Bing AI and Microsoft Copilot: How AI Search Works

Bing AI is the artificial intelligence system powering Microsoft’s search engine and its AI assistant, Microsoft Copilot. Originally built to improve search results through natural language processing and machine learning, Bing’s AI capabilities now form the backbone of Copilot’s conversational search, AI-generated summaries, and content citation systems. ProfileTree, a Belfast-based digital agency, tracks AI search performance across Bing, Google, and ChatGPT as part of our SEO and content marketing services — and Bing’s AI features have become a measurable part of how businesses get found online.

What Is Bing AI?

Bing AI refers to the collection of artificial intelligence technologies built into Microsoft’s Bing search engine. These technologies process search queries, understand what people are actually looking for, personalise results, and — since 2023 — generate conversational AI answers.

Three core technology areas make this work.

Natural language processing allows Bing to interpret what someone means rather than just matching keywords. If you type “how much would it cost to get a website built in Belfast,” Bing’s NLP systems understand you’re asking about pricing, that you want a local provider, and that you probably want ballpark figures rather than an exact quote. This works even with informal phrasing, slang, or grammatical errors.

Machine learning personalises search results based on patterns. Bing’s algorithms learn from search history, click behaviour, and which types of results people find useful. Over time, the search engine adjusts what it shows to match individual preferences. This is why two people searching the same phrase can see different results.

Computer vision handles image-based search. Bing can identify objects in photos, match similar images, and understand visual context. You can search using an image instead of text — useful for identifying products, landmarks, or finding higher-resolution versions of something you’ve seen online.

What has changed significantly since 2023 is how these three systems feed into AI-generated answers. Rather than just ranking web pages, Bing now uses these technologies to generate direct answers inside Copilot, pulling from multiple sources and citing them with clickable links.

For businesses, this matters because intelligent search technology has changed what “being found on Bing” actually means. A page could rank at position 9 in traditional results but get cited thousands of times in AI answers — driving visibility through an entirely separate mechanism.

From Bing Chat to Microsoft Copilot: The Timeline

The journey from Bing as a standard search engine to an AI-powered platform happened quickly. Here is how it played out.

2009 to 2022: Microsoft launched Bing as a search engine in 2009, gradually adding AI features over the following decade. These included voice search, contextual results based on location and activity, and improved image recognition. The changes were incremental, and Bing remained a distant second to Google in market share throughout this period.

February 2023: Bing Chat launches. Microsoft integrated OpenAI’s GPT-4 model directly into Bing, creating “Bing Chat,” a conversational AI built into the search engine. This was the first major search engine to offer AI-generated answers alongside traditional results. Microsoft called the underlying system the Prometheus model, combining Bing’s search index with OpenAI’s language models.

Late 2023: The Copilot rebrand. Microsoft began unifying its AI products under the “Copilot” brand. Bing Chat became Microsoft Copilot, positioned as an AI assistant that works across Bing, Edge, Windows, and Microsoft 365.

October 2024: Major Copilot overhaul. Microsoft separated Copilot from Bing as a standalone product, adding Copilot Voice (spoken conversations), Copilot Vision (visual understanding), and Think Deeper (a reasoning mode using OpenAI’s o1 model). By February 2025, Voice and Think Deeper became free for all users.

April 2025: Copilot Search launches in Bing. This blended traditional search results with AI-generated summaries directly on the Bing results page. Instead of showing only blue links, Bing now provides an AI-curated summary at the top of results for many queries, with cited sources.

October 2025: Personality and personalisation. Microsoft introduced memory features so Copilot could remember preferences across sessions, and added actions that let Copilot perform tasks like booking travel or buying tickets through partner websites.

November 2025: Citation improvements. Microsoft made source citations more visible in Copilot responses, with clickable links and a consolidated “Show all” source panel — specifically designed to support the publishers whose content Copilot references.

As Ciaran Connolly, founder of ProfileTree, puts it: “The speed of change in AI search has caught most businesses off guard. Three years ago, nobody was thinking about whether their website would get cited in a Copilot answer. Now it’s a measurable part of search visibility, and we’re building it into every content marketing strategy we put together.”

