Why it matters
Said at Search Central Live by a community speaker: Persian and Arabic run right to left and English left to right, so a title, product name or URL that mixes the two can display in a confusing, unpredictable order even when its content is correct.
How to meet it
Set lang and dir="rtl" on the html element of right-to-left pages, wrap embedded left-to-right fragments (brand names, model numbers) in bdi or an element with dir="ltr" or dir="auto", and generate titles so the main language comes first. Keep URL slugs in one script per language.
How to test it
Review the title, h1 and product names of key right-to-left templates in a browser and in search results: words, numbers and punctuation appear in the intended order.
How Regensbot covers it
Regensbot proposes a verdict with the evidence; a person on your team confirms it.
The evidence comes from your verified site: its pages, its profile and the files you upload.
You verify the site by a DNS TXT record, a meta tag or a file. Regensbot then keeps a checklist item for this requirement, with a state, a guide, an evidence upload and reminders.
