Performance is a feature you can sell

When a stakeholder asks why they should pay for performance work, the honest answer isn't 'because slow is bad.' It's 'because here is the revenue we're leaving on the table.'

Instrument the funnel

We connect Core Web Vitals to the conversion funnel so improvements show up where the business looks. Once a product owner can see that a 1.9-second drop in load time moved checkout completion, the conversation stops being about engineering taste.

• Measure real-user metrics, not just lab scores.
• Tie each metric to a business outcome you already track.
• Fix the biggest offender, prove the lift, repeat.
