With the Duplicate filter, you can ensure that you only get notified about a certain story, post or link once. This is useful if you follow a lot of feeds that might report on the same things.
This feature is available for the Professional and Enterprise plans. Please see our pricing page to see what plan suits your needs.
How it works
The Duplicate filter works by not notifying you about a story if it has the same URL or title as a story you have already been notified about.
To create the Duplicate filter, you go to the Rules tab and create a Rule where you select the “Duplicate filter” as type of Rule. You then select the feeds you want to apply the Rule to, and the filter will be applied to all posts from those feeds.
Creating a rule
- Go to Rules and press “Create new rule”.
- Select the sources you want to apply the Rule to.
- Select “Duplicate filter” as the type of Rule.
- Choose the settings for the Rule.
- Save and you’re done!
Duplicate window
This setting allows you to specify how long a story is considered a duplicate. The options are 7, 14 or 30 days. This means that if the same story is posted after 7, 14 or 30 days, you will be notified about it again.
Consider unique by
You can choose to filter out stories based on their URL or title. We try our best to normalise the URL and title. For example the title “This is a story” and “This Is A Story!” will be considered the same.
We also remove any tracking parameters from the URL, so that `https://example.com?utm_source=twitter` and `https://example.com` will be considered the same.
Duplicate pool
Each Rule you create with a Duplicate filter operates independently. This means each Rule has its own ‘pool’ of duplicates, based on the feeds you’ve chosen for that particular Rule.
Examples
If you create one Rule with feed A and B:
If a post is posted in feed A, and then later in feed B, you will not be notified about the story in feed B. You won’t see the story in Feed B at all, since it has been filtered out. Feed A and feed B have the same ‘Duplicate pool’.
If you create one Rule with feed A, and another Rule with feed B:
If a post is posted in feed A, and then later in feed B, you will still be notified about the post in feed B. You will get notifications from both feeds. Feed A and feed B have different ‘Duplicate pools’.
Limitations
If you change the parameters of a Duplicate filter, it won’t retroactively update the posts that have already been filtered out.
