## How to choose

- Data freshness per figure: Check whether every ranking, volume and traffic figure comes with the date it was measured, since an agent that mixes stale and current numbers will give a wrong answer.
- Data sets behind each call: Check which data sets sit behind each call, such as search volumes, backlinks, referring domains and rankings, since a listing may cover only some of them.
- Cost per call and run: Check how each call is charged, by credit, request or allowance, and what a full domain run costs, so an agent's budget is set in advance.
- Keyword and domain limits: Check the maximum number of keywords and domains per request and the rate limit, since a batch of keywords for many domains may need splitting across calls.

- How the benchmark tests this category: The same ten domains and fifty keywords asked of each listing (search volume, ranking position, backlink count, referring domains and a traffic estimate). We check coverage, the date of each figure, agreement between listings and the cost of the run. In this run listings are graded from public evidence against the published checklist.
