I spent just over $650 on Facebook Boosts.
This is far better return than SEO.
Search Engine Optimization is not a marketing. Only google can control how they rank the site unless they are being paid for. Instead of paying money to someone who know how to make your site rank higher, use the same money to advertise.
They tell you organic listing is better than paid listing. Bull Shit.
When you search Google, do you intentionally avoid advertisers' links just because they are advertisements. No, you click based on what it says.
I have placed an ad. on Facebook. I get over 100 clicks to the sites in mater of weeks. Where as my organic post has 0 click though. Advertisement works. Just don't pay middleman.
