Can Anyone Help Me On Retargeting, Pixels etc I need to learn That stuff

Digital Marketer has a ton of free info on retargeting on their blog.

Re-targeting is where it is at these days. If your not retargeting your throwing money out the window on advertising. Facebook for example:

You can set up a custom audience in your power editor and select people who have visited your website say in the last 30 days. You can pick the time frame but we will say 30 days in this example. Facebook will then give you your pixel or tracking code and you go to your website that you told facebook and you place that pixel in the html header section.

The you need to start telling people and sharing your website throughout facebook and facebook will gather all the different people who visit your site and save who they are. Once you have an audience of say around just 50 to 100 people you can then create a campaign in facebook ads say with a sponsor post and your ad is going to follow these people who have visited your site in the pass around on facebook and its going to cost you a lot less money. These people can be some of the best converting people to re market to.

I believe Ad-roll is another good re-targeting source apart from FB.

Add Retargeting Pixels to Redirect HTML Page on your website.
