Encourage sponsors and donors with a sponsors page and scrolling banners at the bottom of every page. These have links back to their respective websites. It is also a great way to say thank you to donors and supporters. You have a group of potential visitors to your website that have a high probability of actually visiting the website. These consist of the school parents, club members , or the supporters of a cause for which you are raising money. This is valuable cyber space which can be valuable for well targeted advertisers who are prepared to pay for that exposure.
