5 Best White Hat Link Building Agencies (2026 Review)

How We Ranked These White Hat Link Building Agencies

Link building has one of the widest quality gaps of any SEO service. Two agencies can quote you the same monthly fee, deliver the same number of links, and take you in completely different directions with Google. 

Here’s how we evaluated each agency on this list:

• White hat methodology: How the agency sources links, end to end. We looked for transparent editorial outreach, digital PR, and resource page placements, and ruled out anyone leaning on PBNs, link exchanges, or paid links dressed up as guest posts.
• Link placement quality: Minimum DR/DA thresholds, topical relevance to SaaS and B2B software, and whether links get you placed on publisher sites with genuine traffic.
• SaaS-specific expertise: SaaS link building isn’t the same as ecommerce or local SEO link building. We prioritized agencies with a genuine track record in B2B software and an understanding of how SaaS buyers research, compare, and choose tools.
• Placements on LLM-cited publishers: ChatGPT, Perplexity, and Claude pull heavily from a defined set of high-authority publishers, category roundups, and comparison sites when answering buyer queries. We looked at whether an agency consistently places links on those specific sites, so every backlink pulls double duty as an SEO signal and an AI citation opportunity.
• Reporting transparency: Whether every link is reported with anchor text, referring domain metrics, target page, and placement URL, or whether you get handed a summary number and asked to trust it.
• Pricing model and contract flexibility: Clear deliverables, realistic monthly costs, and terms that match your growth stage without locking you into a year-long commitment before you know if the strategy is working.
• Verified client results: Named case studies, Clutch, Reddit, and G2 reviews, alongside references from SaaS teams at a similar growth stage to yours.

Here’s how the five agencies stack up against each other on those criteria:

Best 5 White Hat Link Building Agencies Compared for 2026

1. Scalerrs: Best for SaaS-Only White Hat Link Building With AI Search Optimization Built In

Scalerrs is a SaaS-only link building agency built specifically for B2B software companies. With 80+ SaaS clients on our roster, every backlink we build is earned through manual editorial outreach on publications your buyers read, and designed to work double-duty as a Google ranking signal and an AI citation opportunity.

Key Services

1. White Hat Editorial Link Building on SaaS-Relevant Sites

Every link we place is earned through manual outreach to editors at real publications. Our team maintains a curated database of high-authority SaaS blogs, category-specific publications, and B2B industry sites your buyers trust. We pitch content ideas publishers want to run, then secure links inside relevant editorial context.

Every site we work with is vetted against a strict quality bar: minimum Domain Rating thresholds, verified organic traffic, topical relevance to your product category, and editorial standards that survive Google's spam updates. No PBNs, no link exchanges, no paid placements dressed up as guest posts. If a link goes down or the placement changes, we replace it at no additional cost.

Scalerrs Founder Jules Davies makes the case for why backlinks still matter more than ever, even in the AI search era, in this LinkedIn post:

2. Placements That Earn Both Rankings and LLM Citations

According to AirOps, 85% of brand mentions in AI search come from third-party sources rather than a brand’s own domain. And unsurprisingly, LLMs pull from a fairly predictable set of publishers when they answer buyer queries in the B2B SaaS category. 

Our SaaS AEO agency work maps those specific sites for your product category, and we weight our outreach targets toward the publishers already earning citations in your space. So when a placement goes live on a publisher LLMs already trust, the same link that lifts your organic rankings also grows your AI citation footprint.

We track AI citation share as a standalone metric alongside domain rating and organic keyword movement, so every monthly report shows how link building has moved your presence across LLMs.

Working with us, Morgen hit 4,000+ AI citations in 30 days. AutoRFP grew from 1,412 to 6,710 organic visitors in six months, accumulated 2,116 brand mentions across LLMs, and reached an average AI position rank of #3. Default generated $300K in pipeline in a single month from combined AEO and SEO work.

3. Reddit Marketing Handled the White Hat, Community-Native Way

Reddit is now cited heavily across LLMs and increasingly surfaced in Google results, which makes community presence a legitimate extension of any modern off-page strategy. 

