I don't guarantee results and I never will because I'm a man with integrity and that would be straight up lying. Have I scaled companies from low 6-figures to 7-figures annually? Yes. Have I doubled revenue for companies in a year? Also yes. Have I gotten solid but unremarkable results for others? Also yes. And have I worked with guys in insanely difficult markets and been the one to have the tough conversation after a few months telling them to stop paying me and stop paying Google because of what I found in the account and in their business? Yes. That's happened twice.
I can't control the market. I can't control the economy. I can't control consumer behavior. I can't control how quickly you answer the phone. I can't control your sales team's outcome. Heck, I can't even control the types of opportunities you get to a small degree. Because the people with a house cleanout and the people with a few pieces of furniture to get rid of are all largely searching the same keywords and search terms (more or less).
Let's just say for instance I work with two companies and I get them each 10 leads. One company just so happened to have 3 house cleanouts and 6 other real job requests with 1 tire kicker. The other company had 8 tire kickers and 2 real jobs but they were small. All 20 of those customers searched the same thing (for the most part). To one guy I'm a genius and to the other guy I may not know what I'm doing.
But ads are like the lottery and every conversion is a ticket. What happens with that ticket and who's on the other side, we don't know. But the companies that spend consistently and manage their ads the best will always end up ahead. Why? Because they get more opportunities, and more opportunities means more of the good ones! And most importantly, they understand the value of lifetime customer earnings and don't judge success on a month to month basis, because plenty of leads in a given month simply aren't ready to move forward yet. But with a proper follow up procedure and a strong enough website that leaves a lasting effect, those seemingly dead leads in that month come back to life in the next.
Marketing is a funny game and quite difficult to master because of how many variables are at play. Think about it. If it were so easy we'd all own every market and be stinking rich. But look around, that's seldom the case, right?
