Chrome Web Store summary hook in 132 characters
Write the 132-character summary as the buyer's first job-to-be-done sentence, because Chrome shows it on the homepage, category pages, and search results before the long description gets a chance.
Why this can grow a startup
A lot of extension teams treat the summary like a metadata field and save the actual explanation for the full description. Chrome does the opposite. It pushes that short line into the main discovery surfaces where the buyer decides whether to click. That means the summary is closer to a search snippet than a subtitle. A plain sentence about the core job usually beats a stuffed list of features because it tells the user whether this extension belongs in their workflow at all.
Company example
Chrome's listing guide says the summary is the main description users see from the homepage, category pages, and search results, and limits it to 132 characters.
