Monetizing your Google Web Stories can be done in a few different ways.

Advertisements: One of the most common ways to monetize content is through advertising. You can include Google AdSense ads within your web stories, which will display ads relevant to your content. Google will also help you to optimize your ad layout to increase revenue.
Sponsored content: Another way to monetize web stories is through sponsored content. You can reach out to brands and businesses that are interested in promoting their products or services within your stories. This can be done through paid partnerships or sponsored posts.
Affiliate marketing: You can also monetize your web stories through affiliate marketing. This involves including affiliate links within your stories and earning a commission for any sales made through those links.
Subscription-based content: Another way to monetize your web stories is by creating exclusive, subscription-based content. This can be done by creating a membership program that offers exclusive content to paying members.
E-commerce: You can also use web stories to promote and sell your own products or services. This can be done by including links to your e-commerce website within your stories.
