The 10 Best SaaS Link Building Agencies, Vetted by an SEO Founder

I run Flying Cat, a founder-led SEO and AI search consultancy for B2B SaaS companies. Link building sits inside every program we run, so I evaluate link building agencies from the buyer side as often as I compete with them. This list covers ten SaaS link building agencies I checked on their own websites in October 2026. I looked at whether each agency still operates, what it sells today, which SaaS clients it names and what it publishes about pricing.

I dropped five agencies from the earlier version of this page. One domain no longer hosts an agency. One agency no longer lists link building among its services. Three others now present SaaS as one industry among many, or do not mention it at all. I also removed a software platform, since a tool you run yourself belongs on a different list.

How I vet a SaaS link building agency

I run these checks when a client asks me to review a link building vendor. We hold our own placements to the same standards.

Ask for the last ten placements with live URLs

A list of domains tells you very little. Ask for the exact URLs of the last ten placements, then check three things on each site. Organic traffic should be stable or growing over the past year. The site should cover one topic close to your category. The page your link sits on should rank for something itself. We reject private blog networks and multi-topic sites outright, even with a high Domain Rating. A site that writes about SaaS one day and gardening the next sends a weak signal to Google and to AI assistants.

Check which pages the links point to and why

Good agencies pick target pages from your conversion data. At Leapsome, the team chose four priority pages by their conversion rate from MQL to sales-accepted opportunity, then moved part of its content budget into link building for those pages. We built around 50 targeted links to them. Referring domains grew about 30% in twelve months. Sequencing also counts. For Trevor.io, every new page first got internal links from older pages that already ranked and got crawled often. External links came only once a page started ranking. Pages reached page one in about a month. Traffic beat the forecast by 402%.

Ask whether a placement shows up in AI answers before you pay for it

AI assistants build their shortlists from third-party roundups, review sites and industry publications. A placement on a page that ChatGPT, Perplexity, Copilot or Google AI Mode already cites for your buying prompts is worth far more than a link on a page no assistant reads. Ask the agency how it measures this. If it cannot show citation data for a target page, it is pricing the placement on Domain Rating alone.

Ask how paid placements are disclosed and billed

Google's spam policies treat paid links meant to pass ranking credit as link spam unless they carry a rel="sponsored" or rel="nofollow" attribute. Paid listicle spots and sponsored articles are common in SaaS, so ask the agency to explain which placements involve a publisher fee and how those fees appear on your invoice. We pass publisher fees through at cost, so clients see what each placement costs separately from our time.

Ask who approves each target

Junior outreach teams send volume. Ask who signs off on each target site before outreach starts and what the rejection criteria are. At Flying Cat, I approve every target before anyone sends an email.

Ask what the report measures

A report built on link counts and Domain Rating tells you what the agency did. It does not tell you whether the work moved pipeline. Ask for reporting on rankings and AI visibility for the target pages, plus demo requests or signups from those pages. Our guide to measuring link building covers the metrics in more detail. Our content and link programs report two primary KPIs, which are the visitor to demo or trial conversion rate and the SQL to opportunity conversion rate.

Check whether the agency will tell you links are the wrong lever

Some sites need technical fixes or better pages before links can help. Softr lifted paid signups 125% in the first two months from technical fixes alone, before we published any new pages. At an ecommerce marketing platform, company policy ruled out link building in France. The client still tripled its top-3 rankings there through native-written content. An agency that sells only links will rarely tell you this.

How AI search changed SaaS link building

Links still count for rankings. AI search has also widened what a good placement looks like. Ahrefs studied 75,000 brands and found that branded web mentions correlated with visibility in Google AI Overviews at 0.664, against 0.218 for backlinks and 0.295 for referring domains. In a June 2025 survey of 518 SEO professionals reported by Search Engine Land, 73.2% said links influence visibility in AI search results. The survey came from Editorial.Link, a link building agency, so read it with that interest in mind.

For SaaS buyers, this means a link building budget should cover two kinds of placements. Classic editorial links help your pages rank in Google. Brand mentions on the roundups and review pages that AI assistants cite get your product named in answers to "best [category] software" prompts. My own research on 93,968 AI answers found that when a vendor's own listicle was cited, the assistant named that vendor in 45.4% of answers, against 16.3% when it was not (The Search Spot).

