Guides
Short answers to the questions behind a website
Each guide opens with the answer in two sentences, then shows the working. Written from the code that runs the product, with the date it was last checked.
Web analytics
Is ChatGPT sending you visitors?
Look for visits whose referrer is chatgpt.com or one of the other assistants. Apps that strip the referrer arrive with none, so whatever you count is a floor.

Web analytics
Do you need a cookie banner for analytics?
Not for measurement that stores nothing on the visitor's device and keeps no IP address. Whether your site needs one still depends on everything else it loads.

Web analytics
Which AI crawlers should you let in?
Some read to train a model, some to build an answer index, and some fetch a page because a person asked. Refusing the first kind keeps you in the answers.

Glossary
The words these pages use, said once and plainly
Every term, with what it means hereNumbers come from the code
A limit or a retention window is read from the setting that enforces it, so a guide cannot go on quoting last year's figure.
Dated, and sourced
Every guide shows the day it was last checked, and links the pages of other companies it describes.
No stories we cannot show
No invented customers, results or quotes. Where an example is needed, it says it is one.
