1. Flying Cat: SaaS & global SaaS brands
Our distributed, hybrid team of 25 specialists works exclusively with SaaS and international brands like ActiveCampaign, Cloudtalk, and Leapsome.
As the founder of Flying Cat, I’ve built our team around a simple idea: SaaS companies need link building that actually drives pipeline, not just vanity metrics.
What makes us different? We understand the complex SaaS buying journey and build links that influence decision-makers at each stage. All our link building is done in-house, and we have very stringent qualification rules:
- No PBNs
- Stable traffic AND good DR
- MUST be relevant to your niche – no multitopic websites (we won’t build a link from a website that talks about SaaS and gardening)
We’ve found that effective SaaS link building needs to support the entire funnel – from thought leadership content that builds awareness to strategic backlinks for comparison pages that drive conversions.
Additionally, as an international SEO agency, we provide multilingual link-building services for SaaS, in most European languages and still niche-relevant.
Unlike generalist agencies, we’ve developed deep relationships with tech publications, SaaS review sites, and industry influencers who can provide contextually relevant backlinks that actually move the needle on lead quality, not just traffic.

2. Chase Your Dreams Consulting: Fashion brands
Glynis Tao founded Chase Your Dreams Consulting after spending over 20 years in the apparel industry as a clothing brand owner herself. Based in Toronto, Ontario, Canada, her agency brings a rare combination of fashion industry experience and SEO expertise to ecommerce businesses.
What makes this agency special is their insider understanding of fashion ecommerce. They know the seasonal challenges, trend-focused content needs, and visual nature of fashion marketing that generalist SEO agencies simply don’t grasp.
While their client list isn’t publicly shared, their approach focuses on fashion-specific link building strategies that connect brands with style bloggers, fashion influencers, and industry publications that drive qualified traffic.
Fashion ecommerce has unique challenges – seasonal inventory, trend-based content, and highly visual product pages. Their link building strategies are specifically designed to address these challenges, focusing on content that resonates with fashion audiences.
Unlike generalist agencies that might chase any high-authority backlink, Chase Your Dreams Consulting targets style blogs, fashion forums, and industry publications that actually influence purchasing decisions in the fashion world.
3. Varn Health: Healthcare brands
Led by founder Tom Vaughton in the United Kingdom, Varn Health is a specialist SEO agency dedicated exclusively to healthcare, pharma, and biotech sectors.
What impressed me most about Varn Health is their client roster, which includes major healthcare players like GSK, Pfizer, Roche, Stryker, and Kyowa Kirin. This level of trust from established healthcare companies speaks volumes about their expertise.
Healthcare link building comes with unique regulatory challenges that most agencies aren’t equipped to handle. Varn Health combines technical SEO expertise with a deep understanding of healthcare compliance requirements, ensuring their link building strategies don’t put clients at risk.
Their approach combines advanced technical SEO, AI search optimization, data analytics, content outreach, and paid media to deliver visibility that actually works in the highly regulated healthcare space.
For healthcare companies navigating complex regulatory environments, having an agency that understands both SEO and industry compliance is invaluable. Their specialized knowledge helps clients avoid costly mistakes while still building authority in medical and healthcare publications.
4. SirLinksAlot: Casino and gambling brands
Co-founded by Chris Tzitzis in the United States, SirLinksalot has made a name for themselves in one of the most challenging link building spaces – casino and gambling websites.
They’ve worked with over 1,000 brands (specific clients aren’t listed publicly) and specialize in services like managed link building, guest posts, niche edits, and specialized links specifically for casino and gambling websites.
The gambling industry faces some of the toughest link building challenges out there. Many sites won’t link to gambling content, and Google applies extra scrutiny to this niche. SirLinksalot has developed strategies to overcome these obstacles while staying within search engine guidelines.
What stands out about their approach is their focus on sustainable link building in a niche where shortcuts are common but dangerous. They emphasize white hat techniques that build lasting authority rather than quick wins that might trigger penalties.
For gambling and casino sites looking to improve their rankings without risking their organic visibility, having an agency that understands the unique challenges of this regulated industry creates a significant competitive advantage.
5. Cannabis Link Building: cannabis brands
With 20+ link-building experts, Cannabis Link Building offers specialized outreach services exclusively for the cannabis sector – another highly regulated industry where standard link building approaches often fail.
They’ve worked with over 200 cannabis-related companies and have developed tailored link-building strategies to enhance online visibility and search rankings in this challenging niche.
The cannabis industry faces unique obstacles in link building. Many mainstream publications won’t accept cannabis content, banking restrictions complicate business relationships, and regulations vary dramatically by region. Their specialized knowledge helps clients navigate these challenges.
What makes their approach effective is their focus on building relationships with publishers who are open to cannabis content while ensuring compliance with varying state and federal regulations. This saves clients countless hours of rejected outreach and builds sustainable authority.
For cannabis companies struggling to gain visibility in search, having an agency that understands both SEO best practices and industry regulations helps them build authority without triggering penalties or compliance issues.
6. CoinScribble: Crypto & blockchain
Based in New York, CoinScribble specializes in crypto press release distribution and link building services specifically designed for blockchain projects and Web3 companies.
They’ve worked with over 1,200 Web3 companies and offer guaranteed coverage in leading crypto media outlets, giving clients exposure to millions of potential investors and users.
Crypto and blockchain companies face unique link building challenges. The industry moves incredibly fast, terminology evolves weekly, and many publishers are skeptical of blockchain projects after previous market cycles. CoinScribble’s specialized knowledge helps clients navigate this environment.
