A Billion Dollars in Ad Spend Taught Us One Boring Thing We have watched over a billion dollars get spent on ads for online stores across the last decad...
We have watched over a billion dollars get spent on ads for online stores across the last decade. Every category you can think of. And after all of it, the biggest lesson is almost embarrassingly plain. This is for any store owner who thinks the answer to slow growth is something clever, something new, or something they have not learned yet.
Do more of what already works.
That is it. That is the whole lesson. We spent ten years and a billion dollars to confirm the thing your grandmother could have told you for free.
The stores that grow are not the ones running the smartest campaigns or launching the freshest products every few weeks. They are the ones who found the handful of products people actually want, and then put real money and attention behind those, over and over, longer than felt comfortable. The winners are boring. They just do not look boring from the outside, because the outside only sees the growth, not the quiet repetition that made it.
Different stores, different products, different owners. The pattern held every single time.
About 20% of a store's products drove about 80% of the revenue. Not sometimes. Almost always. A denim style, a graphic tee, a home candle, a kids' pajama set, a specific pair of sandals. A small group of products quietly carried the whole business while the owner spent most of their energy on the other 80% that barely moved.
And here is the part that surprised us early on and stopped surprising us around dollar number fifty million. The winning ad was rarely the new one. It was the one that had been running for a while, quietly working, that the owner almost turned off because they were bored of looking at it. The founder had seen that ad two hundred times. The customer had seen it once, in a scroll, between a hundred other things. What felt stale to the person who made it was brand new to the person seeing it.
So the ad that should have gotten more money got turned off, and the shiny new one that felt exciting got the budget instead. The exciting one usually did worse. Every time we let the boring winner keep running and fed it more, it kept paying off.
If the lesson is this simple, why does almost nobody follow it?
Because doing more of what works feels like you are not doing enough. It feels lazy. There is no new launch to announce, no fresh idea to be proud of, no busywork to make you feel like a real business owner. Going deeper is quiet. Going wider feels like progress, because there is more to do, more to talk about, more to post.
But more activity is not more revenue. We have the receipts on that one. The stores adding new categories every quarter, chasing trends, reinventing the brand every few months, they were usually the ones stuck at the same number year after year. The stores doing fewer things on purpose, with more conviction, were the ones climbing.
Boring is not the price you pay for growth. Boring is the growth.
The trouble is, doing more of what works requires you to actually know what works, and then act on it fast. Both of those are harder than they sound.
Knowing what works means watching your numbers closely enough to spot the quiet winner before you get bored and kill it. Most owners are not staring at their ad account all day, and honestly they should not have to. That is not why you started a store. You started it to sell a thing you believe in, not to become a full-time ad watcher.
Acting fast means catching the moment a product starts moving and putting money behind it right then. Not Monday. Not after the weekend. Now. A product that starts selling on a Saturday morning does not wait politely for someone to notice on Tuesday. And the flip side matters just as much. When one of your winners is about to sell out, the ad needs to ease off before you are paying to promote something nobody can buy. The Federal Trade Commission's guidance on truthful advertising is a good reminder that promoting what you cannot actually deliver is a problem worth avoiding, and running out of stock mid-ad is the sneaky version of exactly that.
This is the whole reason we built Lenny. Not to be clever. To do the boring thing well, all day, every day, including the Saturday you are out at the farmers market on 12th South and the holiday weekend when your marketing person is up at the lake. Lenny watches which products and ads are quietly working, tells you in plain English what to put more behind and what to ease off, and lets you make the call with one click. It knows your stock, so it eases off before you sell out. No Ads Manager. No guessing.
You do not need a breakthrough. You need to find the few things already working and keep doing them, consistently, for longer than feels interesting.
That is the lesson a billion dollars taught us. It is not exciting. It was never going to be. But it is true, and it is the reason some stores grow while others stay busy. The boring path is the one that compounds. We built Lenny to walk it with you so you do not have to watch every minute of it yourself.
