Link building for SaaS is its own discipline. The buyers are researching in comparison posts and alternatives pages rather than blog listicles, the competitors are usually well-funded, and the pages that actually need authority are product, integration and use-case pages that nobody links to naturally. Generalist agencies tend to bring guest posts on low-traffic marketing blogs and call it a day. The five agencies below all work seriously in the SaaS sphere, and they all provide effective link building for businesses.
1. GoPeak
- Founding year: 2023
- Overview: GoPeak is a contextual link building agency built specifically for SaaS companies, and one of the few in the category that publishes flat per-link pricing rather than tiering by domain rating. Every placement is a do-follow editorial link on a site that will actually provide value, sourced through outreach in SaaS and SaaS-adjacent niches, with no PBNs or link farms. Clients see prospects before outreach begins and are provided with spreadsheets detailing necessary information. Alongside classic link acquisition, the team runs blog management and a brand mention service aimed at getting SaaS brands cited in AI answers from ChatGPT, Perplexity and Google’s AI surfaces. Published case studies include My Hours, Sender.net, Referral Rock and systeme.io.
- Services provided: Contextual and editorial link building; internal linking strategy; brand mentions for AI and LLM visibility; backlink audits; anchor text distribution strategy; white-label link building for agencies.

2. uSERP
- Founding year: 2019
- Overview: uSERP is a Denver-based authority building agency co-founded by Jeremy Moser and Brad Smith, and probably the most cited name in B2B SaaS link building. The model is digital-PR-led: unclaimed brand mentions, expert contributions, data-driven resource pages and contextual insertions on high-authority publications. Retainers are published openly, running from roughly $5,500 to $15,000 per month with a defined mix of DR 60+ and DR 20–59 placements, plus a six-month lost-link replacement guarantee. The team works entirely in-house rather than outsourcing outreach, and reports on revenue, MRR and qualified pipeline rather than raw link counts. Named clients include monday.com, Freshworks, ActiveCampaign, BigCommerce, CrowdStrike and Robinhood. Best suited to funded SaaS companies with budget for a six-figure annual programme.
- Services provided: Link building and outreach; digital PR; AEO and AI-SEO services; content writing; enterprise SEO; competitor backlink gap analysis; toxic backlink cleanup; internal linking strategy.

3. Skale
- Founding year: 2019
- Overview: Skale is a London-headquartered agency that works exclusively with B2B SaaS and tech brands, and it frames its entire offer around revenue rather than rankings — engagements start with an SEO revenue model projecting signups, SQLs and new MRR over twelve months. Link building sits inside that wider programme alongside content production, technical SEO, migrations and a growing generative engine optimisation practice focused on AI citations. Prospect domains are screened for topical relevance rather than domain rating alone, and monthly reporting ties individual placements to ranking and signup movement. Published results include a 2,500% lift in organic signups for Happy Scribe and 860% for Piktochart. Clients have included G2, Maze, Slite, Attest and Synthesia. Pricing is not public; minimum engagements start around $5,000 per month.
- Services provided: SaaS SEO strategy and execution; link building and outreach; SEO content production; generative engine optimisation and AI brand mentions; website migrations; SEO revenue modelling and business-impact reporting.

4. Editorial.Link
- Founding year: 2020
- Overview: Editorial.Link grew out of Admix Global, a media publishing business, which gives it an unusual asset: first-hand knowledge of how publishers actually sell and place links. Every prospect is screened with an in-house classifier designed to filter out sites that exist purely to sell placements, and the client approves each domain before outreach begins. All placements are DR 60+, with an average delivered DR of 67, and pricing is flat per link — around $375 for one, dropping to roughly $300 each in bulk — rather than scaled by authority. New clients receive a free trial backlink before signing, and links carry a six-month replacement warranty. Clients include PandaDoc, NordVPN, Depositphotos, Capital.com and Belkins. It will also take orders as small as one or two links a month.
- Services provided: Editorial backlinks; digital PR link building; brand and unlinked mention reclamation; listicle link building for AI visibility; broken link building; linkable asset creation; guest posting; white-label link building.

5. Siege Media
- Founding year: 2012
- Overview: Siege Media is the longest-running agency on this list and the one that most deliberately does not sell links as a line item. Founded by Ross Hudgens, it earns them instead — through data-led research reports, original graphics, interactive tools and digital PR campaigns that publications choose to cite. That is a slower and more expensive path than outreach-driven link building, but the assets keep attracting links long after the campaign ends. The agency has been early and aggressive on generative engine optimisation, with published work on driving ChatGPT sessions for SaaS clients. Its SaaS roster includes Zendesk, Asana, HubSpot, Zapier, Zoom, ServiceNow and Drata. Pricing is not published and engagements are enterprise retainers, so it fits SaaS companies with existing content operations to scale.
- Services provided: Content strategy and production; digital PR; research reports and data journalism; graphic and web design; SEO consulting; generative engine optimisation; affiliate and Reddit marketing.
