I am using outbrain to publish my blog content . How will i know that a lead generated for a blog content is from outbrain medium

Hi Praveen, 

If you are running Google Analytics on your landing pages, you can use it to break down the results and to post campaign analysis. (ex. source, medium, paid campaigns, device type, browser, etc.)

Also, if you can control the link the send you the traffic, it would be best to use UTM parameters. By using UTM tags you can set up your form to capture those tags and record them along side the lead’s information.

Best,