How Copilot Search Works in Bing

Copilot Search combines Bing’s search index with Microsoft’s AI models to generate answers. When you search for something on Bing, the system decides whether to show traditional results, an AI summary, or both, depending on the complexity of the query.

For simple, factual queries — a sports score, a stock price, a currency conversion — Bing still shows a direct answer with standard web results. For complex or multi-part questions, Copilot Search generates a summarised answer that pulls from several web sources, displays them as cited references, and offers follow-up questions you can click to continue exploring.

What Copilot pulls from when generating answers:

Copilot uses Bing’s web index to ground its responses in real sources. It selects content based on relevance, recency, and authority. Pages with clear, factual statements structured under descriptive headings tend to get cited more frequently than pages with vague or promotional language. According to Ahrefs’ research, pages covering multiple sub-questions within a single topic are 161% more likely to appear as AI citations.

How citations work:

When Copilot generates an answer, it includes numbered citations linked to the source pages. Since November 2025, these citations appear more prominently, with publisher names visible and a side panel showing all referenced sources.

Copilot across Microsoft’s ecosystem:

Copilot is not limited to Bing. The same AI appears in Microsoft Edge (as a sidebar assistant), Windows 11 (through the taskbar), and Microsoft 365 applications, including Word, Excel, PowerPoint, and Outlook. In business contexts, Microsoft 365 Copilot can summarise meetings, draft emails, analyse spreadsheets, and create presentations. From July 2026, Microsoft is bundling more Copilot features into standard Microsoft 365 subscriptions.

For SMEs in Northern Ireland and across the UK, understanding how Copilot Search operates is increasingly relevant to content strategy. The businesses that show up in AI answers are not always the ones with the most backlinks — they are often the ones whose pages answer specific questions clearly and factually.

Bing AI vs ChatGPT: Which Is Right for Your Business?

The two tools serve overlapping but distinct purposes, and confusion between them is common. Here is a straightforward comparison.

For most Belfast businesses using Microsoft products, Copilot is the natural starting point — particularly given its free access tier and built-in integration with Edge and Windows. ChatGPT tends to be better suited to extended writing tasks or software development workflows.

One important practical note: Copilot’s Creative mode is optimised for brainstorming and creative writing, but it is more likely to produce inaccuracies than Precise mode. For factual research, market data, or anything you plan to publish, always use Precise mode and verify the cited sources independently.

Privacy and GDPR considerations for UK businesses:

Microsoft offers Bing Chat Enterprise, which processes queries without retaining data to train AI models. For UK and EU businesses subject to GDPR, this matters — standard consumer versions of AI tools may handle data differently. If your staff are using Copilot for client-related work, the enterprise tier or Microsoft 365 Copilot with appropriate data governance policies is the appropriate route.

Tracking AI Search Performance: The Bing Webmaster Tools Dashboard

On 9 February 2026, Microsoft launched the AI Performance dashboard in Bing Webmaster Tools, giving website owners the first real data on how their content performs in AI-generated answers.

This is significant because, until now, there was no way to measure AI search visibility with first-party data. Google Search Console includes AI Overviews in its general performance reporting, but does not offer a separate AI citation report or show which specific pages get cited. Bing’s dashboard goes further by tracking citation counts at the page level, showing which queries triggered citations, and allowing you to see trends over time.

What the dashboard shows:

The AI Performance report includes five core views. Total citations show how often your site appears as a source in AI answers during a chosen time period. Average cited pages shows how many of your pages are being referenced per day. Grounding queries reveals the phrases the AI used when retrieving your content. Page-level data shows exactly which URLs are getting cited and how often. Trend data lets you track changes over time.

What this means in practice:

For any business tracking its digital marketing performance, this dashboard adds a new dimension. You can now see whether your content strategy is producing pages that AI systems find worth citing, which topics you are being cited for, and whether your citation counts are growing or declining.

