Grow your userbase by adding a "powered by" link to your website or product.
Powered by links are a great way to grow your userbase without having to do any extra work. This tactic was famously used by Hotmail in 1996, when they added a tagline to the end of each outgoing email that said "Get Your Free Email at Hotmail." When the recipient clicked on the link, they were directed to a page where they could set up their own account. Within 6 months, Hotmail had grown to 1 million users. Today, this tactic is still commonly used by website builders, email marketing services, and other tools that allow you to embed content. It usually takes the form of a "powered by" link on a sticky widget or in the footer of a website. This link can be used to direct users to your website or product, and can be a great way to grow your userbase without having to do any extra work.
