I was doing PPC on my own from ages 16-31 before hiring Andy 5 years ago, and we've been using him ever since. He's really a specialist and knows way more than I ever could. We hired him when we were at $25k/mo in revenue and we've stuck with him the entire time we've grown to $150k/mo. He is comfortable pushing back, but still stays flexible to understand nuances within our business when we think something doesn't make sense for us. When campaigns are stalling out he's making suggestions for things to try. Sometimes they're really obvious but we just didn't think about it. He also reviews the keywords each month and blocks the ones that are wasting our money. He understands our business.
