I have never seen a not for profit organization that the website and social media wasn’t the most important part of promoting the organization. Many nonprofits do not have a lot of money to spend, however you can’t afford to skimp on your web site and online presence! You might as well throw in the towel. I’ve see so many cases, where an NPO gets an opportunity to promote itself on television or radio, and they are not ready. What do you do on radio and television? You tell them to visit your website for more information or to donate!
Your web site is an investment in your organizations future. Do whatever necessary to secure the funds and invest in a proper web site. If you don’t another organization will, and you will be left in the dust.
