First Things First: What Is a Backlink Marketplace?

A backlink marketplace is an online platform where people can buy, sell, or trade backlinks. You could think of it like an SEO version of Airbnb, but instead of renting apartments, you’re renting space on someone else’s website to drop a link back to yours.

Some backlink marketplaces are open and automated. Others are more curated. A few operate like credit-based exchanges (where you earn backlinks by giving them). The goal is always the same: to help you grow your SEO authority by getting your site linked to from other relevant, trustworthy websites.

“Backlink marketplaces are like dating apps for SEOs — ie. when you match with the right site, things can change fast.”

Why People Use Backlink Marketplaces

Building backlinks the old-fashioned way takes time.

You’ve got to:

  • Find relevant websites

  • Cold email them

  • Write custom pitches

  • Get ignored

  • Follow up

  • Write a guest post

  • Hope they don’t just disappear after publishing and you paying out

With a good backlink marketplace, you skip 90% of that. You get:

  • Pre-vetted sites in your niche

  • Clear pricing or trade terms

  • Faster turnaround

  • Trackable results

 “In 2026, 74% of SEO professionals reported using at least one backlink marketplace as part of their link-building strategy.”

Differences in Backlink Marketplaces

Before we go any further, let me just say this: some backlink marketplaces are super sketchy! Like anything in SEO, there’s a fine line between “clever” and “black hat.”

Red flags to avoid:

  • PBNs (Private Blog Networks) disguised as real blogs

  • Low-quality sites with no traffic or value

  • Too-good-to-be-true DR promises (“Get a DR90 link for $15!”)

  • Over-optimised, AI-generated content farms

  • No transparency about traffic or indexing

The good news? There are plenty of legit platforms out there too — you just need to know what to look for.

The Main Types of Backlink Marketplaces

1.  Traditional Marketplaces (Buy Links or Posts)

These platforms let you browse thousands of websites and pay for guest post placements or link insertions.

Common features:

  • Domain Rating (DR) and traffic filters

  • Pre-written content options or custom articles

  • Set pricing tiers

  • Dashboard tracking and reporting

Best for: Agencies, freelance SEOs, and SaaS brands with a link-building budget.

2. Credit-Based Exchanges (Like 3Way.Social)

Instead of paying cash, you earn credits by linking to other users’ sites, then spend those credits to get backlinks in return.

How it works:

  • You publish a link to another site (via guest post or content edit)

  • You earn credits

  • You spend credits to request a backlink from someone else in your niche

  • Everyone benefits — no money exchanged, no spam

Best for: Bloggers, site owners, or solo marketers who want to grow organically and ethically.

3. Outreach-as-a-Service Platforms

These are more like backlink “agencies” — you tell them your niche and goals, and they find sites and place links for you. It’s semi-automated but still uses marketplace-style sourcing behind the scenes.

Best for: Brands that want results but don’t want to get their hands dirty.

  •  Access to data (DR, traffic, niche relevance) before committing

  •  Scalable (great for agencies managing multiple sites)

  •  Cost flexibility (from free to premium options)

  •  Easier to test campaigns across industries

Cons and Risks (And How to Avoid Them)

  •  Low-quality marketplaces can harm your SEO

How to avoid trouble:

How to Vet a Backlink Before You Buy or Trade

Before you hit “order,” ask:

  • Is this site indexed by Google?

  • Does it have real organic traffic?

  • Is the content regularly updated and original?

  • Does it feel like a site people actually read — or just link to?

3Way tip: Plug the site into Ahrefs and check for branded traffic. If no one’s searching for the domain, it might be a link farm.

Our Tips for Using a Backlink Marketplace Effectively

  • Set a monthly budget or credit goal

  • Diversify anchor text (avoid keyword stuffing)

  • Prioritise link placements inside content, not sidebars or footers

  • Track new links in Google Search Console and Ahrefs

  • Focus on long-term consistency — not spikes

“Getting one link from a DR 50 blog every week is better than blasting 20 spammy ones in a day.”

FAQ: Backlink Marketplace Edition

Q: Are backlink marketplaces safe for SEO?
A: Yes — if you use reputable platforms and prioritise quality. Avoid low-value or spammy links, and always vet the domain before placing a link.

Q: Can Google penalise me for using one?
A: Google penalises unnatural, manipulative links — not the tool you use. Use marketplaces to find real sites and place high-quality, relevant links, and you’re in the clear.

Q: What’s the difference between a backlink marketplace and a link broker?
A: A marketplace lets you browse and choose placements yourself. A broker usually does the work for you behind the scenes. Marketplaces offer more control; brokers offer convenience.

Q: Do backlinks disappear after a while?
A: Sometimes, yes — if the site deletes the post or updates URLs. Choose marketplaces that guarantee link placement for at least 6–12 months (or longer).

Q: Is DR (Domain Rating) all that matters?
A: Nope. It’s one metric. Also check for traffic, niche relevance, and editorial quality. A DR 40 site with real readers is more valuable than a DR 70 ghost town.

Q: How many backlinks should I build per month?
A: It depends on your goals, but 3–5 high-quality backlinks per month is a solid starting point for most websites.

Final Thoughts: Backlink Marketplaces Done Right

Backlink marketplaces are one of the best ways to scale your SEO without burning out or hiring a full-time outreach assistant. They’re faster than manual link-building, easier than PR, and, when used right, 100% ethical and effective.

Just remember:

  • Vet every domain

  • Focus on relevance and content quality

  • Mix in other strategies like HARO, citations, and digital PR

  • Build for the long game
