WarsawJS: JavaScript Community Meetups in Warsaw

It's Friday evening, and your deploy to prod just went red. Is it a real bug or just a flaky test?

For several months now, we at Coople have had Claude Tag as our on call buddy in Slack. It finds out what's broken in our production, and comes up with a fix when one is needed. It also checks every new release, web and mobile, once it goes live.

I'll share real stories: what worked, what didn't, and the lessons we've learned.

More and more people get their answers from ChatGPT, Perplexity, Gemini and Google AI Overviews instead of a page of ten blue links. If your product, docs or blog are not the source these engines quote, you are invisible.

GEO (Generative Engine Optimization) is about becoming that source. E-E-A-T (Experience, Expertise, Authoritativeness, Trustworthiness) is how Google, and increasingly the models, decide whom to trust.

K MAG doubled its visibility in one year. Using it as a case study, I'll show what we changed in content, structure and technical setup, what moved the needle and what didn't. You'll leave with a practical checklist for developers: structured data, authorship signals and the rest of what makes both search engines and LLMs take your site seriously.
