Link Building Communities: 12 Link Exchange Groups Compared, and What Publishers Say About Swaps

Every list of link building communities is written by an agency that runs one of them, so the list is the sales page. This one is not. MentionAgent does outreach, not swaps, and the reason to read this page is the second half: what 2,511 publishers actually said when a link exchange came up in a real outreach thread, which is the closest thing to knowing what happens inside these groups before you join one.

What a link exchange community is

A link exchange community is a group where people who run websites post two things: the pages they can give a link from, and the pages they want a link to. Somebody with a matching pair replies, the two agree on anchors and pages, and each adds the other's link. That is the whole mechanism. Everything else, the application form, the channels, the weekly matching thread, the DR floor, is a way of keeping the group from filling up with people who have nothing worth linking from.

There are three shapes, and they behave differently enough that it is worth naming them before the list.

Vetted Slack groups. Free or cheap, invite-only, a few hundred to a few thousand members, run by one agency or one founder. Link Exchange Crew, Get Pro Links, Backlink Masterminds and Brainspin's #backlinks are this shape. The swap channel is one of several, and the group's reputation depends on keeping sellers of private blog networks out.

Open marketplaces. Facebook and LinkedIn groups with five-figure member counts and no application. The word "exchange" is in the group name, but their own listings describe guest posts, niche edits, link services and PBN inventory before they describe swaps. r/linkbuilding sits here too, with a moderation layer.

Matched platforms. The same idea with software doing the pairing, usually on a credit system. Those are a separate market with their own pricing and rules, and we compared the seven on Google's first page in backlink exchange platforms. This page is about the human groups.

What all three have in common is the population. Everyone in the room wants links. That is a different crowd from the one you reach with link outreach, where the publisher had no plan to link to anybody until the email arrived, and it shapes what a link from the group is worth. We judge a link on whether it sends readers, which is the argument in relevant backlinks. More on that in the data section.

The twelve, compared

Checked on 16 September 2026 on each community's own site where it has one. Where the community does not publish a size, the figure comes from a dated third-party listing and says so. "Could not check" means the site did not respond, not that the group is dead.

Two cautions on the numbers. Member counts for the same group differ by a factor of two to five between listings (Get Pro Links is 3,000, 6,500 or 7,000 depending on who you ask; Backlink Masterminds is 200 or 1,000), so treat any single figure as an order of magnitude. And a Slack member count includes everyone who ever accepted an invite, which is not the number of people posting swap offers this week.

The Slack groups in detail

Link Exchange Crew is the most explicit about being an exchange. Its site describes weekly automated matching that pairs members with non-competing SaaS companies, a Monday thread for organising three-way exchanges, and members posting a target page, its DR and its niche before negotiating anchor text directly. It says it rejects about 40% of applicants on DR, traffic, content quality and niche fit, keeps agencies and freelancers out of the main channels (there is a separate Talent channel), and claims 18,400 links placed through the community. That last figure is the community's own and we have no way to check it. The ABC emphasis is deliberate: a three-way swap leaves no reciprocal pattern for a crawler to see, which is the same reason it appears in the publisher replies below.

Get Pro Links is run by a SaaS link building agency and is the largest of the vetted groups by its own count. The channel names on its site tell you the model: #Free Link Exchange for swaps, #Paid Collab for placements with a price, #Announcements. The agency's own service is sold in the same place, which is not a criticism, just the business model of every free Slack group on this list.

Backlink Masterminds is Saasy Links' group, joined through a Google Form. The two listings we found disagree on its size by five times, which usually means one is counting applicants and the other is counting the people who stayed. It is built for SaaS brands (the same population as our SaaS guest posting sites list) and the swaps are guest post and link insertion exchanges between them.

Brainspin's #backlinks is the plainest: a free global group that "facilitates backlink opportunities, discussions, and Q&As", one named channel, apply to join. No published size, no published rules.

Marketing Lad is the one that charges. The sign-up page shows a $10 monthly fee with a 24-hour refund, asks for a LinkedIn profile, and lists guest post pitching, link collaborations and a jobs channel. Older third-party lists quote a $20 one-time fee, which is what the page said before; the current figure is the monthly one.

Traffic Think Tank and Superpath appear on most "link building Slack" lists and neither is an exchange group. TTT is Search Engine Land's paid SEO community, with training, news and job posts; its site prints per-channel member counts but not the price, which only appears at checkout, and the $119 a month you see quoted is a third-party figure. Superpath is a content marketing community with a free tier and a $50-a-month Pro; guest post pitches happen there because content people are in the room, not because there is a swap channel. Join either for the people, not for links.

Facebook, LinkedIn and Reddit

The open groups are ten times the size of the Slack groups and a different product. We could not read inside the two Facebook groups or the LinkedIn group without an account, so what follows is what their listings say. The Hive Index describes the 6,000-member Facebook group as one that "encourages exchanging PBNs, guest posts, niche edits, and media publications", the 35,000-member one as covering "guest posting, link services, content writing, and SEO tools", and the LinkedIn group as members buying, selling, or exchanging backlinks, in that order. A group whose own description leads with PBNs and link services is a marketplace with "exchange" in the name.

