Our site does not create User id etc. So I wanted to know if their was a way to create a visitor id or cookie in DTM so that each time a visitor comes to our site an id would be created so that it can be tracked in an evar and used for conversion.
Is this possible? It definitely seems like it's something that DTM should be able to provide.
We do have something called Marketing Cloud Visitor Id Service which can be be deployed through DTM. The ID service provides a universal, persistent ID that identifies your visitors across all the solutions in the Marketing Cloud.
