7 Best Link Building Agencies for Organic Growth

If you’ve tried building your website's backlink profile in-house, you know how quickly the process gets kicked to the curb. 

In a 2025 survey of 821 link builders, 55.7% said link building is the most difficult part of SEO. It involves prospecting sites, courting editors, and creating linkable assets. 

And even then, you can't count on the results without the right tools and niche expertise. This is one dilemma that ushers many marketing leaders to the market for a link building agency.

In this article, we break down the seven best link building agencies of 2026. The top options right now include Scalerrs, Linkbuilder.io, Chilli Fruit, Markitors, Editorial.Link, dofollow.com, and Skale.

You’ll understand the strengths of each, where they fall short, and which to work with depending on your business’ needs.

How We Ranked These Link Building Agencies?

In curating this list, we looked beyond popularity to ensure a fair evaluation. These are the factors we considered when ranking the top link building agencies:

• Quality and relevance of backlinks. We prioritized agencies that consistently secure links from relevant and authoritative websites. 
• Measurable client results and verifiable reviews. We looked for proof of impact through case studies, client outcomes, and independent reviews from Clutch..  
• Outreach strategy and ethical practices. Only agencies using white-hat outreach methods made the list. We excluded providers relying on low-quality link schemes.

#4. Anchor Text Strategy

Unlike agencies like Chilli Fruit, Scalerrs is in control of your anchor texts. We optimize for keyword-rich, exact-match anchor texts mapped to target blog and product pages. 

#5. Transparency at Every Stage 

Clients review placements before outreach begins, with weekly and monthly reporting keeping everyone informed throughout. Link building engagements at Scalerrs look more like partnerships and less like a vendor relationship. 

What is Scalerrs’ Pricing?

Scalerrs pricing for link building is a fixed monthly cost, which you can pause or cancel at anytime. Compared to onboarding freelancers and hiring in-house, our team delivers superior value at a competitive price point. Schedule a call for a custom quote.

Where Scalerrs Shines

• Industry expertise in B2B SaaS. Scalerrs isn't a generalist agency that happens to serve SaaS clients. We have several SaaS-specific case studies with verifiable business outcomes.
• Priority given to high-traffic sites. Our focus on sourcing backlinks from sites with 10k+ monthly traffic makes each placement more likely to drive brand exposure and meaningful ranking movement.
• Weekly reporting. Scalerrs provides weekly progress updates and a dedicated client portal so you always know where your campaign stands. We don’t leave you guessing until the end of the month. 
• Talent density. The Scalerrs team is a high-performing cohort of SaaS SEO specialists, including thought leaders like Artur Perrella Glukhovskyy, Elena Dyulgerova, and many more. 

Where Scalerrs Falls Short

• SaaS-only focus: We narrow our clientele down to only B2B SaaS companies so we offer deep domain expertise. If you have a business that’s not SaaS, we’ll point you to other agencies. 
• Suite of services: Scalerrs doesn’t do link building alone. Rather, we offer supporting services like placements in 3rd party listicles, YouTube SEO, and Reddit marketing. This makes us unsuitable for businesses seeking an agency that solely does link building.

Scalerrs Customer Reviews

Pricing

3. Chilli Fruit: Best for Affordable Multilingual Link Building 

Chilli Fruit is a link building agency that helps all kinds of businesses transform their online presence with SEO. It is especially geared toward international campaigns, with multilingual link building support and a one-year link guarantee highlighted as part of the offer.

Key Services

• International link building with translation support: Chilli Fruit offers translation services for campaigns targeting non-English markets, making it a viable option for businesses with multilingual SEO needs.
• Flexible order structure: Campaigns are available as one-off batch orders or ongoing month-by-month management, with a minimum of 5 links per batch and a turnaround time of one month. 

Pricing

ChilliFruit’s pricing starts at $1,000 per month and increases based on campaign scope.

• Real-time campaign reporting: Chilli Fruit clients get 24/7 live access to the progress of their campaigns.

Where Chilli Fruit Falls Short

• No client control over anchor texts or pitches: It is not possible to review pitches before they are submitted, and anchor texts default to branded formats directed primarily to the homepage.
• Outdated case studies: The most recent link building case study on their website dates back to 2018, making it difficult to assess current performance.
• Limited strategic transparency: ChilliFruit's primary documented strategy is the ABC link exchange method, with no publicly available playbooks, frameworks, or thought leadership resources.

Customer Reviews

ChilliFruit doesn't currently have a presence on G2, Capterra, or Clutch. As an alternative, the following testimonials are from their own website:

• “Outstanding results with our international link building campaign by Chilli Fruit, solidifying them as our go-to choice.” — Zbigniew Drozdz, Senior SEO specialist at Booksy

4. Markitors: Best for Small Businesses

Markitors is a link building SEO service for small businesses of every industry, platform, and market. Its broader SEO offer is built for small businesses that need strategy, content, and link building managed by one team instead of separate vendors.

