FAQs

Which agency type should a first-time advertiser choose?
If budgets are tight, start with an automation platform to validate channels and offers. Once you see signal in CAC/ROAS, bring in an agency to scale and diversify.

How long before I see results?
You should see leading indicators in 2–3 weeks (CTR, CPC, add-to-cart, qualified leads). True efficiency (CAC stability, payback) often needs 6–12 weeks of structured testing.

Do I need influencer marketing?
If your category is visual or culturally driven (beauty, fashion, F&B), yes—provided you tie creator content to trackable landing pages and promo codes.

What’s a healthy creative cadence?
Plan weekly hook/format tests, monthly thematic refresh, and quarterly brand platform updates.

How much should I spend?
As a starting point, allocate 7–12% of monthly revenue for growth. For launches, set aside 6–8 weeks of “learning budget” before judging CAC harshly.
