- [Shopify theme performance: the 2026 playbook](https://sevsolutions.com/posts/shopify-theme-performance-2026): Lighthouse 98, INP under 150ms, LCP under two seconds — on a real Plus store with twelve apps installed and a merch team that won't stop adding Hero sections. The wins, the losses, and the audit method that finds the next bottleneck before the merchant complains.
- [BigCommerce to Shopify Plus: a 2026 migration playbook](https://sevsolutions.com/posts/bigcommerce-to-shopify-plus-playbook): Channel fees, theme constraints, the option-set tax. Why merchants are leaving BigCommerce in 2026 and what an honest Shopify Plus migration actually costs — catalog model, URL map, channel consolidation, timeline.

Fourteen A/B tests. The four interventions that won every time, the three that lost, and the four that depend — with sample sizes, lift, and what you should actually run on your store.

From an agency that has shipped twelve.
- [Shipping Shopify Functions in Rust: a complete 2026 tutorial](https://sevsolutions.com/posts/shopify-functions-rust-tutorial): Six Rust Functions in production. The cargo manifest, the wasm-size optimisation that drops binaries 60%, the JSON schema mismatch trap nobody documents, and the cold-start latency data that justifies the extra build complexity.

The Discount Function input/output contract, the BOGO traps, the tiered-pricing decision points, and the test harness that catches the schema drift the Shopify CLI doesn't.
