It got me over 3000 people to like my page within a time span of 10-12 hours..
I won't mention my Facebook page here in order to protect my scarcely tapped niche but lets take an example... lets say I have a website where I sell perfumes to residents of my town/city..... I have a budget of $50 a day to spend in advertising and marketing... Instead of putting it all on ads, I decided to give out a $40 cologne for free... so i made an image in MS Paint stating, " Like and Share this page and get a chance to win XYZ perfume"... I also mentioned that the random winner will be selected in 24 hours.... I put in $5 as my Facebook ad budget and allocated a CPM of $0.05....
Thats all I did.... Within 10 hours my page had over 3000 likes and that post was shared over 4000 times!
Now... the down side of this method....
1- I got MANY people calling me to check whether this competition was for real ..
2- When I announced the winner...approx 50 people congratulated the winner in the comments section.. whereas over a 100 started with hate messages stating im a fake :/ .... I decided to post a photo of the winner with the item... some of the people who were criticizing stopped whereas the rest started claiming " He gave away the gift to a friend'
3- When I make posts about my products and special offers on my sites, I hardly get any response from these Facebook fans I got through the competition.. I realized that is because I targeted the wrong audience... these people fanned my page just to get a freebie.. they were/are not interested in buying anything....
Conclusion: this trick got me a lot of fans in NO time however it was a complete failure to my cause because the people I got were the exact opposite of what I want... however I think that this method might work for some... If you try it and it works for you, do let me know.... If you notice anything wrong I did and something i could do differently, do let me know
