Built for the work between the big decisions

Small tools for fiddly marketing problems

Most marketing teams don’t need another platform. They need a reliable way to handle the boring but important parts: campaign naming, tracking, analysis, interpretation, and quality checks.

I built these utilities for problems I keep running into myself. They are free to use, and the browser-based tools keep your input in your browser.

Page Evidence · Free & open source

Find your next content investigation.

A page loses clicks. New questions appear in Search Console. You need to decide what deserves a closer look.

I built Page Evidence to bring the search and analytics evidence into that decision. Inspect a page, see which queries changed, and explore the findings with an AI assistant.

Runs on your machine. Connects to your own Search Console and analytics properties.
