stand on their own
80%
Listed businesses never sell
92%
Exits end in closure
3-4x
Multiple when owner-dependent
7-8x
Multiple when it runs itself

What it looks like

A look inside the checklist.

Category 1: Lead Sources & Channel Diversification

  • You can name every channel that produced a lead in the last 12 months, with a rough percentage for each.
  • No single channel accounts for more than half of your leads.
  • Leads keep coming from sources that do not depend on the owner's personal contacts.
  • You can show a buyer a 12-month trend, not just last month's numbers.
  • Paid channels have a tracked cost per lead, not a guessed one.

The full checklist runs through all 6 categories with 30+ check items.

Print it, work through it, and you will see your business the way a buyer does: asset by asset, risk by risk.

What's in the checklist

6 categories a buyer inspects in your marketing.

1. Lead Sources & Channel Diversification

Where leads come from, the percentage per channel, single-channel risk, and how much of it rides on the owner's personal network.

2. Owner Dependency in Marketing

Would the leads keep coming if you left tomorrow? Who holds the relationships, the logins, and the knowledge that makes marketing work.

3. Owned Digital Assets

Email list size and health, organic rankings and traffic, domain, social followings, content library, and what transfers versus what you only rent.

4. Documentation & SOPs

Documented marketing processes, playbooks, vendor list, and a clean handoff of access and credentials a buyer can actually take over.

5. Brand & Reputation

Review profile, ratings, branded search volume, and whether the brand can stand on its own or is just the owner's personal name.

6. Analytics & Tracking

GA4, conversion tracking, attribution, and reporting a buyer can verify instead of taking your word for the numbers.

The checklist shows you the gaps. Closing them is what moves your multiple. An owner-dependent business sells at 3-4x earnings. One that runs without the owner sells at 7-8x. Strong organic rankings can add 10-30% to the price, and an email list adds roughly $1 per subscriber per year of value.

FAQ

Common questions

What is a marketing due diligence checklist?+
It is the list a buyer (or their advisor) works through to judge your marketing before they buy. It checks where your leads come from, what digital assets you actually own, how much of it depends on you personally, and whether the numbers can be verified. Using it on yourself first shows you the gaps before a buyer finds them.
Who is this checklist for?+
Small business owners (roughly $500K to $2M in revenue) who plan to sell in the next few years, and buyers who want a marketing lens on a deal. If a sale is anywhere on your horizon, the earlier you run this, the more time you have to fix what it surfaces.
Why does marketing affect what my business sells for?+
Because buyers pay for cash flow that keeps coming after you leave. Marketing that runs on your personal contacts and lives in your head does not transfer. Owner-dependent businesses tend to sell at 3-4x earnings while businesses that run without the owner reach 7-8x. Strong organic rankings can add 10-30% to the price.
How long does it take to work through?+
About 30 to 60 minutes to go through honestly. The point is not to score perfectly the first time. It is to find the gaps, then decide which ones are worth fixing before you list.
Is this only useful right before a sale?+
No. The best time to run it is two to three years before you sell, because most of the fixes (building an email list, diversifying lead sources, documenting processes) take time to compound. Running it early is how you actually move your multiple.
What do I do after the checklist?+
Take the free Exit Marketing Score for a graded read, grab the $17 toolkit if you want the templates to fix things yourself, or book the $350 audit and I will review your marketing the way a buyer would and hand you a prioritized plan.
Does an email list really add to valuation?+
A healthy, owned email list is one of the few marketing assets that transfers cleanly to a buyer. As a rough industry rule of thumb, a list adds about $1 per subscriber per year of value because it produces predictable revenue the new owner inherits.
Is it really free?+
Yes. The checklist is delivered to your inbox at no cost. The paid options exist for owners who want help closing the gaps it finds, but the checklist itself is free.
