What to measure
Start with the prompt and answer. Record brand mentions, recommendation order, descriptions, cited URLs, provider, account or location context, and run time. Keep the raw answer so a reader can audit the metric. Define what counts as a mention before scoring, including aliases and names shared by several brands.
Separate answer mentions from citations. A brand can appear without its own site being cited; a source can be cited without an explicit brand recommendation.
Build a useful prompt set
Include category, problem, comparison, and purchase-intent prompts that real buyers might ask. Write the list before running the study. Keep prompts stable across repeated runs and record any change.
Group results by topic and product. Report attempted runs, valid captures, and failures beside each rate. Apply the same rule across dates; a changing denominator can distort a trend.
Don’t overread small changes
Change the wording, account, location, or date and you may get a different answer. Show how many runs you made and how you got the answers. Repeat prompts before calling a small change a trend.
