The extension can generate revenue in different ways, such as through sales, advertisement, or by charging for memberships. Additionally, some developers provide their extensions free of charge. They only monetize the extension by showing advertisements within it. Developers may also choose to sell an extended version as a single charge or subscription payment for using it.
This is not limited to developers alone; even affiliates can make money from affiliate marketing whereby they are paid a commission for every purchase that they generate points. This is made possible by using affiliate links that are included in the description of the extension and will redirect users directly to the product page for them to buy the item. Additionally, developers can generate revenue for these extensions by selling virtual items and services using in-app purchases.
Overall, there are multiple means of making money through Chrome extensions. Developers only need to make a selection of the most appropriate monetization approaches depending on their add-on and potential user base. They have great possibilities to earn significant passive income using their Chrome extension through effective strategies.
