What does it cost to track whether ChatGPT and Google's AI answers mention your brand?
Summary
Tracking a few dozen prompts usually fits inside an SEO plan's allowance or adds $50 to $100 a month. The bill depends less on how many prompts you pick than on how many AI platforms you check them on and how often. Ahrefs, which prices this openly, counts one check per prompt, per platform, per location, per refresh.
Working through one example
Say you want 30 prompts checked daily on four platforms. At Ahrefs that's 30 × 4 × 30 days, or 3,600 checks a month. Lite ($129) includes 150, which leaves 3,450. The $50 Basic package adds 2,500 checks, and the remaining 950 are billed as overage at $0.020 each, or $19. So the tracking costs about $69 a month on top of Lite, a little less than the $100 Growth package with 7,000 checks.
Switching the same prompts to weekly refreshes cuts the count to roughly a seventh. Ahrefs' help center says tracked prompts can refresh monthly, weekly or daily, and that a lower frequency lets you track more prompts. Its Brand Radar page adds that Claude uses eight checks per update. New responses can take up to 24 hours to show up.
How other vendors count
| Vendor | Price | Prompts | Note |
|---|---|---|---|
| Semrush AI Visibility Toolkit | $99 per domain per month, billed annually | 25 tracked daily; 50 more for $60 a month | The pages don't say whether one prompt on several engines counts once or several times |
| SE Ranking Core / Growth | $129 / $279 a month ($103.20 / $223.20 annual) | 100 / 250 daily, five LLMs | AI Search add-on: $89 a month for 200 prompts ($71.20 annual) |

Semrush covers ChatGPT, Google AI, Gemini and Perplexity, and its setup asks you to pick one search engine per campaign. It supports desktop searches only.
A vendor's own index size isn't settled either
Several vendors also sell access to answers they've collected across a large pool of prompts. Ahrefs' Brand Radar starts at $199 a month and is re-tested monthly on a 90-day reporting window. The size of that pool depends on which Ahrefs page you read: 449 million prompts in the Brand Radar page body, 475 million in its meta description and on the pricing page, and 350 million in the help article.
