I am revamping my whole site in reactjs with server-side rendering. In the process, I am replacing all HTML entities in title and meta tags with Unicode.

  • Old title example:

    This is a » Title

  • New title:

    This is a » Title

Will it cause any negative impact on SEO?

Short answer: No, it will not impact you negatively.

Long answer: Unicode is just a representation of characters from U+0000 to U+10FFFF. Nothing more. Google is able to understand that just as well as any other standard represention of characters. If you asked "how SEO friendly unicode URLs are", well that would be a matter of taste, language and target market. Amazon Japan uses unicode characters in their URLs due to nonexistent and/or unreadable URLs in ASCII representation. Same goes for some non-latin character languages such as Arabic, Hebrew, Farsi, Chinese, etc.

  • I agree with this. Google is already decoding your entities. Using unicode instead is equivalent from Google's perspective. Google has always been very good about this. When Yahoo ran its own search engine however, they couldn't deal with entities in titles or meta descriptions properly. – Stephen Ostermiller Jun 20 '18 at 14:54