Key Services

• Cross-industry coverage: The agency serves clients across a wide range of verticals including healthcare, fashion, and plumbing. 
• Demonstrated search authority: Markitors consistently ranks on the first page of Google for terms relating to small business SEO.

Pricing

Custom. No pricing is publicly listed on the Markitors website. 

Where Markitors Shines

• Full-service delivery under one roof: Small businesses get SEO strategy, content writing, technical optimization, and link building managed by a single team.

Where Markitors Falls Short

• No standalone or specialized link building service: Link acquisition is bundled into a broader "digital PR" offering with no publicly documented methodology, link quality benchmarks, or transparency around DR targets. 
• Dated proof: Markitors testimonials and case studies date back to 5-6 years ago. 

Customer Reviews

• “Their delivery and execution were their strongest suit,” shares Josh Collins, Contract Manager of Marketing, Go Tangent, LLC
• “...The work was nothing short of outstanding quality As great as the work was, the interactions were even better. Brett, Jen, and the rest of the crew work their tails off and do it in a way that makes you feel like so much more than a client. They could not have been easier to work with.”---  Michael Thompson, Owner and CEO at LurnAgile

Who Markitors Is Best For

• Small businesses needing full-service SEO: Companies without an in-house SEO team that want strategy, content, and link building managed under one retainer.

5. Editorial.Link: Best for Mid-market and Enterprise Companies

Editorial.Link is a top link building company that secures editorial backlinks for mid-market and enterprise companies of all industries. It also leans heavily on relationship-based editorial placements and client-approved targeting, which gives buyers more control than most link vendors offer.

Key Services

• Pure-play link building specialization: Editorial.Link only does link building and no other service. 
• Client-controlled targeting: Clients have the flexibility to choose the websites, articles, and anchor texts for each backlink.
• High average domain authority: With an average DR of 67 across placements, Editorial.Link consistently lands links on well-established, high-authority domains.

Pricing

Where Editorial.Link Shines

• Trial backlink option: Prospective clients can order a single backlink before committing to a monthly retainer.
• Workflow transparency and client control: Editorial.Link clients can select target websites, articles, and anchor texts, with all progress tracked clearly in Google Sheets and communication managed through a dedicated messenger. 

Where Editorial.Link Falls Short

• Not suited for smaller companies: With a minimum entry point of $375 per link, Editorial.Link is priced for mid-market and enterprise buyers, making the service inaccessible for startups or lean teams with limited budgets.
• No SaaS-specific methodology: Despite serving SaaS clients, Editorial.Link has no openly documented SaaS-specific backlink strategy.

Customer Reviews

• For Kevin Feijoo, Head of Client Relations, Top Notch Cinema “the consistency in delivery and quality of links” gave his company “confidence in the overall effectiveness of the engagement.”
• “What stands out most is how organized and straightforward their process is,” shares Guiselle Rivera, Lead Gen Ops Specialist, Angel Reyes & Associates

• Mid-market and enterprise companies seeking a pure-play link building partner: Organizations with established SEO programs that need a reliable, high-quality link acquisition engine without the overhead of a full-service agency.
• High-growth companies in competitive verticals: Businesses in SaaS, legal, finance, real estate, or insurance that need authoritative, dofollow placements from editorially vetted publishers.

6. dofollow.com: Best for B2B SaaS Brands That Want Link Building Plus AI Visibility

‍

dofollow.com is a strong option for B2B SaaS companies that want more than backlinks alone. Its positioning is built around two related services: link building for organic search and brand mentions for AI visibility. That makes it more relevant than a generic link vendor for SaaS teams that care about both rankings and how their brand shows up in AI-generated answers.

Key Services

• B2B SaaS-only focus: dofollow.com works exclusively with B2B SaaS, which gives it stronger category relevance than cross-industry link shops.
• Two-track authority building: The agency combines classic link building with branded mention placement for AI visibility, which is unusual in this category.
• Manual outreach and editorial collaboration: The process emphasizes personalized outreach, direct editor collaboration, quality assurance, and reporting rather than marketplace-style link buying.
• Real-time reporting: Clients get access to a portal where they can track results, talk to their strategist, and review live reporting.

Pricing

Custom. dofollow.com does not publish public pricing on its main service pages. It frames pricing around backlink quality, domain rating (DR), and a recurring credits-based model.

Where dofollow.com Shines

• SaaS expertise: The whole service is calibrated to B2B SaaS categories, buying intent, and search competition.
• AI visibility layer: The brand mentions offer gives clients an off-page AI-search angle that many link agencies still ignore.
• Clear delivery model: Manual outreach, editorial collaboration, and live reporting make the service easier to trust than vague “we build links” offers.

Where dofollow.com Falls Short

• No public pricing: That makes commercial comparison harder than it should be.
• Limited client control: Clients can suggest ideal sites, but they cannot fully choose websites or anchor text, since editors retain that control.
• Narrower service scope: dofollow.com is a strong off-page authority partner, but it is not a broader SEO/content/growth agency.

