These answers come from the year-long archive of my previous chatbot that lived on my previous site iamnicola.ai. I’ve curated the most useful sessions—real questions from operators exploring AI workflows, experimentation, and conversion work—and lightly edited them so you get the original signal without the noise.

What is Time to First Byte and how do I improve it?
Time to First Byte (TTFB) measures how long it takes for a browser to receive the first byte of data from the server after requesting a page. It's part of Core Web Vitals and indicates server response speed. Improve TTFB by optimizing server performance, using faster hosting or CDNs, enabling server-side caching, optimizing database queries, reducing server processing time, using HTTP/2, and choosing hosting closer to users. For dynamic sites, consider server-side rendering or edge computing. Example: A site improved TTFB from 800ms to 200ms by moving to a faster hosting provider, implementing server-side caching, and optimizing database queries, improving overall page speed.
