I'm John Patzi. I run four WordPress sites on my own VPS — server, CDN, cache, security and content — and **I did every one of these fixes to my own sites before offering them to anyone.**

## Where my checks come from

**Not from a course.** From things that broke in production and cost me hours to find.

A cache layer that silently ignored my own rules, so a correct fix stayed invisible for half a day. A CDN rule that shipped switched on and returned 403 to Googlebot while my robots.txt welcomed everyone. Every pretty URL on a new site returning 404 **without writing a single error to any log** — and [the first explanation I gave for it, which turned out to be wrong](https://visibleorigin.com/openlitespeed-404-logformat/).

Every one of those is now a check I run on someone else's site in two minutes.

## How I work

**I measure before I conclude, and I show the measurement.** The rules I follow when measuring a site I do not own are published in [How I measure](https://visibleorigin.com/how-i-measure/). Every finding in a report carries the request and the response that produced it, so you can repeat it yourself and disagree with me if I am wrong.

**I tell clients when something is not worth their money.** The framework I audit against has controls that require APIs and OAuth endpoints a content site will never have — chasing them buys a number, not a visitor, and I say so in the report.

## What I actually do

WordPress, and server-level work on Apache, Nginx, LiteSpeed and Cloudflare: cache rules, WAF, DNS, TLS, DNSSEC, structured data, and the newer layer of llms.txt, Content Signals and agent discovery. One write-up walks through [a DNS record I published, and the two I rejected because they would have been false](https://visibleorigin.com/dns-aid-svcb-record/).

Based in Chile. I work in **English and Spanish**.
