Choosing a SaaS link building agency is harder than the sales decks make it look. Almost every proposal uses the same three promises: relevant sites, better rankings, more traffic.

Those promises are not the brief. The brief is whether the agency can get your product mentioned on pages your buyers already read – comparison articles, integration write-ups, category roundups, research posts – without stuffing a link into a paragraph that has nothing to do with the software.

The details that actually separate vendors:

• Who picks the pages you promote?
• Can you reject a domain before anything goes live?
• Do they understand your category, or just “SaaS” as a keyword?
• Will the report show the published URL, the surrounding copy, and the reason the link exists?

This guide compares 15 providers, from outreach shops to full SaaS SEO partners. Use it to build a shortlist. Then send the same brief to each of them and ask for examples in your category- not a generic “DR 60 guest post” screenshot.

Disclosure: Outreach Monks publishes this guide and appears in the list. The write-ups are based on each provider’s public service pages. We have not run a paid trial with every agency here. Suggested fits are editorial judgments. The order is not an independently measured performance ranking.

Snapshot: what each agency is actually for

An agency that works well for an in-house SEO lead can be a poor fit for a founder who still needs someone to decide which pages deserve links. Start with the job, not the logo.

Confirm scope, availability, and contract terms on the live service pages before you buy. Public pages go stale.

How to use this comparison

We looked at advertised focus and services – enough to tell you what to investigate, not enough to crown a winner for your domain.

When the proposals come back, score every agency on the same five questions:

1. Audience fit. Can they name publications your buyers already trust?
2. Page selection. Can they explain why this URL deserves outreach instead of a random blog post?
3. Quality bar. What makes a site or placement a no?
4. Visibility. What do you approve, and what shows up in the report?
5. Commercial terms. What is included, and what happens if a link drops or misses the brief?

We left off star ratings and unverified price ranges on purpose. A $99 insertion and a $8,000/month SEO retainer are not the same product. Comparing headline prices without scope is how teams pick the wrong partner.

The agencies

1. Outreach Monks

Best used for: SaaS outreach and white-label fulfillment.

Outreach Monks sells a dedicated SaaS backlink service plus guest posts, insertions, managed campaigns, and white-label delivery. Pricing on the SaaS side is typically framed by domain metrics and monthly volume.

This is a practical option if you already know which pages you want to push – product, comparison, integration, alternatives – and you need someone to run the outreach. Agencies can also run delivery under their own brand.

Do not buy a package off a Domain Rating number alone. Open with product category, target countries, and the URLs that actually affect pipeline. Ask for live examples that match that brief.

Ask before you hire: publisher criteria, approval steps, reporting format, and replacement terms for this service – not the generic sales deck.

2. SayNine

Best used for: link building, with other search services on the same roster.

SayNine sells backlinks alongside SEO and AI-visibility work. The public pitch leans on relevant placements, turnaround, and partner relationships.

Worth a look if you want one vendor in the room for both acquisition and a wider search brief. Keep the deliverables separate in the contract. A live backlink, a brand mention, and an observed citation in ChatGPT or AI Overviews are three different outcomes. If they get bundled into one “AI SEO” line item, you will not know what you paid for.

Ask before you hire: what the link-building fee actually covers, and how any AI-visibility work will be measured (query set, platform, location, date).

3. Outreach Desk

Best used for: publisher outreach tied to specific SaaS pages.

Outreach Desk’s SaaS offering talks about tech, B2B, and software publications, and about targeting product, feature, comparison, and demo pages. Reporting is described around live URLs, anchors, and publisher metrics.

That page-first framing is useful. On the first call, hand them three candidate URLs and ask which they would promote, which they would send back for content work, and why an editor would reference each one. If they cannot answer without hiding behind DR, keep shopping.

Ask before you hire: what you can review before publication, and what happens when a placement misses the agreed criteria.

4. Jeenam Infotech

Best used for: a provider that positions itself as SaaS-only.

Jeenam markets itself as a specialist helping software companies earn links through content and outreach. “We do SaaS” is a starting point, not proof.

