Google introduced Re-marketing to their Adwords platform quite a while ago, yet it still seems to be a little known feature.
Re-marketing is INCREDIBLY effective though.
With regular PPC, you have ads showing, which people see when searching for specific search terms, and when they see your ad, you hope that they will click on the ad, get to your website, and enter your marketing funnel.
The gist of the Re-marketing system is that anyone who DID come to your website through your PPC campaign, becomes part of a very select audience for the Display Network.
This lets you run secondary ads that only these people will see, giving you additional chances to capture their attention, and getting them into your marketing funnel.
I have seen this implemented most effective with hotel websites.
I searched for a hotel in New York, saw an ad and clicked through. But then I don’t book a room, and continued my journey on the Internet.
Suddenly I saw all sorts of ads from this same New York hotel offering enticing specials, on just about every website I went to.
This is a good marketing practice, and can SUBSTANTIALLY increase your revenues from Pay-Per-Click.
