I'm looking for ways to market to business travelers.?

There's no such thing as no-cost, but there are ways to market that are less expensive that truly traditional methods (advertising).

I'd start with pay-per-click marketing on business travel-related keywords.

Boring, huh?

Think about ways you can reach these folks where they congregate. My first pass at that would be airports, business-focused hotels, conferences, taxis (in cities where there isn't much cab traffic and most taxi travel is to/from airports), car services, online forums, through business associations who put on conferences around the country, professional associations where the job (consultants, marketers) usually entails lots of travel.

More businesses/organizations of all sort are open to opening themselves to advertising that they believe their customers will want to see. Of course, you have to offer them something in return.

Here's a few random ideas to get you started:

- Advertise on taxi receipts (you pay for the printing of the receipts, at a minimum, but also probably would have to pay the cab company)

- Outdoor advertising near airports and train stations. Doesn't have to be giant billboards. There are a lot of smaller opportunities available.

- Work out a deal with a car service that does a lot of airport transportation... perhaps you could put your logo on some small candy or snack item that they could offer their customers... mixed nuts, mints, etc. The drivers could hand them out to all their customers.

- Sponsor professional association conferences in some small way... whether buying an exhibit booth or going more guerrilla and handing out promo items outside the HQ hotel or conference center. A lot of association-type meetings gather folks from around the country... pick the right ones, they'll be frequent travelers

You won't be able (legally) to hand out stuff at an airport or in a hotel or convention center, so be sure you're careful about following rules. That said, the sponsoring association/business might not like you piggybacking on their event if you haven't paid them for the privilege.... but as long as you're on public property and not in the space they have rented, they shouldn't have much say in the matter.

Good luck!

There are no free ways to effectively market! I would suggest you place ads in magazines geared to specific industries, there are lots of them out there and they charge much less than a major periodical would.

Trade journals such as business management, engineering and Technology, office environment and eqipment, selling and merchandising and so on. These are just the tip of the iceberg and they target your market but all have limited distribution thus lower advertising rates.

You might try to link up to travel websites as an affiliate.

That's about the cheapest thing available.

If you have a legitimate business, you should invest in it with proper promotions and they cost something. Whether you use PPC, SEO for a website or tradtional methods.

EVERYONE on YA wants FREE advertising.

If it only that easy, I would be doing it as well, along with millions of others.
