The problem
B2B sales cycles are long. A prospect finds you through a Google search, reads a case study, then comes back weeks later from a LinkedIn ad to book a call. Last-click reporting credits the LinkedIn ad and misses what introduced them.
How SourceTag helps
SourceTag records the first click and the last click on every form submission, so you can see what introduced the prospect as well as what brought them back.
What lands in your CRM
Every form submission is tagged as it is sent. Your team reads the source next to the name and the phone number.
Lead source
Channel, source, campaign and keyword. First click and last click on the same record.
Ad click IDs
gclid, fbclid, msclkid and ttclid. Match each lead back to the exact ad that created it.
Visit history
Visit count, days to conversion, device and landing page, so whoever picks up the lead knows the story before they call.
Examples for b2b services
A consultation that started with a Google search and converted via a LinkedIn retargeting ad
An enquiry from a referral partner's website
A contact form submission from a Google Ads campaign targeting a competitor name
Channels set up by default
