Keyword.com (formerly Serpbook) is a rank tracking platform founded in 2014. Keyword.com has been in the search tracking space for over a decade and has added an AI Visibility module that tracks brand mentions across 7 LLMs. Keyword.com brings its experience in traditional search ranking to the AI visibility space, offering the AI module as an add-on to its existing rank tracking platform or as a standalone purchase.
If you're evaluating AI visibility tools, here's a detailed breakdown of how Keyword.com works, what Keyword.com costs, and how Keyword.com compares to Mentionable.
How does Keyword.com track AI visibility?
Keyword.com's AI Visibility module monitors brand mentions across 7 platforms: ChatGPT, Perplexity, Google AI Overviews, Gemini, Claude, DeepSeek, and Mistral. Users set up prompts (keywords or queries), and Keyword.com checks whether the brand appears in AI-generated responses across selected engines.
Keyword.com's citation tracking identifies which pages and sites get cited in AI answers. This helps users understand what content is driving their AI visibility. Keyword.com's competitive analysis compares visibility and citations against competitors, showing where competitors are winning and where gaps exist.
Keyword.com includes brand sentiment analysis that monitors whether mentions are positive, negative, or neutral. Keyword.com's Google AI Overviews tracking shows when AIO appears for keywords and which URLs are cited.
Keyword.com uses a credit-based system where each refresh consumes credits per engine. Users can schedule manual, hourly, daily, or weekly updates. Tracking across all 7 LLMs consumes credits faster than tracking a single engine.
Notably, Keyword.com does not track Google AI Mode.
How much does Keyword.com cost in 2026?
Keyword.com AI Visibility starts at $24.50/month for 50 credits. The AI module can be purchased as an add-on to existing Keyword.com plans or as a separate purchase. A 14-day free trial is available.
Credits reset monthly and don't roll over. Each engine consumes credits separately, so tracking across all 7 LLMs depletes the allocation faster than tracking a single engine. The effective monthly cost depends heavily on how many engines are tracked and how often refreshes are scheduled.
| Aspect | Keyword.com | Mentionable |
|---|---|---|
| Starting price | $24.50/month (50 credits) | €79/month (Growth, 40 prompts) |
| Pricing model | Credit-based (per engine, per refresh) | Flat monthly on Growth and Pro, €299/month on Agency |
| LLMs covered | 7 | Up to 7 (user picks 3-4 depending on plan) |
| Cost predictability | Variable (depends on usage) | Fixed on Growth and Pro |
| Free trial | 14 days | 4 days, no credit card |
Light users who track a few prompts on one or two engines may find Keyword.com's credit system affordable. Heavy users tracking across all 7 LLMs with frequent refreshes could burn through credits quickly.
What does Keyword.com do well?
Keyword.com's $24.50/month entry price is one of the lowest starting points for AI visibility tracking. For brands testing whether AI visibility monitoring is worth the investment, Keyword.com removes the cost barrier.
Keyword.com's 14-day free trial lets users test the platform before committing money. Most enterprise AI visibility tools either don't offer trials or require a sales process to get started.
Keyword.com has been in the search tracking space since 2014. Keyword.com's longevity and rank tracking expertise give it credibility, and its infrastructure is mature. Keyword.com is not going anywhere.
Keyword.com's 7-LLM coverage is solid. ChatGPT, Perplexity, Gemini, Claude, DeepSeek, Mistral, and AI Overviews cover a wide range of the AI search landscape. For users already tracking Google rankings with Keyword.com, having AI visibility in the same dashboard is a practical advantage.
