Recommended Minimum Budgets (and When Not to Run Remarketing)

Quick answer

We recommend at least 20 per day in total on Meta. Below roughly 15 per day on your new customer campaign, leave remarketing switched off: there are not enough new visitors arriving to remarket to, and the remarketing budget is too small to convert. If your total daily budget across all advertising is under about 70, run Meta only. All figures are in your ad account currency.

Why there is a minimum at all

Meta's algorithm needs roughly 50 optimization events in a rolling 7-day window to exit the learning phase and deliver predictably. That is arithmetic, not opinion:

daily budget × 7 ÷ your cost per purchase = weekly conversions

If that number lands under 50, the ad set sits in Learning Limited indefinitely. It can still make sales, but performance stays volatile and the algorithm never gets enough signal to improve. Full detail: Understanding the learning phase.

At very low budgets the problem compounds. Spend is spread thin across a broad audience, the algorithm explores instead of exploiting, and you end up paying learning-phase prices permanently. Creative quality cannot fix this. Neither can waiting.

Recommended minimums

These are floors, not targets. They are the level at which the platform can begin working properly, not the level at which it works best.

How the split between campaigns is decided

You do not need to divide the budget yourself. Agency AI sets the split between your new customer campaign and your remarketing campaign based on three things:

• The target audience for your brand
• Your average product price points
• The size of your product library

A store with a large catalogue and a low average order value needs a different split from a store selling a handful of high-ticket items. The algorithm weights accordingly, and adjusts as your data builds.

When not to run remarketing

Remarketing only works if there is somebody to remarket to. It shows ads to people who already visited your store, so its audience is built entirely from the traffic your new customer campaign generates.

Two things go wrong at low budgets:

1. The pool is too small. A new customer campaign running at 4 per day sends very few people to your site. There simply are not enough recent visitors to build a workable remarketing audience.
2. The budget is too small to convert. A remarketing campaign at 1 per day will not accumulate enough events to optimize. It spends, but it rarely closes.

Get the top of the funnel working first. Once your new customer campaign is running at 15 per day or more and sending consistent traffic, remarketing has something to work with and becomes one of the most efficient parts of the account.

Note that remarketing also carries a separate rule about creative type. Dynamic catalog ads are the default there for good reason. See What Agency AI builds for you.

Changing your budget

Two ways:

• On the Manage Ads page, edit the daily budget directly.
• Tell the AI Strategist what you want the budget to be and it will apply the change for you. See Meet your AI Strategist.

One caution. A budget change larger than 20 percent in a single edit resets Meta's learning phase and costs you the progress the algorithm has made. Step increases up in stages rather than doubling at once. Agency AI caps its own increases at 20 percent per cycle for exactly this reason.

When to increase

Raise the budget when your ROAS is at or above target and stable over a 7 to 14 day window, not on a single strong day. Daily swings of 20 to 50 percent are normal and are not a signal. If you are still inside the learning phase, wait.
