Is Apple Ads worth it for a small app? The arithmetic

Apple Ads is worth it for a small app when an install costs less than a download earns, on the terms where your page already converts, in the countries where the price tier supports it. That is three numbers, and all three are yours to find before you spend anything. Below is the arithmetic with illustrative figures, the two ways it goes wrong, and the one benefit the campaign report never shows you, which a daily rank tracker does.

The arithmetic

Suppose a download earns 5 over three months, after the store's share, averaged across everyone who downloaded. Suppose the page converts a quarter of ad taps into installs. Then:

• An install is worth 5. The ceiling is below that, say 3, to leave room for error.
• A tap is worth 3 divided by 4: 0.75. Bids start below that.
• A campaign spending 300 at those rates buys about 100 installs, which earn about 500 over three months. Worth it.

Change one number and the answer changes. At a conversion of one in ten, a tap is worth 0.30, and most terms will cost more than that; the fix is the product page, not the budget. At 2 per download, the ceiling drops to about 1.20 per install, and only the cheapest, most relevant terms qualify.

Where it goes wrong, first way: the wrong terms

Bidding on high-volume terms held by large apps. The taps are expensive and the searcher wanted the large app. Install cost blows past the ceiling in a week. The fix is to advertise only the terms your app already ranks for organically or is close on; those convert like your organic traffic does. The first list.

Second way: the wrong country

The same term costs the same in two countries and earns half as much in one, because the price tier is lower or renewals are weaker. A single global campaign hides this. Split by country, set a ceiling per country from that country's proceeds per download, and let the countries that cannot support a ceiling stay organic. Why the ceilings differ.

The benefit the report does not show

Installs from a term tell the store the page is relevant to it. On terms where you were organically close to the first screen, a campaign often moves the organic rank up, and the organic installs that follow are free. The campaign report attributes none of them. A daily tracker does: the organic rank on each advertised term, the week before and the weeks after, per storefront. For our own app Escape, reading that lift is how we decide which terms to keep advertising and which have been won organically and can be cut.

The decision

Run a two-week test on the terms you rank for, in the one country with the highest proceeds per download, with a ceiling from your own numbers. Read three things at the end: cost per install against the ceiling, taps against installs, and the organic ranks on those terms before and after. If the first is under and the third moved, it is worth it. If the second is bad, fix the page before spending again.
