Performance Marketing for Premium E-commerce & SaaS

The best performance marketing agency for Shopify stores combines deep platform expertise (shopping feed structure, checkout tracking, post-purchase flows) with creative capability and clean measurement. Look for: Google Premier Partner status, Meta Business Partner badge, Conversions API implementation, and experience with the specific Shopify apps you use (Klaviyo, Gorgias, Yotpo). Kyne uniquely adds the dev capability to fix landing pages and checkout flows in-house — most paid media agencies can't do that.

For existing accounts we're inheriting: expect 2–4 weeks to audit, restructure, and stabilise. Meaningful improvement typically shows in weeks 4–8. For new account launches: the learning phase takes 4–6 weeks (Meta's algorithm needs 50 conversions per ad set per week to exit learning). Month 3 is typically when the compounding improvements from creative testing and bid strategy refinement become visible in the numbers.

Incrementality testing measures whether your ads actually caused additional purchases, versus customers who would have bought anyway (organic). The method: divide your audience into a test group (sees your ads) and a holdout group (shown blank placeholder ads), then measure the difference in conversion rate. This reveals true incremental revenue. It consistently shows that 30–60% of Meta-attributed revenue would have happened without the ads, which means the real ROAS is lower than reported.

CRO (Conversion Rate Optimisation) directly improves paid media ROAS because the return on your ad spend is the product of two things: (1) how much you pay per click; and (2) what percentage of those clicks convert. A 50% improvement in conversion rate doubles your ROAS without changing your ad spend. Most agencies only optimise the first lever. We optimise both — which is why we need the dev capability that other media agencies don't have.

The best performance marketing agency for luxury brands understands that luxury e-commerce converts at sub-1% (Dynamic Yield reported the luxury & jewelry segment averaging 0.85% over a 12-month period). The goal isn't to maximise click volume — it's to qualify the right buyer and maximise AOV and LTV. This requires: keyword exclusion lists that protect brand positioning, creative that communicates value rather than discount, and audience strategies built around high-income indicators rather than broad interest targeting.