We have shifted client budgets in this direction as part of our GEO and AEO work. At D2L, outreach moved from general link building to the third-party roundups that appear as sources in AI answers. Alongside content and monthly refreshes, D2L went from appearing in 12% to 33% of tracked AI answers between December 2025 and September 2026. Demo requests from organic search and LLMs grew 73% in its first year with us. At an enterprise procurement platform, we earned placements on the roundups and industry publications AI assistants use as sources. The brand went from being named in 76% to 88% of ChatGPT category answers in four months.

The best SaaS link building agencies

1. Flying Cat

Flying Cat is the founder-led boutique I run from Los Angeles. I lead the strategy on every account and work with freelance specialists who know each client's vertical. We work in English, French, German, Italian and Spanish.

We sell link building, digital PR and mention placements only inside our full-service SEO programs, never as a standalone service. Links work best when the same team chooses the target pages, builds the content and reads the conversion data. Each month's budget splits between classic links to the pages that need to rank and brand mentions in the sources AI assistants cite for the client's buying prompts. Publisher fees pass through at cost.

We score every paid placement before we buy it. We check how many AI answers cite the page across the client's buying prompts, how often the client already appears in those answers and what the placement costs relative to one average deal. For an AI customer service platform client, one roundup was cited in 33 AI responses across six buying prompts. It appeared in 45% of Copilot answers to the client's category question, where the client itself appeared in 7%. We estimated the client could reach roughly 3 to 4 times its visibility on those prompts if it was picked up in a third to half of the answers citing that page. The placement cost came to about 1% of one average organic deal.

Our published results from programs that included link building show how this works in practice.

• Leapsome. Around 50 targeted links to four priority pages and about 30% growth in referring domains in twelve months. Organic and AI-sourced sales-accepted opportunities grew 48% from the first half to the second half of 2025 (case study).
• D2L. Outreach focused on the roundups AI assistants cite, as part of a program that nearly tripled D2L's share of AI answers (case study).
• Trevor.io. External links went to pages only once they started ranking. Traffic beat the forecast by 402% (case study).
• Softr. Backlinks grew 1,292%. SEO-sourced MRR grew 227% in six months (case study).

Flying Cat fits B2B SaaS teams that want a senior strategist deciding where every link goes. We are a poor fit if you only want a fixed number of links each month without strategy or content.

2. Skale

Skale describes itself as an AI search-first organic growth agency for SaaS. Its link building process starts with a strategy tied to the client's KPIs, then quarterly link targets, prospecting, personalized outreach and long-form guest posts written in-house. Skale also places brand mentions on SaaS review sites and mines competitor backlink profiles for opportunities. The page states that it builds links in English and Spanish only, with about six weeks of outreach ramp-up.

Named clients include G2, Maze, Holded, Slite, Wealthsimple, Bonsai and Lodgify. On its homepage, Skale reports results such as a 450% rise in monthly signups for Holded and a 120% rise in organic signups for Slite. Skale suits SaaS companies that want guest posting and review site coverage run by a SaaS specialist.

3. dofollow.com

dofollow.com states that it works exclusively with B2B SaaS companies. It offers editorial link building, a Visibility+ package that combines links, brand mentions and listicles, and AnswerOS for AI visibility. Logos on its site include Allianz, Surfshark, Experian, Pitch, LegalZoom and Vonage, with case studies for NectarHR and Heymarket.

Pricing is quote-based. Its pricing page says it bills monthly and does not lock clients into long-term contracts. dofollow.com suits SaaS teams that already have a content plan and want a link-only partner.

4. Content Guppy

Content Guppy is a B2B SaaS SEO agency founded by Greg Digneo, who previously led SEO at a bootstrapped SaaS company. Its link building covers DR 60+ link inserts, listicle placements meant to get LLMs to recommend the client, and branded mentions. The agency also books podcast and YouTube appearances.

Named clients include Kickbox, Superhuman, Time Doctor and V2Cloud. Content Guppy reports that Kickbox moved a sales page from position 9 to number one. It also reports that Superhuman reclaimed the top ranking for "inbox zero". It suits smaller SaaS teams that want links pointed at revenue pages.

