What low-investment strategy could a channel try to increase viewership (and ad revenue) in another country?

Crowdsourcing captions and metadata translations is a low-investment, high-impact strategy. Many viewers are willing to contribute translations for content they enjoy, making videos accessible to a wider international audience without significant cost to the creator. This directly increases viewership and, consequently, ad revenue from those new viewers. Identifying local talent and creating dubbed versions, or re-creating videos with top creators, are high-investment strategies requiring significant financial and logistical resources. Doing nothing is incorrect; increased international viewership absolutely impacts ad revenue by expanding the potential audience for advertisements.
