About

A blog about the machine that decides what you see

Tech Knows You is a small, independent publication about online advertising — the trillion-dollar system of auctions, profiles and predictions that chooses most of what appears in front of you.

What this is

One beat, covered properly. The essays explain how targeting, auctions and attribution actually work; the glossary translates the industry's jargon into plain English; the letters desk keeps the conversation two-way. The landing page carries the site's one interactive exhibit: the four live ads the algorithm picks for you as the page loads — the machine we write about, caught in the act.

How it's funded (the short version)

By advertising, on purpose. The four ad slots on the landing page are served by Google AdSense and are the only ad units anywhere on the site. Essay pages carry none. Nothing auto-refreshes, and nothing on this site asks you to click or view an ad. The full, checkable version of this — what we earn, what we will and won't do for revenue — is a published essay: How this site makes money. It doubles as the site's honesty policy.

Who writes it

Tech Knows You is written and edited independently, in a single editorial voice — bylined “the editor.” It is not affiliated with, endorsed by, or funded by Google or any advertiser beyond the arm's-length ad slots described above. When an essay touches the hand that feeds (it does), that gets said in the text, not hidden under it.

Corrections

Confirmed factual errors are fixed in the essay itself with a dated note, and material corrections are acknowledged in the letters column. The load-bearing numbers — like the landing page's $25,367-a-second counter — have their methodology published and their anchors revisited annually. Spotted something wrong? [email protected].

What we never do

Colophon

Hand-built static HTML and CSS — no framework, no build step. Set in Fraunces (display and prose) and Space Grotesk (everything else), with the numbers in your system's monospace. Hosted on Cloudflare Pages. The design is warm paper, ink, one ultramarine, and one highlighter — because a site about attention shouldn't have to shout for yours.
