Your best pages aren't ranking, and the gap looks like links rather than content. Link building agencies for B2B and SaaS brands close it in different ways: some sell links one at a time, some sell monthly packages, and some fold links into content and AI-visibility work. Choose by how you want to pay and how much control you want. Ten firms follow, unranked.
Ten link building firms side by side

Each link firm in its own words
Page One Power
Boise, Idaho is where this firm started, according to its About page. Its site describes custom link building across several link types, with digital PR campaigns and some on-page and technical SEO alongside. It says it has only ever done link building, builds custom campaigns rather than chasing a link count, and openly says it isn't the cheapest option. Its case studies page shows work for Domotz, a network-monitoring SaaS.
Foundation Marketing
Philadelphia is home to this one, going by the address in its site footer. It calls itself an outcome agency, and the outcome it names is visibility in AI search, built through digital PR, thought leadership, generative engine optimisation, technical SEO, Reddit marketing and content distribution. Links are one ingredient in that mix rather than the product. It lists B2B tech, SaaS, AI, martech, cybersecurity and developer tools among the sectors it serves, and its case studies include Bitly.
Quoleady
Software companies are the stated audience here. Its site describes manually built dofollow links, placed by writers who publish on third-party platforms, plus three-way link exchanges with SaaS blogs, all inside a wider SaaS content and AI-visibility offer. Payment is performance-based for live links only, it says, but there's a minimum monthly budget and the first month is paid upfront. A New York phone number is listed, though no head office city is given.
Editorial.Link
Based in St. Petersburg, Florida, with the address in its footer, this agency says it's built for AI search. Before you commit it offers a trial link, and once a campaign starts you see and approve prospect sites before they go in. It says it refuses sites that sell links, replaces lost links within a stated window at no cost, and offers a white-label option. Its About page points to a boutique-sized team.
LinkBuilder.io
Two offices are listed: Edinburgh in the UK and St. Petersburg, Florida. It describes itself as a bespoke white-hat agency that uses outreach to niche-relevant sites, aims for high-relevance links to key pages and gives clients a reporting dashboard. It says it works from a custom process drawing on many link strategies, and serves ambitious brands and agencies internationally, the USA included. It's one of the few on this page that publishes monthly package prices.
Rhino Rank
UK and US phone lines appear on this site, though not a head office city. Its menu runs from curated links inside existing pages to visual links, listicle placements, press releases and articles written for other sites, plus a managed service. The pitch is choice: order the exact links you need yourself, or hand the whole campaign to a dedicated strategist. It says it serves businesses and SEO agencies, and its About page describes a mid-sized staff.
Digitaloft
From offices in Kendal and Manchester, this team offers digital PR, SEO, content, technical SEO and GEO to earn links and search visibility. It says it only does SEO and rejects vanity metrics in favour of commercial impact, aiming at searches made by people ready to buy. Published case studies include a business-travel brand, a Christmas-tree retailer and a lead-generation firm, and its site shows work for Booking.com for Business.
Siege Media
US offices in Austin, New York City, Chicago and San Francisco sit behind this agency. Its digital PR page lives beside content marketing, research reports, Reddit and affiliate partnerships, and AI-search content, and it ties link earning to that content and research rather than selling links alone. Industries listed on its site include SaaS, e-commerce, travel, education, cybersecurity and real estate, and its site shows work for Mentimeter.
LinkDoctor
Editorial link placements are the core offer, delivered through a staged process it labels discover, strategise, create and connect, then earn and report. It says it reports every outcome and pitches one strategy aimed at both Google rankings and citations inside AI answers. Testimonials on its site come from a B2B industrial-software firm and a consumer brand, and its About page names Industrial Defender as a client. No office location is given.
Outreach Monks
Agencies and SEO professionals are the main audience, with brands welcome too, and everything it sells is white-label. The list covers articles placed on other sites, niche edits and other manual link work, plus AI brand mentions, ordered per link or as a managed service. It states plainly that it uses no PBNs and writes placed articles in-house, and its site describes a large in-house team. Stated delivery times are on its site.
Three working models behind the ten
The first group is the link-only specialists. Page One Power, Editorial.Link, LinkBuilder.io and LinkDoctor all put links at the centre of what they sell, and they differ mainly in how much say you get over target sites and how they report. If you already know which pages need authority, this is the most direct route.
The second group treats links as a by-product of content and AI visibility. Foundation Marketing, Quoleady, Siege Media and Digitaloft each wrap link earning inside research, PR, content or GEO work. That suits a brand that wants to be cited and talked about, not only linked to, and it pairs naturally with running digital PR alongside your SEO.
Want AI doing the heavy lifting in your marketing?
I build the systems that handle the boring 80 percent, so you get your week back. Done properly, with the human kept in.
The third group runs more like an ordering desk. Rhino Rank and Outreach Monks let you buy specific link types, often white-label, with a managed option on top. It suits agencies more than brands without an SEO lead.
How to vet a link builder's pricing model before signing
Here's the part most buyers miss. The pricing models in this group are nothing alike. One firm publishes a per-link base rate, another sells monthly link packages, and a third bills only for live links yet still sets a monthly minimum and asks for the first month upfront. None of those is wrong, but they shift risk in very different directions, so compare the model before you compare the total.
- Am I paying per link, per month, or per live link, and what happens to money already paid if a link never goes live?
- Do I see and approve each target site before outreach, or only after the link exists?
- Is there a minimum spend or minimum term, and is any part of it paid upfront?
- What do you do if a link disappears a few months later?
- Which of my pages will the links point to, and who decided that?
- What does a monthly report show: links, rankings, traffic, or mentions in AI answers?
I'd also ask each firm to describe a campaign that didn't go to plan and what it changed afterwards. The answer tells you more about how it works than any case study.
What to gather before your first call with a link team
Go in with a short list of the pages you most want to rank, the search terms behind them and any links you've earned so far. If you've never mapped where links fit in your wider search plan, this guide to link building for SEO is a useful starting point. Know your budget range, how long you can commit and who on your side signs off target sites. A firm that can't work with those answers early is unlikely to work well with them later.

Frequently asked questions
How much do link building agencies charge?
Costs vary widely and depend on the model: per link, monthly package, or a monthly minimum billed on live links. Compare what's included, such as site approval and replacement of lost links, not just the headline figure.
Is it safe to hire a link building agency?
It depends on how the agency finds and places links. Ask whether you can approve target sites, whether it refuses sites that sell links and how it reports.
What's the difference between link building and digital PR?
Link building usually means outreach for a placement on a specific page or site. Digital PR creates a story, study or asset and pitches it to journalists, with links as a result of the coverage. Several firms on this list offer both.
How long before links make a difference?
Links tend to take months rather than weeks to show up in rankings, and results vary by how competitive your terms are.
Should a SaaS company use a SaaS-only link builder?
A specialist knows which software blogs and review-style sites matter in your niche, which can save time. A generalist may bring a wider spread of sites. Ask both for examples in your category before you decide.
Can an agency resell link building under its own brand?
Yes. Several providers here offer white-label options, so an agency can deliver links to its own clients under its own name.
