ObsurfableKeyword-level AI tracking breaks the moment you have more than a dozen prompts. You see query 47 moved without knowing whether your category story improved or one long-tail phrasing got lucky.
On October 13, 2026, Microsoft added Topics Portfolio (beta) inside AI Performance in Bing Webmaster Tools. It groups the grounding queries where your site already appears into thematic clusters — football, taxes, AI chatbots — and layers demand, competition, and opportunity queries on top.
It is the first major platform-native report that treats AI visibility as a portfolio of themes, not a bag of strings.
What AI Performance already showed
Bing’s AI Performance report gives publishers a direct view into how their URLs contribute to AI-generated answers in Microsoft’s ecosystem:
- Which grounding queries triggered your content
- Which pages were cited for each query
- How presence shifts over time
That is query-first — powerful for debugging a single miss, exhausting for strategy.
Topics Portfolio adds the macro shape: where your site is strong, where the ecosystem has demand you barely touch, and where competitors crowd the same theme.
What Topics Portfolio adds
According to Microsoft’s announcement, the beta view is personalized to your site:
| Dimension | What you see |
|---|---|
| Topic clusters | AI-generated grouping of grounding queries into broader themes |
| Demand | How much AI search activity each theme represents in the ecosystem |
| Competition | How contested each theme is |
| Opportunity queries | Suggested queries where your site could grow presence — drawn from your activity, not a generic keyword dump |
Microsoft is explicit: topics and opportunities come from your site’s presence and activity in AI Search, not a static industry list.
That design choice matters. A generic “top 1,000 AI prompts” download tells everyone the same story. Topics Portfolio tries to answer: given where Bing already grounds you, where is the next marginal win?
Beta limitations you should internalize
Microsoft labeled the feature beta and listed constraints worth quoting in your planning docs:
- Classification is AI-generated — queries may land in a theme you would label differently.
- Sparse themes hide — topics with insufficient site presence or ecosystem activity may not appear; smaller sites may see short lists or empty states.
- Numbers are directional — Microsoft asks teams to treat metrics as planning signals, not a precise ledger.
That honesty is refreshing. It also means Topics Portfolio is a prioritization tool, not a board-ready SOV certificate on day one.
Why thematic reporting matches how buyers ask questions
Buyers do not memorize your keyword map. They paraphrase:
- “best CRM for nonprofits”
- “which CRM do charities use”
- “nonprofit sales tool comparison”
Those strings differ; the intent theme is the same. Classic SEO tools cluster keywords for a reason. AI answers amplify the problem because small wording changes can reshuffle brand lists — HR92’s October 13, 2026 Google AI Mode test found 13 of 15 rewordings changed tool lists for one prompt, while a core set of brands still appeared every time.
Thematic clustering is how you report stable signal (how often you appear across paraphrases) without pretending position is stable. That aligns with why rank-style AI tracking fails and with guidance to measure frequency across varied prompts (KPIs beyond CTR).
How to use Topics Portfolio in a weekly workflow
Step 1: Validate clusters with human labels
Export or screenshot your top themes. For each, ask:
- Does this match how we describe the product line?
- Are we accidentally grouped with adjacent categories we do not serve?
Misclassification is expected in beta. Fix content and internal linking on your site to reinforce the themes you want — Bing’s classifier reads grounding evidence from your pages.
Step 2: Sort by demand × gap
Microsoft surfaces demand and competition. Prioritize themes where:
- Ecosystem demand is high
- Your presence is thin
- Competition is not hopeless (you already ground on nearby queries)
That is your AI content roadmap for the quarter — not “write 40 blogs,” but “win the theme.”
Step 3: Tie opportunity queries to page types
Different intents cite different page shapes. Kern and others find vendor and product pages dominate many buyer prompts; listicles still matter on some engines (product vs blog split, question intent and page types).
For each opportunity query in a theme, decide:
- Does this need a comparison page, docs, pricing, or category guide?
- Do we already have a URL that should ground — but does not? (Technical crawl, canonical, or authority issue.)
Step 4: Cross-check other engines
Topics Portfolio is Bing-grounded. ChatGPT, Gemini, and Perplexity can disagree — only a tiny fraction of domains appear across all five major engines. Use Bing’s theme map as one lens, then run the same theme set in your cross-engine tracker.
How this compares to third-party “AI visibility scores”
October 2026 also saw vendors split presence from quality — for example, Lumar’s release separating Presence Rate (“how often do we appear?”) from Quality Score (“how well are we positioned when we do?”). Topics Portfolio is closer to planning geography than a single score: where on the thematic map to invest.
None of these replace reading answers. They reduce the dimensionality of noisy query logs so humans can decide.
Publisher and brand implications
Publishers with broad editorial coverage may see many themes — use the view to decide which verticals deserve AI-first formatting (extractable summaries, clear dates, author entities).
B2B SaaS with narrow product lines may see few themes until grounding grows. That is not failure; it means you need more distinct buyer jobs-to-be-done represented on-site before clustering has signal.
Agencies can mirror Microsoft’s structure in client reports: theme → demand → cited URLs → next page to ship. It matches the agency playbook principle of fixed prompt sets with business-language paraphrases.
How Obsurfable fits
Bing shows your grounding on Microsoft’s stack. Obsurfable’s public corpus lets you compare answers and citations across engines for the same buyer themes — in Explorer and matched to your company in the App. Use Topics Portfolio to prioritize themes; use repeated observations to see whether mentions and citations move after you ship pages.
FAQ
Do I need Bing Webmaster Tools if I only care about ChatGPT?
Yes, if Microsoft traffic and Copilot matter in your category. No tool covers every engine; Bing’s report is incremental, not exclusive.
Will topic names match Google Search Console categories?
Unlikely one-to-one. Treat them as AI-search-specific clusters.
Can I export Topics Portfolio data via API?
Microsoft did not announce an API in the beta post. Plan for manual exports until documented.
Does appearing in a theme guarantee Copilot mentions?
Grounding in Bing’s AI Performance indicates citation contribution in their pipeline — not every downstream UI surface. Still directionally valuable.
Bottom line
Bing’s Topics Portfolio (October 13, 2026) is a beta step toward thematic AI visibility planning: demand, competition, and opportunity queries layered on your real grounding history. Use it to choose which buyer themes deserve new canonical pages — then measure cross-engine mention and citation frequency, not imaginary “AI rank.”
