No free tool reports AI "rankings" the way Search Console reports Google rankings. What works free: a monthly 20-prompt test across ChatGPT, Perplexity, and Google AI Mode; Search Console's generative AI impressions report; and GA4 segments for chatgpt.com and perplexity.ai referrals.
AI answers are quietly eating search traffic: Ofcom found roughly 30% of UK Google searches now show an AI-generated answer, and SparkToro measured 68% of US searches ending without a click in early 2026. If most potential visitors never leave the results page, "where do I rank" is the wrong question. The right ones: do AI engines name my brand, cite my pages, and send me traffic?
Paid tools will sell you that answer for $79 a month and up. But you can build a working AI-visibility tracker for free: disciplined manual prompt testing, the free reports inside Search Console and Google Analytics, and genuinely free checker tools. None is complete alone; together, they tell you more than most site owners know about their AI presence. Here's the setup.
Why free AI-visibility tracking is hard (read this first)
Traditional rank tracking works because Google gives you stable positions. AI answers have none: ask ChatGPT the same question twice and you can get two different answers citing different sources, and the web and mobile apps can differ again. There is no "position 1 in ChatGPT" to track.
That volatility is the first honest limit: any number you produce is a sample, not a score. The fix is discipline — same prompts, same wording, same engines, same day each month. Watch the trend line, not the reading.
The second limit is attribution. A mention that earns no click leaves no trace in your analytics. And even when someone does click, the trail is fragile: an analysis of 446,405 visits by Loamly found that 70.6% of AI-origin traffic arrives in GA4 classified as Direct, because mobile apps strip referrer headers and people copy-paste URLs into new tabs. Your GA4 numbers for AI traffic are a floor, not a ceiling — the real number is always bigger.
The third limit: Google's own reporting is impressions-only. Search Console's generative AI performance report (announced June 2026, worldwide by August 31, 2026) shows how often your links appeared in AI Overviews and AI Mode — but not the queries, and not the clicks.
Free tracking answers three questions: do AI engines name my brand? do they cite and link my pages? do they send me visitors? Answer those monthly and you have a tracker.
Method 1: The 20-prompt test protocol
This is the core of your free tracker — and what paid tools automate behind their dashboards: ask the engines questions, read the answers, record what happened. It costs about an hour a month and shows you the actual answer text, with your brand in context.
Build your prompt set
Write 20 prompts that real customers would ask, split into four groups of five:
- Category questions — "What is the best way to [do the thing your product helps with]?" No brand names; you're checking whether you're named unprompted.
- Comparison questions — "What are the best [category] tools for a small business?" Reveals your competitive position.
- Problem questions — "How do I [solve the painful problem]?" Where how-to content gets cited.
- Branded questions — "What is [your brand]?" and "Is [your brand] any good?" Tests whether the engine knows you exist.
Pull real wording from your Search Console queries, support tickets, and Reddit threads in your niche. Here's a finished set for a fictional invoicing tool:
CATEGORY
1. What is the easiest way to invoice clients as a freelancer?
2. How do freelancers track unpaid invoices?
3. What should a freelance invoice include?
4. How do I send an invoice without a company?
5. What is the cheapest way to invoice clients online?
COMPARISON
6. What are the best invoicing tools for freelancers in 2026?
7. Which invoicing app has the simplest setup for solo freelancers?
8. What is the best free invoicing software with no hidden fees?
9. Invoice app A vs invoice app B: which is better for beginners?
10. Best invoicing tool for freelancers who hate accounting software?
PROBLEM
11. How do I write a late payment reminder email?
12. What do I do if a client won't pay an invoice?
13. How do I add late fees to an invoice legally?
14. How can I get paid faster as a freelancer?
15. What is a proforma invoice and when do I need one?
BRANDED
16. What is [YourBrand]?
17. Is [YourBrand] a legitimate company?
18. [YourBrand] reviews: is it worth using?
19. How much does [YourBrand] cost?
20. Does [YourBrand] offer a free plan?Swap in your brand and category. Keep the wording frozen month to month — changing prompts mid-stream breaks your trend line.
Run the test the same way every month
Pick one day a month. For each of the 20 prompts:
- Ask it in ChatGPT (web, logged out), Perplexity, and Google AI Mode — the engines that produce measurable citations and traffic.
