Here are the results:
Let’s start with Yahoo, Bing, and AOL, which are responsible for 35% of search queries in the US.
Yahoo, Bing, and AOL
Even though Yahoo and AOL were here long before Google, they’ve obviously fallen behind its powerful algorithm and don’t invest in crawling and indexing as much as Google. One reason is likely the relatively high cost of crawling and indexing the web compared to the popularity of the website.
Google can freely invest millions of dollars in growing their computing power without worrying as much about return on investment, whereas Bing, AOL, and Ask only have a small percentage of the search market.
However, Microsoft-owned Bing isn’t out of the running. Their growth has been quite aggressive over last 8 years:
Unfortunately, we can’t say the same about one of the market pioneers: AOL. Do you remember the days before Google? This video will surely bring back some memories from a simpler time.

DuckDuckGo and Yandex
Both DuckDuckGo and Yandex had no problem indexing all the URLs within http://jsseo.expert, but unfortunately, the only content that was indexed properly was the 100% HTML page (http://jsseo.expert/html/).
Despite my best efforts, I didn’t manage to index http://jsseo.expert in Baidu.com. It turns out you need a mainland China phone number to do that. I don’t have any previous experience with Baidu, so any and all help with indexing our experimental website would be appreciated. As soon as I succeed, I will update this article with Baidu.com results.
Going beyond the search engines
Regardless of the search engine, yet again we come back to testing and experimenting as a core component of technical SEO.
For now, stick to HTML & CSS on your front-end. 🙂
