Hey there @topologiefelix , [this is gonna be slightly long but bear with me]
I hope you are not using US version’s metadata because that will confuse Google and it may end up displaying the output that we are seeing in the search results.
Usually, the US version of a site has bigger domain authority, given it has more backlinking, or visitors (if that’s the case). This can happen despite having good Korean-oriented tags.
So, ensure you’re using a more native approach in developing the Korean version of the HTML tags and metadata and aren’t using anything word-by-word from the US version. Focus more on localization of tags with Korean. Generate good backlinks for the Korean site too.
Now, I inspected your website and found that the basic elements are properly set. However, I found hreflang missing. When you don’t add hreflang, Google usually gives more preference to the US version.
You can add the following to the HTML markup -
This will inform Google to display specific versions to the specific audience of the particular region. US version to the US and Korean version to Koreans. Try re-running on Google Search Console too for indexing.
Another thing, ensure that you’ve kept and slightly different and unique from each other. I am unsure if they are, I am just generally recommending this.
Now, if you want to improve your product listings on Google Shopping ads and manage product inventory, I recommend trying AdNabu. It uses AI optimization to improve product titles and descriptions for your Shopify products, boosting your product reach and improving conversions.
It also supports all 30+ Google Merchant Center languages (including Korean), so you can display your products in Korean, too.
Hope this helps!
