That would only work if you set the URL parameter and sent the leads an email with that link.
If you prefer, you can use a filter:
Visits Web Page IS X
perhaps that is what you mean. This only works if we already know the lead's info.
Yes, those filters are just what I was thinking:
- Visits Web Page is any
- Company Name is ACME 123
Since we only want to know what known leads/leads in our database are doing, this should work.