Our Reddit marketing agency service is built around a fully disclosed, brand-native playbook: engaging as your branded Reddit account, participating authentically in relevant subreddit conversations, managing your product’s own subreddit where relevant, and pitching your solution only when the context genuinely fits.

Fake accounts, vote manipulation, and promotional spam are all off the table. When your product isn’t the right fit for a user’s use case, we tell them and recommend an alternative. This builds long-term trust with moderators and keeps your account in good standing.

Jules Davies shares the full Reddit playbook we run for clients in this LinkedIn post:

4. Custom Client Portal Where Everything Lives in One Place

Most agencies run their client operations out of shared Google Sheets, Notion docs, and email threads that get abandoned sooner rather than later. We built our own custom client portal, and every account works inside it from day one.

Everything sits in one operational environment: your full link building campaign and backlink history, SEO strategy and keyword tracking, content pipelines and editorial reviews, AEO citation tracking, monthly reporting, and your 90-day roadmap. 

On the link building side specifically, you can see every placement as it goes live with target page, anchor text, referring domain rating, placement URL, go-live date, and publisher traffic estimate, and export the full backlink profile to CSV whenever you need it.

Pricing

We offer flexible, month-to-month pricing with no long-term contracts or minimum commitments. Every engagement is scoped around your specific link building goals and can be scaled up or down as needed. Get in touch for a custom quote.

Where Scalerrs Shines

• SaaS-relevant editorial links only: Every placement goes live on a publication your buyers read, so links pass topical authority and drive referral traffic that converts.
• End-to-end organic growth partner: SEO, AEO, content creation, Reddit, YouTube, Wikipedia, and link building all run under one roof, from one strategy, with one team.
• Dedicated pod with senior-only specialists: Named operators on every account, direct Slack access, 30-minute response times during business hours, weekly progress updates, and monthly performance reports.
• No lock-in contracts: Month-to-month engagements, no minimum commitment. If we’re not delivering, you can walk.
• Proven results across 80+ SaaS clients: 4x organic traffic for Reporting Ninja, 4,000+ AI citations for Morgen in 30 days, $300K pipeline in a month for Default.

Where Scalerrs Falls Short

• Not built for pre-PMF SaaS companies: If you haven’t nailed down your ICP yet, our process is too structured for the level of experimentation your growth stage calls for. We work best with SaaS companies that already know who they’re selling to.
• SaaS only: If your business sits outside B2B SaaS, we’re not the right fit. We’ll tell you on the first call and point you toward a better-fit partner.
• Not a one-off link vendor: We don't sell single placements or per-link packages. Our engagements are ongoing campaigns built around a strategy, not a shopping list.

Customer Reviews

“We got to 29,000 clicks per month. That's a 3x increase in really just four or five months. Signups are up 125% year over year. It's an investment that pays off across the funnel,” shares Jim Hartung, Head of Growth at Morgen.

“I like how the team approached Reddit. They were really looking to build good content for the community. And now, when an inbound lead comes, they say they heard about us on Reddit,” says Robert Dickson, Demand Gen/RevOps Manager at AutoRFP.

“Scalerrs has been the fastest agency in getting everything the way I wanted to have it. I'm considering you like a business partner, not only an agency. I see that you really do care about my business,” shares Luis Pereira, Founder at Reporting Ninja.

Who Scalerrs Is Best For

• Growth-stage and mid-market B2B SaaS companies with product-market fit that are ready to scale organic as a serious pipeline channel.
• SaaS marketing leaders reporting to a CMO or board who need link building tied to pipeline, ARR, and AI citation share.
• Teams recovering from a bad prior link building agency and looking to rebuild toward a cleaner, higher-authority link profile.
• SaaS teams that want AI citation growth built into every link placement, without hiring a separate AEO agency to manage it.

2. uSERP: Best for Enterprise SaaS Link Building on Tier-1 Publications

uSERP is a Denver-based link building and digital PR agency founded in 2019 that focuses on high-authority editorial placements for funded SaaS, tech, and enterprise brands. 

