7 Best SaaS Link Building Agencies: Comparison for 2026-2027

A SaaS link building agency gets other websites to link back to your software company's site, which raises your search rankings and domain authority over time. Instead of running outreach in-house, SaaS companies hire these agencies to find relevant publishers, pitch content, and secure placements that pass real SEO value.

Demand for this service has grown fast. According to Ahrefs Keyword Explorer, the term "        

saas link building agency" gets searched around 1,400 times per month worldwide, and that search volume grew by more than 200% since the beginning of 2024. That growth shows software companies are putting more budget into off-page SEO, and that picking the right partner now carries more weight than it did two years ago.

We ranked the agencies below using four criteria. First, verified client review volume and average rating across platforms like Clutch, G2, and Trustpilot, since review count matters as much as the score itself. Second, how much of the agency's work centers on link building specifically, versus link building sitting as one add-on inside a broader SEO package. Third, pricing transparency, meaning whether an agency publishes rates or requires a sales call before sharing a number. Fourth, industry or niche fit, since a SaaS-focused shop and a local business agency solve different problems.

Based on these criteria, our top three picks for 2026-2027 are eSEOspace, saaslinkbuilder.com, and jeenaminfotech.com. Read the full comparison below to see how all 7 agencies compare on price, specialization, and reviews.

1. eSEOspace

eSEOspace is a San Diego-based web design and SEO agency that also runs link building campaigns for clients in real estate, healthcare, education, and ecommerce. The agency was founded in 2019 and has built a review base across Clutch and other platforms, with more than 150 five-star reviews cited on its own site.

Advantages of working with eSEOspace include the following:

• The agency combines web design, technical SEO, and link building under one contract, which suits SaaS buyers who want a single team handling site infrastructure and off-page work together
• Clutch reviews consistently mention responsive communication and on-time delivery across different project types
• eSEOspace serves a range of industries, from healthcare to ecommerce, so campaign strategy adjusts by niche instead of following one fixed template

Disadvantages worth noting before you reach out:

• Link earning represents a smaller share of eSEOspace's listed service focus than web design and general SEO, so buyers who want a link-building-only partner may find the scope broader than needed
• Most published case studies highlight web design and ecommerce results, with fewer standalone link building outcomes shown publicly

Best for: SaaS companies that want website design, technical SEO, and link building handled by one team rather than split across separate vendors.

Reviews online: eSEOspace holds a 5.0/5 rating from 69 verified reviews on Clutch as of September 2026, with clients specifically praising responsiveness and results across service-based and ecommerce industries.

2. saaslinkbuilder.com

saaslinkbuilder is a SaaS-specialized link building agency focused on improving both Google rankings and AI search visibility. Its campaigns combine contextual backlinks, strategic brand mentions, and listicle or comparison placements, with outreach targeting pages already influencing relevant Google search results and AI-generated answers.

Advantages of working with saaslinkbuilder:

• Campaigns are built specifically for SaaS and technology companies, including brands in AI, cybersecurity, fintech, MarTech, and other competitive B2B categories
• Prospecting goes beyond standard backlink databases by mapping relevant Google SERPs and identifying third-party sources already being cited across AI search
• Campaigns can combine contextual backlinks with brand mentions, listicle placements, and comparison placements depending on the client's positioning and visibility goals
• Every backlink opportunity goes through a 15-step quality checklist covering relevance, organic traffic, editorial quality, outbound-link patterns, placement context, and overall website legitimacy
• Delivered placements include a 12-month replacement guarantee and lifetime placement monitoring

Disadvantages worth noting before you reach out:

• The agency specializes in SaaS and technology, so companies outside those categories may be better served by a broader link building provider
• Campaigns start at a minimum commitment of 5 placements per month, which may not suit companies looking for one-off or very low-volume link building

Best for: B2B SaaS and technology companies that already have an internal SEO or growth strategy and want a specialized off-page partner to build backlinks while also improving their visibility across AI search and third-party recommendation pages.

Reviews online: 5/5 on Clutch

3. jeenaminfotech.com

Jeenam Infotech is a B2B SaaS link building agency founded in 2020, working with clients including Omnisend, Surfshark, Hostinger, and CloudTalk. The agency runs manual outreach campaigns focused on editorial backlinks and listicle placements, and pairs that with AI-search visibility work through brand mentions.

