Does AI Search Sensor show my brand’s visibility?

No, AI Search Sensor won’t show your brand’s visibility, but HubSpot AEO can. AI Search Sensor estimates visibility patterns across tracked industries. To analyze visibility for a specific brand, marketers can set up tracking with HubSpot AEO, plus get recommendations for immediately improving their visibility .

What is answer engine optimization (AEO)?

Answer engine optimization (AEO) is the practice of improving how a brand appears in responses generated by answer engines. Instead of ranking webpages in search results, answer engines generate direct responses using information from multiple sources.

How often is AI Search Sensor data updated?

The AI Search Sensor runs on a daily refresh cadence. A "Last Updated" timestamp on each chart indicates the most recent data pull. Refresh timing may differ per chart depending on answer engine volatility and upstream processing delays.

What’s the difference between AI Search Sensor, AEO Grader, and HubSpot AEO?

Each product helps you understand AI visibility at a different level: AI Search Sensor (free) gives you a high-level view of the AEO landscape, tracking shifts in citation and mention frequency, trends in AI-referred traffic, and estimated benchmarks by industry to show how AI answers are changing over time. It’s designed to help you spot patterns in the landscape, not measure a specific business. AEO Grader (free) gives you a scored snapshot of how ChatGPT, Perplexity, and Gemini represent your brand today – covering sentiment, share of voice, brand recognition, and competitive positioning. It shows you how answer engines represent your brand and where your presence may need strengthening. HubSpot AEO ($50/month) is an AEO tool that allows you to track how your brand shows up across answer engines, analyze competitors, and get prioritized, plain-language recommendations to increase your visibility. AEO (included in Marketing Hub Pro and Enterprise) uses customer data to give you smarter recommendations from day one, tracks how your brand shows up across answer engines, compares you to competitors, and turns those insights into a prioritized list of actions you can take immediately using HubSpot’s marketing and content tools — all in one system.

AI Search Sensor BETA

Your free dashboard for AI answer data & trends.

AI Search Sensor is a free dashboard that tracks how answer engines like ChatGPT, Gemini, and Perplexity cite brands, surface content, and send traffic — so you can benchmark your AEO performance and adapt your strategy.

Today's signal: Moderate

Some movement. Noticeable shifts in how answer engines cite and surface businesses. Check the Answer Engine Volatility Tracker below for details.

AI-Referred Traffic Trends

See how much traffic answer engines are sending to websites.

Last updated July 11.

AI-referred traffic is based on anonymized HubSpot customer data and modeled to show aggregated page visit trends from ChatGPT, Gemini, and Perplexity each week. Actual results may differ by region and language. Weekly data runs Monday-Sunday; it can take a few hours for all traffic data to populate.

A traffic dip isn't always your fault. This chart helps you find out.

The numbers here show what's happening across the industry, not for your brand specifically. The way to get the most out of this chart is to compare it to your own traffic data — once you know what the industry is doing, you can figure out what it means for you:

Industry traffic is up, but you're flat or declining: You may be losing traffic share compared to your competitors. That's a signal to audit your AEO coverage, specifically looking at which engines are sending traffic, and whether your content is showing up in their answers. A good next step is to check the Citation Share Trends chart to see which content types are earning the most citations right now. Compare that against what you're actually publishing.
Industry traffic is down, and so are you: Likely a market-wide shift rather than a strategy problem. Check the Answer Engine Volatility Tracker to see if conditions changed that week. If they did, that context is probably your answer.
Industry traffic is down, but you're holding steady or growing: Your strategy is outperforming the market average. Take note of what you've been doing differently, because it's working.

Review each answer engine to see whether one is driving the traffic trend more than the others. Sometimes the picture looks very different depending on which platform you're looking at.

AI traffic is up for grabs.

AI Visibility Benchmarks by Industry

See how often brands in your industry are appearing in AI search results, and whether that’s changing over time. Get insights into a company’s and across multiple weeks.

Last updated July 11.

Benchmarks reflect estimated trends from representative brands within each industry. Weekly data runs Monday-Sunday for ChatGPT, Gemini, and Perplexity data; each week appears once complete. Visibility score and citation share each utilize a 0-100% range, with graphs autoscaling for easier readability.

Use the brands you recognize to calibrate what's realistic in your industry.

The companies shown aren't necessarily competitors — they're familiar names chosen to give you a meaningful benchmark. When you select your industry, you're not watching a race. You're getting a baseline for what typical AI visibility looks like and how wide is the spread between brands.

In some industries, the top performers sit well above 70% visibility while others cluster around 30%. In others, the field is much tighter. Once you know the range, use it as a comparison point for your own brand. Pick a company in your industry that you'd consider a household name and note where they're sitting. If your own visibility score is tracking close to theirs, you're in the conversation. If you're well below them, you have a clear sense of how much ground there is to make up. And, if you're above them, that's a meaningful signal that your AEO strategy is working.

