I check my serp rankings for a keyword and it's #9 on two computers, while #2 on another. This is without any "personal" search options enabled. Why is this going on?
Google sets some personal settings even when you're not signed into your account. The main difference is data sharing between services, which isn't as extensive.
This is from different computers all on the same connection. I'm #2 on a computer that I never used to search for the term. That's what I don't get...Which would be the ranking people would see?
