Organic lead source problem - main referrer is our own site
I'm trying to understand why the Original Referrer field is showing our own website, and our 2 subdomains (marketo pages and blog) as our original referrer. Out of 2300 leads created the past 3 months about 2100 have our own website listed as the original referrer. I just inherited this instance of Marketo, so I don't know where I should be looking to try to fix this problem. Does anyone else have this issue? Or can you provide me with some clues on what could possibly be causing this? Any help is appreciated! Thank you!