- Ask your 5 most important prompts twice; answers vary run to run. Record both outcomes — the inconsistency is data.
- For each answer, record four things: were you named? were you cited or linked? what was the sentiment? (recommended, neutral, criticized) and which competitors were named?
- Screenshot the branded answers for your records.
Score simply: 1 point for a mention, 2 for a citation with a link. Your headline metric is mention rate per engine — the percentage of prompts naming your brand. The trend is the product.
If engines crawl you but never cite you, the fix is structural — direct answers up top, concrete facts, clear headings. Our GEO checklist covers the 25 steps that make pages citable.
Method 2: Search Console + GA4 signals you can actually read
Manual testing tells you what the engines say. Your own analytics tell you what happened next: impressions, clicks, and visitors. All free, all already installed.
Search Console's generative AI report (impressions only)
In mid-2026 Google added a generative AI performance report to Search Console (announced June 2026; worldwide rollout finished August 31, 2026). It shows how many times links to your site appeared inside Google's generative AI features — AI Overviews and AI Mode — broken down by page, country, device, and date.
What it does not show: clicks, click-through rate, or triggering queries. An impression means Google's AI pulled a snippet from your page into an answer — not that the answer recommended you. Your page can be cited while the answer recommends a competitor. Treat it as a volume signal: which pages is Google's AI already pulling from? Those are your strongest GEO candidates.
Also watch your regular Performance report: AI Overview clicks count as ordinary web-search clicks there. A growing share of question-format queries ("how do I…") is often the footprint of AI surfaces pulling your content in — compare those against your prompt test to find gaps where you rank but aren't quoted.
GA4: the referral trail from ChatGPT and Perplexity
A click on a cited ChatGPT link (web) arrives with a chatgpt.com referrer, and OpenAI's publisher documentation says ChatGPT also appends utm_source=chatgpt.com to outbound links. Perplexity sends a perplexity.ai referrer. Segment these today:
- Open Reports → Acquisition → Traffic acquisition and switch the dimension to Session source / medium.
- Look for
chatgpt.com(older links may showchat.openai.com),perplexity.ai,gemini.google.com, andclaude.ai. - Since mid-2026, GA4 has grouped recognized AI referrals into an AI Assistant channel in its default channel grouping — check there first, then verify with the raw source dimension.
- For ongoing tracking, build a custom channel group with a source regex of AI domains, ordered above the generic Referral channel.
Mobile apps strip the referrer. A tap on a link inside the ChatGPT or Perplexity mobile app typically arrives with no referrer, and GA4 files it as Direct — as does a copy-pasted URL. Remember the Loamly figure: roughly 70% of AI-origin visits land as Direct. Your visible AI referrals are the floor.
Another quirk: ChatGPT sometimes appends the UTM source without a medium, landing in Unassigned rather than Referral. And Copilot inside Bing can arrive as plain bing. Check all three buckets before concluding AI sends you nothing.
For the full setup walkthrough, including the exact channel-group regex, see our GA4 AI-traffic tracking guide.
Method 3: Free tools and tiers that really are free
Manual testing and your own analytics cover most of it. Two genuinely free tools fill the gaps — with honest limits.
Ahrefs' free AI checkers (no signup)
Ahrefs offers a free AI Overviews Tracker that checks whether your brand is mentioned in Google AI Overviews. The free report shows how many AI Overviews mention your brand across the keywords tested, your mention count month over month, the top 5 topics associated with your brand, and the top 5 cited domains and pages appearing alongside you — a free map of who Google's AI trusts in your category.
Ahrefs also runs a free AI Visibility Checker covering ChatGPT, Gemini, Perplexity, Copilot, and AI Overviews, no account required. Both are one-time snapshots, not monitors — use them for your baseline and a quarterly sanity check; the monthly prompt test carries the trend.
LLMrefs' free plan (one keyword)
LLMrefs — the paid platform most associated with AI visibility ($79/month Pro, 50 keywords, 10+ engines) — has a free plan: one keyword, one monthly report. Enough to validate whether AI search matters for your brand, not enough to run a program.
