Check with a tool before hiring anyone
These are the first steps in every client audit I run. Now they are public — use them, no email required.
Website technical audit
Enter a URL and check first-payload body text, H1 structure, structured data, image alt coverage, sitemap and AI-crawler policy. Every finding comes with the measured number and the fix.
AI inference cost calculator
Four numbers in, monthly inference cost out. Model comparison, cache discounts and where to cut cost.
AI crawler check
See which AI crawlers your robots.txt allows. Citation crawlers and training crawlers are different — blocking both removes you from ChatGPT answers entirely.
JSON-LD generator
Fill a form and get paste-ready structured data: Organization, LocalBusiness, FAQPage, Article. No need to read the schema.org spec.
Every tool is read-only or pure calculation. Nothing is stored. If you find something worth fixing, see the services page or just write to me.
