Will my Magento store get faster after the optimization?

Yes, measurably and in writing. Every Full Optimization project ships with a Lighthouse 90+ guarantee and a target of 50%+ TTFB reduction. We capture before/after metrics on staging every day during the project (Lighthouse, WebPageTest, RUM if you have it) so you can see the curve flatten in real time. If we miss the agreed targets at go-live, we keep tuning at no extra charge until we hit them. The audit-only tier doesn’t include the fix, it’s a diagnose-and-prioritise report you can hand to any developer to execute.
