10 Best SaaS Link Building Agencies in the US

This is a comparison of the 10 best SaaS link building agencies in the US for SaaS founders, CMOs, and SEO managers. Each agency is evaluated on the same criteria: founding year, team size, Clutch ratings, named clients, services, and case study results. Let’s get started. 

Best SaaS Link Building Agencies in the US in 2026

1. SaaSLink Max

Quick specs

• Founded and HQ: 2018; Los Angeles, California, US
• Team size: 10-49
• Clutch: 5/5 stars, 80 reviews
• Named clients: Heepsey, ZeroBounce, SE Ranking, Workyard

SaaSLink Max works exclusively on SaaS link building. They build backlinks through SaaS-to-SaaS placements inside tools your buyers already use daily, earned editorial features in major industry publications, and listicle and comparison page insertions on content that already ranks.

They also secure brand mentions in the sources LLMs pull from, so your tool surfaces when buyers ask ChatGPT or Perplexity for recommendations in your category. The digital PR side is particularly hard to replicate: these are placements journalists have to choose to cover, which is exactly what makes them rare and valuable for domain authority.

What to Check Before You Sign with a SaaS Link Building Agency

The list covers who each agency is, what they offer, and what they have published. These four questions will separate agencies with documented workflows from those that will not deliver.

Look at Clutch review dates, not the rating alone. Five reviews from one quarter is weaker evidence than a 4.8-star rating spread across three years.

Ask for case studies with actual numbers before the sales call ends. Agencies that have done this work will have referring domain counts, keyword position changes, and traffic figures over a defined time frame. If they cannot produce three examples with real data, treat that as disqualifying.

Ask to see past placement examples. A good placement is contextual, within the body of relevant content on a page that has organic traffic. A link on a dead page passes no equity.

Ask about link maintenance. Agencies with a documented process for monitoring and replacing dead links are more reliable than those that treat delivery as the end of the engagement.

Closing notes

The agencies here take different approaches – some offer link building as a standalone service; others embed it inside a broader SEO program. The right choice depends on whether you need a link specialist or a managed organic growth partner.

If a verified track record is the deciding factor, SaaSLink Max (80 Clutch reviews, 5/5), Jeenam Infotech (34 reviews, 4.9/5), and GoPeak (13 reviews, 4.9/5) have the most consistent public evidence. For link building inside a full SaaS SEO program with a large team, Skale and TripleDart both operate at that scale. For per-link pricing without a retainer commitment, LinkBuilder.io offers that model.

For agencies with fewer than five Clutch reviews or no published case study data, SERPs Growth, Marveta, Ranko Media, and Linkflow request references from SaaS clients before proceeding.
