The method

Field and lab

What your real visitors experience, and what the bench test says. Both, because they do not measure the same thing.

By real gain

What slows things down, by how much, and what each fix costs. The report reads in order of impact.

You stay free

I write the report so your team can apply it, or I can, or no one. It belongs to you.

If a rebuild is the right answer, I say so and I price it. The build tiers are online.

Frequently asked questions

What exactly do I get?

A written report ranked by measured impact: what slows things down, by how much, and what each fix costs. The Complete tier adds a video debrief and an action plan.

Do you apply the fixes?

Not in the audit itself, which stays a measurement. The Fixes tier implements them on your existing stack and measures the before and after gap. You can also hand them to your own team: I write the report for that.

Does the site need rebuilding?

Often not. An audit exists precisely to tell whether what hurts can be fixed on the existing build or whether the structure is at fault. If a rebuild is the right answer, I say so and I price it. You stay free to hand it to anyone.