Advantages of working with Jeenam include the following:

• A 4.9/5 rating across 32+ reviews on Clutch, with clients citing fast backlink turnaround and consistent communication
• Clients can review and pre-approve every publisher site before a link goes live, which lowers the risk of receiving weak placements
• Monthly packages run from 5 to 30 links, so campaign volume adjusts as budget grows
• Pricing starts at $170 per link or $1,000 per month, published directly on the site rather than gated behind a sales call

Disadvantages worth checking:

• Campaign focus sits mostly with SaaS and B2B software companies, so non-tech brands may not find the same publisher network fit
• The minimum monthly package (5 links) can be more volume than a small site with a limited budget actually needs
• Technical SEO and local SEO sit outside Jeenam's service list, so a full SEO program still needs a second vendor

Best for: SaaS and B2B software companies that want a link building specialist with pre-approval control over which publisher sites carry their links.

Reviews online: 4.9/5 from 32+ reviews on Clutch, plus a 4.2/5 rating from a smaller review base on Trustpilot.

4. SeoProfy

SeoProfy is an Orlando-based SEO agency operating since 2012, offering link building as part of broader SEO campaigns for clients such as Jooble, Preply, AutoDoc, and DMarket. The agency has placed tens of thousands of backlinks across competitive industries during its operating history.

Advantages of working with SeoProfy:

• A 4.9/5 average across roughly 95-99 verified reviews on Clutch, one of the higher review counts among agencies compared in this article
• SeoProfy has won Clutch's Top Link Building Company award, along with recognition for ecommerce SEO work
• The agency runs international and multilingual link building campaigns, useful for SaaS brands targeting more than one country
• A full SEO service list, including technical audits, content, and keyword research, sits alongside link building, so clients get one team for on-page and off-page work together

Disadvantages worth checking:

• SEO packages start around $1,600/month, higher than several link-only specialists on this list
• Link building sits inside broader SEO retainers rather than as a standalone service, so buyers who want link building only may end up paying for services outside that scope
• A small number of reviews mention a limited range of link donor sites and note that price per link could run lower

Best for: mid-size to enterprise brands that want link building bundled with technical SEO, content production, and international search strategy.

Reviews online: 4.9/5 from approximately 95-99 reviews on Clutch, with additional case studies published on the agency's own site.

5. The Links Guy

The Links Guy is a boutique link building shop that works with SaaS and growth-stage brands, with the founder staying directly involved in campaign strategy. Case studies published on the agency's site describe helping one client scale to 30 million annual visitors, and lifting another SaaS brand's traffic six times over in seven months.

Advantages of working with The Links Guy include:

• Case studies document named-client traffic growth, rather than relying on general claims about results
• Founder-level involvement on campaigns, which smaller agencies often use to keep quality consistent while headcount stays low
• Five-star reviews are reported on Clutch, with testimonials from marketers and entrepreneurs featured directly on the agency's site

Disadvantages worth noting before you reach out:

• The exact Clutch review count is not published in detail on third-party comparison sites, so confirm current review volume directly with the agency before signing
• Boutique team size means campaign capacity may be more limited than larger agencies running bigger outreach teams
• Pricing is not published publicly, so getting a quote requires a direct inquiry

Best for: growth-stage SaaS and content brands that want a smaller, founder-involved team instead of a large agency structure.

Reviews online: five-star ratings are reported on Clutch, though the total review count is not broken out in detail on third-party sites, so it's worth confirming directly.

6. Assertive-media.co.uk

Assertive Media is a London-based digital marketing agency offering SEO, PPC, conversion rate optimization, and link building, run by Daniel Foley. Link building sits inside broader SEO campaigns rather than as a standalone offer, and the agency has built a review base across several UK platforms.

