Buy monitoring around the questions you can maintain
Inspect prompt coverage, engine selection, location settings and the evidence behind each observation. Ask to export an answer with its date and cited sources. A dashboard is easier to evaluate when your team can trace one trend back to the underlying answers.
Price the work after a gap is found
List the people required to correct a single outdated claim: someone to approve the fact, someone to change the page and someone to verify the result. If those roles are already staffed, the software can support their existing workflow. A managed scope puts named owners and deliverables around the same work.
Make competing proposals answer the same question
Give each provider one representative URL and buyer question. Ask what evidence you would receive, what can be published within the period and what remains with your team. Compare the full operating cost, including internal time spent on approvals and implementation.
