How to Monitor Linkedin Comments and Likes for Sales Signals (Not Only Posts)

A prospect posting once a month is easy to miss. The same person commenting on a competitor thread, or liking a category post that matches your ICP, often shows intent sooner. Native Linkedin Follow mainly surfaces posts, filters hard, and is not anonymous. Many activity monitors stop at posts too.

We build MultiFollow, so here is the honest shape. MultiFollow is an anonymous Linkedin and X (Twitter) account activity watchlist. You paste person (and company) URLs, choose posts, comments, and (on Linkedin people) likes, and we fire when those accounts move. This how-to is the comments-and-likes path for sales signals. Company pages stay posts-only. That limit is real, and we treat it as a product fact, not a slogan.

For company pages plus execs as a stack, see How to monitor competitor Linkedin company pages and executives. For cutting comment noise with include/exclude lists, see How to filter Linkedin and X watchlist alerts with keywords.

MultiFollow real-time sales signal feed

Job to be done

Get alerted when a named prospect or champion engages in public Linkedin activity that is not a full post: a comment on a competitor or buyer thread, or a like on content that shows category interest, so you can reach out while the context is still fresh.

What MultiFollow tracks per account type

Tracker type	URL format	Posts	Comments	Likes
Linkedin person	`https://www.linkedin.com/in/{username}/`	Yes	Yes	Yes
Linkedin company page	`https://www.linkedin.com/company/{name}/`	Yes	No	No
Linkedin showcase page	`https://www.linkedin.com/showcase/{name}/`	Yes	No	No
X (Twitter)	`https://x.com/{username}`	Yes (posts + replies)	Replies yes	No (private since 2024)

Honest limits before you enable every checkbox:

Comments and likes for sales signals mean Linkedin person trackers. Company and showcase pages do not expose comments or likes through MultiFollow.
Keyword include/exclude filters apply to posts and comments text only. Likes have no text, so keywords cannot filter them.
MultiFollow does not track job changes. If that is the job, use a different tool.
Monitoring is anonymous. We do not follow or connect on your behalf. They are not notified.
Refresh is per second. Notifications usually land within a couple of seconds, up to about a minute under congestion.
This is a named-account watchlist, not open keyword listening across the web. For that sibling job, use KWatch.io.

Field reference: Trackers docs.

When comments are the signal vs when likes are

Comments (usually the stronger sales signal)

Comments carry text. You can read intent, and you can filter with keywords.

Useful patterns:

Prospect comments on a competitor launch, pricing, or migration thread.
Champion drops "looking for", "evaluating", "budget", "RFP", or a category pain in a public reply.
Target account AE or ops lead asks a practical question on a vendor or peer post.

Start with posts + comments for most people trackers. Add keyword includes for the phrases that actually mean buying intent in your market.

Likes (weaker, noisier, still useful in a short list)

Likes have no body text. You only know that they reacted, not why. They flood Slack if you enable them on a large list.

Useful patterns (narrow VIP list only):

CEO or founder likes a category thought-leadership post you care about.
Champion likes your customer's case study or a competitor takedown post.
Buying committee member likes hiring or "we are scaling X" content that correlates with your motion.

Be honest with yourself: likes are secondary. Turn them on for 3-10 VIP people after the comment feed is clean, not for everyone on day one.

Setup: catch comments and likes without drowning

Step 1. Shortlist people (not company pages)

Comments and likes live on person trackers.

1. Sign in at dash.multifollow.io. Free does not need a card.
2. Build a short people list: open opportunities, champions, target AEs, and 2-5 competitor execs who engage publicly.
3. Paste full Linkedin person URLs: https://www.linkedin.com/in/{username}/.
4. Keep company pages on a separate list for official posts only. Do not expect company comments or likes.

Tip: if you already have a company + exec stack, reuse the person rows. This post is about flipping the right activity flags on those people.

Step 2. Set activity flags per job

On each Linkedin person tracker:

Job	Posts	Comments	Likes
Buying-intent language	On	On	Off
Competitor-thread engagement	On	On	Off at first
VIP champion warmth	On	On	On (short list only)
Company narrative only	Use a company tracker	N/A	N/A

Default recommendation: posts + comments on, likes off, until Tuesday's inbox stays readable.

Step 3. Keyword-filter comments (leave likes alone)

Keywords only score text-bearing events.

1. On the tracker, open Included Keywords and Excluded Keywords (comma-separated, max 10 each, 2-200 characters).
2. Example include for outbound: pricing, RFP, budget, evaluating, demo, a competitor name you actually see in threads.
3. Example exclude: webinar, congrats, newsletter, podcast.
4. Leave include empty if you want every comment (still subject to exclude).
5. Remember: likes ignore keywords. If likes are noisy, disable likes on that tracker.

Step 4. Choose delivery, then prove one real comment

Email: Free and Essential (and every higher plan). Fine for a solo pilot.
Slack incoming webhook and API webhooks: Business and above. Pipe into Slack, Clay, n8n, Zapier, Make, or your CRM.
Routing walkthrough: Route MultiFollow alerts to Slack, Clay, n8n, or Zapier. Ready-made Clay paths: Clay templates for sales signals.

Verification checklist:

1. Save one Linkedin person tracker with posts + comments, likes off, and a tight include list.
2. Wait for a real matching comment (or loosen one keyword after a quiet day).
3. Confirm the alert shows a comment, not only posts.
4. Optionally enable likes on that one VIP tracker and watch volume for a week before rolling likes out.

Common mistakes

1. Enabling likes on everyone day one. Likes cannot be keyword-filtered. Start comments-first.
2. Expecting comments or likes on company pages. Company and showcase trackers are posts only. Track people for engagement.
3. Expecting keyword filters to quiet likes. They cannot. Turn likes off instead.
4. Expecting job-change alerts. MultiFollow tracks posts, comments, and Linkedin person likes (plus X posts/replies). Not title changes.
5. Mixing company narrative and person engagement in one Slack channel. Split delivery (or per-tracker webhooks on Business+) so launch posts do not bury a prospect comment.

A practical people stack (example)

For one open opportunity:

Person	Activities	Include keywords	Delivery
Champion (Linkedin person)	Posts + comments (likes on)	`budget`, `RFP`, `evaluating`, your category stem	Slack `#signals-outbound` or email while piloting
Economic buyer	Posts + comments (likes off)	`pricing`, `vendor`, `migration`	Same channel
Competitor exec (context)	Posts + comments (likes off)	your product category, `launch`, `pricing`	`#battles` or a separate Clay table

Act from Slack, Clay, or email. MultiFollow is the trigger, not the send button. Reply on the thread, then InMail or email from whatever you already use.

Frequently asked questions

Do you track Linkedin comments and likes on company pages?

No. Company and showcase pages: posts only. For comments and likes, track Linkedin person URLs.

Can keyword filters apply to likes?

No. Likes have no text. Keywords only filter posts and comments. Disable likes on noisy trackers.

Will prospects know I am watching their comments and likes?

No. MultiFollow does not follow or connect on your behalf. Monitoring is anonymous.

Do you track likes on X?

No. X likes have been private since 2024. On X we track posts and replies.

Is this the same as open keyword listening across Linkedin?

Which plan do I need for Slack when a prospect comments?

Email works on Free and Essential. Slack and API webhooks need Business or above.

Do you track job changes?

No. MultiFollow is Linkedin/X activity (posts, comments, Linkedin person likes, X posts/replies), not employment-change detection.

Get started

Create a free account, paste one prospect person URL, enable posts + comments with likes off, and prove you get a real comment alert before you widen the list. When the team needs the same signal in Slack or Clay, move to Business and paste the webhook.
