Who will be able to see your ads if you select only “English” in language settings?

Google Ads determines who sees your ads based on the language settings of their web browser, not their spoken language or the language of their search query. If you select "English" in your campaign's language settings, your ads will be eligible to show to users whose browsers are configured to English, regardless of whether they are currently searching in English or if English is their native language. This ensures that your ads are displayed to users who are likely to understand them based on their browser's interface language. The other options are incorrect because Google Ads does not have a mechanism to detect a user's spoken language, and while searching in English is common for English browser users, it's not the direct filter.
