Where Should Your First Ad Money Go? | Decide by Measured RPS

Revenue has stabilized and you're considering your first ad campaign. Google or Meta? This is where most people decide from generalizations and impressions — "everyone says Google," "our product is Instagram-friendly."

But your pre-ads site already holds the evidence: per-channel RPS of the traffic you're getting without ads.

"Which door brings buyers" is already measured#

From the sample store's real 30-day data, the main organic rows by per-channel RPS (revenue per session):

For this store, people who arrive from search buy (Google ¥390, Yahoo ¥455). People from social don't (X ¥0). With that measurement in hand, the first candidate for ad money is search ads — your own data proves buying intent lives on the search surface. Starting with social ads instead would mean knowingly betting against your organic evidence — fine, but do it small and call it what it is: a hypothesis test.

The point is that the Google-or-Meta answer differs per site. Your table may rank differently from the sample's. Decide from your own table instead of the industry's folklore — that's the entire method.

After launch, the loop closes on the same screen#

Bring your ad spend into RevenueScope and the channel rows gain ad spend — and you can check "is the ad actually working?" by lining it up against the corresponding channel's revenue. For the quitting decision, what happens if you stop your ads.

RevenueScope shows the buying doors before you spend a yen

Per-channel RPS is bot-excluded, measured, and accumulating before you spend anything. RevenueScope sorts your pre-ads organic traffic into buying doors and non-buying doors, so you can start your first campaign from a measurement-backed hypothesis — the simplest way to waste less in the opening weeks.

FAQ#

Q. My organic traffic is still small and RPS is unstable.

Channels with sessions in the low double digits swing on a single order. At that stage, solidifying the growth-stage numbers usually beats ads on cost-effectiveness.

Q. What if I want to advertise on a channel not in my table (like TikTok)?

Any door without measurement is a hypothesis start, whichever you choose. Use the nearest organic analog (for social, your X or Instagram organic numbers) as a reference, spend small, and buy yourself a measurement.
