The 5 revenue leaks a Substack audit finds first
A Substack audit is a paid outside review of your publication that names why readers are not buying and tells you what to fix first.

A Substack audit for creators is a paid review of a live publication by someone who monetizes newsletters for a living. You send your URL, your revenue goal and your timeline. You get back a recorded video walkthrough of your publication and a written plan that says what to fix first, what to ignore for now, and what your next 90 days should look like.
I run five of these a month. In almost every publication I open, the money stops in one of the same five places.
The 5 revenue leaks an audit finds
- Nobody can tell who the newsletter is for. The about page describes the writer instead of the reader. A stranger who lands there has no reason to think the next issue is about her.
- The homepage is not doing any selling. On Substack your homepage is the page most new readers see first, and most of them are one paragraph and a subscribe button.
- There is no offer, or there are six. A reader who wants to give you money cannot work out what to buy, so she buys nothing.
- The price was picked by copying someone else. Annual pricing, the free tier and what the paid tier promises are usually the three things I change first. Here is what I charge and why.
- Nothing connects discovery to payment. Notes bring strangers in, the welcome email says hello, and then the path stops. The 6 income streams a newsletter can carry are here.
None of those five are writing problems. That is the part most people are relieved to hear, and the part that makes an audit useful, because every one of them can be fixed in an afternoon once someone points at it.
Audit, call, or done-with-you: which one you need
| Option | What you get | Best for | Price |

| Substack Setup Sprint | Four 1:1 sessions where we build the publication and the conversion path together | You want it built with you, not handed to you as a list | $1,397 |
When an audit is worth it, and when it is not
An audit pays for itself when you have readers and no revenue. If 300 people open your issues every week and nobody has bought anything, the problem is structural and an outside read finds it fast.
Skip it if you have published four times and have 20 subscribers. At that stage you do not have enough data to review. Publish for another 60 days, post on Notes, and get the free guide below instead.
Questions people ask
How much does a Substack audit cost?
Mine is $450 as a one-time payment, delivered within five business days. I take five a month so each one gets a full review of the live publication before I record anything.
What do you need from me?
Your Substack URL, your revenue goal and your timeline. Nothing else. I do the review on your live publication.
What if I have no paid subscribers yet?
That is a normal starting point. The audit then covers what has to be in place before you turn paid on, which is usually the about page, the welcome email and one offer.
Is it only for Substack newsletters?
Yes. The recommendations depend on how Substack works, including the homepage, Notes, recommendations and the paid tier settings.
What happens after the audit?
You get a download link so you can come back to the video, and a written list in priority order. Most people do the first two items the same week.
