Hi, my name's Sonny. How's it going?
You stated that your objective was to: "generate 100 Facebook leads for my home delivery bottled water company."
Number one advice:
To achieve this objective, I highly recommend using Facebook video ads.
(Everyone else will tell you to use "lead ads" right off the bat = waste of money)
(I can illustrate a proven example of using Facebook video ads (taken from an acquaintance earning, I believe, over $30K/month revenue with his Ecommerce store selling cooking utensils):
First, target Facebook interest groups related to your business with video content. In my acquaintance's case, he sent video ads teaching people how to cook recipes.
Once your video ads have received a large number of viewers who've viewed over 50% or 75% of your video, create a "lookalike audience" from them.
Finally, send product/lead ads to the lookalike audience.
(and continue to optimize the Facebook pixel as customers click through to your checkout and purchase products).
(Essentially, this above method discovers those most interested in what you're offering (via high video viewing % from video ads), cheaply, and then enables you to target people similar to the highly interested individuals who first viewed your videos (via lookalike audience) with your product/lead ads.)
There are, obviously, far more steps (which I'm unable to fit inside the character limit).
I look forward to discussing further, and helping you gain more customers.
Regards,
Sonny