Marketing automation, cybersecurity, clinical software, and vertical SaaS do not share publishers. A site that is perfect for a CRM tool can be noise for a HIPAA-sensitive product. Ask for examples in your category and market, not a mixed SaaS collage.

Ask before you hire: how publisher research changes for your specific product category.

5. Skale

Best used for: a wider SaaS growth program, not a standalone link order.

Skale sells SaaS SEO, content, link building, and AI search work, and talks about qualified leads, pipeline, and revenue rather than link counts.

Shortlist them if you still need help deciding what to publish and promote – not just who to email. Then interrogate scope. Strategy, writing, technical SEO, and outreach consume different people. A retainer that “includes everything” often means links get squeezed when content production overruns.

Ask before you hire: how they isolate link building’s contribution to pipeline, and how they account for content launches and paid campaigns running at the same time.

6. SaaSLinkBuilder

Best used for: outreach aimed at software-adjacent audiences.

The public process starts with the client’s marketing strategy, then moves into targeted outreach to SaaS publishers with audience overlap. That is the right sequence.

The risk is treating “SaaS” as one audience. Two tools can both be software and still sell to completely different buyers. Ask them to show overlap: topics, job titles, and markets – not just that the referring domain has “SaaS” in a category tag.

Ask before you hire: a written explanation of how a proposed publisher overlaps with your audience.

7. ZeroAdo

Best used for: link building inside a broader marketing engagement.

ZeroAdo advertises digital marketing that includes SEO, content, AI optimization, and links. One partner can reduce vendor sprawl. It can also bury link building inside a vague monthly retainer.

If you go this route, force a split in the statement of work: who owns content, who owns outreach, who ships site changes, and what share of the budget is actually for links.

Ask before you hire: the monthly link-building work, in writing, and the budget attached to it.

8. GrowPad

Best used for: SaaS link building attached to a search plan.

GrowPad’s SaaS service covers profile analysis, outreach, digital PR, comparison placements, and internal linking notes. It also advertises outreach for mentions on sources that show up in AI answers.

Useful when you need someone to find gaps before they start pitching. Get clarity on who implements the recommendations. An internal-linking suggestion that sits in a slide deck does not help the page.

Ask before you hire: how they separate delivered links and mentions from later changes in search visibility.

9. Epic Slope

Best used for: B2B SaaS outreach.

Epic Slope sells link building for B2B SaaS and positions the rest of the business around B2B software and AI companies.

Bring a concrete problem to the first meeting: a new category page with no referring domains, a feature launch, a comparison URL losing to two incumbents. Ask what month one looks like for that problem. Vague “we build authority” answers are a pass.

Ask before you hire: first-month deliverables, plus examples that resemble your brief.

10. B2BSEO.io

Best used for: links that support how B2B buyers actually research software.

B2BSEO.io folds SaaS link building into a wider B2B SEO offer: relevant publications, expert mentions, partner content, product-led assets.

The useful conversation is which asset they would promote first, and why. An integration guide, a comparison page, and an original study each give an editor a different reason to link. If the plan is “we’ll get DR 50+ links to the homepage,” you are not talking about B2B buying behavior.

Ask before you hire: which assets they would push first, mapped to how customers evaluate you.

11. LeadWalnut

Best used for: a bounded project, or SEO plus conversion work.

LeadWalnut works with B2B technology companies on SEO and CRO, and advertises a four-week backlink sprint. A short engagement is a clean way to test research quality and communication before a longer retainer.

Do not confuse sprint delivery with ranking impact. Four weeks is enough to judge process. It is rarely enough to judge organic pipeline.

Ask before you hire: exactly what ships during the sprint, and what monitoring continues after it ends.

12. Genesis Edge Marketing

Best used for: page planning plus manual outreach.

Genesis Edge describes target-page strategy, publisher research, outreach, editorial coordination, and quality review. That is the workflow a SaaS team should demand even when a vendor does not advertise it this cleanly.

Ask them to walk a live example: which of your URLs they would pick, which publishers they would approach, and which placements they would reject. Then ask to see how those checks appear in the final report. Quality review that never shows up in reporting is just copy.

Ask before you hire: a sample quality review and how the report documents it.

13. GetProLinks

Best used for: editorial placements with a paper trail.