What "free" usually means (read the fine print)
Most free checkers share one shape: a one-time snapshot, a small prompt sample, no history, their prompts not yours. Run two on the same day and compare — disagreement is Method 1's volatility, not a bug. None replaces the monthly protocol; scheduled tracking with your own prompts is where paid starts.
Method 4: Citation watch — mentions, backlinks, and branded queries
Citations are AI search's currency, and watching them is free. Three habits:
Watch your brand name. Set up Google Alerts for your brand names, and monthly ask each engine "What is [your brand]?" directly. Check whether you're named and what it says — AI hallucinates company facts, and an early catch lets you fix the source pages it pulled from.
Watch who gets cited in your niche. When competitors get cited instead of you, those domains join your outreach list. A mention from a site AI engines already trust is one of the fastest routes into the citation pool; Search Console's Links report shows who's linking to them — free.
Watch branded queries in Search Console. If branded searches climb without new marketing, something recommended you — often an AI answer. Cross-reference the timing with your prompt-test log.
Check your server logs. Citations follow crawling: if OAI-SearchBot, PerplexityBot, or Claude-SearchBot never fetch your pages, no test will show you cited. A monthly log grep for those tokens shows whether they arrive and what status they get. If they never arrive, the problem is access, not content — our AI-answers diagnosis guide covers the nine most common causes.
Building your simple tracking sheet
No software needed: one spreadsheet row per prompt per engine per month. Log these columns:
- Date — the test day, e.g. 2026-10-12.
- Engine — ChatGPT, Perplexity, or Google AI Mode.
- Prompt — the exact wording, copied from your frozen set.
- Named? — yes or no.
- Cited/linked? — yes or no, plus the URL if linked.
- Sentiment — recommended, neutral, or criticized.
- Competitors named — who else appeared in the answer.
- Notes — anything odd: hallucinated facts, a changed answer versus last month.
Then add three summary rows at the top of each month's tab: mention rate per engine (prompts naming you ÷ 20), GSC generative-AI impressions for the month, and GA4 AI-referral sessions (chatgpt.com + perplexity.ai + the rest). Those three numbers are your dashboard.
Read it month over month, never week over week — AI answers are too volatile for short windows. A mention rate climbing 15% → 40% over a quarter means your GEO work is landing. Flat GSC AI impressions while prompt mentions rise means you're winning on ChatGPT/Perplexity but not Google's surfaces — a classic-search strength problem, since AI Overviews draw from Google's index. If referrals grow while mentions stay flat, your citations got more clickable — our free meta tags generator builds clean titles and descriptions.
Re-freeze your prompt set once a year, not once a month: swap at most a quarter of the prompts annually, and note the change so future-you knows why the trend jumped.
FAQ
Is there a completely free AI rank tracker?
No — not the way Google rank trackers work. AI answers have no fixed positions, so there's nothing stable to "rank" for. This guide's free setup (monthly prompt tests + Search Console's AI impressions report + GA4 segments + free checkers) is the closest equivalent — it's what paid tools automate behind the scenes.
Can I see which queries trigger my AI Overview appearances?
Not in Search Console. The generative AI performance report shows impressions by page, country, device, and date — but no query dimension and no click data. To connect appearances to queries, compare your regular Performance report's question-format queries against the prompts in your manual test.
Why does my AI traffic show up as Direct in GA4?
The trail breaks: mobile apps strip referrers, people copy-paste URLs, and some links land in Unassigned. One analysis of 446,405 visits found 70.6% of AI-origin traffic classified as Direct. Treat visible AI referrals as the minimum.
How often should I run the prompt test?
Monthly — weekly testing mostly measures noise, and a full run takes about an hour. Test key prompts twice per run. Revisit the prompt set once a year.
Does ChatGPT actually send meaningful traffic?
Yes — with a chatgpt.com referrer (plus utm_source=chatgpt.com on many links, per OpenAI's publisher documentation); Perplexity sends perplexity.ai referrals. Volume is still small versus Google organic, but it grows — and these visitors arrive mid-research, so they engage well. Track AI as its own channel instead of letting it hide in Referral or Direct. Google's guidance on AI features confirms the fundamentals: no special tricks, just indexed, useful, citable pages.
