That risk is especially relevant in SaaS, where the pages worth promoting are often product comparisons, alternatives, integrations, or features aimed at a fairly specific buyer. A good agency should question the target pages before it starts link building.

The seven companies below have different strengths. We looked at their published services, SaaS experience, examples, and the kind of client each seems equipped to help. There's no point pretending a consultant and a full-service SEO agency sell the same thing.

1. Growth Partners Media

Consider Growth Partners Media when a SaaS company has pages with ranking potential but needs a sensible plan to build authority. For example, a comparison page at position 14 might be a better investment than a brand-new guide chasing a keyword dominated by huge software publishers.

GPM no longer prescribes a fixed guest-post versus niche-edit split, after their recent rebrand. An Authority Links campaign might use either, plus expert contributions and other editorial opportunities. It depends on the destination page, existing backlinks, and what publishers can genuinely offer. Sometimes a link from an established article is the smarter choice. Sometimes you need a fresh piece with enough room to explain the product properly.

Quality checks are part of the process too. GPM uses manual 14-point reviews, looks beyond Domain Rating at editorial quality and relevance, and gives clients live placement tracking. Qualifying Authority Links carry a 12-month replacement guarantee. SaaS companies can also run separate Brand Mentions campaigns for visibility in relevant category comparisons and best-of articles.

Cost: Authority Links start at $2,195 a month for five placements, at least two of which come from DR60+ sites. The service makes most sense once you've got commercially useful pages worth backing. If the content itself is weak, you'll want to sort that out before throwing links at it.

2. Heroic Rankings

Heroic Rankings could suit a startup whose marketing team has SEO tasks piling up faster than it can handle them. Alongside link acquisition, the agency can work on content and technical issues. For a team without an in-house SEO specialist, using one provider for all those tasks may be easier to manage.

Its link building offering includes guest posts, niche edits, link exchanges, and directory opportunities. Heroic also covers on-page SEO, research, ecommerce, and local search, and it supports agencies through white-label work. That makes it a fairly versatile partner, even though its client base goes beyond SaaS.

Heroic says it's completed more than 200 campaigns. I'd ask to see two or three live placements from software clients, ideally in a niche with a similar sales cycle. The source articles, landing pages, and anchors will tell you more about the agency's SaaS experience than a headline campaign count.

Heroic is a reasonable choice for a startup without its own SEO team. If you've already got technical and content work covered and only want a small, specialist outreach operation, its broader model may be more than you need.

3. Nine Peaks Media

Nine Peaks Media has a clear advantage for SaaS buyers: software and technology are central to its business. It works with SaaS, cybersecurity, IT, and related companies, and has a dedicated service for SaaS link acquisition.

Its methods include competitor backlink research, guest posts, link insertions, and relationship-based outreach. There's also support for content and technical SEO. That can be useful in software categories where a page needs to explain product capabilities properly before anyone links to it, or before Google has a reason to rank it.

Nine Peaks publishes case studies from tech campaigns. One IoT example reports a 99% increase in organic traffic and a 611% increase in marketing-qualified leads, though that was a wider SEO engagement and the results shouldn't be attributed to backlinks alone.

With Nine Peaks, I'd want examples from a technical SaaS category, preferably links pointing to feature or comparison pages rather than another set of homepage mentions. I'd read the source articles too. You can usually tell quite quickly whether an outreach team understands the subject or has simply found somewhere willing to publish a link.

4. Why Stuff Sucks

Sometimes you don't need another production team. You need someone to look at your target keywords and say, "Why are we spending money on this page?"

That's a good reason to speak to Why Stuff Sucks. Miles Anthony Smith leads the consultancy, which covers link building alongside content, technical SEO, and broader search strategy. His published advice discusses earning relevant backlinks, competitor analysis, and developing content people have a reason to reference.

This approach appeals to SaaS companies with an in-house marketer or SEO specialist who can do the work but wants experienced direction. A consultant can spot a flawed plan before the outreach budget disappears into another month of placements.

