Google vs Microsoft Bing: A Detailed Comparison Of Two Search Engines via @sejournal, @wburton27

Between Google and Bing, which search engine should you focus on? Should you focus on both or prioritize one over the other?

Google is still the world’s most popular search engine and dominant APP store player, but things are changing quickly in an AI-driven world.

With the rise of artificial intelligence and both Bing and Google incorporating AI – i.e., Microsoft Copilot powered by OpenAI’s GPT-4, Bing Chat, and Google Gemini – into their algorithms and in the search engine results pages (SERPs), things are changing fast.

Let’s explore.

Google Vs. Microsoft Bing Market Share

One of the first distinctions between Microsoft Bing and Google is market share. According to Statcounter, in the US:

• Google fell to 86.58%, down from 86.94% in March and 88.88% YoY.
• Microsoft Bing grew to 8.24%, up from 8.04% in March and up from 6.43% YoY.
• Yahoo grew to 2.59%, up from 2.48% in March and up from 2.33% YoY.

That’s pretty huge to see Bing growing and Google reducing.

Globally

Google had a 91.05% search market share in June 2024, according to Statcounter’s revised data, which is down from 91.38% in March and 92.82% YoY. Google’s highest search market share during the past 12 months, globally, was 93.11% last May.

While that may make it tempting to focus on Google alone, Microsoft Bing provides good conversions and has a user base that shouldn’t be ignored. Bing’s usage has grown because of the AI-powered feature Bing Chat, which has attracted new users.

Bing is also used by digital assistants such as Alexa and Cortana.

Bing has around 100 million daily active users which is a number that you can’t ignore. It’s particularly important to optimize for Bing if you’re targeting an American audience. In fact, 28.3% of online queries in the U.S. are powered by Microsoft properties when you factor in Yahoo and voice searches.

Some have wondered over the years whether Bing is an acronym for “Because It’s Not Google.” I’m not sure how true that is, but the name does come from a campaign in the early 1990s for its predecessor, Live Search.

Another fun tidbit is that Ahrefs recently did a study on the Top 100 Bing searches globally, and the #1 query searched was [Google].

Comparing Google Vs. Microsoft Bing’s Functionality

From a search functionality perspective, the two search engines are similar, but Google offers more core features:

Comparing AI Functionality

How Google & Microsoft Bing Differ In Size Of Index And Crawling

Google says:

“The Google Search index contains hundreds of billions of webpages and is well over 100,000,000 gigabytes in size.”

Even so, not even Google can crawl the entire web. That is just not going to happen.

This is why using structured data is so important, especially now with AI overviews. It provides a data feed about your content so Google can understand it better, which can help you qualify for rich results and get more clicks and impressions.

Microsoft Bing hasn’t released similar figures. However, this search engine index size estimate website puts the Microsoft Bing index at somewhere between 8 to 14 billion web pages.

The two engines have shared a little about their approaches to web indexing.

Microsoft Bing says:

“Bingbot uses an algorithm to determine which sites to crawl, how often, and how many pages to fetch from each site. The goal is to minimize bingbot crawl footprint on your web sites while ensuring that the freshest content is available.”

Around the same time the above statement was made, John Mueller from Google said:

“I think the hard part here is that we don’t crawl URLs with the same frequency all the time. So, some URLs we will crawl daily. Some URLs maybe weekly.

Other URLs every couple of months, maybe even every once half year or so. So, this is something that we try to find the right balance for so that we don’t overload your server.”

Google has a mobile-first index, while Microsoft Bing takes a different stance and does not have plans to apply a mobile-first indexing policy.

Instead, Microsoft Bing maintains a single index that is optimized for both desktop and mobile, so it is important to make sure your site experience is optimized, loads quickly, and gives users what they need.

Google has evolved into more than just a search engine with products like Gmail, Maps, Chrome OS, Android OS, YouTube, and more.

Microsoft Bing also offers email via Outlook, as well as other services like Office Online or OneDrive.

Unlike Google, however, it does not have its own operating system. Instead, it uses Windows Phone 8 or iOS on Apple devices.

Now, let’s take a look at where Bing is on par with Google – or superior.

Differences In User Interface & Tools

Google has a clean, simple interface that many people find easy to use, but for some queries, AI overviews are shown.

