Search Engines Bing, Yahoo, Yandex And Baidu
Google covers almost 90%, the search engine market. However, in many countries like China where Baidu is used as the major search engine. In Russia, Turkey, Belarus, and Ukraine, Yandex search engine is very popular. Many times Bing and Yahoo do not index your website or index later.
Furthermore, if your topic is global, for instance, fashion, cooking, blogging, technology, and the computer then check whether your website has got indexed in these search engines or not. If not, you are missing 10% users.
How to get my website indexed in these search engines.
Each search engine provides websites to submit URL for indexing. For instance,
Bing’s submit URL is https://www.bing.com/toolbox/submit-site-url and Yandex submit URL is https://webmaster.yandex.com/site/indexing/reindex/, and if you submit URL to search engines may ask to paste an HTML code to your home, do what they have instructed your websites will get indexed. On the other hand, Baidu requires a contact number of China so if you are not Chinese your website will not be able to get indexed in Baidu.
Below the URL from which you can get an idea.
