I'm looking for a solution for managing leads from Google AdWords landing pages. This solution would need to be able to be used for multiple companies/domains. What I’m looking for is that every time a lead goes through, an email is sent with leads details (date, name, phone, email etc). I’d like to know which keyword brought them there to convert, from which landing page, on which campaign. It would also need to have reporting functionality.
You can simply offer an incentive for them to give you those details. Then you simply use a service like Aweber to collect the information. You can find out which keyword led them to convert by installing conversion tracking and then simply running a report from your Adwords account. Note that you can only get personal details from leads who voluntarily give them to you - you can't make a system get that information for you.