Key Services

• Editorial link building and digital PR: The uSERP team runs manual outreach campaigns to editors and journalists at tier-1 publications, earning contextual placements, brand mentions, and bylined content on high-authority domains.
• Link acquisition targeting AI-cited domains: uSERP identifies which publishers LLMs and AI Overviews reference for a given category, then weights their link building outreach toward those specific domains.
• Enterprise SEO consulting and content: Beyond link building, uSERP offers SEO audits, content writing, and strategic consulting for growth-stage and enterprise SaaS brands.

Pricing

Every plan starts with an initial 3-month engagement that rolls month-to-month afterward with a 30-day out.

Where uSERP Shines

• Reach into tier-1 business and tech media: uSERP has direct editor and journalist relationships at national business, tech, and finance publications typically out of reach for pure outreach-based agencies. Placements at that tier are routine deliverables.
• Documented enterprise-scale results: Public case studies show measurable outcomes across a client roster that includes monday.com, Freshworks, and Nav, with specific traffic, ranking, and pipeline numbers attached to each engagement.
• Direct E-E-A-T signal reinforcement: Every placement is on the kind of editorial publication Google’s E-E-A-T framework treats as an authority signal, which directly reinforces the trust markers that increasingly influence rankings on YMYL and competitive commercial queries.

Where uSERP Falls Short

• No community or video services: uSERP focuses on Google-targeted editorial links. Reddit marketing, YouTube visibility, and Wikipedia development sit outside their scope, so brands wanting a multi-surface footprint need additional partners.
• Premium pricing tier only: With starting retainers around $5,000/month and enterprise engagements at $10,000+, uSERP is out of reach for growth-stage SaaS teams working with tighter budgets.

Who uSERP Is Best For

• Funded, later-stage SaaS and enterprise brands looking to close a heavy backlink gap through tier-1 editorial placements.

3. GrowthMate: Best for Done-For-You White Hat Link Building

GrowthMate is a relationship-based, white-hat link-building agency focused on B2B SaaS and service brands.

Key Services

• Manual outreach through publisher relationships: They run manual outreach campaigns using established editor relationships across SaaS and B2B publications, with every placement earned through direct pitching rather than automated tools or content marketplaces.
• Guest posts, listicles, and unlinked brand mentions: Deliverables span editorial guest contributions, inclusion in comparison listicles, and reclamation of existing unlinked brand mentions on relevant sites.
• All-in-one client dashboard: Every account works inside a shared dashboard tracking link progress, keyword position growth, and monthly budget, alongside communication over Slack or email.

Pricing

GrowthMate uses a pay-after-delivery model, invoicing only once the agreed monthly quota of backlinks has been delivered. Pricing is custom-scoped based on link volume and target metrics.

Where GrowthMate Shines

• Pay-after-delivery pricing model: GrowthMate doesn’t take money upfront. Clients only pay once the agreed monthly quota of backlinks has been delivered, which aligns incentives more tightly than most retainer-based arrangements in the category.
• Guaranteed monthly delivery from DR 50+ sites: Every engagement specifies a minimum monthly link count from sites with a Domain Rating of 50 or higher, and delivered links average DR 72. Lost or nofollow links are covered under standard engagement terms.
• Documented outcomes at scale: Public case studies show measurable results including DR lifts, up to 8x monthly traffic growth on individual engagements, and consistent monthly delivery of 30-40 placements on ongoing campaigns.

Where GrowthMate Falls Short

• Link building is the only service: GrowthMate doesn’t offer SEO strategy, content production, AI search visibility work, Reddit marketing, YouTube visibility, or Wikipedia development. Brands wanting a more integrated organic growth stack need additional partners.
• Pricing isn’t disclosed: The pay-after-delivery model reduces the risk of paying for undelivered work, but it doesn’t remove the upfront ambiguity of not knowing what a monthly quota will cost until you have gone through the discovery call and received a custom quote.

Who GrowthMate Is Best For

• Scaling B2B SaaS teams without an internal SEO function that want a fully managed, done-for-you link building program.

