How to make personalization faster?

I have a lead list of realtors with their Profile URL, Name & Emails. Problem is I need to check their profile URLs one by one to check if they have a website or not. [My offer is web dev] 

Wanted to ask if you know a faster way to do this? Ik it’s kinda a no brainer option to just manually check. But there might be another way to do this better, so I’m looking to get any insights.
