A main goal of any franchise corporation is to sell franchises. I think it's easier than ever for a franchise to build their brand's reputation over the internet. For example, if you owned a fast food franchise, you could search on Goolge for blogs that are industry related. Get in on the conversations and contribute. Provide valuable feedback on the topics being discussed. Ensure to insert a backlink to your website or blog whenever possible.
Another suggestion I have for franchisors selling franchises is to contribute to community sites sucha as LinkedIn and facebook. Join and start your own groups within communities. You'll soon find that it's not too difficult to connect with people that are interested in similar Franchising topic(s).
I have started a Squidoo lense that is designed to provide information to Franchises on how they can grow rapidly using social media and web 2.0 technologies. For more information, you can visit the lens here: Franchise Marketing Ideas