4. Chilli Fruit: Best for Boutique Link Building With a Wider SEO Service Scope

Chilli Fruit Web Consulting is a boutique link building and digital PR agency working with B2B SaaS and tech brands across U.S. and European markets. 

Key Services

• Handmade link building on relevant publications: Relationship-driven manual outreach for a minimum of 5 premium backlinks per month, with every placement evaluated for both SEO value and potential to surface as an AI citation.
• Digital PR through HARO and Qwoted: Response-driven pitching to journalists via HARO and Qwoted, plus brand-mention outreach to secure editorial coverage on high-authority publications.
• Google Disavow campaigns: Backlink audits and disavow campaigns to clean up toxic link profiles, which is a service most link building agencies don’t offer.

Pricing

Chilli Fruit uses a “pay-on-results” model with a minimum of 5 premium backlinks per month on the handmade link building service. Wider engagements combining link building with content optimization, digital PR, or SEO consulting are custom-scoped.

Where Chilli Fruit Shines

• Free replacement guarantee for missing links: Placements are backed by free replacement if a link drops, which reduces the risk of paying for backlinks that don’t stick.
• Wider service scope than most boutique link building agencies: Beyond outreach, the team covers onsite content optimization, content creation, Google Disavow, and SEO consulting under one roof.
• Bespoke 1:1 client approach with 24/7 live reporting: The team runs a limited client roster and builds a custom strategy for every engagement, with real-time campaign reporting on demand.

Where Chilli Fruit Falls Short

• Small team, limited capacity: The boutique model means fewer available slots and slower scale-up if your link volume requirements grow mid-engagement.
• No multi-surface off-Google presence: Chilli Fruit’s scope stops at Google-focused link building and digital PR. Reddit marketing, YouTube visibility, and Wikipedia development all sit outside their offering, so brands wanting to build citation surfaces beyond search need to bring in additional partners.

Who Chilli Fruit Is Best For

• B2B SaaS and tech brands wanting a hands-on agency with a broader SEO service scope beyond link building alone.

5. Page One Power: Best for Custom Manual Outreach at Scale 

Next on our list of the best white hat SEO link building agencies is Page One Power. It’s a Boise, Idaho-based agency founded in 2010 with a fully in-house, US-based team that has served 1,000+ partners and built 75,000+ links since inception.

Key Services

• Custom link building across six defined tactics: Page One Power runs manual outreach across six key areas: digital PR, outreach link building (leveraging your existing backlink portfolio), resource link building, broken link building, guest post link building, and unlinked mention link building. Every campaign is scoped around the mix that fits your existing link profile.
• Linkable asset creation for resource and content-driven campaigns: The team has created 6,100+ onsite linkable assets for clients across 15+ years, then promoted those assets through manual outreach to earn placements on relevant resource pages.
• Technical and backlink audits as pre-work: Before starting a campaign, Page One Power runs technical SEO audits and backlink profile audits to ensure your site is set up to compound the value of every link built.

Pricing 

Page One Power’s custom link building service starts at $3,700/month, with every campaign custom-scoped based on target link volume, publisher tier, and campaign complexity.

Where Page One Power Shines

• Backlink gap audit as the campaign starting point: Every engagement opens with a competitive backlink gap audit that identifies which link types, authority levels, and topical clusters actually move rankings for your target pages.
• Real-time per-link transparency in reporting: Clients see every placement as it goes live with publisher DR, organic traffic, anchor text, and target URL, alongside ongoing anchor text strategy refinement based on how their overall backlink footprint evolves.

Where Page One Power Falls Short

• Not SaaS-specialist: Page One Power works across 27+ verticals, from finance and healthcare to hospitality, retail, and tourism. Brands wanting a category-specific publisher network and SaaS-tuned link building strategy need to look elsewhere.
• Google-first link building focus: Their core scope is manual outreach for Google-referring publishers. Reddit marketing, YouTube visibility, and Wikipedia development all sit outside their offering.

Who Page One Power Is Best For

• Established brands that need a link building specialist with a long-tenured, US-based in-house team.