Toggle between Visibility Score and Citation Share to see both sides of the picture. A brand can be frequently named in AI answers without being cited as a source, meaning they have a strong, reputable presence across the web but a weaker content strategy. Inversely, if a brand is cited heavily without being named, they have a significant catalog of well structured content, but they need to improve their authority — or why someone should choose to buy their products & services.

Answer Engine

Watch for what's shifting, not just what's dominant.

Content Type:

This view shows which formats of content — blogs, comparison pages, documentation, guides, and others — are being cited most in AI-generated answers each week.

The content types holding the largest share tell you what AI engines are currently treating as authoritative. But another actionable signal is movement. A content type steadily growing its share week over week is one the engines have started favoring more recently — and a format potentially worth investing in if you're not already publishing it regularly. Equally, a content type that's shrinking is one losing favor, which may mean deprioritizing it isn't as risky as it once seemed.

When you see a significant shift, cross-reference it with the Volatility Tracker. A sudden change in the mix during an Elevated or Extreme week usually means the engine updated how it weights certain content. That shift is likely affecting everyone, not just you.

Channel:

This view shows which types of sources AI engines are pulling citations from — owned content (your website), earned media, review sites, affiliates, UGC, and others.

The most important thing this chart communicates is that AEO isn't just about what's on your website. AI engines pull from the entire web when deciding what to cite. In many cases, third-party sources like review sites, affiliates, and others carry significant weight in what gets surfaced.

If you look at this chart and see review sites or affiliates holding a large or growing share vs. owned, that's a signal that AI engines in your space are trusting what others say about brands more than what brands say about themselves. If your current strategy is focused entirely on your own content, this chart is telling you there's a meaningful piece of the picture you're not influencing.

On the flip side, if owned content is consistently strong in your industry, that's validation that investing in your own site — your blog, your product pages, your documentation — is the right place to focus.

Use this view to pressure-test where your effort is going. If the channels gaining share are ones you're not active in, that's the gap worth closing first.

Affiliate: Affiliate sites, where you can pay to have your content published
Competitor: Competitor domains, from the competitors set up during onboarding
Earned: Earned media, including news or PR
Owned: Your own domain
Peer: Peer sites are product/service companies that are not your direct competitors
Review sites: Third-party platforms where users rate and review products, such as G2, Capterra, and Trustpilot.
UGC: User Generated Content sites such as Youtube / Reddit

See who’s winning citations — and take more share.

Spot where you're gaining ground, losing it, and where to win it back.

*Daily volatility based on mention rate, citation rate, citation type, and AI-referred traffic compared to rolling averages from ChatGPT, Gemini, and Perplexity.

This data represents directional trends of how brand visibility changes within AI responses. Daily volatility scores may fluctuate slightly for three days from the current day.

Your weather report for AI engines.

When something looks off in your own AEO metrics, check here for what the market is experiencing. A spike in volatility means the engines have changed. How many links they show, how often they name brands, what sites or content they reference most, and how much traffic they send can all be shifting.

Use the score alongside your own data to diagnose what's actually happening:

Score is Elevated or Extreme, and your metrics dropped: Likely a market-wide shift. Focus on understanding what changed before making any adjustments to your strategy — reacting too quickly to engine-level changes often creates more disruption than the change itself.
Score is Calm, but your metrics dropped: This is worth investigating. The market is stable, which means the shift is more likely specific to your brand or content. That's the moment to look at your citation share and visibility data more closely.
Score is Elevated or Extreme, but your metrics are holding: Your content is weathering the shift better than average. Take note of what you've been doing, because it's working.

Don't just watch the trends, track your own.

Frequently Asked Questions

AI Search Sensor is a free public dashboard that shows how answer engine behavior is shifting in real time. It monitors daily answer engine volatility, weekly AI-referred traffic, and weekly visibility and citation data per industry from ChatGPT, Gemini, and Perplexity.

Answer engines constantly change who they cite, what content they surface, and how often brands appear. AI Search Sensor shows if the shifts are widespread across the industry. Marketers can use this data to better understand AEO trends.

AI-Referred Traffic Trends

Methodology: The AI-Referred Traffic Trends chart showcases the aggregate of ChatGPT-, Gemini-, and Perplexity-referred traffic to HubSpot customers by week. The data set is comprised of anonymized HubSpot customer data.

Context: This chart allows marketers to compare their own traffic performance to the wider industry. For example, when a marketer sees a traffic dip, their reflex is to audit their strategy. But, traffic declines aren’t always within marketers’ control – sometimes they’re a factor of an answer engine model change or AI usage behaviors shifting.

