Microsoft Bing

Hey everyone! I’ve compared Bing to the 3 most popular AI search engines - ChatGPT, Google AI Overviews, and Perplexity, and realized exactly why I keep coming back to Bing. So let me explain.

I love using Bing for a bunch of reasons. But, tbh, this has sparked a lot of debate on our team. So, we decided to run some research to figure out who’s actually winning the AI search race, and who’s just making noise.

We looked at how ChatGPT, Google AIO, Perplexity, and Bing Copilot answer user questions. Sure, Bing has its ups and downs, but unlike the others, it has a clear strategy in how it presents content and picks sources.

Let’s break it down:

How many sources does Bing use?

This one matters: Bing is the most concise of all AI search engines. While ChatGPT gives around 10.42 links per answer, Bing only provides 3.13.

But here’s the thing - that’s not a drawback. Bing likes to keep it short and clear. Its average response length is just 398 characters (that’s 4x shorter than ChatGPT.) So it makes total sense that it includes fewer links.

Fun fact: In 573 answers, Bing gave exactly 2 links; that’s its most common pattern. And in 22 answers, it gave none at all. So that's the reason №1 I love Bing: minimal, but on point.

What kind of sources does Bing link to?

If you’re wondering what websites Bing Copilot actually uses, the answer is pretty surprising.

Forget about YouTube - Bing links to it in only 0.86% of cases. Instead, its top source is WikiHow (6.33%). Yup, Bing loves step-by-step guides.

It also frequently links to Indeed, Healthline, WebMD, and Instructables, in other words, practical content, not just theory.

Quick tip for content creators: if your content helps solve problems with clear instructions - Bing is your opportunity.

Does Bing repeat domains?

This was my favorite part of the study. And the answer is: barely.

Bing shows the most diverse selection of sources out of all AI tools. Only 13.47% of its answers include the same domain more than once.

For comparison, ChatGPT does that in 71.03% of cases. So if you’re struggling to compete with giants like Wikipedia or Reddit - Bing might just be your chance to stand out.

What about domain age?

Now this is interesting. Bing cites younger websites (under 5 years old) more than any other AI search engine - 18.85% of its links.

Old domains (15+ years)? Only 31.19%. So if your site is relatively new, Bing gives you a better shot at getting seen.

Style and tone: What’s Bing’s voice?

Bing is all about simplicity and neutrality. It’s the least emotional of all tools, though it sometimes adds a cautious or serious tone when covering topics like health or risks.

In terms of readability, Bing ranks best. Its Coleman–Liau score is 9.94, meaning it writes in a clear, everyday style. Compare that to ChatGPT’s 12.85 - Bing is just easier for most people to read.

Vocabulary and sentence structure?

Bing is the vocab diversity champion (0.54 score). Even in short replies, it avoids sounding repetitive.

Its average sentence length is just 60 characters, which keeps answers crisp and digestible.

It also has the lowest grammatical complexity (0.38); meaning short, simple sentences without complex constructions. Perfect for quick reading.

So, why do I love Bing?

Because it makes sense! Bing doesn’t like fluffy explanations or vague intros. It values clarity, relevance, and usefulness. Its ideal content is:

• step-by-step instructions

• short and helpful advice

• fresh, low-competition websites

• real-life application

And if you’re creating something simple but valuable, Bing will notice. Which, honestly, is another reason I love it: I’m all for giving small, new businesses a chance to shine online.
