My background story, and the reason NotiDuck verifies observable website behavior after deployment instead of stopping at a basic uptime response.
A 200 OK was not enough for the portfolio of websites I operated. It confirmed that a server answered, but not whether a deployment had changed the experience or the page itself.
I built NotiDuck to verify observable public web behavior after deployment. It checks uptime, performance, SEO signals, and machine-readable page signals, then presents the result in a live shared report.
This is verification of the deployed result. It is not a promise about search engines or AI systems.
My first website went live in 2001. It was built with drag and drop, and is no longer online, which is probably for the best.
I moved from those early tools to WordPress, then into Linux and self-hosting. Running websites directly taught me to care about what happens after code leaves a development environment.
My education combines robotics and automation engineering with international sales and marketing. That gives me both a systems view of how software behaves and a practical view of how products are explained and adopted.
My Politecnico di Milano thesis is relevant background for event detection and learning normal behavior in complex systems. That perspective informs how I think about meaningful changes in monitoring data, without turning the thesis into a claim about product outcomes.
I operate a portfolio of websites and tools within GIJA HUB MB, alongside other people in the business. NotiDuck began as monitoring for my own sites and evolved as those sites gave me real deployments to inspect.
Beyond a basic HTTP success response, NotiDuck can check DNS, TLS, response timing, Lighthouse results, page structure, metadata, accessibility signals, and machine-readable interfaces. These checks help show what reached the public web, not just whether a request returned successfully.
Dogfooding means I use the same workflow I describe: deploy a change, inspect the live result, and address issues that the checks expose.
As my work moved from basic uptime toward SEO, GEO, and AEO concerns, I became more interested in the technical conditions that make a page usable by people, crawlers, and software agents.
NotiDuck measures observable technical and page signals that can affect access to a site, including performance, structure, metadata, and machine-readable interfaces. It does not measure model training data, model answers, rankings, brand mentions, or citations.
I have grown organic traffic on my own sites without paid ads. That is personal experience, not a guaranteed NotiDuck outcome. Search visibility and answer-system behavior depend on many factors outside a monitoring tool.
When I use coding agents, the loop is straightforward: an agent produces changes, I deploy them, NotiDuck checks the live result, and I inspect the report.
If something needs attention, the workflow is fix, deploy again, and check the same live shared report. The agent can produce code and configuration changes. NotiDuck verifies the public result after deployment. Those are separate jobs.
"A 200 OK tells me that a server answered. It does not tell me that the deployment is healthy for people, crawlers, or software agents."

Lars built NotiDuck after finding that a 200 OK response did not tell him whether a deployment had affected performance, SEO signals, page structure, or other observable aspects of a public website.
NotiDuck checks observable public web behavior, including HTTP, DNS, TLS, response timing, Lighthouse results, page structure, metadata, accessibility signals, and machine-readable interfaces. It provides a live shared report for the result.
No. NotiDuck does not measure model rankings, answers, mentions, or citations, and it does not guarantee recommendations, rankings, indexing, or citations. It measures technical and page signals that can affect access to a site.
NotiDuck is a good fit for teams or individuals deploying websites frequently, developers using coding agents, operators managing multiple sites, and people who want uptime, performance, SEO, and machine-readability checks in one workflow.
Start with a live website check across uptime, performance, SEO, and machine-readable public web signals.