Get Pro Links leans on editor relationships and reporting that includes the live URL, target page, anchor, and metrics.

Inspect the article, not just the metrics row. You should be able to open the published piece and see why your page belongs in that paragraph. If relevance only exists at domain level – “it’s a tech blog” – the link is weaker than the spreadsheet suggests.

Ask before you hire: approval and replacement terms, and how they judge relevance beyond DR / DA.

14.The HOTH

Best used for: choosing a format from a large product menu.

The HOTH sells several link products (outreach, insertions, editorial placements, managed options) and a wider SEO / AI-search range.

For a SaaS buyer, the SKU matters more than the brand. “We used The HOTH” can mean very different things. Ask for examples from the specific product you would buy, in a software category close to yours. Also ask how much publisher selection still sits on your team.

Ask before you hire: which product matches this brief, and which planning work you still own.

15. FatJoe

Best used for: white-label execution when strategy already exists.

FatJoe is explicit that agencies with a plan are a strong fit, and it also sells a managed link-building product. That honesty is useful. A fulfillment engine and a strategist are not the same hire.

A small SaaS team with no page priorities will need more than order-and-deliver. An agency that already has target URLs and anchor rules may only need capacity.

Ask before you hire: which decisions the service makes, and which stay with you.

What “relevant” actually means for SaaS links

Start with the reader. Would someone on that page have a reason to click through to your URL?

A guide on reducing no-show appointments can reasonably mention scheduling software or cite research on reminders. The same product dropped into a lifestyle listicle is a different object. Google may still count the link. Your buyer will not.

When a vendor sends a prospect list, open the article and check:

• What the site usually covers, and who it is for
• Whether the piece itself is worth reading
• Whether the paragraph around the link has anything to do with your page
• Traffic and visibility trends, with the usual caveat that third-party tools estimate
• Whether anyone at the publication appears to edit

Domain Rating is an Ahrefs metric. It is useful for first-pass filtering. It is not a Google score, and it does not tell you if the article is a good place for your product. Read the page.

How to compare prices without getting played

Ask every shortlisted agency for a written scope. Cheap is often “less work.” Expensive is sometimes “work you already do in-house.”

Paying an agency to research and pitch editors is not the same as paying a publisher for a ranking link. Google treats buying or selling links to manipulate rankings as link spam. Paid or sponsored placements should be disclosed with rel=”sponsored” or rel=”nofollow”. Ask every vendor how they handle that line. If the answer is slippery, that is the answer.

How to measure the work

Set a baseline before the first pitch goes out: target URLs, the queries that matter, organic clicks, and conversions you actually care about- trials, demos, sales-qualified signups.

Then split reporting in two:

• Delivery. Did the agreed placements go live, and did they meet the quality bar?
• Performance. What moved on those pages and in the pipeline?

Track other changes in the same window. If you rewrite the landing page, fix internal links, and buy a content burst in the same quarter, you do not get to give link building all the credit. A good report says so, then tells you what to try next.

Will link building get you into AI answers?

Relevant coverage puts your brand on more pages that people – and retrieval systems – can find. That is not the same as a guaranteed citation in Google’s AI experiences, ChatGPT, or Perplexity.

Google’s own guidance for AI search still comes back to distinctive, useful content and ordinary SEO fundamentals. There is no published formula where N backlinks equal an AI mention.

If an agency sells “AI visibility,” make them define the queries, platforms, locations, and observation dates. Log a placed mention and an observed AI citation as two different rows. Mixing them is how vendors invent results.

How to choose

Shortlist two or three shops against the job you need done.

• Strategy and content already exist → judge outreach quality, communication, and delivery.
• You are still guessing which pages to promote → prioritize teams that can show research, not just inventory.
• Several parts of marketing are broken → compare broader retainers only if responsibilities are itemized.

Send every shortlist the same brief. Ask for category-relevant examples, a sample report, written quality criteria, and the full commercial terms. The proposal that is easiest to interrogate usually beats the one that sounds most sure of itself.

If you want to talk to Outreach Monks, send the site, product category, target market, and priority pages. That is enough to scope outreach. It is not enough to promise rankings.
