The amount of options is amazing, everything from blog submission via Facebook ads or Google Adwords campaigns to content marketing for SEO purposes can be accomplished in less than 30 minutes once I have provided all my details through their form system. Their customer service support could use some work- they are very helpful but sometimes it feels like there's an initial delay before answering questions which isn't ideal when running a business! There really aren’t any downsides as such, if anything this seems good because there will always be new ways we haven't thought about that help us grow our reach. We've seen great results already so would highly recommend using them!
