Finding a good SEO link‑building community these days is quite challenging, especially the one that matches your needs.

I know this because I've joined many of them and found that many of groups are spammy or slowly dying out.

That said, I did come across some that are quite good!

In this post you’ll get my five favorites, the vetting steps I used, and who each group is perfect for.

Let’s dive in!

Methodology: How I Picked the Communities

Before naming winners, I needed proof they worked.


Here’s the process I followed to pick out the best one:

1. Google search - Ran queries like “link building Slack community.” Collected the first 100 results and removed spam or dead links.

2. Join and verify -  Joined every remaining group to confirm each workspace was real and accessible.

3. Activity check - Watched posts of the last two monhts. Kept only communities with daily, genuine discussions.

4. Member count - Logged the live member total shown in Slack. Very small or inactive groups were dropped.

5. Background screening - Noted entry rules such as company email or LinkedIn. Groups that vet new members scored higher.

TL;DR: My Top 5 Slack Link‑Building Communities That Are Worth a Visit


If you’re in a hurry, here’s a brief look at the best Slack link building communities:

  • saaslinkbuilder community – best for SaaS link builders
  • Digital Olympus – best for digital PR outreach
  • Traffic Think Tank – best paid community
  • Backlink Masterminds – best for guest posting collaborations
  • Ranktracker – biggest slack group

A Slack link‑building community is a shared workspace on Slack.

People meet there to discuss link building, trade ideas, and ask questions.

Typical activities include:

  • Posting link exchange offers
  • Share ideas about link building
  • Ask questions and participate in link building related discussions


It is a live, always‑on chat room where every member cares about building awesome backlinks.

What Are Different Types of Communities?


💬 Public communities - Free to join through a shareable link. Anyone can hop in, so you’ll meet beginners and pros alike.

💬 Private communities - Entry needs organizer approval. Often ask for a short form or proof you work in SEO.

💬 Paid communities - Charge a one‑time or monthly fee. Offer gated resources, expert sessions, and tighter moderation.

💬 Invite‑only communities - You join through a member referral. Keeps the network small, trusted, and highly focused.
