SEO result is different from the tag

You may want to talk to the team at Polylang. You’re outputting 美国信用卡指南

Even with perfect code, the best one can do is to give Google what WE want something to say, and still deal with how IT thinks it should be set up. In your case, I’d say there’s code confusion that is causing this. However, it’s possible, even if the code is as best as it can be, that Google will continue to do as Google pleases.

One thing you can try is to “Fetch as Googlebot” and see if Google clears up the problem if you’ve recently made changes to the site/code: https://kb.yoast.com/article/108-fetch-as-googlebot

You said “I’d say there’s code confusion that is causing this.” But what is the confusion? I used Fetch as Googlebot as you recommended, and didn’t see any “美国信用卡指南” word…

Unfortunately, just because Fetch as Googlebot returns the right result, does not mean that Google will not CHOOSE to use other signals in the code to display results in search. That’s Google’s choice and the best we can do is to provide Google with the cleanest code possible to “suggest” how we want it displayed.

You might try posting this issue in the Google Webmaster help forum and seeing if they have any additional advice for you:
