This list is for B2B SaaS founders, marketing leads, SEO managers and solo builders who have decided to pay for link acquisition and want a shortlist they can act on this week. As of 2026, I don't think the choice is whether to outsource. 56% of SEOs outsource at least part of their link building, according to Editorial.Link data from May 2026. The useful question is which kind of partner fits your stage, budget and risk tolerance, and what each one does to your visibility in Google and in AI assistants such as ChatGPT, Claude, Perplexity and Gemini.
I picked these seven resources using four filters. Each one has a public, verifiable track record. Each one earns or places links through a model you can inspect before you sign. Each one fits at least one realistic budget for a growth-stage SaaS company in 2026. And each one helps you build the kind of authority that large language models pick up when they decide which brands to cite. I left out anonymous Fiverr gigs, private blog networks and push-button link packages. Google's spam policies classify buying links for ranking purposes as link spam, and a penalty costs a startup far more than a slow quarter. One entry on this list, Gofylo, is my own product. I include it because it covers the content side that link building depends on, and I describe it on the same terms as everyone else.
The table below gives the short version. Agencies built around editorial content and digital PR suit funded SaaS teams that want links from major publications. Productized vendors and marketplaces suit lean teams that want predictable pricing. Directories and content engines help you find a partner or create the assets that make outreach work in the first place.
| Resource | What it is for | Who it suits |
|---|---|---|
| Siege Media | Content-led SEO and digital PR that earns editorial links | Funded SaaS teams with a content budget |
| Fractl | Data-driven campaigns pitched to major publications | Brands that want press coverage and authority links |
| Page One Power | Custom, relevance-first manual link building | SaaS teams in narrow or technical niches |
| Editorial.Link | Niche edits and editorial placements on established sites | Growth-stage teams that want fast, specific placements |
| FATJOE | Fixed-price blogger outreach and white-label link services | Bootstrapped teams and agencies reselling SEO |
| Semrush Agency Partners | Directory of vetted SEO and link building agencies | Teams that want to compare local or specialist agencies |
| Gofylo (my product) | Autonomous content engine that builds linkable, AI-citable articles | Lean teams that need assets worth linking to |
If you only pick one: start with Page One Power if you have budget for a managed agency, because its relevance-first manual process carries the lowest penalty risk for a young SaaS domain. If you have no content worth linking to yet, fix that first. Outreach for thin pages wastes money with every agency on this list.
Money is flowing into this category fast, which raises both the quality ceiling and the number of low-quality sellers. Link building services were worth about $25.97 billion in 2025, according to linkbuild.agency. In the Reporter Outreach survey of 500 SEO professionals, 58% increased their link building budget in 2026 compared to 2025, and only 14% cut back. The spending appears to pay off for most buyers: 78.1% of SEO professionals report a positive ROI with link building, with results usually appearing within 3 to 6 months.
Siege Media
Siege Media is a content marketing and SEO agency that earns links through the content itself. It builds large linkable assets such as interactive tools, original data studies, visual guides and reference pages. It then promotes them through digital PR and outreach to the journalists and bloggers who cover that topic. The links arrive because a writer needed a source, which is the pattern Google's guidelines describe as editorially placed links. For a B2B SaaS brand, that might mean a benchmark report on pricing models, an industry calculator, or a data-backed explainer that becomes the page other writers cite.
The trade-off is pace and cost structure. An asset-led campaign takes research, design and production before the first link lands, so you are paying for content and promotion together. Teams that judge link building purely on cost per link tend to undervalue this model. Teams that judge it on referring domains earned per asset, and on the organic traffic those assets bring in directly, tend to rate it highly. Referring domains matter here: referring domains correlate 0.255 with Google ranking position across 1 million US keywords, the strongest of the link metrics Ahrefs tested. An asset that keeps attracting new domains for years compounds in a way that a one-off placement does not.
There is also an AI search angle. Assistants such as ChatGPT and Perplexity favor sources that other sources cite, and original data is one of the easiest things for a model to attribute. A Siege-style asset that gets quoted by trade publications puts your brand name next to a specific claim in many places at once. That repeated association is the kind of signal that shows up when a buyer asks an assistant which vendors lead a category.
- Linkable asset strategy built around topics journalists already cover
- In-house design and development for interactive and visual content
- Digital PR outreach tied to each asset launch
- Ongoing SEO content production alongside the link-earning work
- Reporting framed around referring domains and organic traffic to the asset
Best for Funded B2B SaaS companies with a real content budget and a few months of patience. Siege Media fits a marketing lead who wants links and traffic from the same investment, and who can approve a data study or interactive tool as a deliverable. Solo operators and pre-revenue teams will usually find the engagement size larger than they need.
Fractl
Fractl is a data-driven content and digital PR agency. Its campaigns start with a newsworthy question, answer it with a survey, dataset or analysis, and pitch the findings to editors at national and trade publications. The output is press coverage with links, often from sites a SaaS startup could not reach through standard outreach. Fractl has also published its own research on what makes content earn press, which tells you how the team thinks about pitching.
Digital PR differs from placement-based link building in one practical way: you do not control the outcome. A campaign might land coverage on a few dozen sites or on a handful, depending on the news cycle and the strength of the angle. What you get when it works is a burst of high-authority, topically varied links and brand mentions. Some of those mentions will be unlinked. That still has value for AI search, because language models learn brand associations from text, and an unlinked mention in a respected outlet is still a mention.
For B2B SaaS, the trick is finding an angle that is both newsworthy and close to your product. A security startup surveying IT leaders on breach response, or a fintech tool analyzing late-payment patterns, can hand editors a story while keeping the links topically relevant. Campaigns that chase viral consumer angles unrelated to the product earn links that do less for rankings on the terms you sell against. I would ask any digital PR agency, Fractl included, how it ties each campaign back to your commercial topics.
Best for SaaS brands that want authority links and press exposure at the same time, and that have a story or dataset worth telling. It suits a growth-stage company preparing for a funding round or category push, where coverage in major outlets helps sales and recruiting as much as SEO.
Page One Power
Page One Power is a link building agency based in Boise, Idaho, that has focused on manual, custom link acquisition for well over a decade. Its process is relevance-first: the team identifies sites that cover your topic, finds or creates a reason for them to link (a resource page, a contribution, a useful page on your site), and earns each link through individual outreach. It also runs content creation and link reclamation work for clients who need assets to point links at.
Relevance-first matters most for SaaS companies in narrow or technical categories. If you sell observability tooling, procurement software or compliance automation, a link from a mid-sized engineering blog in your niche can do more than a link from a general business site with a higher authority score. Page One Power's approach is built around that kind of judgment. It is slower than buying placements, and it should be. Each link is earned on a site whose readers would plausibly care about your product.
This is also the model I consider safest for a young domain. Google's spam policies define link spam to include, in Google's words, "Buying or selling links for ranking purposes", and they list it among the practices that can lead to lower rankings or removal. You can read the full list in Google's spam policies for web search. Manual, editorial outreach sits on the right side of that line by design.
What to ask a relevance-first agency
Before signing with Page One Power or any similar agency, I would get specific answers to a short set of questions. The answers tell you more than a portfolio of logos.
- How do you define a relevant site for our product, and can you show three examples before the campaign starts?
- Which of our pages will links point to, and do you create new assets if we lack them?
- Do any of your placements involve payment to the site owner?
- How do you report links: live URL, anchor text, referring domain and date?
- What happens if a placement is removed within the first months?
- How do you measure success beyond link count, such as rankings or traffic to target pages?
Best for B2B SaaS teams in technical or specialist niches that want a managed agency with a conservative risk profile. It suits a marketing lead who would rather receive fewer, clearly relevant links than a large monthly count of loosely related ones.
Editorial.Link
Editorial.Link is a link building agency that specializes in placements on established, editorially managed sites, including niche edits (links added to existing articles) and contextual placements in new content. It also runs some of the most cited industry research in this space. Its survey of 518 SEOs found that $8,406 per month is the minimum link building budget SEOs say a highly competitive niche needs, which is a useful anchor when you set your own budget.
