They want to read what's NEW
If you have news to tell but don’t have a news page, you’re missing an effective tool… please add one ASAP… it will soon become one of your most-viewed pages. It’s one of the key things people want to see. But if you are generally unable to come up with news stories, I suggest you actually DON’T have a news page, as readers (and potential donors) will be put off by the old news and lack of activity.
If you’re not sure, try this. In the short-term, you can create a free blog (e.g. blogger.com), make sure it has a similar corporate look to your website, and populate it with your news. Ensure there are obvious links to and from your website, and add a link to the main website from most of your posts too, as that’s where your donations will be made.
