Hello!
I'm a certified Google Adwords Partner in Canada.
From my experience, most marketing companies hire new college graduates who don’t align their marketing strategy with the situation of the company, such as cashflow, return on investments etc. and that’s why they usually don’t produce results. For instance, the way to start a budget restrained campaign is radically different from starting a traffic restrained campaign. Anyone can build a campaign in 2-3 hours, but few of the campaigns end up with being profitable. If you wish, I’d be glad to talk with you to learn more about your company, and see how we can build a strategy that fits your budget, and maximize the profit.
For Adwords, the initial setup process is a very standard procedure. However, it’s the continuous process of monitoring and refinement making the difference. If you are spending $10,000 a year in Adwords, the difference between a well managed campaign with 300-400% ROI, and a bad campaign that loses your investment, is likely to determine whether your company can be profitable or not. That’s why I’d highly recommend you to hire great people working for your paid ads, rather than finding a cheap agency that don’t (or can’t afford to) put real effort in your campaigns.
