If you're looking to effectively track your marketing and sales efforts, it's essential to have a robust attribution system in place. HubSpot is a powerful tool that can help you with this. HubSpot has some great pre-defined lead source buckets and attribution reports. But if you want to define your own set of channels and create reporting that goes deeper than HubSpot's out-of-the-box capabilities, you'll need to set up custom properties to capture attribution data.
