Imagine your team reports that more keywords are in the top 3 than ever. Organic sessions look stable. But when you talk to sales, they say:
Leads from search feel softer. People say they ‘already read an answer somewhere’ before they even reached us.
What changed?
In between your Google rankings and your website, something new started sitting in the middle - AI search results. ChatGPT, Gemini, Perplexity, AI Overviews, Copilot and dozens of in-app assistants are now the first thing people see, and they often answer the question before the click.
In that world, We’re position 3 for this keyword is only half the truth. The real question quietly becomes:
“When an AI answers this query, are we part of the answer at all?”
That’s exactly what an AI visibility index tries to capture - not just how high you rank in traditional SERPs, but how often and how strongly you show up inside AI-generated answers themselves.
Why Classic SEO Metrics Break In an AI-First Search World
SEO used to be brutally simple in theory:
-
Track rankings.
-
Track clicks.
-
Track conversions.
Everything else was decoration.
Now imagine a user journey like this:
-
They ask Gemini or Perplexity: Best email tool for small agencies?
-
The AI gives a rich comparison, with 4 or 5 tools explained in detail.
-
They click on one or two suggested sites, maybe open a few tabs for later.
-
They go directly to brand pages through branded search or direct navigation.
Where did that journey “start”? Not on your blog. Not on Google’s blue links. It started inside an AI-generated summary - and that summary might have quoted a review site, a Reddit thread, a YouTube video, and one or two vendor pages.
If you only look at classic SEO metrics, you miss:
-
How often your brand or domain appears in those AI summaries.
-
Whether you show up as one of the recommended options.
-
How your visibility compares to competitors inside those AI surfaces.
-
Whether UGC sources are stealing the narrative around your category.
That’s why leaders are starting to ask for AI search metrics, not just SERP metrics. They want to know:
-
Are we being mentioned?
-
Are we being cited?
-
Are we being trusted?
Those questions lead directly to the idea of an AI visibility index - one KPI that turns the messy universe of AI assistants into something you can monitor, improve, and report on.
What is an AI visibility index - In Simple Words
Think of an AI visibility index as your “share of voice inside AI answers”.
Instead of just saying “We rank #2 in Google for ‘best CRM for freelancers’”, you ask:
“When an AI explains ‘best CRM for freelancers’, how present are we in that explanation?”
A basic version of the index might combine signals like:
-
Are you named at all in the answer?
-
How many times are you mentioned?
-
Are you shown as a clickable source tile or citation?
-
Are your pages used as primary references or just “one of many”?
-
Across all your priority keywords, what % of AI answers contain your brand or domain?
You can imagine a simple 0-100 scoring model:
| Level | Reality inside AI answers |
|---|---|
| 0 | You never appear, even for your core topics. |
| 25 | You appear sometimes, usually as 1 of many names. |
| 50 | You appear regularly, but not always as a key source. |
| 75 | You are frequently cited, often recommended explicitly. |
| 100 | For your niche, AI almost always mentions or cites you. |
That composite score is your AI visibility index for a given keyword set, topic cluster, brand, or product line. It will never be perfect, but even a rough, consistent index is better than pretending AI search doesn’t exist.
Once you have this mental model, you can stop asking “Are we doomed by AI?” and start asking a better question: “Where are we invisible, and how do we become one of the default sources AI leans on?”
The Building Blocks of AI Search Metrics You Should Actually Track
To turn the AI visibility index from a concept into a usable KPI, you need to break it down into measurable AI search metrics. The good news is you can start simple and refine over time.
Here are four core components worth tracking:
1. Presence rate
For a defined keyword or topic set:
-
How many AI answers do you appear at all?
-
This could be brand name, domain, or a recognisable product name.
If you appear in 3 out of 10 sampled answers, your basic presence rate is 30%. That gives you a baseline: AI doesn’t forget you completely, but you’re far from being the default.
2. Reference quality
Being mentioned once at the bottom is not the same as being used as a primary reference.
You can score answers manually or with a simple rubric:
-
0 - Not present
-
1 - Mentioned, not cited
-
2 - Cited as one of multiple sources
-
3 - Clearly presented as a key reference or recommended option
Over time, the average of these scores per keyword cluster becomes a powerful signal.
3. Surface diversity
You’re not only fighting for space in one system. Ideally, your brand shows up in:
-
AI Overviews or similar AI modules in search engines.
-
Chat-style answers in tools like ChatGPT / Perplexity.
-
In-app assistants (for your niche) where relevant.
Tracking on how many of these surfaces you appear tells you if you’re overly dependent on one ecosystem.
4. Source mix awareness
Finally, note who AI is using when you’re not there:
-
Are they citing review sites? Bloggers? Reddit? Competitors?
-
Do the same few domains show up again and again?
This isn’t just a visibility problem. It’s a strategic content problem. If AI is regularly pulling from detailed reviews and user-generated content, that’s a hint about the formats you should be investing in.
Once you’re comfortable with these four components, you can roll them up into a single AI visibility index per cluster - something a CMO can read in one line, but that still maps back to concrete actions for your SEO and content teams.
