Open LinkedIn on any given day and the feed is the same handful of patterns on repeat: a green "Open to Work" frame around someone's profile photo, a post that opens with "I'm humbled and excited to announce...", a recruiter's connection request with a form-letter message, and a "trending" news module nobody asked to follow. None of it is spam in the technical sense — it's the platform working as designed — but that doesn't make it any less noise if you're just trying to read updates from people you actually follow.
LinkedIn's own feed controls ("See less like this") are slow, per-post, and reset constantly as new people post the same kind of content. A one-time keyword filter fixes the pattern instead of the individual post.
What to Filter
A handful of keyword rules cover almost everything:
Humble-brag openers
Phrases like humbled and excited or thrilled to announce catch the vast majority of the "I got a new job / promotion / certificate" post format, regardless of who's posting it.
Recruiter and hiring language
If you're not job-hunting, terms like we're hiring, open to work, and DM me your resume filter out most cold-outreach and hiring-announcement posts in one pass.
Engagement-bait formats
Posts built entirely around a hook like unpopular opinion or agree? are a recognizable template — filtering the phrase filters the format, not just one post.
Use a CSS Selector for the "Open to Work" Banner Itself
The green "Open to Work" photo frame is a visual badge, not text — a keyword rule won't touch it. This is exactly what ElementHider's point-and-click CSS selector picker is for: click the badge once on any profile photo where it appears, and the generated rule hides that specific element everywhere it recurs in your feed, without needing to know any CSS yourself.
Widen Coverage with Regexp (Supporter Pack)
Hiring and humble-brag posts use a lot of near-duplicate phrasing — "thrilled", "excited", "humbled", "proud" are functionally interchangeable openers. A single Supporter Pack regex rule like (thrilled|excited|humbled|proud) to (announce|share) catches all of those variants in one rule instead of adding four separate keywords, and keeps catching new variants as they show up.
Group Rules by Reason
If you only want the hiring-related filters active while you're between jobs (or only want the humble-brag filters on, but not hiring posts, once you start job-hunting), Groups (Supporter Pack) let you toggle each category on or off in one click instead of deleting and re-adding individual keywords.
Tip: Test Mode highlights matches without hiding them yet — a good way to confirm a new phrase like "unpopular opinion" isn't accidentally catching posts you actually wanted to read, before switching it to Hide.
The Bottom Line
LinkedIn's feed noise is a small set of repeating formats, not an infinite variety of content — which makes it a good fit for keyword filtering. A handful of phrase rules plus one CSS selector for the "Open to Work" badge clears out most of it permanently, instead of dismissing the same kind of post one at a time, forever. The same approach carries over to other feeds — see how to filter your Facebook/Instagram feed or clean up Twitter/X.
