I prefer to watch what people actually do, rather than listen to what they say. You'll be surprised how often those who teach certain things don't follow their advice themselves.
Giving out something for free, i.e. a report, an ebook, free stuff, to get people hooked onto your list is THE primary method of what all top list builders do. Look up any big names in any niche and then see how they do it...
No - it's really not, lol. You're obviously one of the listeners, not watchers.
It's not 2007, e-garbage is e-garbage because everyone can google whatever you're offering and it'll literally be there for them in a compiled, neat source - because it's not 2007 and your whole "well the googles is messy and i am offering you nice awesome info you dont have to googles 30mins for" mindset is as outdated as offering freebie seekers that are so stupid they can't Google for this information, and hope you'll be the one to relieve them of their cash.
Here's a protip "smart people" won't share with you. This is very basic, but so applicable to millions of niches that it can't die as a concept + putting spins on it is easy for better conversion. I know it'll fly over your head and you'll rant about something irrelevant, but I'm sure it'll help someone else reading this. Since MikeAus has his casestudy public - I figure using it as a conceptual example is cool.
You take your niche crowd, you find cheap, almost free-level shit - and you offer it as a freebie out of a whatever stupid story/promotion/any decent angle you can spin up. So for MikeAus - since he has his Harry Potter store - if he was looking for cheap CUSTOMER lead gen, he could take some harry potter necklace/keychain/mass appeal trinket for $.50-$1.00 - and create a product page offering it FREE - out of the goodness of his heart in some angle form. The better the angle is - the more the MAIN fact that he's charging $2.95 shipping for this freebie becomes a very minor detail - that you wouldn't have noticed unless I mentioned it - and have been calling him "dumb becuz hes spending monies on gaiz who want free stufz".
But that $2.95 allows him to:
a. cover cost of the MUCH MORE VALUABLE FREEBIE than your piece of shit ebook.
b. have $2 for Instagram/FB ad lead gen to get another 1-2 converts.
c. he's not getting Indians opting in for your free crap because they optin to free everything - every "optin" is not only a buyer email of a person showed they have strong interest in harry potter, enough to get a "free" keychain, but that they have a CC they're will to pull out and use, cuz they just did to pay the shipping.
Like I said - this is basic FREE+shipping, if you spin a basic angle on it - you can clean up pretty hard in tons of niches while building a big email list of people who'll buy this crap. Hell, even if your only retort is - "yah but they only spent $3, thats not a rael buyer" - a volume growth of this list x offering them the exact same free+shipping offer on other niche trinkets which can be found by the 1000s twice a month - some great cash each time, with the ad costs of having to acquire them now saved = X more return after their initial "buyer optin".
Hope I blew your mind, Blackman. If this didn't register, there's still no hope for you after 8 or so years. At least someone else might enjoy this and give it a run.