Advantages of working with Assertive Media include the following:

• A 5.0/5 rating across 15 reviews on Reviews.co.uk and 28 reviews on Birdeye
• Several reviewers mention no long-term contract requirement, which lowers commitment risk for new clients testing the agency
• Clients cite consistent reporting and honest expectation-setting before campaigns start, including cases where the agency advised against starting a campaign until budget matched the goal

Disadvantages worth noting before you reach out:

• Link building is one part of a broader SEO and PPC offer rather than a standalone specialization
• Trustpilot shows a smaller review base, around 5 reviews at a 4.1/5 average, so rating consistency varies depending on which platform you check
• The agency primarily serves UK-based clients, which may affect time zone alignment for businesses located outside Europe

Best for: UK businesses that want SEO, PPC, and link building handled together by one regional agency.

Reviews online: 5.0/5 across 15 reviews on Reviews.co.uk and 28 reviews on Birdeye; Trustpilot shows a smaller sample at 4.1/5 from 5 reviews.

7. Hybrid Traffic

Hybrid Traffic is a budget-focused link building service built around bulk and natural-link packages, including an offer called Social Fortress. The service is aimed at buyers who want volume at a lower price point rather than a fully managed, boutique-style campaign.

Advantages:

• Pricing sits on the lower end compared to boutique or enterprise link building shops on this list
• Independent reviewers rated customer service response time well, citing same or next-day replies
• The order process is simple, letting buyers start a campaign without a discovery call

Disadvantages:

• Independent reviewers have rated link quality lower than other providers compared in this guide, which means campaigns may need closer oversight from the buyer
• No verified profile was found on major third-party platforms like Clutch or Trustpilot, so most available feedback comes from the company's own site rather than an independent source
• The site interface and reporting were noted as weaker points in outside reviews

Best for: buyers who need a high volume of lower-cost links on a limited budget and plan to review link quality themselves rather than relying on agency vetting alone.

Reviews online: no independent Clutch or Trustpilot profile was found for Hybrid Traffic. Third-party mentions, including a review from Hook Agency, rate link quality around 4/10 while customer service scores higher at 8/10.

What Does a SaaS Link Building Agency Do?

A SaaS link building agency runs a structured process that starts with prospecting. The team identifies websites that already rank for topics related to the client's product and category, checks their traffic and authority signals, and builds a list of realistic outreach targets before contacting anyone. This step matters because a link from an unrelated or low-traffic site adds little SEO value even if the domain metrics look decent on paper.

Outreach follows next. Agencies email site owners, editors, or bloggers with a pitch that usually falls into one of a few categories: a guest post offer, a request to add a resource link to existing content, or an offer to fix a broken link on the target page in exchange for a placement (broken link building). Response rates on cold outreach tend to run low, often in the single digits, which is why agencies send volume and personalize each pitch to the recipient's content rather than sending one templated email to hundreds of sites at once.

Journalist-request link building, historically run through HARO (Help a Reporter Out), is still part of many agency playbooks, though the landscape shifted. Cision shut down the original HARO platform in December 2024 after rebranding it to Connectively, and Featured.com bought the brand and relaunched it as a free service in April 2025. Agencies that still run this tactic now source journalist requests from Featured's relaunched HARO along with platforms like Qwoted and SOS (Source of Sources), pitching expert commentary in response to reporter queries in the hope of an editorial mention and a link back to the client's site.

Digital PR sits alongside outreach and journalist requests as a third approach, and it works differently. Instead of asking for a link directly, agencies build a data study, survey, or newsworthy angle tied to the client's industry, then pitch that story to journalists the same way a PR firm would. A publication covering the story links back to the original source as a citation, which produces links from higher-authority domains that standard outreach rarely reaches.

Once a placement gets confirmed, the agency drafts or edits the content, sends it for approval, and monitors the live link after publication. Ongoing monitoring matters because links get removed, pages get taken down, or a site loses its search visibility months after the placement went live. Agencies that report link status regularly, and replace or contest lost placements, protect the value of the campaign long after the original outreach ended.

Specialized SaaS Link Building Agency vs. General SEO Agency

SaaS companies looking for backlinks usually choose between two agency types: one that only does link building, and a general SEO agency that includes link building as one service inside a broader retainer. Both models can produce results, but the tradeoffs differ enough to affect which fits a given budget and goal.

A specialized agency generally produces stronger link building results, for a straightforward reason: outreach relationships, publisher vetting, and pitch writing take years to build, and an agency that does nothing else tends to reach a level of consistency that a generalist team, splitting time across five service lines, has less room to match.