AI Visibility Benchmarks by Industry

Methodology: The AI Visibility Benchmarks by Industry chart shows visibility and citation share of four representative companies within ten industries from ChatGPT, Gemini, and Perplexity. The data that powers these calculations are estimates based on publicly available information – like a company’s top products, competitors, and assumed customer profiles.

Context: AI visibility and citation share for companies will vary by industry. This snapshot provides a benchmark for how companies typically perform within an industry.

Citation Share Trends

Methodology: The Citation Share Trends chart calculates what citations (or links) in AI answers look like and how they change on a weekly basis. Anonymized HubSpot customer data based on responses from ChatGPT, Gemini, and Perplexity power this chart. This chart tracks citations by Content Type, or the type of URL answer engines link to. Sixteen Content Types are monitored including: product pages, listicles, blog posts, PR, and more. This chart also tracks Channel, or which kind of websites answer engines link to. Nine channels are monitored including: affiliate, peer, earned, review sites, and more.

Context: The Content Type portion of this chart helps users understand if the content they’re publishing or have live on their site is relevant to AEO. For example, answer engines often cite product pages, listicles, blog posts, and guides. You should evaluate if these content types align with the content your company is actually producing. The Channel portion of this chart helps users understand if their marketing strategy is optimized for AI Search. If your goal is to grow your AI visibility, this chart outlines how you need to be focusing on off-site efforts like affiliate mentions, earned media, partnerships, and reviews on review sites, not just optimizations to your own website.

Answer Engine Volatility Tracker

Methodology: The Answer Engine Volatility Tracker chart calculates daily volatility in answer engine results based on mention rate, citation rate, citation type, and AI-referred traffic vs. rolling averages. The data set is comprised of anonymized HubSpot customer data and evaluates ChatGPT, Gemini, and Perplexity. Daily volatility scores may fluctuate slightly for three days from the current day as final data rolls in.

Context: Model changes and behind the scenes updates from ChatGPT, Gemini, and Perplexity will alter the contents of AI results. For example, with one model you may see a lot of links to businesses (also known as citations), but once a new model update rolls out, you may see only one or two links. Changes like this within answer engine results is what the Answer Engine Volatility Tracker monitors.

Each product helps you understand AI visibility at a different level:

AI Search Sensor (free) gives you a high-level view of the AEO landscape, tracking shifts in citation and mention frequency, trends in AI-referred traffic, and estimated benchmarks by industry to show how AI answers are changing over time. It’s designed to help you spot patterns in the landscape, not measure a specific business.
AEO Grader (free) gives you a scored snapshot of how ChatGPT, Perplexity, and Gemini represent your brand today – covering sentiment, share of voice, brand recognition, and competitive positioning. It shows you how answer engines represent your brand and where your presence may need strengthening.
HubSpot AEO ($50/month) is an AEO tool that allows you to track how your brand shows up across answer engines, analyze competitors, and get prioritized, plain-language recommendations to increase your visibility.
AEO (included in Marketing Hub Pro and Enterprise) uses customer data to give you smarter recommendations from day one, tracks how your brand shows up across answer engines, compares you to competitors, and turns those insights into a prioritized list of actions you can take immediately using HubSpot’s marketing and content tools — all in one system.

Be found where search happens.

Discovery is happening in answer engines — is your brand the answer? Use HubSpot AEO to see how your brand shows up, where competitors are winning, and how to maximize your visibility.

ChatGPT Update

We've upgraded memory so ChatGPT can better keep your context up to date, helping responses stay more relevant. This makes memory more useful by reducing stale or contradictory saved memories and helps ChatGPT better understand your preferences, goals, and ongoing work. You can review the memories that ChatGPT may use to personalize responses through sources or in your memory summary. Memories are now updated automatically, with ChatGPT keeping track of the details it determines are most important so it can continue building on the context you've already shared. If you prefer to revert to the legacy saved memories system, go to Settings > Memory > Saved memories. This update is rolling this out to Plus and Pro users in the US today. To access it on iOS or Android, update your ChatGPT app to the latest version. We'll expand to Free and Go plans and additional countries over the next few weeks. Users will receive an in-product notice when the update becomes available to them. For Plus and Pro users, ChatGPT can also remember more useful context, with twice as much memory capacity.

May 05, 2026

ChatGPT Update

Starting today, we're rolling out memory improvements to ChatGPT Plus and Pro users that make responses more personalized, useful, and continuous over time. ChatGPT can now better pull in relevant context from your past chats, saved memories, and, where available, files and connected Gmail app, to offer more tailored ideas, recommendations, and next steps.

