I don't think Sponsorships in general add to the bottom line of most business's initially or as soon as they would like. With the exception of Nascar maybe. Let me clarify. Sponsorship is a tool for 'Promotion' It is another advertising outlet for firms. What sponsorship does, is create 'Opportunities' 'Impressions' for the sponsor.
Which, does not necessarly turn into sales. What it does do, is creat 'brand' awareness, and then hopefully when the fan or consumer goes to buy a product he or she remembers the logo, or banner a sponsored team was flying. These are 'potential' sales. Trying to 'sell' sponsorship as direct ROI dollars to a prospective sponsor is futile. Any serious marketing manager will know you are making claims you cannot deliver. Perhaps you could create sales through POS and POP marketing campaigns. But then there are vendor fee's, ect... One of the keys is to know what the firms target is. If you are not offering something that is directed towards the firms target audience, you can forget it. Also, knowing specifically who to send your proposal to is quite important. If you do not have a contact name and some type of previous contact, such as email, letter or phone call you will not be able to get the person you are trying to reach. If it winds up at the general mail bin, and it does not have a specific department and title it will most likely wind up in the 'round' folder. Providing details to the prospective sponsor is vital. Demographics are something that a firm is going to want to see. Past exposure you may have had. One thing that is a detriment to our domestic sport except the AMA is not having TV coverage. IMO, This is probably the biggest single road block for not getting sponsorship. TV Impressions are worth big bucks to firms. That is one of the ways Sponsors measure their ROI. Someone from the firm, usually from marketing will watch the telecast with pen and paper and stopwatch. They will count how many times their logo is on screen and for how long. Then they translate that into advertising costs and time slot, network, ect...to come up with a value.
So, TV is critical. Even if you are not a front runner.
Getting a sponsors logo/name on screen for 10 seconds is valuable. A 30 second spot may cost them 5k, 10k, or more. It depends obviously on the network, the time, and the ratings. But this is where it makes the most sense for a prospective sponsor to get involved. Just relying on Print, Web, and at track signage impressions are not enough for big firms. It is very frustrating for the racer, and team owner. Sponsorship is not easy to come by and not easy to maintain. It takes ALOT of hard work. Maybe more time than you would spend preping, competing, and travling to the races. One thing that is positive is that FUSA is actually willing to assist racers now. I think that is a major step in the right direction. That is what CART and NASCAR and Grand Am do. They solicit sponsors for their competing teams. It helps the series grow, and makes them look even more professional. It makes good economic sense for the sanctioning body to do this. Most racers do not have the resources to go out and hunt sponsors down, like I said it can be a full time job.
