I believe the best way to promote my website is to get thousands of REAL people to share it on their Facebook timelines. Obviously, if that trend continues, my website could go viral. What do you think is the best way to get started? P.S. I tried websites like AddMeFast in the past and didn't get any results because many of those people have fake profiles.
If you post update about any emergency message which is urgently needed for everyone then may have possibility to get shared quickly. Like you could post weather forecast but keep in mind the forecast have to be true or have to be supplied from weather department. Think about a situation like if weather forecast department announce any urgent cyclone or storm message and at that time if you post this and tell other to share to save other people. Then there could be great possibility to get huge shares.
I like to hold contests. I'll have a product that I will give away to a lucky winner. To enter the contest they have to share a post and like a page. Works very well.
My idea is by influencer marketing in which where you get in touch with users and do your pitch for an exchange of links or share =) works well for me.
My preferred method to get share on a post is just to boost the post in the Ad Manager. There you can target your audience and have the people you wish to share the post, if it has sharing value of course. You can boost post at a very low cost.