Niche edits are fast. A link inside an article that already ranks and already has its own backlinks can start passing value sooner than a link on a brand-new page. The quality question depends on how the placement is obtained. Some vendors in this market pay site owners per link, and you should know the price levels involved. When Ahrefs ran a pricing experiment, the average price for a link on an existing page across 450 sites in nine niches was $361.44. Buyers expect to pay at that level or higher: 76% of buyers will pay $300 or more per link, and 31% are now in the $500–$1,000 range, according to the Reporter Outreach 2026 survey.
Those numbers are why I treat transparency as the deciding factor with any placement-focused agency. Ask how each placement is sourced, ask to see the target site list in advance, and ask whether the pages are indexed and receive organic traffic. A good placement partner will answer all three without hesitation. If you plan to do part of this work yourself, Building B2B SaaS Backlinks through your own outreach uses the same vetting checks, so the questions carry over.
Best for Growth-stage SaaS teams that already have strong pages and want relevant links pointed at them on a predictable schedule. It suits an SEO manager who can vet target sites, approve placements and track each link against the page it supports.
FATJOE
FATJOE is a UK-based outsourced SEO provider known for productized, fixed-price link building. You order blogger outreach placements, guest posts or other services by tier through a dashboard, and the team handles prospecting, content and placement. A large share of its customers are agencies that resell its services white-label to their own clients, which is why its catalog is organized like a menu with clear deliverables.
Productized link building suits teams that need cost certainty more than custom strategy. A bootstrapped founder can budget a fixed number of placements per month and know exactly what will arrive. The trade-off is that you choose from a pool of sites the vendor can place on, rather than having outreach built around your specific niche. For a broad SaaS category such as project management or email marketing, that pool often includes relevant sites. For a deep technical niche, it may not.
Guest posting is the core of most productized catalogs, and the market price of the raw placement is lower than many buyers expect. In the same Ahrefs experiment, paid guest posts averaged $77.80, across 180 sites pitched. A managed service charges more than that because it also covers prospecting, writing, editing and reporting. When you compare productized vendors, compare what is included per tier (content length, site metrics, traffic thresholds, replacement guarantees) instead of the headline price alone.
- Tiered blogger outreach with stated site quality thresholds
- White-label reporting for agencies serving their own clients
- Content writing included in most link packages
- Self-serve ordering through a dashboard
- Related services such as content writing and local SEO
Best for Bootstrapped SaaS founders, solo operators and small agencies that want a fixed monthly link budget with no custom engagement. It works best when your category is broad enough that the vendor's site pool already overlaps with your topic.
Semrush Agency Partners
Semrush Agency Partners is a directory of SEO and digital marketing agencies, run by Semrush, that you can filter by service, location and specialty. Semrush itself is an SEO platform with keyword research, backlink analytics, a backlink audit tool and a link building tool for prospecting and outreach. The agency directory sits on top of that ecosystem. Agencies list their services, and Semrush shows information such as certifications and reviews so you can compare them in one place.
This is the resource I would use to answer the question of which link building companies in the USA, or in a specific city, are worth a call. Instead of trusting a single ranked list, you get a filtered shortlist of agencies by region and service. That matters for teams that want a partner in their own time zone, or that sell into a regional market where local publications carry weight. The directory also covers agencies outside the US, which helps if you sell in several languages.
The directory works best when you pair it with your own backlink data. Before contacting agencies, I would pull your current referring domains and your top competitors' referring domains in Semrush's backlink tools or a similar tool, and identify the gap. That gives you a concrete brief: these are the kinds of sites linking to competitors, and these are the pages we need links for. Agencies that respond to a specific brief with a specific plan are usually the ones worth hiring. How Backlink Automation Actually Works inside platforms like this is worth understanding too, because the same prospecting features can support your in-house outreach between agency engagements.
Best for Marketing leads who want to compare several agencies by location, service and track record before committing. It suits teams that want a US-based or regional partner and teams that already use Semrush for keyword and backlink research.
Gofylo
Gofylo is my own product, so read this entry with that in mind. It is not a link building company and it does not do outreach. It is an autonomous content engine for B2B SaaS and content-driven businesses, and it belongs on this list because every agency above needs one thing from you: pages worth linking to. Gofylo researches keywords from your competitors and the live search results, groups them into topic clusters, writes articles in your brand voice and publishes them to your CMS. On the standard plan that is 30 articles a month, each written in a few minutes.
