Why Bing Optimisation Is the Most Underrated GEO Tactic for Singapore SMEs

Bing Quietly Powers the Non-Google AI Ecosystem

When Singapore SMEs think about search visibility, they think about Google. That makes sense — Google dominates traditional search in Singapore. But the AI search landscape is different, and the difference creates one of the most overlooked opportunities in GEO.

Here is the reality: Bing quietly powers most of the non-Google AI ecosystem. ChatGPT’s live search runs on Bing. Microsoft Copilot is built on Bing — same index, same gate. Many smaller AI search products license Bing’s index rather than crawling the web themselves. Bing is the only serious alternative index to Google, and it feeds the AI tools your customers are increasingly using to find businesses.

The SME-pitch version is simple: everyone optimises for Google; almost nobody optimises for Bing — yet Bing decides whether ChatGPT can recommend you. It is the cheapest arbitrage in GEO right now.

ChatGPT Search Runs on Bing

ChatGPT generates recommendations from two sources: its training corpus (everything it learned up to its training cutoff) and live web browsing. When a user asks for a business recommendation and ChatGPT needs current information, it browses the web. And when it browses, it uses Bing.

This is because of OpenAI’s partnership with Microsoft. The search infrastructure behind ChatGPT’s browsing mode is Bing’s index. Studies that have analysed ChatGPT’s citations show that approximately 87% of them match Bing’s top results for the same query. That is not a coincidence — it is a direct dependency.

The implication is stark: if your business is not in Bing’s index, ChatGPT cannot cite you. No matter how good your content is. No matter how strong your Google rankings are. No matter how much you have invested in your website. If Bing has not indexed your pages, ChatGPT’s browsing mode will not find them, and you will be absent from its recommendations.

This is why businesses that invest heavily in Google SEO but ignore Bing are leaving ChatGPT visibility on the table. They rank well on Google, but when a potential customer asks ChatGPT for a recommendation and it browses the web, their business simply does not exist in the index ChatGPT is searching.

Copilot Is Bing — Literally

Microsoft Copilot is built on OpenAI’s language models and grounded by Bing’s search infrastructure. When a user asks Copilot a question, it runs a Bing search, retrieves results, and generates a grounded answer. Copilot does not have a separate index or a separate crawler — it is Bing, with an AI layer on top.

This means the same Bing index that feeds ChatGPT’s browsing also feeds Copilot directly. If Bing cannot find your business, neither ChatGPT nor Copilot can recommend it. One index, two of the most important AI engines, both gated by the same requirement: you must be in Bing.

Copilot is also embedded across Microsoft’s ecosystem — Edge browser, Windows search, and Microsoft 365 apps used by the majority of Singapore enterprises. When a corporate buyer uses Copilot inside Teams or Excel to research a vendor, the results come from Bing. This makes Bing visibility especially important for B2B and professional services in Singapore.

Other AI Tools Lean on Bing’s API Too

The Bing dependency extends beyond ChatGPT and Copilot. Many smaller AI search products — and historically services like DuckDuckGo and Yahoo — license Bing’s index rather than maintaining their own web crawler. Building and running a web-scale crawler is enormously expensive; most companies choose to license instead.

This means that when you optimise for Bing, you are not just optimising for two engines — you are optimising for a whole layer of the AI search stack that depends on Bing’s API. New AI search tools that launch tomorrow are likely to license Bing’s index too, because the alternative (building their own crawler) is prohibitively expensive for all but the largest companies.

Bing is the only serious alternative index to Google. If you want AI visibility beyond Google’s ecosystem (Gemini, Google AI Overview), Bing is the foundation.

The Perplexity Exception

Perplexity is the notable exception. Unlike ChatGPT and Copilot, Perplexity runs its own crawler and maintains its own index. It does not depend on Bing. This means Bing optimisation alone will not guarantee Perplexity visibility — you also need to be crawlable by Perplexity’s bot and present in the citation-worthy sources it favours (Reddit, Quora, press, review aggregators).

However, Perplexity is one engine. ChatGPT and Copilot — both powered by Bing — represent a much larger combined audience. Optimising for Bing covers the majority of the non-Google AI ecosystem; optimising for Perplexity’s crawler covers the rest.

The full picture: Google’s index feeds Gemini and Google AI Overview. Bing’s index feeds ChatGPT, Copilot, and the long tail of Bing-API-dependent tools. Perplexity runs its own. Three indexes cover essentially the entire AI search landscape. Most Singapore SMEs only invest in one (Google). Bing is the second — and it is the one almost everyone is ignoring.

Why Almost Nobody Optimises for Bing

If Bing is so important, why is almost nobody optimising for it? Three reasons:

• →Bing’s search market share is small. In Singapore, Bing accounts for a small fraction of traditional search traffic. Most SMEs see no reason to invest in a platform that sends them little direct traffic. What they miss is that Bing’s value is not in its search results page — it is in the AI engines that depend on its index.
• →The Bing-AI connection is not widely known. Most business owners do not realise that ChatGPT’s browsing is powered by Bing. They think of ChatGPT and Bing as completely separate products. Once you understand the dependency, the case for Bing optimisation becomes obvious — but that understanding is not yet common.
• →SEO agencies focus on Google. Most SEO agencies and tools are built around Google optimisation. Bing is treated as an afterthought, if it is considered at all. The entire SEO industry’s tooling, reporting, and incentives are Google-centric, which reinforces the neglect of Bing.

