Do I need an app to use web attribution?

No. Web attribution measures what happens on your website, such as visits, sign-ups and purchases, and credits it to the source that brought each visitor, so no app is involved. It is a different job from web-to-app attribution, which follows a click through the app store to an install. In Linkrunner, choose Website when you create a project for a website on its own, or Both if you also have an app or plan one. A web-only project keeps the app tabs locked until a store listing is added, so you can start with the site and add an app later. The Web SDK that powers this is in beta and installs as a script tag or in Next.js. Website-only teams such as SaaS, content and ecommerce are a common fit.
