Is the scan really free?

Yes. One scan per domain per day with no credit card required. You get an AIS score, per-engine breakdown, up to 3 citation gaps, and 5 quick-win recommendations. Paid plans unlock daily scans, historical tracking, and Slack alerts.

How does AISearchStackHub scan AI engines without API access?

We use structured query templates optimized for each engine's response patterns — testing brand mentions across 24 variants per domain including industry terms, product categories, and comparison queries. We measure citation frequency, context quality, and entity prominence.

What does my AIS score mean?

0–39: AI-invisible. Your brand is rarely or never cited by AI engines. 40–69: Emerging visibility with gaps to close. 70–89: Strong AI presence in your category. 90–100: Top-tier citation authority. We show per-engine scores so you know where to focus.

How accurate is the citation gap analysis?

We show the top 3 gaps in the scan — these are the highest-impact missing citations based on competitor benchmarking. The $49 Citation Gap Report delivers a full audit of every source AI engines cite for your brand, including competitor comparison and prioritized fix roadmap.

How long does a scan take?

Typically 30–90 seconds. You'll see a loading state while we query multiple AI engine patterns, then your results appear with the overall score, per-engine cards, citation gaps, and your Citation Health badge.

How does the AI Visibility Scanner work?

The scanner runs your domain against 24 real query variants across ChatGPT, Claude, Perplexity, and Gemini — the four major AI engines. It checks whether your brand is mentioned, cited, or recommended in answers to category-relevant questions, then returns a 0–100 AIS score with per-engine breakdowns, citation gaps, and prioritized quick wins.

How long does a scan take?

Most scans complete in 60 seconds or less. The scanner queries all four AI engines in parallel across 24 query variants, so the total time is roughly the slowest single engine response, not the sum of all requests.

What does my AIS score mean?

The AIS (AI Search) score is a 0–100 composite of how often and prominently your brand appears across ChatGPT, Claude, Perplexity, and Gemini. Below 30: your brand is largely invisible to AI engines. 30–60: partial visibility with significant gaps. 60–80: solid presence with room to compound. Above 80: strong AI citation presence — focus on maintaining and expanding.

What are citation gaps?

Citation gaps are queries where your brand does not appear in AI answers even though relevant sources are cited. For example, if ChatGPT recommends three tools for 'B2B lead generation software' and yours isn't among them, that's a citation gap. The scan surfaces your top 3 gaps with specific recommendations for how to close them.

Do I need to create an account to scan?

No account required. Enter your domain, get your score. You'll be offered the option to receive your full report by email, which also unlocks the citation gap details and quick wins.
