For consulting: describe the system, the metric that is failing, and what you have already measured. “Our LCP is 4.2s on mobile and here is the waterfall” gets a reply; “can you make our site faster” does not.

What I do not do

• Guest posts and paid links. The answer is no, and it will stay no.
• Anything that requires shipping a tracking script to readers of this site.
• Rewriting a post to include a client’s product without saying so.

Comments on individual posts are open, moderated, and answered when they add something. The form never asks for an account.