That is not useless. If you want to know the going rate for a niche edit on a DA 40 site in your niche this month, an hour in these groups will tell you, and we put the published prices for the same thing in how much backlinks cost. It is just not an exchange in the sense the Slack groups mean.

r/linkbuilding is the opposite kind of room: a discussion forum with real practitioners, which the Hive Index lists at about 27,000 members (we could not confirm the count through Reddit's API on 16 September). We did not review its posting rules, so read them before posting a swap request; on most SEO subreddits that kind of post is treated as self-promotion. Use it for the threads on what is working and take the swap request to a group built for it.

What publishers say when a swap comes up

The groups tell you what they want you to know. The better source is what publishers say when nobody is selling anything, and MentionAgent's outreach records have that in bulk, because a reciprocal link is one of the standard things a publisher asks for when a cold pitch reaches them.

Between 7 March and 16 September 2026, customers on the platform had 2,511 conversations in which a publisher replied at least once, with 2,094 distinct domains across 30 workspaces. We matched every inbound message against the vocabulary of a swap: "link exchange", "exchange links", "link swap", "reciprocal", "link back to us", "three-way", "ABC link", "in exchange for a link" and the obvious variants. 278 conversations matched, 11.1% of everything that got a reply, from 231 domains and 22 of the 30 workspaces. In 206 of the 278, the exchange came up in the publisher's very first reply, before any negotiation, which means it is one of the first things a publisher reaches for when a link request lands.

A word match cannot tell you whether the publisher was offering a swap or refusing one, so we pulled a random 60 of the 278 and read them. The split:

• 19 proposed or accepted a swap (32%). "A link exchange sounds good, here is the page." "Share the list of sites you have available for swaps, with DR and niche." "Yes, we're open to a relevant link exchange."
• 6 accepted with a condition (10%): a DR or DA floor, a niche restriction, or ABC-only. These are covered below.
• 33 declined (55%), and 12 of the 33 named a paid price in the same breath. "We handle these as paid placements rather than reciprocal swaps: $275 for an insertion." "We do not participate in link exchanges; we do offer paid insertion in existing and upcoming content."
• 2 were unclear.

Scaled to the 278, that is roughly 90 publishers volunteering a swap and roughly 150 turning one down, a third of whom would take money instead. The declines split further into two voices worth telling apart: the editorial refusal ("we do not trade links, in either direction, and everything on our pages is there because it earned the place") and the commercial one ("no free exchanges, here is the rate card"). The first is a publisher you want a link from and will only get by being worth citing. The second is a publisher selling inventory, and a swap is just the price you were hoping not to pay.

Three more cuts from the same 278.

The share is rising. Swap mentions were 2% of replied conversations in April (12 of 608), 8% in May, 18% in June, 10% in July, 17% in August (101 of 595) and 14% in the first sixteen days of September (93 of 647). Part of that is the customer mix changing month to month, so read it as a range of 10 to 18% since June rather than a trend line, but the April figure is not coming back.

The publishers who raise it are not the bottom of the market. Of the 217 with a Domain Rating on file, the median was DR 47, against DR 52 for every replied publisher. 67 of the 217 were DR 60 or above. That matches what we found in the exchange platform data, where a quarter of inbound swap requests to our own site came from DR 60+ domains: the swap is a tactic of sites with authority to trade, not a substitute for it.

It shows up in the links that got placed. 82 of the 2,511 conversations ended with a link live or confirmed. In 30 of those 82 (37%), a swap, exchange or reciprocal link had been raised somewhere in the thread, across 7 different customer workspaces. We are careful with this one. It does not say swaps work better than outreach; the 82 placements came from the same outreach, and the conversation simply included the publisher asking what they would get. It says reciprocity is part of how a large minority of ordinary placements get negotiated, whether or not anybody joined a group to do it.

The conditions they attach

The communities mostly keep their floors private, so the publisher replies are the clearest statement of what a swap costs in authority. From the 278 threads, paraphrased and with the publishers unnamed:

• Exchanges only with sites above DA 45 and PA 50, with organic traffic, and only in SaaS, software, tech, IoT or AI. Articles are not accepted as the exchange; one-to-one links in existing articles only.
• Free exchanges accepted, but only with sites at DR 88 or higher. (The same publisher bans CBD and gambling placements in the same message.)
• An ABC exchange with a DR 75+ site with 25,000 or more monthly visits.
• "We do ask for an A-B-C link exchange, not a reciprocal link. Do you manage other blogs?"
• "Google does not like direct link exchange, but we can do A-B-C. Are you able to provide a link from another site?"
• A second domain offered in the swap was refused because its DR of 16 "is too low for our link exchange criteria".
• Exchanges only in the education niche, and not from a PBN, link farm or spam blog.