How to Choose the Right White Hat Link Building Agency for Your SaaS

Every agency in this category claims to be white hat. Very few will show you the evidence when you press them on it. This four-step framework helps you separate the operators from the marketers before you sign.

1. Get Clear on Your Requirements First

Define what a successful engagement looks like for your team: monthly link volume, minimum Domain Rating threshold, target publisher categories, contract type, and how link building fits into your broader SEO and content strategy.

If you already know you need 15+ links per month on SaaS-relevant publications with AI citation potential built in, your shortlist looks very different from someone who wants 5 one-off DR 30 links for a quick domain authority push.

At Scalerrs, every engagement starts with mapping your ICP, keyword universe, and pipeline goals, then working backward to what the link building program needs to deliver. Our free SaaS Link Building Playbook walks through the exact process.

2. Vet the White-Hat Methodology Openly

Before signing, ask for:

• 20 previous placements for a client in a similar category, with target page, anchor text, referring domain rating, and publisher URL
• Named list of publishers they have placed on in the past six months
• Explicit position on PBNs, paid guest posts, and link exchanges
• Link replacement policy if a placement drops

If they hesitate, deflect, or send you generic proof rather than specifics, treat it as a red flag. Real editorial agencies have this information ready to share.

At Scalerrs, every prospective client gets a shortlist of recent SaaS placements before we ever discuss pricing. It’s how we prove the quality bar upfront rather than asking you to trust the pitch.

{{cta-general="/cta/link-building"}}

3. Ask About AI Citation Integration

Buyers now research and shortlist software through LLMs before they touch Google, so link building strategies that ignore AI citation surfaces leave half the acquisition equation unaddressed. When evaluating an agency, ask:

• Do you map AI-cited publishers for our category as part of outreach targeting?
• Do you track AI citation share as a reported metric alongside domain rating and keyword movement?
• Can you show a client where you moved AI citation share from links you built?

If they cannot answer confidently, they’re still building for 2021. Our SaaS AEO agency service builds AI citation growth into every campaign we run.

4. Understand Reporting Transparency and Contract Terms

Before signing anything, get clear on what you’re committing to and how progress will be reported:

• Contract length and lock-in terms
• Per-link reporting detail (target page, anchor text, referring domain rating, placement URL, go-live date)
• What happens if placements drop
• Whether reporting ties to business outcomes (organic traffic, pipeline, AI citations) or stops at output metrics (link count delivered)

The right agency’s contract terms and reporting cadence should match how your team already operates rather than forcing you to adapt to theirs.

Scalerrs offers month-to-month engagements with no minimum commitment and per-link transparency tied to pipeline attribution alongside DR and AI citation share.

FAQs

1. What is the difference between white hat and grey hat link building?

White hat link building earns backlinks through manual editorial outreach on sites with real traffic and standards. Grey hat blurs the line with paid guest posts, link exchanges, and marketplace-bought links that violate Google’s guidelines but aren’t outright spam.

2. How long does it take to see results from a white hat link building campaign?

Expect Domain Rating and keyword position movement within 3-6 months of consistent white hat link building. Pipeline impact typically follows within 6-9 months, depending on your starting domain authority and how tightly campaigns tie to commercial-intent pages.

3. How much should a SaaS company budget per month for link building?

Early-stage SaaS teams budget $2,000-$5,000 per month for per-order placements. Growth-stage teams spend $5,000-$10,000 on managed campaigns. Enterprise brands targeting tier-1 publications typically run $10,000-$20,000+ per month.

4. Can white hat link building help with AI search and LLM citations?

Yes. LLMs like ChatGPT, Perplexity, and Claude cite content from high-authority publishers Google already trusts. Placements on those exact publishers grow AI citation share alongside organic rankings, which is why white hat link building drives visibility on both surfaces.

5. Should I hire a white hat link building agency or build links in-house?

In-house link building requires a full-time outreach specialist, publisher relationships that take years to build, and content production capacity. For most SaaS teams sub-100 employees, an agency delivers faster results at a fraction of the fully loaded in-house cost.
