I've been using Google Ads for a long time but I've never really seen results. I didn't realize that it would take so much work and that this was a task that was better being outsourced to a professional agency. I didn't really know how to find a good agency, though, until a friend of mine recommended Metric Labs. It's clear from their website that they're the best people for the job.
As a specialized AdWords agency, they'll take control of this task. That means I'd be free to focus on other aspects of my business. They're a results-based company so you get real, quantifiable evidence on how well they're performing.
