I have been struggling to improve my SEO ranking for the main keyword and believe these garbled headings would be the culprit. They all display fine on the site, http://stylusdesign.co.jp/. However, if I check to see all the headings on this tool, English characters are fine but Japanese ones are not,
I tried different Google Japanese fonts and they didn’t work either. I also tried someone’s else Japanese website on that tool and their headings are all fine.
My SEO ranking has never been good for the main keyword as I expected and can’t think of anything else at this moment. Please help.
