Credits, answers, and prompts are different workloads
Rankscale publishes credits and estimated answer counts: Pro has 1,200 credits and up to 4,800 answers, while Growth has 5,500 credits and up to 22,000 answers. Digraph publishes 30 or 300 tracked prompts and brand limits. Because engine costs vary, model the exact prompts, engines, schedules, regions, and stored answers your team needs before treating the monthly quotas as equivalent.
Compare breadth with traceable evidence
Rankscale emphasizes many engines, visibility trends, competitor benchmarks, citation share, query fan-out, and source-box analysis. Digraph emphasizes the prompt, full answer, recommendation context, cited URL, source domain, competitor framing, and follow-up analysis behind a finding. Use the same citation-gap example and record whether each product exposes the evidence needed to choose and verify an action.
Test cadence and credit consumption with real prompts
Rankscale lists hourly, daily, weekly, monthly, and optional bi-cadence schedules, with each engine query consuming a fraction of a credit. Digraph uses tracked prompts and selected AI systems as the planning unit. Run the same prompt set at the same cadence for a defined window and record credit consumption, model modes, answer retention, and result stability.
Evaluate page audits and client delivery separately
Rankscale bundles URL page audits, shareable dashboards, exports, Looker Studio, and higher-tier white-label or API access. Digraph lists reports and exports on public plans and Enterprise API access, with evidence connected to audit and analysis workflows. Test technical audit depth, permissions, client separation, branded delivery, export fields, archive retention, and the effort to turn a citation gap into a verified change.
Run a controlled side-by-side pilot
Use the same brand, competitors, categories, markets, language, buyer questions, active engines, collection window, and reporting format. Record full answers, prompt and engine context, brand position, competitor mentions, sentiment, citations, cited URLs, source domains, page-audit findings, proposed actions, refresh time, and credits or prompts consumed. Compare one recurring report and one verified follow-up action before choosing the operating model.