So does Microsoft Bing, though Bing is a little bit more visual.

Both search engines display useful information about related searches, images, companies, and news and do a great job of informing users of everything they need to know about a given topic.

SEO professionals love our tools and data.

Thankfully, both Google and Microsoft Bing have decent keyword research tools that offer insights into performance:

One area where I think Google falls behind is the data it provides in Google Search Console. If you want to learn how to use it, check out How to Use Google Search Console for SEO: A Complete Guide.

One of the cool feature sets in Microsoft Bing is the ability to import data from Google Search Console:

Another Microsoft Bing feature that I think beats Google is the fact that it provides SEO Reports.

According to Bing, these reports contain common page-level recommendations based on SEO best practices to improve your rankings.

The reports are automatically generated biweekly and provide tips as to what to work on or investigate.

Microsoft Bing May Excel In Image Search Over Google

When it comes to image search, Microsoft Bing may have a leg up on Google by providing higher-quality images.

I like the filtering features in its image search, too, because you can turn titles off and search by image size, color, or type.

Test out Bing Visual Image Search, which allows you to do more with images. Check out its library of specialized skills to help you shop, identify landmarks and animals, or just have fun.

Google has more images available for viewing than Microsoft Bing. Make the most of it with the tips in A Guide to Google’s Advanced Image Search.

However, Microsoft Bing provides more detailed information about the image users are searching for.

How Microsoft Bing & Google Handle Video Search

Microsoft Bing provides a much more visual video search results page, including a grid view of large thumbnails.

Google’s video results are more standard, featuring a vertical list of small thumbnails.

As you can see from the screenshot of a Bitcoin search below, they include different filters like length, price, etc., which is a great user experience.

I did not get this experience with Google video search.

This is one area where Microsoft Bing outperforms Google.

Map Listings On Both Search Engines Matter For Local SEO

Both engines have similar functionality for maps, including map listings and local listings in the search engine results pages (SERPs).

Make sure you claim all your listings in both Microsoft Bing and Google and optimize your profile with business information, photos, proper categories, social information, etc.

Accurate name, address, and phone number (NAP) information are key. Google focuses on a user’s immediate vicinity by default, providing highly localized search results, while Bing offers a broader view of the wider area in local searches, which can be beneficial for some businesses.

Optimizing For Google Search Vs. Microsoft Bing

Google is primarily concerned with E-E-A-T: Experience, Expertise, Authority, and Trust. Providing users with high-quality, useful, and helpful content that is factual, original, and offers users value, as well as a site that provides good user experience, will help you rank.

Backlinks are also still important.

Microsoft Bing has always been focused on on-page optimization. It emphasizes exact-match keywords in domain names and URLs, gives weight to social signals and official business listings, and favors older and established domains.

Unlike Google, Microsoft Bing states in its webmaster guidelines that it incorporates social signals into its algorithm. That means you should also focus on Twitter and Facebook – including building good quality content on your site and social platforms – if you want to rank highly in Microsoft Bing.

Content is extremely important for both search engines. Always focus on high-quality content that satisfies the user’s intent and informational needs. By creating useful and relevant content, users will naturally love it and link to it.

Both speed, mobile-friendliness, and proper tech infrastructure matter for both engines.

Google Is Pushing Organic Results Further And Further Down The Page

As time goes on, Google continues to push organic results down the page, resulting in more revenue from paid search ads and fewer clicks from organic search. That is why a blended strategy is important to win in today’s SERPs.

Here is a comparison between a search in Google and a search in Bing. As you can see, Bing does not have as many ads as Google, and organic listings are more prominent on the page than Google.

Google Search Vs. Microsoft Bing: The Verdict

Both Microsoft Bing and Google satisfy the informational needs of millions of people every day.

While Google remains the dominant player in the battle between Bing and Google, they both offer opportunities for your brand to reach new users and put you in front of millions of qualified customers who are looking for information, products, and services.

Bing offers unique advantages and opportunities, particularly in visual search, social signals, and certain niche markets.

Bing holds a smaller market share but has a growing user base.

Since optimizing for both Bing and Google is similar, with some key differences, I recommend optimizing for both. This can enhance overall visibility and reach, especially in a world where Google is pushing organic listings further and further down the page.