Sometimes, you just want the right answer as quickly as possible. We're rolling out Fast answers, a quicker way to get responses to common information-seeking questions in ChatGPT, like 'Show me the Seven Wonders of the World' or 'Which football team has the most super bowl titles?' When your question doesn't require a personalized response and ChatGPT has a high-confidence answer ready, it can now respond faster while still providing a useful, in-depth answer. Fast answers do not reference your past chats or memory. Fast answers are available globally on web, iOS, and Android for logged in and logged out users across plans. If you prefer ChatGPT to always generate personalized answers, you can turn Fast answers off anytime in Personalization settings.

April 09, 2026

GPT-5.3 Instant Mini

Today, we're releasing GPT-5.3 Instant Mini in ChatGPT. It replaces GPT-5 Instant Mini as the fallback model users reach after hitting their rate limits for GPT-5.3 Instant. Because it serves as a fallback, it won't appear in the model picker. Compared with GPT-5 Instant Mini, GPT-5.3 Instant Mini feels more natural in conversation, with stronger writing and contextual awareness throughout chats. It outperforms GPT-5 Instant Mini across a range of use cases.

March 26, 2026

ChatGPT Update

Users can now choose to share their device location so ChatGPT can provide more relevant information, such as local recommendations, news, and weather. Sharing your device location is completely optional and off until you choose to enable it. You can update device location sharing in Settings > Data Controls at any time. Enabling location sharing will also enable precise location. Precise location means ChatGPT can use your device's specific location, such as an exact address, to provide more tailored results. For example, if you ask 'what are the best coffee shops near me?', ChatGPT can use your precise location to provide more relevant nearby results.

March 24, 2026

ChatGPT Update

We've improved shopping in ChatGPT to make it easier to discover, compare, and decide on products. Product results are now more visually rich, with improved detail and relevance.

We've also improved product data coverage, freshness, and speed so results are more up to date and useful. These improvements are rolling out to all ChatGPT users this week. These updates improve how ChatGPT retrieves and presents product information from merchants and other providers using the Agentic Commerce Protocol (ACP).

March 18, 2026

Availability: Rolling out to all logged-in ChatGPT users across consumer and business plans.

March 05, 2026

GPT-5.4 Thinking

GPT‑5.4 brings together the best of our recent advances in reasoning, coding, and agentic workflows into a single frontier model. It incorporates the industry-leading coding capabilities of GPT‑5.3‑Codex while improving how the model works across tools, software environments, and professional tasks involving spreadsheets, presentations, and documents. The result is a model that gets complex real work done accurately, effectively, and efficiently—delivering what you asked for with less back and forth. In ChatGPT, GPT‑5.4 Thinking can now provide an upfront plan of its thinking, so you can adjust course mid-response while it's working, and arrive at a final output that's more closely aligned with what you need without additional turns. GPT‑5.4 Thinking improves deep web research, particularly for highly specific queries, while better maintaining context for questions that require longer thinking. GPT‑5.4 Thinking also has improved context window management that supports its ability to think for longer. Together, these improvements mean higher-quality answers that arrive faster and stay relevant to the task at hand.

March 03, 2026

GPT-5.3 Instant

GPT‑5.3 Instant delivers more accurate answers, richer and better-contextualized results when searching the web, and reduces unnecessary dead ends, caveats, and overly declarative phrasing that can interrupt the flow of conversation. This update focuses on the parts of the ChatGPT experience people feel every day: tone, relevance, and conversational flow. These are nuanced problems that don't always show up in benchmarks, but shape whether ChatGPT feels helpful or frustrating. GPT‑5.3 Instant directly reflects user feedback in these areas.

February 19, 2026

Gemini 3.1 Pro

Building on the Gemini 3 series, we're releasing 3.1 Pro, a smarter and more capable model for complex problem-solving. 3.1 Pro is designed for tasks where a simple answer isn't enough, taking advanced reasoning and making it useful for your hardest challenges.

GPT-5.2 Thinking

Update on thinking time settings for GPT-5.2 Thinking in ChatGPT. Jan 10, 2026: We lowered the Standard and Light thinking time as we observed users prefer faster responses. As part of this update, the Extended thinking setting for GPT-5.2 was unintentionally changed to be lower which we have now fixed. February 3, 2026: We made another small reduction to Standard thinking time based on testing. February 4, 2026: We're restoring the Extended thinking level for GPT-5.2 Thinking to its prior setting, correcting the inadvertent reduction from January. Extended is now back to its prior level.

Responses in ChatGPT are now more visual and easier to scan. For everyday questions, responses may include at-a-glance visuals—like checking your team's latest stats, converting units, or doing a quick calculation. Answers now also highlight important people, places, products, and ideas. You can tap any highlight to open a side panel with key facts and trusted sources, making it easy to understand the context without asking follow-up questions. Rolling out globally on iOS, Android, web.
