I think the object of this part is to create a list of people's emails so that you might have a database of people to sell things to. The easiest way to create this email list is to offer them something free. That way people will be willing to sign up for your free whatever it is that you want to give them. Once you create a little form for them to put their name and email into, then you give them the free thing. It could be something they download, or it could be something tangible, such as something physical you send in the mail. It would be more expensive to do that, but the way you get around that is to do a raffle. If you offer something really good, something that costs money, like a gem or a ring or something similar, you could raffle it and still, people would be willing to give you their email just for the act of getting in on the opportunity to win the ring or the gem or whatever it is you would like to raffle. It could be a "Fidget Spinner." It could be anything.
What is the best place to find out a lot of people that are interested in your niche hanging out together? A niche forum of course! Join a niche forum and not only you'll interact with people possibly interested in signing up to your list, but you'll also be able to get to know them better and find out more information about their needs and problems. Great place to get ideas, isn't it?
Considered a form of interruption marketing, interstitials are any page or pop-up that forms a roadblock to users’ path to content, either by displaying over the content or interrupting it. Users have no choice but to interact with the display before they can proceed. Forbes was a classic example of the “before” interstitial (also known as a “prestitial”).
Some ad platforms will ask more of your landing pages than others, when running ads. For example, AdWords is much stricter, when compared to Facebook. AdWords typically requires that you do not have a ‘thin,’ site that is designed solely to collect leads. Because of this it might be a good idea to focus on using Facebook or Twitter, to begin with.
