What is a link building agency
A link building agency, sometimes called a backlink company, earns links to your website from other websites on your behalf. Agencies typically use outreach-based tactics such as guest posting, digital PR and journalist outreach, niche edits (link insertions into existing pages), and broken link building to raise a domain's authority signals and improve organic search rankings. Most link building is sold as an ongoing monthly retainer rather than a one-time project, since sustained authority growth comes from a steady flow of new, relevant links over time.
What link building costs
Typical monthly retainers run from about $3,000 to $10,000, with roughly half of buyers landing in the $5,000 to $10,000 range. Startups can find programs starting around $1,500 a month, while enterprise or highly competitive verticals like finance, legal, and gambling often pay $15,000 or more per month. Agencies that sell links individually rather than by retainer generally charge around $370 to $500 per placement, with premium DR50 to 70 links running $500 or more, niche edits averaging about $361, guest posts around $300 to $600, and digital PR placements from $750 to $2,000 or higher. Results build gradually over an ongoing engagement rather than a fixed project timeline, since link building compounds over months rather than delivering an instant ranking jump.

What is a link building agency?
A link building agency, sometimes called a backlink company, earns links to your website from other websites on your behalf. Agencies typically use outreach-based tactics such as guest posting, digital PR and journalist outreach, niche edits (link insertions into existing pages), and broken link building to raise a domain's authority signals and improve organic search rankings.
Most link building is sold as an ongoing monthly retainer rather than a one-time project, since sustained authority growth comes from a steady flow of new, relevant links over time.
How does link building work?
A link building agency identifies relevant, authoritative sites in your niche and pursues links through several channels: guest posting on industry publications, digital PR and journalist outreach for coverage-driven links, niche edits that place a link inside an existing published article, resource page link building, and broken link building that replaces a dead link with a link to your content.
Agencies typically track link quality using metrics like Domain Rating (DR) or Domain Authority (DA), and pay attention to anchor text diversity and the mix of dofollow versus nofollow links, since an unnatural link profile can draw scrutiny under Google's link spam policies.
How much does link building typically cost?
Typical monthly retainers run from about $3,000 to $10,000, with roughly half of buyers landing in the $5,000 to $10,000 range. Startups can find programs starting around $1,500 a month, while enterprise or highly competitive verticals like finance, legal, and gambling often pay $15,000 or more per month.

Is link building illegal?
Link building itself is not illegal. It is a normal part of SEO, but Google's link spam policies treat certain tactics, such as buying links purely to manipulate rankings or using private blog networks (PBNs), as violations that can trigger a manual action against a site.
White hat tactics like guest posting, digital PR, niche edits on genuinely relevant pages, and broken link building stay within Google's guidelines. Ask any agency you consider how transparent they are about link sources and metrics like DR and referring traffic per placement, since buyer skepticism about inflated or low-quality backlinks is a common concern in this space.
How are the agencies on this page ordered?
Agencies are ordered by partner tier: Certified Partner first, then Partner, then Unverified. Tier reflects an agency's verification status with AIclicks, not a performance score or a ranking of quality. Unverified profiles were compiled from public search results and have not been claimed by the agency yet, so their details are deliberately minimal. Any agency can claim its profile to correct and expand it.
