Recommended petitions appear on the platform based on several factors. Location and language are anchoring factors, meaning that the country you’re accessing Change.org from and the language setting you’re using on the platform are the basis for what you see.

With location and language as an established base, the following factors are weighted equally to determine which petitions appear:

• Signature volume and trend: Content may be displayed based on signature volume and trend. Petitions with high signature volume within the past 24 hours are considered ‘popular’ or ‘trending.’
  • Example: ‘Trending’ petitions under ‘What’s happening on Change.org’ on the homepage; ‘Popular’ petitions on the ‘Browse’ page.
• “Category tags” or “topics”: Content may be displayed based on ‘category tags’ or ‘topics.’ Petition starters may add tags to their petition(s) by searching for existing tags or adding new tags. Only tags approved by staff are used as criteria for the recommender system.
  • Who interacted with the content: Content may be suggested for you if other people who interacted with the content also interacted with the same petitions as you.
  • Related tags/topics: If you’ve recently engaged with a certain topic on Change.org we may suggest other content that is related to that topic. For example, if you recently signed a petition about protecting wildlife, we could suggest other petitions about wildlife, natural habitats, etc.
  • Example: ‘Trending’ petitions under ‘What’s happening on Change.org’ on the homepage.
• Recent petitions: Content may be displayed based on how recently it’s been published and if it meets a minimum threshold of signatures.
  • Example: ‘Recent’ petitions on the ‘Browse’ page; ‘Most recent’ petitions on topic pages.
• Relevant keywords: Content may be displayed based on how relevant it is to keyword(s) that have been entered in the search bar and if it meets a minimum threshold of signatures.
  • Example: ‘Search petitions’ page.