5. Scalerrs

Scalerrs is a SaaS-only agency founded by Jules Davies. Its services cover SEO, AEO, content, link building from relevant sites, pitches to third-party listicles, Reddit, YouTube and Wikipedia page creation. Clients include Default, Qrvey, Qwilr, Pabau and Morgen. Scalerrs reports that Qrvey grew pipeline from $740K to $1.5M in a year.

Scalerrs lists every service at custom monthly pricing, billed through a monthly subscription. It suits mid-stage SaaS teams that want link building and AI visibility channels handled by one pod.

6. uSERP

uSERP is a Denver-based agency that earns links through content-led placements on large publications, digital PR, guest content and resource pages. It also offers GEO and AEO work and fractional SEO leadership. Logos on its site include monday.com, CrowdStrike, Robinhood, Freshworks and ActiveCampaign, with case studies for Remote, Preply and Hightouch.

Case studies include GatherContent, Lokalise, Smartling and AppSumo. Full-service engagements start at $120,000 per year. Omniscient suits larger SaaS companies that want link building as one part of a content and SEO program.

8. Editorial.Link

Editorial.Link is a link building agency in St. Petersburg, Florida, founded in 2020. It offers editorial backlinks, broken link building, listicle links, brand mentions and digital PR, plus white-label work for agencies. Case studies include Intellias, Belkins, PeopleForce and Skylum.

It publishes per-link pricing of $375 for one link, $1,750 for five and $6,000 for twenty, with premium placements from $550 per link. Editorial.Link suits in-house SEO teams that already know which pages need links.

9. GoPeak

GoPeak builds link insertions, guest posts and brand mentions aimed at AI search visibility. Its FAQ calls it a backlink provider for SaaS companies, though it also serves finance, ecommerce and other industries. Case studies cover Referral Rock, My Hours and Virtalent.

Its off-page work centers on digital PR that earns content-driven brand mentions on authoritative sites, alongside Reddit marketing and Google and AI search strategy. Named clients include ServiceTitan, Sitecore, Docebo, Toggl and Meilisearch.

Minuttia does not publish pricing. It suits technical SaaS products that prefer mentions earned through content and PR over bought placements.

How much SaaS link building costs

The prices below come from each agency's own website in October 2026. I left out agencies that do not publish prices.

At Flying Cat, every program starts with a $5,000 Strategy Launch that takes 3 to 5 weeks. Programs run from $4,000 per month. Full-service programs start at $7,000 per month. Link building inside a program starts at about $3,000 per month.

Per-link prices look cheaper on paper. The comparison changes once you count the time your team spends choosing target pages, writing anchors and checking placements. A retainer that includes strategy suits teams without an in-house SEO lead. Teams with one can compare agencies that work alongside in-house teams. Per-link pricing suits teams that already run that strategy themselves.

SaaS link building agencies and general link building services

A general link building service sells placements across every industry, usually priced by Domain Rating. A SaaS link building agency works from your buyer's journey. It targets the review sites, comparison roundups and category publications your buyers and AI assistants read. It points links at product, comparison and alternatives pages. If you sell to one industry, such as healthcare or legal, a niche agency can also work well. Our list of niche-specific link building agencies covers those options. For PR-led coverage, see our guide to digital PR agencies.

FAQ

How much does a SaaS link building agency cost?

Published prices in this list range from $375 per link to $5,000 per month for managed programs, with full-service engagements at $120,000 per year. Placements on popular SaaS roundups often carry separate publisher fees, so ask how those are billed.

How long does SaaS link building take to show results?

New links usually take several months to show in rankings. Pages that already rank move faster. At Trevor.io, pages reached page one in about a month because external links went only to pages that had started ranking. AI visibility can move within the first two months. D2L's case study notes that clients start to see movement within 60 days.

How many backlinks does a SaaS company need each month?

The right number depends on how many links your competitors' ranking pages have and which pages you want to move. Leapsome needed around 50 links over a year across four priority pages. Pick the pages first, then compare their referring domains with the pages that outrank them.

Do backlinks still help with AI search?

Backlinks still help. Links help your pages rank in Google. ChatGPT, Perplexity and Google AI Mode search the web before many answers, which gives pages that rank more chances to be cited. Brand mentions on the pages AI assistants cite showed a stronger correlation with AI Overview visibility than backlinks in Ahrefs' study of 75,000 brands. A SaaS link building budget should cover both.
