Advanced Options are available on Website and Social Account Feeds. NOTE: each feed type has its own set of Advanced Options; every filter is not available.
To view a feed's Advanced Options, click on the down arrow in the bottom right corner of your feed.
It will expand, and, depending on the feed, you will see the following options. These options are specific to a RSS Feed.
Post message configuration: add a hashtag or word/phrase to the beginning (in the prefix field) or end (in the suffix field) of the post text coming from a RSS or GA feed.
Allow links to be posted more than once: it will default to "No - only post one time" but you have the options for links to be posted not more than twice, or not more than once daily, weekly or monthly.
RSS item uniqueness rule: do not change from the default unless your CMS changes the URL when there is a change in the headline after a story is updated.
Filters: select from a URL or category and a conditional to allow or not allow specific content to be published. To add a new filter, click the blue "Add Filter" button. To remove a filter, click the trash icon on the right of the filter.
Social Account Feeds have an Advanced Option that allows you to specify a content type to be published with the feed.
Allowed content types: select from link, status, photo or video.
To ensure any Advanced Options are applied to your feed, don't forget to click the blue "Save" button when finished.
