You can add content to a site using its content library. Items added to the content library are automatically added to the content group, which is a view access group. Items belonging to this group can be used by core team members when designing the site's layout and are visible in search to those with whom the item is shared (such as the public or the organization).
Note:
Content can only be edited by the item's owner (the person who originally created the item or uploaded it). To share an item with the core team so that team members can make edits to it, follow the steps provided in Give edit access.
Upload content with a URL
You can upload content using a file from your computer or a URL.

Add existing items
You can add content that other organization members have created.
Note:
It's suggested that you talk with the item's owner before sharing it with a larger audience. Also consider that unless the item is yours or shared with your core team, or you have administrative privileges, you cannot change the sharing settings of an item. This means that private items (items shared just with you, the core team, or the organization) that are shared to your site will not be visible to people with whom the item is not shared.

- Click the second drop-down menu in the edit navigation bar.

- Click the Add Existing Content button.
- Filter the list of existing content and click to select the individual items that you want to add.

The item is shared with the site's content group.
Use the Groups Manager to add groups
You can optionally add groups of items to import bulk content to a site's content library. For example, you can add groups, such as open data groups, department-specific groups, or content groups from other sites.
Some organizations may find it useful to add additional groups of items that are relevant to a site, such as department-specific content or content groups from other sites. To add a group to a site, the group must either be owned by you or shared with the organization.
