We show elements that usually work well, with one or more real examples. You don't have to include all those elements on every page. They are just ideas so you can decide which ones fit best for your specific needs and goals.
If the page in question has enough volume of traffic and conversions, you can do A/B tests with different versions of that page to check which one gives better results.
It's interesting to request the user email in the first step (so you can maintain contact with the user later if they do not complete the entire donation process)

Images/content to share
There are certain social networks that do not allow direct sharing of URLs, only images or videos (for example, Instagram and Youtube).
A variant of this is the "ecards", which sounds a bit old-fashioned but there are still many people who search for them on Google.
In their traditional version, they are sent by email using the "ecards" system provided by the website. But the website could also give users the card in image format (to download) and then each user would decide where they want to share it.
Offer different options to receive information
Offer different options to help
At the end of each article, readers can be asked to help in different ways (works better if the help asked is related to what they just read).
Require user registration
It is a risky concept, requesting registration to access free resources. It can work well if the organization's priority is getting registrations, the resources are truly valuable and the users can understand what they get by registering.
Show a popup
A pop-up window can be shown as soon as the page is opened, after X seconds or when the user seems to be leaving the web (“exit popup”)
Promote a newsletter
It may be interesting to keep in touch with users, asking them to subscribe to the organization's newsletter
Promote a forum or social network
Promote groups or face-to-face events
Promote online courses and apps
Show donation forms
It can be put at the end of the article and/or in the middle as they do here:
Promote free downloads
It is a good hook to get the data of potential donors and then keep in touch (send them related articles, invite them to events, ask them for donations, etc.)
The captured emails can then also be used for remarketing campaigns on Facebook and other platforms.
You can focus the entire landing page on the document (brief explanation of the document + download form) or just be a complement to the main content (normal article + download form at the end of the article).