Customer Reviews

• “I can’t speak highly enough about dofollow.com. We went from 0 to over 50/mo demos,” shares Trevor Larson, co-founder and CEO at Nectar.
• “They understand the shifting landscape of modern search and consistently deliver high-quality links and brand mentions” says Kevin Indig, Growth Advisor at G2, Shopify, and more.

Who dofollow.com Is Best For

• B2B SaaS companies: That want link building plus AI-visibility support.
• SEO leaders: That care about authority signals across both Google and AI search.
• Teams with an existing content engine: That need stronger off-page support, not a full-service organic growth partner.

7. Skale: Best for SaaS Brands That Want Link Building as Part of a Broader Organic Growth Engine

‍

Skale is a better fit for SaaS companies that want link building inside a broader SEO and AI-search strategy, not as a standalone service. That makes it one of the more full-stack options in this category. It is less of a pure-play link building agency and more of an organic growth partner with link building as one part of the system.

Key Services

• Broader organic growth coverage: Skale combines link building with SEO, GEO, AI citation outreach, and content production.
• Revenue-oriented link building: Its link building offer is framed around pipeline, demos, signups, and revenue impact rather than backlink volume alone.
• Tailored outreach and content creation: The link building process includes a custom strategy, personalized outreach, relationship building, and content creation.
• AI-search readiness: Skale has gone further than many SEO agencies in formalizing GEO and AI citation outreach as services.

Pricing

Custom. Skale does not publish public pricing.

Where Skale Shines

• Strong SaaS growth framing: The agency consistently ties organic work back to demos, signups, revenue, and North Star metrics.
• More than link building: Clients looking for one partner across SEO, AI search, content, and outreach will find more range here than with a pure-play link vendor.

Where Skale Falls Short

• Not a pure-play link building agency: Clients who only want standalone link acquisition should opt for a narrower specialist.
• No public pricing: That makes it harder to benchmark cost up front.
• Closer to a broader growth partner: That can be a strength, but it also makes Skale a less clean fit for clients who want only off-page execution.

Customer Reviews

• “I saw major benefits in link-building, so we decided to work with Skale, which turned out to actually be more cost-efficient & delivered amazing results!” shares Urska, Director of Marketing at Whisbi
• “We're a fast-moving startup with a growing marketing team. Using Skale has enabled us to focus on creating new landing pages and articles, while the Skale team take care of off-page factors that we don't have the time to deal with in-house,” says Kirsty, Content Strategist at Holded

Who Skale Is Best For

• SaaS brands: That want link building inside a broader SEO and AI-search program.
• Growth teams: That care about demos, pipeline, and revenue, not just backlinks.
• Companies that want one partner: Across SEO, GEO, AI citation outreach, and content.

How to Choose the Right Link Building Agency

Different link building agencies engineer very different outcomes. Some help you build sustainable organic growth. Others flood your backlink profile with low-quality backlinks that eventually become a liability.

Before partnering with a link building agency, review how well your organic channel currently performs by starting with our SaaS SEO checklist. After that, when assessing a potential agency partner, verify backlink sources, understand their pricing model, ask for page-level insights, and check for industry expertise.

{{cta-general="/cta/saas-seo-checklist"}}

1. Verify Backlink Sources

The best link building agencies are transparent about how they earn links and how they vet publishers.

• Make sure the agency uses ethical, white-hat link building methods instead of spammy tactics like PBNs, low-quality guest posts, or automated outreach. 
• Ask for sample placements and review the websites yourself for relevance, traffic quality, and editorial standards.

At Scalerrs, we’re very open about the types of links we source. We keep to our standard of DR 60+, 10K+ traffic sites because we know that low-quality backlinks damage rankings over time.

2. Understand the Pricing Model

Link building agencies may charge per link, per campaign, or through monthly retainers. Instead of focusing only on price, evaluate what’s included: outreach, content creation, reporting, and link quality standards. Extremely cheap link building often prioritizes quantity over relevance and authority. In SaaS SEO specifically, a few strong backlinks usually outperform dozens of weak ones.

3. Ask for Page-level Insights

Strong link building strategies focus on placing links within relevant, high-performing content. So when you’re vetting, ask whether the page already ranks, receives traffic, and aligns contextually with your niche or target keywords. 

At Scalerrs, we optimize for a strong traffic-to-page ratio so your website links are embedded in pages that pass meaningful SEO value.

4. Check for Industry Expertise

Ask for case studies within your industry and examples of previous campaigns. Industry familiarity usually leads to better outreach, stronger placements, and faster execution.

If you’re a SaaS company, choose an agency like Scalerrs that has built relationships with other SaaS brands and understands the peculiarities of SaaS SEO. You can compare the top contenders in our roundup of the best SaaS SEO agencies for 2026.