How to Start Measuring AI Visibility Without Fancy Tools
It’s easy to assume you need a full-blown tracking platform on day one. In reality, you can prototype your AI search metrics with a spreadsheet and a bit of discipline.
A simple starting workflow:
-
Pick 20-50 high-value keywords
Include a mix of:-
Core money terms (“best X software”, “[category] tool for [segment]”)
-
Brand terms (“[your brand] review”, “[your brand] vs competitor”)
-
Category questions (“how to choose a [tool] for [use case]”)
-
-
Test them across a few AI surfaces
For each keyword, run it through:-
1-2 search engines with AI results (e.g. AI Overviews where available).
-
1-2 answer engines / AI chat tools.
-
-
Score your presence
For each answer, log:-
Presence: Yes/No
-
Mention count: 0/1/2+
-
Reference quality: 0-3 (using the simple scale above)
-
Surfaces where you appear.
-
-
Calculate a small index
For each keyword:-
Presence rate across tools
-
Average reference quality
-
Number of surfaces where you appear
-
-
Then average those across the whole keyword set to get a rough AI visibility index (for example, a score between 0 and 10 or 0 and 100).
-
Repeat monthly
Track how this index moves when:-
You publish new content.
-
You improve entities and schema.
-
You get more reviews or UGC coverage.
-
This manual phase does two things. It forces you to see your niche through the AI’s eyes, and it gives you a clear spec for what you’d want a dedicated AI SEO or visibility tool to automate later.
Using AI Visibility to Reshape Your Content and SEO Strategy
An AI visibility index is only useful if it changes what you do.
Once you know where you’re invisible, you can look at those queries and ask: “What kind of content is the AI relying on instead of us?”
Common patterns you’ll see:
-
For “best X for Y” queries, AI leans heavily on roundup reviews and comparison pages.
-
For “is [tool] legit / safe?” queries, it pulls from forums, Reddit, Quora, and long-form reviews.
-
For “how to” queries, it often mixes how-to guides + documentation + community Q&A.
That immediately shapes your roadmap:
-
If you want to be cited for “best tools” queries, you need neutral, data-backed comparison pages, not just product pages screaming “we’re the best”.
-
If you want to be trusted for “is it legit” queries, you need real review coverage, case studies, and FAQs addressing objections directly.
-
If you want your brand voice inside step-by-step answers, your docs and how-to content need to be structured, clear, and complete.
Because AI search metrics are closer to how people ask real questions, they also highlight intent gaps in your current content. You might rank on page 1 for a broad keyword, but AI ignores you because you never addressed the actual question users ask in natural language.
Over a few cycles, this shifts your mindset from “write more content” to “write the kind of content AI can reuse faithfully when it helps the user most”.
Where Serplux Fits Into an AI Visibility Index Workflow
Doing all of this manually is fine for a pilot. At scale, it becomes painful.
A platform like Serplux can add value in three big ways when you’re serious about an AI visibility index:
-
Keyword intelligence with AI layers baked in
Instead of treating all keywords the same, Serplux can help you understand:-
Which queries behave like classic SEO (blue links driven).
-
Which are clearly answer-engine dominated - AI boxes, summaries, and assistants.
-
Where UGC sites or review aggregators are shaping what AI says.
-
-
That segmentation alone tells you whether to approach a topic as traditional SEO, answer engine optimization, or a hybrid.
-
Tracking AI search surfaces over time
Rather than sampling once a quarter, you want ongoing visibility.
Serplux can monitor AI search results across your priority keywords and capture when:-
Your domain appears inside AI modules.
-
Your brand is named in generated answers.
-
Specific URLs are used as references or source tiles.
-
-
These recurring observations can then be rolled up into a working AI visibility index dashboard - something you can show in a weekly or monthly SEO report.
-
Connecting visibility to action
Data is only useful if it tells you what to do next. Serplux can sit between insight and execution by:-
Flagging keyword clusters where your AI visibility is low but business value is high.
-
Highlighting what kind of pages AI is favouring (comparisons, FAQs, UGC, docs).
-
Suggesting content opportunities and on-page changes aligned with those patterns.
-
In practice, that means your team isn’t just tracking AI for fun. You’re using structured AI search metrics to decide where to invest content, PR, community, and technical work - and you have a way to show if those bets are working.
The New Reporting Slide Your CMO Actually Needs
Sooner or later, someone in your leadership team will ask a simple question:
“In this AI search world, are we still one of the brands that matter?”
If you still reply with “We’re top 3 for 40% of our keywords”, you’ll feel out of date. The question isn’t just where you rank. It’s whether you’re present in the answers people actually see and trust.
That’s why building and tracking an AI visibility index is becoming a strategic necessity, not a vanity project. It turns vague worries about “AI stealing clicks” into something practical:
-
Here’s where we’re invisible.
-
Here’s where AI knows us but doesn’t lean on us.
-
Here’s where we’re already the default voice.
-
Here’s what we’re doing next to move those numbers.
Traditional rankings won’t disappear - they still matter. But if you want your brand to survive and grow in a world of assistants, overviews, and answer engines, you need a second lens on reality.
Classic SEO tells you how you appear to search engines.
An AI visibility index tells you how you appear to the machines that explain the internet back to your customers.
