The Top 6 Search Engines & The AI Search Engines To Know

For greater than a decade, Google’s share of worldwide search visitors barely moved. It hovered between 91% and 93%, and the website positioning trade constructed its workflow round that actuality.

As of March 2026, StatCounter data reveals Google at 90.01% of worldwide search visitors, with Bing at 4.98%, Yahoo at 1.39%, Yandex at 1.34%, DuckDuckGo at 0.76%, and Baidu at 0.55%.

Google’s share has fluctuated between roughly 89% and 93% since 2015. It dipped beneath 90% in every of the ultimate three months of 2024 and once more in February 2026 earlier than ticking again above that line in March. At Google’s scale, each tenth of a % represents hundreds of thousands of searches.

In the meantime, AI search instruments like ChatGPT and Perplexity are rising quick outdoors of conventional measurement, and platforms like Amazon and TikTok proceed to seize search conduct that by no means touches a conventional engine.

Right here we’ll stroll by means of the highest six serps that account for the measurable search market. I’ll additionally clarify the place AI serps matches into the image and what all of this implies for the place you make investments assets.

1. Google

Google nonetheless leads by a large margin, with 9 out of each 10 searches worldwide operating by means of its engine, based on StatCounter. Alphabet, Google’s mother or father firm, generates most of its income from search promoting and continues to spend money on AI-powered options.

The visitors potential continues to be unmatched, however incomes clicks means competing in opposition to Google’s personal SERP options. Featured Snippets, Individuals Additionally Ask packing containers, native packs, procuring carousels, and AI-generated summaries all sit above or alongside natural outcomes. Paid search prices proceed to rise in aggressive verticals. And even rating within the high three natural positions doesn’t assure a click on the best way it as soon as did.

None of that modifications the maths. Google continues to be the place the visitors is. If you will spend money on one search engine, it ought to be this one. However the price of competing retains rising, and the share of clicks reaching exterior websites is being squeezed by extra on-SERP solutions. Diversification is value severe consideration.

Yahoo Mail, Yahoo Finance, and Yahoo Information nonetheless draw audiences, and people customers typically search throughout the Yahoo atmosphere relatively than switching to Google.

In case you are optimizing for Bing, you’re additionally reaching Yahoo’s viewers.

The algorithms additionally differ. website positioning guides for the Chinese language market sometimes emphasize area age, meta tags, and web page load velocity as rating elements that carry extra weight on Baidu.
