The best time to launch a product is when demand for its category is starting to rise. Launch ads placed then reach people who have already begun to look, so they meet interest instead of trying to create it from scratch. Your ship date and your launch date can be different days, and often they should be.
How do most people pick a launch date?
Most people pick a launch date one of two ways: they ship when the product is ready, or they choose a date ahead of time. With the first, the build is done, the signup page or store listing goes live, and the launch ads start the same day. With the second, the date is often a round one, such as the first of a month or a date promised to investors or early customers.
Both methods answer the question "when can we be done?" That is a fair question for building a product. Launch ads depend on a different one: when will the people who buy this product start looking for it?
Sometimes the two answers line up by luck. Often they don't, and the launch goes out into a quiet month. Sales come in slower than hoped, and afterward it is hard to tell whether the product, the ads or the timing was the problem.
| Approach | What it answers | What it misses |
|---|---|---|
| Ship when the product is ready | When the build is finished | Whether buyers are looking that week |
| Pick a fixed date ahead of time | When everyone can prepare for the launch | Whether demand is rising on that date |
| Launch into a demand window | When buyers start looking for the category | Needs the product ready, or released quietly, before the window opens |
Why do launch ads land differently when demand is rising?
Launch ads land better when demand is rising because more of the people who see them already need the product that week. An ad reaches a person at one moment. If that person needs your kind of product this week, the ad is useful to them. If they won't need it for months, it is something to scroll past, however good the creative is.
When demand for a category is rising, more of the people you reach are in the first group. They search for the category, click through to compare options and buy sooner. When demand is flat, most people you reach are in the second group, and your ads have to create a need before they can sell anything.
With invented numbers, the arithmetic looks like this. Say $1,000 buys about 1,000 clicks. If demand is rising and 3 in every 100 visitors buy, that is 30 orders. If the category is quiet and 1 in 100 buys, that is 10 orders. The product, the ads and the spend are identical in both cases. Only the week moved.
Clicks can cost more when demand rises, because other advertisers want the same buyers. So judge a launch by cost per sale, since cost per click alone can mislead you in either direction.
A launch also has effects past the first week. Early buyers tell other people about the product. Ad platforms learn from early conversions, so a launch that converts gives their bidding more to work with. A launch that stalls leaves you with little to learn from and a harder second push.
What is a demand window?
A demand window is a stretch of time, with a start and a stop, when interest in a category rises because several things outside your company build up at once. It is different from a holiday or a fixed date that every advertiser already plans around. Windows come from changes in people's lives and in businesses, and their dates move from year to year.
Take a video doorbell. Home sales climbing for a third month means a wave of new owners moving in, and new owners replace the doorbell and the locks in their first weeks. A doorbell launched into that run meets buyers who have a reason to act now.
Software works the same way. When hiring rises month over month, companies shop for onboarding software, because each new hire needs accounts and paperwork set up before day one. When new business registrations climb for several months, first-time founders look for invoicing software before their first customers pay them.
| Product | What is building up | Why a buyer acts now |
|---|---|---|
| Video doorbell | Home sales climbing for a third month | New owners replace the doorbell soon after moving in |
| Dash cam | Used car sales rising for several months | New owners add a camera in the first weeks with the car |
| Onboarding software | Hiring rising month over month | Each new hire needs accounts and paperwork ready |
| Invoicing software | New business registrations climbing for several months | Founders need a way to bill their first customers |
Each of these windows closes, too. Home sales level off, hiring slows, and the pool of people with a fresh reason to buy shrinks. Launch ads that keep running past the stop are back to working against flat demand.
How do you find a window where people are starting to look?
You find a launch window by naming the event that makes a buyer need your product, then watching for the build-up that makes that event more common. The steps below work for a physical product or for software.
Start with the buyer's trigger
Write down what has to happen before someone needs your product. A doorbell buyer just moved. An invoicing software buyer just started a business. Be specific here. "People who care about home security" is an interest, while "people who closed on a house last month" is a trigger you can time.
