This preset helps users look for websites of organizations, charities, institutions or initiatives that accept donations or sponsorships. Some of the parameters, i.e. operator/footprint combinations, are targeting pages listing the donors, while others go after donation forms and guidelines.

intext:"ways to give" OR intext:"support our organization" OR intext:"support our cause" OR intext:"support our charity"
inurl:donate intitle:"donate our charity"
