What counts against my plan: queries, products, engines?

What counts against your plan is the number of queries tracked per month, not the number of products or engines. Each plan includes a monthly query quota (50 on Starter, 150 on Growth, 300 on Pro, unlimited on Enterprise) plus access to a fixed set of engines: ChatGPT on Starter, then Perplexity, Gemini and Google AI Overviews on Growth, then Google AI Mode on Pro. Your products are covered separately, up to 5,000 SKUs, at no extra cost.
