How to improve Meta and Google ROAS for SaaS

ROAS dies in two places: ads that have been seen too many times, and pages that do not match the promise. Teams then raise budget or change the bidding strategy. Aether’s 3.8× blended ROAS came from weekly creative sprints, landing variants, and geo-split tests — not from a smarter acronym in Ads Manager.

Written for: Growth leads running Meta, Google, or TikTok for SaaS or adjacent offers

ROAS is a creative and destination problem first

If frequency is high and CTR is sliding, you do not have a bid problem. If CTR is fine and cost per qualified action is terrible, you have a page or offer problem. Diagnose before you “restructure the account.”

A weekly test that sales and brand can live with

Brief three concepts. Kill two. Scale one. Ship a landing variant with the winner — never a week later. Aether had been doing monthly creative dumps; CPMs rose, ROAS fell, CAC was 41% worse than after the rebuild.

Concept, not crop: a new promise or proof, not a recolored square.
Match the page headline to the ad that won.
Split geos if audiences truly differ (Aether: UK vs diaspora).
Report blended ROAS and CAC, not only the winning ad set.

SaaS-specific caution

B2B SaaS often has long cycles. Optimize toward qualified demo or trial, not raw leads. If you cannot fire that event, you are buying cheap emails. We will not scale spend on a brochure site.

Checklist

Pull frequency, CTR, and cost per qualified action for 14 days.
Retire ads above your fatigue threshold even if they “used to work.”
Write three genuinely different concepts for the next week.
Launch at least one landing variant with the new winner.
Confirm the conversion event is the sales-relevant one.
Cap budget until the new pair (ad + page) beats baseline.

Common mistakes

Refreshing only the headline on the same visual for three months.
Sending every campaign to the homepage.
Optimizing for the cheapest lead definition.
Letting the agency own the ad account so you cannot see frequency.

FAQ

What is a good ROAS for SaaS ads?

It depends on LTV, payback, and whether you count pipeline or cash. Use payback and CAC alongside ROAS. A 3× on a low-quality lead is not a win.

Should we use Meta or Google first?

Google if high-intent queries exist and the page can win the comparison. Meta/TikTok if you must create demand and you can refresh creative weekly.

How often should SaaS creative change?

Weekly at meaningful spend. Monthly is how Aether’s previous setup died.

Can a Lagos pod run US/UK ad accounts?

Yes. Reviews sit in the London-all-day / NYC-morning overlap. You keep visibility on the account.

Do you work with an existing media buyer?

Often. We take creative + landing; they take bids. The weekly test list has one owner.

When should we stop paid entirely?

When you cannot name a qualified event or the page cannot be changed this month. Fix the destination first.
