DuckDuckGo and Yandex
DuckDuckGo does not have webmaster tools. Turns out that I could kill two birds with one stone – by registering on Yandex I will improve my results in DuckDuckGo. Thanks to r3bl ( Aleksandar Todorović ) for the tip. The actual Yandex process requires you to register at their passport site, and it creates a Yandex email for you. If you want to use your own email for notifications you need to register that email separately. I went through the usual process of adding a new meta tag and verifying on their site, and adding my Yoast-created sitemaps.
The process for Sogou (3% search share in China) was pretty simple as well – go here to start. You will likely need to have a Google Translate or similar browser capability to read the details in your native language if not Mandarin. They also requested I use the version of my site prefixed with ‘www’ and would not take the version without that. I added the Sogou meta tag into my site using the Meta Tag Manager from Marcus Sykes.
Finally I tried to do the same on Baidu (75% search share in China) but ran into a bunch of problems. First, they want a China mobile phone. Then I tried to use their Baidu app/QR code process but that ended up at the same dead end. See here for info. There used to be email options for setting up but it seems those have been deprecated. This might not be a problem since I was already getting users from China through cn.bing.com (English search results in Baidu use the Bing search engine and the results are displayed in Baidu’s search result pages.) If I want to reach Baidu users for some future commercial purpose I can always setup a website located in China.