What sets their approach apart is their focus on securing coverage in crypto-native publications that actually influence investor decisions and user adoption. Rather than pursuing generic backlinks, they target outlets where crypto audiences actually spend their time.
For blockchain companies looking to establish credibility in a skeptical market, having an agency that understands both technical blockchain concepts and SEO fundamentals helps them build the authority needed to stand out in a crowded space.
7. The Legal Marketing Company: Lawyers & legal brands
With over 20 years of experience, The Legal Marketing Company has established itself as a go-to resource for law firms looking to improve their online visibility through specialized link building.
While they don’t publicly list specific clients on their website, their two decades of experience in the legal marketing space speaks to their staying power in this competitive niche.
Legal firms face distinct challenges when building links. The industry has strict ethical guidelines about marketing, many topics are sensitive, and legal terminology can be complex for general audiences. A specialized agency understands these nuances that generalist agencies often miss.
What makes their approach effective is their comprehensive service offering. Beyond just link building, they provide website design, SEO, paid search, and content marketing services tailored specifically for law firms, helping them build authority in a highly competitive space.
For legal professionals looking to enhance their online presence, having an agency that understands both search algorithms and legal ethics guidelines helps them attract qualified clients without running afoul of state bar association rules.

Industry expertise
In the decade I’ve been in the SEO industry, I’ve seen this pattern repeatedly: agencies that specialize in your industry deliver better results with fewer headaches.
When evaluating agencies, look beyond surface-level claims of expertise. Ask questions like:
- How many clients have you worked with in our specific industry?
- What unique challenges do you see in building links for our sector?
- Which publications in our industry have you successfully placed content with?
The right agency won’t just have general link building knowledge – they’ll understand your industry’s unique content needs, relevant publications, and audience expectations.
Service offerings
Link building agencies offer vastly different services, from guest posting to digital PR to niche edits. The right mix depends on your specific goals.
For SaaS companies, we’ve found that effective link building strategies typically include:
- Strategic guest posts on relevant tech and industry publications
- Thought leadership placement that positions founders as experts
- Digital PR campaigns tied to original research or data
- Resource link building for comprehensive guides and tools
Ask potential agencies to explain which strategies they believe will work best for your specific situation and why. Their answer will reveal a lot about their understanding of your niche.
Client testimonials and case studies
Past performance is one of the strongest indicators of future results. Request case studies from clients in your industry or adjacent ones.
Look beyond vanity metrics like “number of links built” and ask about:
- Impact on organic traffic and rankings
- Improvement in domain authority over time
- Actual business results the client achieved
- Types of publications where they secured placements
The best agencies will have detailed case studies showing how their link building efforts directly impacted their clients’ business goals, not just their backlink profiles.
Frequently asked questions about link building agencies
How much should I pay for link building?
High-quality link building services typically range from $3,000 to $10,000 per month for ongoing campaigns. The cost varies based on your industry, competitiveness, and goals. For SaaS companies, expect to pay $5,000+ monthly for strategic link building that drives qualified traffic rather than just improving vanity metrics.
Is link building still effective?
Absolutely. While Google’s algorithms have evolved, high-quality backlinks remain one of the strongest ranking factors. What’s changed is the emphasis on relevance and context. Random links from unrelated sites provide little value, while contextual links from relevant, authoritative sites in your industry significantly impact rankings and drive qualified traffic.
What is high quality link building?
High-quality link building focuses on securing contextually relevant backlinks from authoritative websites that your target audience actually reads. These links appear naturally within content, come from sites with consistent traffic and authority, and relate directly to your industry or niche. They prioritize relevance over metrics alone.
What is the best way to build links?
The most effective link building approach varies by industry, but generally includes creating valuable content that naturally attracts links, strategic outreach to relevant publications, and building relationships with industry influencers. For SaaS companies, thought leadership content, original research, and tools often generate the highest quality backlinks.
Why is link building important to SEO?
Link building remains crucial to SEO because backlinks serve as “votes of confidence” from one site to another. Google uses these signals to determine authority and relevance. Sites with strong, relevant backlink profiles typically rank higher than competitors with fewer quality links, even when on-page content is similar.
What is the best link building service?
The best link building service depends on your industry. For SaaS companies, agencies like Flying Cat that understand the SaaS buyer journey deliver the most effective results. The ideal service combines industry expertise, transparent reporting, and strategies that prioritize relevance and quality over link quantity.
What is a link building agency?
A link building agency specializes in creating strategies to earn backlinks to your website from other sites. Unlike general SEO agencies, dedicated link building agencies focus specifically on building your site’s authority through manual outreach, content placement, digital PR, and relationship building with publishers in your industry.
What are your link building strategies?
At Flying Cat, our link building strategies for SaaS companies include thought leadership placement, strategic guest posting on industry publications, digital PR campaigns centered around original research, and resource link building. We focus on securing links from sites that influence buying decisions in the SaaS space.
Why is it important for search rankings?
Backlinks remain one of Google’s top ranking factors because they serve as independent validations of your site’s authority and relevance. Sites with strong, relevant backlink profiles typically outrank competitors with similar content but weaker link profiles. Quality backlinks also drive referral traffic from potential customers.
What are the best SEO link building companies in the US?
The best US-based link building companies include specialized agencies like SirLinksalot and CoinScribble, though the ideal partner depends on your industry. For SaaS companies specifically, agencies with expertise in tech and software marketing deliver the most effective results regardless of location.
