As thoroughly explained by Search Engine Land’s Greg Finn, you shouldn’t use services that claim to purchase likes and, most recently, +1s in bulk. This is not the solution for a bigger SEO problem on your site, nor should it be used to make your site look popular. If your audience is non-relevant, “your EdgeRank will slip,” and what’s more, you’ll look like a jerk.
Our solution? Hire an SEO team (I know of this great one called Visiture). It will take longer to gain fans, likes and +1s, but in the end, they will be a quality audience and worth a lot more to you than a measly $115.
And if you’re still not convinced, check out Google’s Quality Guidelines to get your moral compass pointing North.