Four things stand out. The floors are high: DA 45, DR 75, DR 88. The niche match is a hard condition, not a preference. Two publishers independently asked for a three-way exchange because a direct one "is not liked", which is the ABC pattern the Slack groups have built whole channels around, and the pattern a white hat profile can least afford to show at volume. And the most common condition of all was implicit: a publisher who asks "which page on your site, and what is its DR" is telling you the swap is priced in authority, and a DR 10 site has nothing to spend. If that is where you are, the honest route is getting your first ten links some other way, and coming back to the groups once you have a page worth trading. How many backlinks you need puts a number on how far that is for a given keyword.

Google's policy, in one paragraph

Google's spam policies list excessive link exchanges, and partner pages that exist only to cross-link, under link spam. The word doing the work is "excessive". Two related sites citing each other is not what the policy describes; a group whose entire output is reciprocal links between strangers is. The communities are aware of this, which is why the vetted ones push three-way swaps, reject applicants and keep the swap channel small. It is also why the publishers above keep asking for ABC. The longer treatment, with the policy wording and the safer alternatives, is in our link exchange guide, and if a profile already carries a cluster of swaps, how to disavow backlinks covers the cleanup; the short version is that the risk scales with volume and with how obviously the pattern is a pattern.

Using a group without living in it

If you join one, the five minutes that decide whether a swap is worth doing are the same five minutes you would spend vetting any link, and we set them out in the platform comparison. In short: open the page the link would sit on and ask whether a reader would click it; check the site sends any traffic at all, because a DR figure with no visitors is what most swap inventory looks like; and check the page is in your niche, since a link from a swap partner in another industry is the one Google's policy is describing. We judge a referring domain on whether it sends real readers, not on its DR, and swap placements score badly on that test because nobody in the swap chose the page for its readers.

Then set a ceiling. A handful of swaps with sites you would have linked to anyway is a normal part of running a website. A swap every week with whoever posted in the channel that morning is a link scheme with a Slack login, and it will show in your profile as a cluster of reciprocal links from sites that share no topic with yours. Track them in the same sheet as everything else (the link building checklist has the columns), with the date and the reciprocal URL, so that a backlink audit six months from now can tell the swaps from the earned links.

When you have outgrown the group

The tell is the queue. The publishers who declined a swap in our threads were, more often than not, the ones with an editorial reason and a real audience, and they were also the ones whose links were worth having. Once your pages are good enough that those publishers would consider citing them, a swap channel is the wrong room, because the people in it are there to trade and the people you now want are not.

At that point the work is outreach: finding the pages that should be citing yours, writing to the person who maintains them (the pitch templates cover the email; blogger outreach tools cover the sending), and handling the reply, including the one in ten that asks what they get in return. That is what MentionAgent does for the customers whose records this page is built on, from prospecting through the reply to the live link, and the swap question is one of the standard replies it handles. If you would rather see the mechanism than take our word for it, link outreach covers the reply data, and automatic link building covers what an agent does with a thread once a publisher answers. If you would rather keep it by hand, manual link building is the same sequence without the agent, and the editorial link building guide is the version where the publisher never asks for anything back.

Frequently asked questions

What is a link exchange community?

A group, usually on Slack, Facebook, LinkedIn or Reddit, where site owners and SEOs post the pages they can link from and the pages they want links to, then pair up. The Slack groups are vetted and quiet; the Facebook and LinkedIn groups are open and mostly a marketplace for paid placements. A matched exchange platform is the same idea with software doing the pairing.

Which link building Slack communities are free?

Checked on each community's own site on 16 September 2026: Link Exchange Crew (free tier plus an optional Pro tier), Get Pro Links, Backlink Masterminds and Brainspin's #backlinks group are free with an application. Marketing Lad charges a $10 monthly fee on its sign-up page. Traffic Think Tank and Superpath Pro are paid, and neither is an exchange group.

Are link exchange groups against Google's guidelines?

Google's spam policies name excessive link exchanges and partner pages built for cross-linking as link spam. A handful of relevant swaps between real sites has never been the problem; a group whose entire output is reciprocal links is what the policy describes. The communities themselves know this, which is why the vetted ones push three-way exchanges and reject a share of applicants.

How often do publishers ask for a link back?

In MentionAgent's outreach records from 7 March to 16 September 2026, 278 of 2,511 conversations with a reply (11%) mention a link exchange, swap or reciprocal link, and 206 of those raise it in the first reply. Reading a random 60 by hand, 19 proposed or accepted a swap, 6 accepted with a DR or niche condition, and 33 declined, 12 of them quoting a paid price instead.

Do link exchanges actually produce placed links?

They did in our records more often than we expected. Of the 82 conversations that ended with a live or confirmed link, 30 (37%) had an exchange, swap or reciprocal link raised somewhere in the thread. That is publishers asking for reciprocity during ordinary outreach, not a community; it says the ask is normal, not that a swap pool is the best place to make it.

What DR do link exchange communities require?

The groups rarely publish a floor; Link Exchange Crew says it rejects about 40% of applicants on DR, traffic, content quality and niche fit. Publishers replying to outreach are more explicit. In our threads the conditions quoted include DA above 45, DR 75 and up, DR 88 or higher, and one reply that turned down a DR 16 site by name. Swaps are a market for sites that already have authority.
