This is the poorest performing investment I've experienced in the last three years of doing business. We have a six month campaign with a customer database of 1,200 customers. We're about 1/2 into the campaign and so far we've only received 1 review.
So for every $1,000 you spend with Signpost, you can expect 1 review on google. Very poor investment. Almost no ROI at all.
I called them in hopes of ending the service but no luck.
