Bing and Google have the 2 highest usage rates amongst search engines in the world. Google currently dominates the search engine market share by owning a 92.9% share of the market, whilst Bing owns 3.03%. These search engines do have some similarities, however at their core they have different algorithms and ranking factors which impact the search engine results pages (SERP).
It is also important to note that advancements in AI technology have allowed both Bing and Google to look at how we use search engines now and into the future. Comparing Bing SEO vs Google SEO can help you understand how you can best optimise your website for both search engines.
