+Meta Ads or TikTok Ads, which one first in 2026?
If your ICP is 30+ and the product is rational/functional, start with Meta. If the ICP is 16-34 and the product is visually strong or social-driven (fashion, beauty, gadgets, food), start with TikTok. The 2026 rule I keep seeing: new DTC e-commerce launches go to TikTok first because CPM runs 30-50% cheaper and the algorithm learns faster with native creative. Established brands keep Meta as their base and use TikTok as an amplifier.
+Which has lower CPM in UK/IE in 2026?
TikTok Ads in UK/IE typically run £2.50-£7 CPM vs Meta £5.50-£12. TikTok CPC sits at £0.12-£0.55 (Smart+/PMS), while Meta runs £0.25-£1.10 on B2C. Important caveat: low TikTok CPM does not mean low final cost. Checkout CVR is often 40-60% lower than Meta because purchase intent is lower. What you save on CPM you can lose on CVR.
+What demographics should drive the channel decision?
TikTok UK/IE in 2026: roughly 60-65% of users are 16-34, heavily urban. Meta (Instagram + Facebook combined): age skew is 25-54, more evenly distributed geographically, with Facebook still strong in 45+. If your product targets 40+, TikTok feels thin (audience exists but is shallow). If it's Gen Z + urban millennials, TikTok wins.
+Spark Ads vs Advantage+, how to decide?
Spark Ads (TikTok) amplify an existing organic post, they keep social proof (likes/comments), look native, and typically pull CTR 2x higher than standard Brand Content. Worth it any time you have UGC or a creator partnership. Advantage+ Shopping (Meta) is an algorithmic black-box campaign without manual segmentation, works very well with 50+ SKU catalogues and a healthy pixel history. They aren't equivalents, they're complementary patterns.
+Which one fatigues creative faster?
TikTok fatigues much faster, the algorithm is For-You-Page by nature, repetition kills CTR within 5-10 days. On Meta, top creatives can run for 4-8 weeks. Practical implication: TikTok demands 4-8 new creatives a month for a serious DTC brand. Meta can tolerate slower rotation (2-4/month) if the library is healthy. Without continuous creative production, TikTok doesn't scale.
+What creative format works on each?
TikTok demands vertical 9:16, raw look, native audio (trending sounds), 15-30 seconds, hook within the first 1.5s. Don't use a marketing voice-over, use on-screen text and casual language. Meta accepts vertical (Reels) plus square 1:1 (Feed) and 4:5 (Feed mobile). You can be more polished, image stills still work. Trying to use Meta creative on TikTok is the most common 2026 mistake, performance drops 60-80%.
+Attribution: which one is more opaque in 2026?
TikTok remains more opaque than Meta in 2026. TikTok Pixel + Events API work, but view-through reporting is generous and the algorithm tends to over-claim conversions. Meta Conversions API + EMQ ≥8 gives more defensible signal. Recommendation: use GA4 or an MMP (e.g. Triple Whale, Northbeam) as a neutral arbiter, trusting either platform's native reporting 100% is a recipe for misallocation.
+What budget split makes sense for DTC e-commerce?
Heavily dependent on niche. Fashion/beauty for Gen Z+Millennials in UK/IE in 2026: typical split 55-65% Meta / 30-40% TikTok / 5-10% Google brand. For more mature DTC or ICP 35+, Meta goes up to 75% and TikTok drops to 15-20%. New brands launching in 2026 sometimes start at 50/50, TikTok as primary acquisition, Meta as retargeting + lookalikes. No universal answer, only 60-90 day tests with dedicated creative.
