Bing Topics Portfolio: Which Sites See It and What It Shows

October 14, 2026. Microsoft added a beta tab called Topics Portfolio to the AI Performance report in Bing Webmaster Tools on October 13. It groups the grounding queries for which your site is cited in AI answers into broad topics and shows, for each topic, how many citations it draws across all sites, how many sites are cited for it and how many queries it holds. The tab appears only if Bing has sufficient data for your site, and Microsoft says smaller sites may see a shorter list or not see the feature at all.

What the Topics Portfolio tab shows

According to the Bing Webmaster blog, the tab sits next to Citations and Pages inside AI Performance, and everything in it is personalized to your site: the topics and opportunity queries come from your own presence in AI Search, not from a generic list. The landing view lists your topics with three measures:

1. Topic Size: the approximate total citations across all sites for the topic over the selected period, which Microsoft describes as a measure of AI Search demand.
2. Sites Cited: the approximate number of sites appearing for the topic's queries, which shows how crowded the topic is.
3. Queries: the approximate number of distinct grounding queries in the topic.

Below the table, Top Opportunity Queries lists the strongest queries across your whole portfolio where other sites are cited and yours is not, with citation volumes shown as ranges. Clicking a topic opens three cards, for Topic Size, your own citations in the topic and its number of queries, and two tables: Your Grounding Queries, where your site already appears, and Opportunity Queries, where it does not.

The limits Microsoft lists

Microsoft ships the tab with a beta label and asks users to treat the numbers as directional signals for planning, not a precise ledger. It lists four limits: topic classification is AI-generated and can be wrong; topics with too little site presence or ecosystem activity are not shown; branded queries, including a competitor's brand, can appear as opportunities; and Topic Size, Sites Cited and Queries are approximate. Search Engine Roundtable reported the launch with the same sufficient-data condition. Every topic row and opportunity query carries a thumbs up and thumbs down control for feedback.

How to use it for AI search visibility

1. Check whether you have the tab. If it is missing, Bing does not yet have enough data for your site, and the Citations and Pages views are still the place to see which pages Copilot and Bing's AI summaries cite. Our guide to the AI Performance report shows how to read them and why the pages Copilot cites most can differ from the pages Google sends clicks to.
2. Read size against crowding. A topic with a large Topic Size and few Sites Cited is a better content bet than a crowded one, because more AI answers draw on fewer sources.
3. Treat Opportunity Queries as a brief list, after a brand filter. Remove competitor brand names first, then write or expand pages that answer the remaining queries directly. That is the core of the AI search optimization work we run for clients.

Topics Portfolio counts citations, cited sites and queries, and none of its columns is a click count, so pair it with your analytics. Our guide to tracking AI traffic in GA4 covers that half, and for Google's side of AI answers, see how to correct an AI Overview.
