Chci PPC: an educational site in seven languages
An educational hub for PPC: it gathers people looking for information, gives them honest content and sends them on to the agency and the tool. Technically it is the template we build content sites on.
- In short
- Seven languages with the language in the URL, localised article slugs and hreflang; every article has a stable key across languages.
- The calculator models ad response with a power curve and admits when the result is an extrapolation outside the calibrated range.
- All pages are statically pre-rendered, with a JSON-LD graph, OG images generated per article, RSS and llms.txt.
What is interesting technically
- Localised slugs. Path segments are uniform English, but article slugs are translated because they carry SEO weight. Every article has a stable key that holds translations and hreflang together.
- Typed dictionary. Czech is the source of truth and the dictionary type is derived from it, so a missing key in a translation is caught by type checking, not in production.
- Editorial checks as tests. A script watches for links to non-existent slugs, SEO title lengths and sources without a note on their limits.
- Calculator model with tests. Marginal CPA, profit optimum and break-even are computed from a power curve; above three times the reference budget the UI admits extrapolation instead of showing an untrustworthy number.
Why we do it
A site that answers questions becomes a source for search engines and language models alike. Enquiries then come from people who already know what they want.