Find what makes the trigger more common
Triggers become more common when something larger builds up. More home sales mean more people moving. More hiring means more new staff to onboard. Look for the build-up behind your trigger and check whether it is rising, flat or falling. You want movement that keeps going for several weeks or months, because each month of it adds more people with the trigger.
Check the early signs in your own accounts
Your own data can confirm a window as it opens. Watch the search terms in your ad accounts, visits from people who have never heard of you and signups to a waitlist. If these climb while the outside build-up rises, people have started looking.
The catch is timing. Your own numbers move after the window opens, so they confirm a window more than they predict one. If you wait for them alone, part of the window is gone by the time you launch. Verdius dates the window from the events behind it, so you know the start before your own numbers move.
Set a start and a stop
Give the window real dates, such as April 28 to May 4 for a short one or May 19 to June 30 for a longer one. Launch ads start at the opening. Decide in advance what closes it: the build-up levels off, or your cost per sale climbs back to where it sat before. Without a stop, a launch push slowly turns into an always-on campaign.
Know who is in the window
The people entering a window share traits. New homeowners fall into a narrower band of ages and incomes than the general population. Companies that are hiring fast have people in specific roles doing the buying. Describe that audience in the terms ad platforms already use, such as age, income, location and interests, so you can build it in Google Ads, Meta, TikTok or LinkedIn before the window opens.
Verdius does these steps for you. For each product it finds windows with a start and a stop, ranks them against each other, and lists the events behind each one along with the audience to reach. It sends an alert when a window opens and again when it closes, and you run the launch ads yourself. You can read how the windows are found for more detail.
What should you do if the product is ready before the window?
If your product is ready before the demand window, ship it quietly and hold the main launch ad spend until the window opens. A finished product doesn't need to sit on a shelf. Split the ship date from the launch date, and use the gap.
Release it quietly first. Open it to a waitlist, existing customers or a small group of early users. You get real feedback and can fix what they find before the wider launch.
Test your ads at low spend. Run a few variations with small amounts to learn which message and image get clicks and sales. When the window opens, you put money behind ads that have already worked.
Build the audiences ahead of time. Set up the targeting in each ad platform so the launch push can start on the day the window opens. Verdius gives you each window's audience by age, income, location and interests, so the setup can happen weeks ahead.
Collect proof. For software, early users become case studies and quotes for the signup page. For physical products, early orders show which variants sell, so you can stock up before buyers arrive in larger numbers.
Hold the main launch spend. The money you would have put into a launch against flat demand is still there when people start looking.
If the next window is a long way off, look for a smaller one sooner. Many products have more than one reason to buy them. A dash cam sells to new car owners and also to people who just took up delivery work, and those two groups rarely start looking in the same weeks.
What if the window opens before the product is ready?
If the demand window opens before your product is ready, either ship a smaller version that does the core job well or finish the product and wait for the next window. Don't rush a broken product into a busy window. A bad first experience then reaches more people than it would in a quiet month.
Avoid launching into the last days of a window, since the audience is shrinking just as your ads start. Verdius gives every window a stop date, so you can see how much of it is left.
Does launch timing matter if you are only boosting one campaign?
Launch timing matters even more when you are boosting one campaign, because you have one shot at the launch week. A large company can run several launch pushes across products and learn from each. If you are putting a few hundred dollars behind a single campaign, the week you pick is one of the few choices you control that changes how many people are ready to buy. There are more examples of launch timing for different products.
What tool tells you when to launch a product?
Verdius is software that predicts when demand for a product will rise and who to target then. It finds the launch window, so you can set the launch date around it.
For each product it gives you:
- Optimal windows to run ads, each with a start and a stop, ranked against each other
- The events behind each window
- The audience to reach, by age, income, location and interests
- Alerts when a window opens and when it closes
Verdius connects to Google Ads, Meta, TikTok, Reddit, Snapchat, LinkedIn, Microsoft Advertising and ChatGPT Ads, plus Google Analytics and Search Console. It only reads that data, and you run the launch ads. The pricing page shows what each plan covers.
How is launch timing different from picking the best day to run ads?
Picking the best day and hour is fine tuning inside a window, while launch timing decides whether buyers are looking at all. Once you know the window, the guide to the best time to run ads covers the smaller adjustments.
