Tests & working tools
When evaluating a recommendation, I want to understand its evidence and how to test it. This collection brings together tests, examples and tools from my site. Each serves a different purpose: an experiment on this website, a worked decision or a worksheet for your own observations.
Documented test on this website
A task test on Nirlevi.com covering form completion, error recovery and file download. The article provides conditions, evidence and limitations. The described checks used Codex assistance; this is not a client result.

Read the guide and evidence ↗Tool for your own observations
Build a question set and retain answers, sources and repeated observations. The worksheet separates mentions, citations and recommendations. It is a working template, not a pre-collected research dataset.
Read the guide and evidence ↗These are resources published on my own website. They are not independent endorsements or client project results. Each guide records its methods, sources and writing assistance.
Establish what was tested, on which site or market and under which conditions. A screenshot alone is not enough to support a conclusion.
Check who ran the test, when, with which tool and how many repeats. In AI answers, distinguish a mention, a source citation and a recommendation.
A result from one task can suggest something to investigate on your site. It does not establish that the same change will produce the same result elsewhere.
