Shareable attribution links
Team members generate personal links to share with prospects. Activity is anonymously attributed to the sender — no sign-in required from the prospect.
Attributions
Refer traffic with confidence.
Account members can generate personal links to share with prospects. When someone opens your link, their anonymous session is tied to you for the next 30 days—no sign-in required from them.
Attribution links can empower your sales team to track the source of new business. Team members can see the revenue each prospect generates.
Step 1
Generate
Any team member creates a personal attribution link in the Spectra dashboard.
Step 2
Share
Send the link to a prospect. It includes an embedded attribution token in the URL.
Step 3
Track
When they visit, their anonymous session is attributed to that member. Activity shows up in the Attributions report.
Attribution is session-based and anonymous: Spectra does not capture personally identifiable information from prospects or link their activity to a real name.
Creating a sharable link is as easy as copy/paste.
Log in to your Spectra dashboard and go to settings. Scroll down to the "Sharable Links" section and enter the URL that you want to share with the user. Click "Generate Link" and you're done.
Generate a link
Copy & paste the URL that you want to share into the "URL to share" field.
Then click "Generate link" and Spectra will generate a link for you.
Share the link
Copy the URL generated by Spectra and share it with your prospect. You will notice an attribution token gets added to the URL.
When the prospect visits the URL, their session will be tied to you for the next 30 days. You can see the activity in the Attributions report in your Spectra dashboard.
