Screenshots should reflect the most up-to-date functionality corresponding to the latest version of the extension. Screenshots should demonstrate the actual user experience, focusing on the core features and content so users can anticipate what the extension's experience will be like. You must provide at least one-and preferably the maximum allowed five-screenshots of your item to be displayed in the store. Use screenshots (or videos) to convey the capabilities, look and feel, and experience of your item to users. See more examples of icons that follow the correct guidelines on the extension icon best practices page. These details can be very hard to see in small sizes. Ensure the most important text is included in your summary to help users understand what they can expect from your item in a quick glance. This is the main description of your item users see from the homepage, category pages and in search results. Your summary is used to give an overview of your item in a concise phrase (132 characters or less).
The following sections explain how to make best use of these text fields.
There are two main text resources that you can use to make your listing compelling: The item summary and the item description. You can build and maintain your store listing page using the developer dashboard. A quality listing page clearly communicates what your item will offer, using the item description, images, and other listing metadata. Build trust with users by making a strong first impression, with a compelling and accurate store listing page. Our focus on surfacing quality items to users encompases the entire user experience-this includes the store listing page.
Making sure yours is a "quality item" can help ensure its prominence in the store, potentially increasing your user base.
The Chrome Web Store works hard to help users discover and install quality items.