That said, plenty of SaaS companies will still want a general SEO agency, either because they need SEO and link building managed under one roof, or because they already have a relationship with one. If that's the direction you're leaning, evaluate the agency on more than a service list. Check whether the agency sells SEO as a set of separate line items, or whether its approach is built around principles that produce genuinely strong links. A few markers worth checking for are listed below.

• Digital PR as a named service, not just guest posting and niche edits, since data-driven PR campaigns are widely considered the strongest form of link building available and earn placements from sites that standard outreach can't reach
• A clear stance on E-E-A-T (experience, expertise, authoritativeness, trust), since agencies building authority signals around real business credibility tend to pursue links that hold up over time, instead of links that get penalized or deindexed later
• Semantic SEO as part of their content strategy, since an agency that understands topical relationships and search intent at that level tends to also understand which publisher sites and content angles actually earn links, rather than treating link building as a separate, disconnected task
• Willingness to show or discuss publisher vetting criteria, including how they judge a site's topical fit and traffic quality, rather than defaulting to a domain rating number alone

Based on these principles, three agencies stand out as strong picks for SaaS companies that want a general SEO partner with a link building approach built on more than volume: eSEOspace, Outranki, and Inflow.

eSEOspace pairs link building with a full web presence strategy across design and technical SEO. Outranki builds its SEO service around semantic content strategy and E-E-A-T-focused authority building, including digital PR and strategic link acquisition, rather than treating links as a bolt-on service. Inflow applies the same gap-analysis rigor to ecommerce link campaigns that it applies to the rest of its SEO work. Each one meets the bar above rather than selling link building as an isolated line item.

How To Pick a SaaS Link Building Agency That Will Satisfy Your Needs?

Picking the right agency comes down to matching their approach, pricing, and specialization to your actual goals, rather than picking the agency with the highest star rating alone. A few factors to weigh before signing a contract.

• Confirm their niche fit. An agency with strong SaaS publisher relationships won't necessarily have the same contacts in legal, local, or ecommerce publications, and the reverse is just as true
• Compare pricing models. Per-link pricing makes costs predictable, while package-based pricing (for example, "10 links for $X") can hide wide variation in link quality between providers
• Check review volume, not just the average score. A 5.0 rating from 6 reviews carries less weight than a 4.8 rating from 90 reviews
• Ask about link replacement policy. Agencies that replace a link for free if it gets removed or deindexed protect your investment better than ones that treat every placement as final
• Review sample placements or case studies from SaaS companies in your category, not just the agency's biggest-name client logos
• Confirm reporting frequency and format upfront, since monthly link reports with live status checks catch problems faster than a one-time delivery list

How To Test a SaaS Link Building Company?

Before signing a contract, run a short vetting conversation with each agency you're considering. The following order works well because each question filters out weaker providers before you get to the next one.

1. Ask them to describe how they work. A strong agency explains their prospecting, outreach, and vetting process in specific terms. A weak one gives a vague answer about "high-quality backlinks" without describing an actual process.
2. Ask for example domains where they'd get backlinks in your niche. This tests whether they already have relevant publisher relationships in your SaaS category, or whether they'd be starting outreach from zero once you sign.
3. Ask whether they focus on DR, traffic, or Trust Flow as their main quality filter. If the answer is yes, and that's the main thing they check, treat that as a warning sign of a mediocre agency. A high-end agency looks past those surface metrics to a domain's actual source context: what kind of content the site normally covers, whether it links out to spammy or unrelated sites, whether the page your link sits on will actually get seen and clicked by real readers, and the ratio between a domain's referring domains and its outgoing external links.
4. Ask if you'll get to pick the websites yourself. If their model is a fixed package, like "10 links from DR 50+ sites per month" with no site list shown in advance, treat that as a warning sign, since it often means links sourced from a shared marketplace rather than a genuine outreach process. If instead they say you'll see and approve each site before it's used, and that the domains aren't ones typically found on public link marketplaces, that's a stronger sign of quality control.
5. Ask what happens if a placed link gets removed or deindexed after the campaign ends. A strong agency has a clear replacement or refund policy built into their contract. An agency that has no answer, or treats every placement as final regardless of what happens to it later, is putting the entire risk on you after the invoice is paid.
