Liking is one click; the more interesting work is reporting on engagement and using the data.
- Click Like on a post or comment
The Like button appears under every Chatter post and comment. Click to like; click again to unlike.
- View the liked-by list
Click the LikeCount number on a post to see who liked it. The list shows every user; useful for community managers.
- Query FeedLike for engagement reports
Build SOQL or report-type filters on FeedLike to surface top-liked posts, top-liked posters, and per-user like activity.
- Track Like trends per user
Combine FeedLike with FeedItem to surface a per-user engagement profile. High likes received indicates strong content; high likes given indicates active engagement.
- Plan for Slack reactions if migrating
Slack''s emoji reactions replace Like. Engagement reports will need to switch from FeedLike to Slack-side analytics during a migration.
Gotchas
- One like per user per item. The FeedLike object enforces uniqueness; integrations attempting to insert duplicates fail.
- Likes contribute to Chatter Influence. Engagement-driven feedback loops mean popular posters accumulate more Influence faster.
- Salesforce strategic direction is Slack, not Chatter. Customer-facing engagement programs should plan for the eventual platform migration.
- Likes are public to anyone with feed access. Users who do not want their likes visible should be aware before clicking.
