Below are a list of best practices for designing non profit websites followed by some examples of non profit websites that are getting things right.

1. Make Your Site Donor-Friendly

Donations are a necessary thing for every non profit organization out there. Your website can be a great place to solicit donations, especially from new donors. It can also make it easier for recurring donors to make additional donations. In either case, you want it to be a simple and straight-forward process for people to give you money.
2. Make Your Site Media-Friendly

Getting media attention can have a huge impact on a non profit organization. Whether the media attention brings in more donations directly or simply raises the profile of the organization, getting attention from journalists, bloggers, and anyone else with an audience is important.

Make it easy for journalists to find information about your organization. Include profiles of your board of directors, founder(s), and other key personnel. Make sure you include contact information (email and phone) for each of these key people. Have a downloadable media kit that includes everything your print media kit does.

3. Make Your Site Volunteer-Friendly

Make it easy for visitors to your site to find information on how they can get involved. There are plenty of people out there who might not have the money to make a donation but are still passionate about what your organization is doing.
4. Make Sure Your Organization’s Purpose is Immediately Apparent

How many times have you gone to a website and not had a clue what the site was about? This happens all too often. Designers and clients often take for granted what visitors to their site will already know about their organization.

But considering how much information is pushed in bite-size pieces on sites like Twitter and Facebook, there’s no telling how much or how little visitors will know. With some organizations it’s easy enough to figure out what the organization is about just by its name, but for others it’s not so easy.

5. Make Sure Your Content Takes Center Stage

Design on any site should be transparent, and especially so on non profit sites. That’s not to say your site can’t have an interesting design, just that the design should revolve around your content and your mission, not the other way around. Take into account the types of information you’ll be providing on the site and the formats that will be used.

6. Make Sure Your Website is Consistent with Your Other Promotional Materials

Your logo should use the same logo and colors as your other promotional materials. Maintaining a consistent brand throughout your organization greatly increases your chances of being recognized in passing. Your website doesn’t have to (and probably shouldn’t) match your print promotional materials exactly, but echoing the look and feel of those materials increases brand identity.

7. Know Your Site’s Purpose Up Front

The leaders of your organization (or whoever is in charge of the organization’s website) should make a list of what the goals for the site are before starting the design process. Is the site primarily to allow existing members to stay updated? Is it to solicit donations? Is it to get new volunteers or members? Is it to raise awareness in general?

8. Include a News Section or Blog

Including a blog or news section has a couple of big advantages for non profit sites. First, it gives people a reason to come back to your site. If you offer news about your organization and your cause, people who are interested in either will come back on a regular basis (or subscribe via RSS). This keeps your site visible and makes it more likely they’ll become more involved in the future (or stay involved if they are already).

Citra yang dihasilkan direkam datanya bersifat kontinue harus dirubah dahulu menjadi citra digital dengan konversi sehingga dikenal komputer.

Proses tersebut disebut digitasi, yaitu membuat kisi-kisi arah horizontal dan vertical sehingga terbentuk array 2 dimensi.
