Hello,
We apologize for the issues you are facing with the SEO analysis. It seems that Rank Math is unable to identify any common keywords on your page, which can happen for a few reasons. Here are some steps you can take to address these errors:
1. Add Keywords in Your Page Title & Description
Make sure that you have relevant keywords included in your page’s title and description. You can do this by navigating to Rank Math > Titles & Meta > Homepage. Here, you can add the Title and Description for your homepage. If your homepage is set to a static page, you can edit the SEO Title and Description directly from the Rank Math Metabox of that page.

2. Flush SEO Analysis Cache
If you’ve already added keywords but still see the same error, it might be due to cached results. To clear the cache, go to WordPress Dashboard > Rank Math > Status and Tools > Database Tools and click on the Clear SEO Analysis button against the Flush SEO Analysis Data option. After that, run a fresh analysis by going to Rank Math > SEO Analysis and clicking on the Start Site-Wide Analysis button.

3. Check Content Relevance
Ensure that the content on your homepage is relevant to the keywords you want to target. If the content does not contain these keywords, Rank Math may not be able to identify them.
Language Support
Regarding your question about support for Chinese, while Rank Math primarily supports English, it should still function with other languages, including Chinese. However, keyword recognition may vary based on how well the content is optimized.
