1.Trade shows – These are the number one place to hand out any promotional item, but promotional keyrings can really stand out if you have a nice design. Most of your competitors will probably be focusing on promotional pens and other promo items, so a key ring can set you apart from the competition and at least you won't get forgotten immediately.

2.Within your business – Although the people visiting your business are already aware of your brand, it doesn't hurt to have promo keyrings sitting in reception or retail areas. Plus getting in home placement might just be worth it, depending on the industry you are in.

3.Malls and other stores that might get customers interested in your business offerings are good, although you have to do a bit more maneuvering to get yourself set up in those. Try to get some face to face time with the owners of the store and see if you can't set out a basket of promotional keyrings.

4.Popular vacation spots – If your town is a tourist trap, make sure to have your promotional keyrings in strategic areas. This will help your brand spread to other parts of the country, or perhaps even the world.

5.Local Fairs and Events – While you might not have a business that really markets to your community, it is good to make an appearance at local events. You can gain good will from the community, as well as warming up the general populous towards your business. This is great promotion for gaining quality employees – just show that you really care about the area your business is located in, even if it's just with some promotional give aways.

6.Current Clients and Business Partners – These guys are obviously already pulled in by your branding and business, but giving them free stuff will always go over well.

7.Consumer Shows – If your business can benefit from consumer marketing, then you need to make sure that you have a presence at any b2c events. This will let you interact directly with your market base, and allow them to spread word of mouth marketing about the great people at your business. As you know, word of mouth marketing is absolutely amazing for bringing in new business, so this is a golden opportunity for you.

8.Career Fairs – If you're on a hiring spree, a career fair might just be the place for you to promote yourself with keyrings. You can also hit job centers if you have one in your local area.

These are just the tip of the iceberg – you should have many other opportunities to hand out promotional keyrings, and since they're small and distinctive compared to business cards, you should certainly make an impact. Just make sure to leverage all promo opportunities that come your way to build your brand.
