Frequently Asked Questions

What CPM ranges should I expect in 2026 by platform?

Meta (Facebook/Instagram) typically runs $8-20 CPM for B2C. LinkedIn runs $30-80 CPM but targets buyers. TikTok runs $5-12 CPM with younger audiences. Google Display is $2-8 CPM but quality varies wildly. Use these as benchmarks; your CPM will vary 2-3x based on targeting and creative.

Which platform has the best attribution in a post-iOS 14 world?

LinkedIn and Google both have strong first-party attribution because logged-in users persist across sessions. Meta's attribution is still rebuilding post-ATT; expect 20-40% under-reporting on direct-response campaigns. Server-side tracking via Conversions API is now table stakes on Meta to close the gap.

What's a realistic test budget before a platform is "proven" for my business?

Plan $5-15K per platform per test, spent over 4-6 weeks, with at least 2-3 creative variants. Below this, statistical noise dominates and you'll declare false winners. Most businesses that test 4 platforms with $1K each learn nothing useful.

Where do most SMBs waste ad dollars?

Running the same creative across Meta and TikTok. TikTok rewards native UGC-style content; polished Meta creative flops there. Platform-native creative typically drives 30-70% better ROAS than cross-posting. Budget separate creative production for each platform or skip platforms you can't resource.
