I've had a rather successful month this month, and the root of my success is merely activity. The method I have been using is making calls and setting face-to-face appointments. It doesn't matter which method you choose to employ. If you make enough phone calls, you will be successful. If you go into enough businesses, you will be successful. If you send out enough emails and/or snail mail, you will be successful. Granted, I do believe certain methods work best for certain people, but there is no shortcut around good solid work.
Not bashing those that have released WSO's on offline methods, because many of them have some fantastic techniques, but the reality of this business is getting out there and doing it. The more appointments you go on, the more calls you make, the better you will get at this. The easier it will become to ascertain what makes a good lead and what doesn't. I've led several sales teams throughout my career, and the ones that were successful, typically had the least product and sales training. The salespeople (if I even want to call them that) that wanted to know everything about the product, the approach, needed a script, needed business cards to printed, etc. before going out, were almost always the ones that failed. And they typically had an excuse for their failure as well. The ones that went out with basic product knowledge with the intent to help someone succeeded. Product/sales knowledge was secondary to the desire to be successful and help their potential clients.
So, the moral of this post is... go pick up the phone, go walk in and talk to some business owners, mail out some letters... do SOMETHING! Activity breeds success! You don't have to have a flashy website, business cards, or know exactly how to handle every potential objection. I always hated hearing this before I got into sales management, but sales is truly a numbers game. You could tie a note that says, "Do you want to buy SEO services, call 555-5555" to a monkey and send it in to see business owners... At some point, one of the business owners would buy (In fact... I should release a WSO on this method... :p).
Instead of sitting at your computer reading, thinking, dreaming about making money... Get out there and do it. Sure, you'll suck at the beginning, but as you hone your pitch and learn how to handle objections effectively, your skills will improve and you'll begin to close some business. I would venture to say that you'll close more going out and messing up than you will sitting at home thinking about becoming a successful offline consultant and trying to figure out that elusive "magic bullet" to success.
I said at the beginning of this post that there is no "magic bullet", but I've just given it to you! Get out there and make some magic happen people!
