01Will you actually hit 'Good' Core Web Vitals?

Yes — most engagements move all three CWV metrics into the green within 30 days. We use real-user data from CrUX, not just lab synthetic scores.

02How much can speed improve conversion?

Most clients see 5–15% conversion lift from speed work alone. eCommerce and lead-gen with mobile-heavy traffic see the biggest gains.

03Can you optimise a Shopify / WordPress / Webflow site?

Yes — platform-specific speed playbooks for each. Even constrained platforms can hit Good CWV with the right asset, script and caching discipline.

04Will speed optimisation break anything?

We test in staging, ship behind feature flags where possible, and monitor for 30 days post-launch. Rollback paths are documented for every change.

Yes — a senior website speed optimization specialist owns your account, with a strategist and account director backing them up. No junior handoffs.