The result: a massive visibility gap. Bing’s index is smaller and less competitive than Google’s, which means the businesses that do invest in Bing stand out — not just in Bing’s own search results, but in every AI engine that depends on Bing’s index.

The Cheapest Arbitrage in GEO

An arbitrage exists when there is a gap between effort and reward — when a small investment produces a disproportionately large return. Bing optimisation is the cheapest arbitrage in GEO right now for three reasons:

• →Low effort: The foundational steps — submitting to Bing Webmaster Tools, submitting your sitemap, fixing basic technical issues — take under 30 minutes and are free.
• →Low competition: Because almost no Singapore SME has invested in Bing, the index is sparse. The same content that ranks on page 3 of Google can rank on page 1 of Bing simply because fewer pages are competing.
• →High leverage: Bing’s index feeds ChatGPT, Copilot, and the long tail of AI tools. A single Bing submission unlocks visibility potential across multiple AI engines simultaneously.

Compare this to Google SEO, where ranking for competitive Singapore keywords can take months of content production, link building, and technical optimisation — with no guarantee of results. Bing offers a fraction of the effort for a different (but increasingly important) set of AI-driven outcomes.

The window will not stay open forever. As more businesses understand the Bing-AI connection, competition in Bing’s index will increase. Right now, early movers can establish Bing authority that compounds over time — the same way early Google SEO adopters built defensible rankings that persist today.

How to Get Indexed in Bing (30-Minute Guide)

Getting your business into Bing’s index is straightforward. Here is the step-by-step process:

1. 01Create a Bing Webmaster Tools accountGo to bing.com/webmasters, sign in with a Microsoft account, and add your site URL. This is free and takes two minutes.
2. 02Verify ownershipBing offers three verification methods: a meta tag in your homepage’s HTML, an XML file uploaded to your root directory, or a DNS CNAME record. The meta tag method is fastest if you can edit your site’s HTML.
3. 03Submit your XML sitemapIn Bing Webmaster Tools, submit your sitemap URL (typically yourdomain.com/sitemap.xml). This tells Bing your full page structure and prioritises crawling.
4. 04Check the Index ExplorerAfter a few days, use Bing’s Index Explorer to confirm which pages Bing has indexed. If key pages are missing, use the URL Submission tool to request indexing directly.
5. 05Fix any crawl errorsBing Webmaster Tools will flag crawl errors — broken links, robots.txt blocks, noindex tags. Fix these so Bing can fully crawl and index your site.
6. 06Submit to IndexNow (optional but recommended)IndexNow is a protocol Bing supports that lets you ping Bing instantly when you publish or update content, rather than waiting for Bing’s crawler to find it. This is especially valuable for time-sensitive content and fresh blog posts.

That is it. The entire process takes under 30 minutes for most sites, and it unlocks Bing visibility across ChatGPT, Copilot, and every AI tool that depends on Bing’s index.

Bing SEO vs Google SEO: What’s Different

Bing and Google use different ranking algorithms. While many fundamentals overlap (quality content, clean technical structure, schema markup), there are important differences to know:

• →Exact-match keywords matter more in Bing. Google has moved toward semantic understanding, but Bing still gives weight to exact keyword matches in titles, headings, and content. This makes keyword targeting more straightforward.
• →Social signals carry more weight in Bing. Bing has stated that social media engagement (shares, likes, visibility on social platforms) is a ranking factor. Google has downplayed social signals.
• →Click-through rate (CTR) matters more in Bing. Bing uses CTR as a ranking signal more explicitly than Google. Compelling meta titles and descriptions can boost rankings.
• →Backlinks are weighted differently. Google prioritises link quality and authority heavily. Bing values backlinks too, but places more emphasis on anchor text relevance and the contextual match of the linking page.
• →Both support schema.org. The same structured data vocabulary works for both engines. If you have schema markup for Google, Bing can read it too.

The good news: most of the work you do for Google SEO — clean site structure, quality content, schema markup — also helps in Bing. The main additional work is ensuring Bing has actually indexed your pages, which is where Bing Webmaster Tools comes in.

Common Bing Mistakes Singapore SMEs Make

• →Never submitting to Bing Webmaster Tools. This is the most common and most damaging mistake. Bing may eventually crawl your site on its own, but without active submission, indexing is slow and incomplete.
• →Assuming Google rankings transfer to Bing. They do not. Bing and Google maintain separate indexes. A page ranking #1 on Google may not be indexed in Bing at all.
• →Blocking Bing’s crawler in robots.txt. Some sites inadvertently block Bingbot or set aggressive crawl-delay rules that prevent Bing from indexing their content effectively.
• →Not using IndexNow for fresh content. Without IndexNow, Bing discovers new content only when it next crawls your site. For time-sensitive articles, this delay can mean missing the window when a topic is trending in AI search.
• →Ignoring Bing’s crawl errors. Bing Webmaster Tools reports crawl errors that Google Search Console may not flag. Ignoring these means pages that should be indexed are not.

The Bottom Line

Bing is the most underrated tactic in GEO — not because Bing’s own search traffic is large, but because Bing’s index feeds ChatGPT, Copilot, and a long tail of AI search tools. The businesses that understand this and invest in Bing visibility now will have a structural advantage in AI search that compounds as AI adoption grows.

The cost is low — 30 minutes and a free Bing Webmaster Tools account. The opportunity is large — visibility across multiple AI engines that most of your competitors are completely ignoring. And the window is open now, before the rest of the market catches on.