At ProfileTree, we have started incorporating Bing AI citation data into our content audits alongside Google Search Console performance. The two datasets reveal different things: Google data tells you about traditional ranking performance, while Bing’s AI dashboard tells you whether your content structure and factual depth are sufficient for AI systems to use as a source.

The data is still in public preview, and Microsoft has indicated that more metrics will follow throughout 2026. The grounding queries in particular are still being refined — they represent the phrases Copilot uses when retrieving content, not necessarily the exact queries users typed.

Practical steps for monitoring AI citations:

To access the dashboard, log into Bing Webmaster Tools and click “AI Performance” in the left navigation. If you haven’t verified your site ownership, you’ll need to do that first using XML file upload, a meta tag, or DNS verification.

Once inside, sort your pages by citation count to identify which content AI systems reference most frequently. Look at the grounding queries to understand what questions are driving citations. If your highest-cited page covers a topic you want to be known for, that is a positive signal. If your most-cited pages cover topics unrelated to your core services, it may indicate a content strategy misalignment worth investigating.

For content that is not getting cited, check whether it answers specific questions clearly, uses descriptive headings, includes factual statements AI can extract, and stays current. Microsoft’s own guidance recommends keeping content accurate and up to date, using IndexNow to notify search engines of changes, and maintaining accurate business information through Bing Places.

Troubleshooting Common Bing AI Issues

Bing AI does not always behave as expected. Here are the most common problems and how to fix them.

“Something went wrong” or chat not loading: This almost always relates to account status or browser cache. First, check that you are signed into a Microsoft account — Copilot requires one for extended conversations. Then clear your browser cache and cookies, particularly for microsoft.com and bing.com domains. If the issue persists in Edge, try accessing Copilot via copilot.microsoft.com in a private browsing window.

Responses that feel overly cautious or blocked: Copilot has built-in safety filters that sometimes trigger on legitimate queries. Rephrasing your question more neutrally often resolves this. Switching from Creative to Balanced or Precise mode can also help, as Creative mode applies different content handling.

Can’t access Bing AI on Chrome or Firefox: The Copilot sidebar is exclusive to Microsoft Edge, but the full web interface is available at copilot.microsoft.com and works in all major browsers. Mobile users can download the Microsoft Copilot app on iOS and Android for a similar experience.

Answers that contain factual errors: This is an inherent limitation of AI-generated search, not a bug. Always verify specific facts, statistics, or quotes against the cited source links. Precise mode reduces this risk compared to Creative mode, but it does not eliminate it.

Image generation not working: Image generation within Copilot requires a Microsoft account and uses a daily credit allowance. If you have exhausted your credits, generation slows significantly. Copilot Pro subscribers receive a higher credit allocation.

What Bing AI Means for Businesses

AI search is not replacing traditional search — it is adding a new layer on top of it. Businesses still need pages that rank well in standard results, but they also need content that AI systems can understand, cite, and recommend.

For SMEs in Northern Ireland and across the UK, this creates both a challenge and an opportunity. The challenge is that AI answers can satisfy a user’s query without them clicking through to your site. The opportunity is that being cited as a source in AI answers builds visibility and credibility in ways that traditional rankings do not.

Any sector where people ask complex questions online — including professional services, legal advice, healthcare, property, education, and financial planning — is already seeing significant AI search activity. When someone asks Copilot ,”what does a web designer in Belfast charge?”, the AI pulls from pages that clearly state pricing ranges, service descriptions, and location-specific information.

For location-based businesses, accurate information across Bing Places, your website, and directory listings becomes even more important when AI systems generate local recommendations. Consistent name, address, and phone number data helps AI systems connect your business with relevant local queries — a point that applies equally to Google’s AI Overviews.

The businesses best positioned for AI search are those producing content that is factually specific, regularly updated, clearly structured around real questions, and genuinely relevant to a defined audience. That is not a new content principle — but it is one that AI search is now actively rewarding in measurable ways.

If your business wants to understand how it currently performs in AI search across both Bing and Google, ProfileTree’s SEO services include AI citation analysis as part of our content audits. Our content marketing work increasingly focuses on structural and factual depth — precisely the qualities that determine whether your pages get cited in AI answers.
