Comparisons: frequently asked questions
How did you compare these tools?
We read each vendor's public pricing and product pages on October 24, 2026 and list what they say, with links to the sources. "Not listed" means the page doesn't mention a feature — it may still exist. Peec AI doesn't publish prices, so its figures are third-party reports and marked as such.
Which AI visibility tool is the cheapest?
It depends on how many prompts you track, on which engines, how often, and whether you also need Google rank tracking. The AI tracking cost calculator prices the same usage on every tool so you can compare like for like.
Does serp.ac check AI answers every day?
Not today: serp.ac re-checks AI prompts weekly (every 2 weeks on starter). Google rankings are checked daily on every plan. Several tools on this page check AI answers daily — if daily AI data is essential, they may suit you better.
Which of these tools manage purchased links?
None of the compared tools offers purchased-link management with prices, payment dates, renewals, vendors and deindex alerts, or a built-in Google indexer. Those are core serp.ac modules.
