Proactive actions against phishing

[sfmailsbm () gmail com]

Dear List,
Supose I have an Internet Banking website, and wanted to know if there are any phishing sites out there, before clients 
start complaining 

Is there any means by which I can search the web to identify fake sites trying to imitate mine?

Will google search option "Find pages similar to the page " be of any help?

Thanks for your suggestions

We are trying to be a little proactive here by trying to identify phishing sites and taking actions before clients are 
infected