The link-building connection is practical. Outreach and digital PR convert better when the target page is thorough, cited and clearly useful. Gofylo articles include schema markup, internal links, FAQ blocks, verified source citations and AI-generated images in 5 styles, in 18+ languages. Internal links spread the authority that external links bring in, so a backlink to one article also strengthens related pages in the same topic cluster. That is the compounding effect agencies rely on, and it only happens when your site has enough interlinked depth to receive it.
How the content engine connects to link building
The platform also covers what happens after links arrive. The Search Console refresh rewrites published articles that sit just off page one, using your Google Search Console data, and keeps the earlier version so you can restore it. Those pages are often the ones where a handful of new links would tip them into the top results, so the refresh pairs well with an agency campaign aimed at the same URLs. On the AI side, every article is formatted to be cited by assistants such as ChatGPT, Claude, Perplexity and Gemini, and the AI Visibility Score shows how ChatGPT and Claude see your brand.
- 30 SEO articles a month on the standard plan, published straight to your CMS
- Publishing to WordPress, WordPress.com, Webflow, Shopify, Wix, Notion, Ghost and Framer, plus a webhook
- Search Console refresh with restorable earlier versions
- AI Visibility Score for how ChatGPT and Claude see your brand
- Free AI Search Grader as a standalone starting point
- Single plan at $79/month with a 3-day free trial and cancellation at any time
Gofylo competes with other content platforms such as Writesonic, Outrank and Clearscope, each of which approaches content creation or optimization differently. It does not replace any agency on this list. The way I would use it: let Gofylo build the topical depth and AI-citable pages, then hire an agency to point links at the pages that matter most commercially.
Best for Lean B2B SaaS teams, founders and solo operators who know they need links but do not yet have enough strong content for outreach to succeed. It also suits growth-stage teams that already pay an agency and want more linkable pages without hiring writers.
A simple sequencing rule for 2026: build the pages, then buy the promotion. Agencies can only earn links to content that deserves them, and AI assistants can only cite pages that answer a question clearly. Teams that reverse the order usually pay twice.
Frequently Asked Questions
These are the questions I hear most from SaaS teams choosing among the best link building companies and related resources.
Who are the top 10 SEO experts in the USA?
No objective ranking of individual SEO experts exists, and any top 10 list reflects the author's taste. Widely followed US-based practitioners include Rand Fishkin, co-founder of Moz and SparkToro, and Lily Ray, known for her work on Google algorithm updates and E-E-A-T. For hiring, judge an expert by documented client results and public work, not by list placement.
What do link builders do?
Link builders find websites that cover your topic, give those sites a reason to link to your pages, and secure the link through outreach, content contributions, digital PR or link reclamation. Good ones also choose which of your pages should receive links and report each live link with its URL and anchor text. Their goal is more relevant referring domains, which improves rankings and the chance AI assistants associate your brand with your category.
What is a good SEO company?
A good SEO company explains its methods in detail, shows examples of placements or campaigns before you sign, and reports results tied to rankings and traffic. It never guarantees specific positions and is open about whether any links are paid. For SaaS, it should also understand your product well enough to pick relevant sites and topics.
Who is the best online marketing company?
There is no single best online marketing company, because the right partner depends on your channel, budget and stage. For link building specifically, content-led agencies like Siege Media and Fractl suit funded brands, while productized vendors like FATJOE suit lean teams. Shortlist by the outcome you need, then compare a few providers on the same brief.
What are the best link building companies in the USA?
On this list, Siege Media, Fractl and Page One Power are US-based link building and digital PR agencies with long public track records. To compare more options by city or specialty, the Semrush Agency Partners directory lets you filter agencies by location and service. Ask each one for sample placements in your niche before deciding.
How much should a SaaS startup budget for link building?
It depends on how competitive your niche is. Editorial.Link's survey of 518 SEOs put the minimum for a highly competitive niche at $8,406 per month, while many startups begin with a smaller productized package and scale once content is ready. Spend on content first if your site lacks pages worth linking to.
Before you sign with any of the best link building companies on this list, make sure your site has pages that deserve the links.