I'd settle one point with Miles early on: who actually carries out the outreach? He might develop the plan and review the work while your team handles delivery, or the engagement might include execution. Either setup can work. You just want to know what you're buying before the first month is gone.

5. Omniscient Digital

Omniscient Digital targets a different stage of SaaS growth. Its link building is part of a broader B2B organic marketing operation involving content, technical SEO, analytics, and brand visibility. For a company with an established product and meaningful marketing budget, that can be appealing.

Omniscient says it pursues contextual links from relevant publishers. Its reports show the source URL, anchor, destination page, and domain metrics, and it advertises DR50 as a minimum for qualifying links. I'd request an example report and open a few of those source pages. The numbers are useful, but the surrounding article still needs to make sense.

One of its more interesting ideas is Surround Sound SEO, which pays attention to the third-party articles and comparisons that buyers encounter while researching software. A SaaS business might want to appear in those recommendations even when the immediate value isn't a conventional backlink.

Omniscient publishes a $10,000 monthly starting point for full-service engagements, not necessarily for links alone. I'd discuss it if you're building a substantial organic program. Hiring it for five or six links in isolation would be an odd use of that model.

6. GrowthMate

With GrowthMate, the payment timing is the interesting bit. The agency says it sends its invoice after delivering the month's agreed backlinks. Anyone who's paid a retainer through weeks of vague 'outreach in progress' updates can see why that arrangement appeals. I'd still want the placement standards agreed upfront.

Its focus is B2B, including SaaS publishers and guest contributions, listicle placements, and brand mentions. GrowthMate advertises a DR50 minimum and provides a dashboard for delivered links and campaign performance. It also features testimonials from software-related teams, including Mailtrap and Kompyte by Semrush.

Before signing, I'd ask GrowthMate to define an acceptable placement. Can you reject a site that's mainly there to sell links? Who approves the target URL and anchor? And what happens if a publisher removes the article? Paying after delivery offers some protection, but only if everyone agrees on what delivery means.

GrowthMate makes sense if you want a more defined outreach arrangement and appreciate the pay-after-delivery approach. Request recent placement examples before agreeing on a quota.

7. FHSEOHub

FHSEOHub can be worth considering for SaaS teams that want manual, relevance-first link building without a large monthly retainer. Its services include guest posts, niche edits, listicle placements and other editorial opportunities with an emphasis on getting links to commercially useful pages.

They say they start by reviewing the target pages and existing link profile before outreach begins. Prospects are checked for real organic traffic and topical fit, and clients can approve sites in advance. Reporting includes live links, anchors, and destination URLs, and qualifying placements come with a one-year replacement guarantee. The approach is practical for growing SaaS companies that already have useful products and need clean, contextual links rather than volume.

I’d ask to see a few recent SaaS placements, particularly links pointing to feature, comparison, or integration pages. It’s worth checking the surrounding articles and whether the publishers regularly cover software topics.

FHSEO could be a reasonable option for smaller SaaS teams that already have useful commercial content and want to test an outreach provider before they commit to large campaigns.

Ask the agency to review three actual URLs from your website. Pick a product page, a comparison or alternatives page, and one useful article. Which deserves links first? And which needs better content or internal linking instead? You learn a lot from how a team answers that question.

Then look at some completed placements. Don't stop at DR. Read the page, check what else it links to, and ask whether a potential customer would find the reference natural. A DR80 site publishing unrelated articles stuffed with commercial links isn't automatically a better prospect than a well-run DR50 industry publication.

I'd judge the campaign on more than its delivery sheet. Watch the pages you've asked the agency to support. Are their rankings improving? Are the visitors relevant? Do those pages eventually contribute more trials or demos? Be careful about crediting a single backlink for every improvement, especially if you've also changed the content or site structure.

For a growing B2B SaaS company with strong commercial pages, I'd start by comparing GPM, Heroic Rankings, Nine Peaks and FHSEOHub. If the team needs strategic oversight rather than outsourced production, Why Stuff Sucks is the more natural conversation. Omniscient suits a bigger organic growth brief, while GrowthMate gives buyers a distinct delivery and payment option.

Whatever you choose, the agency should be able to tell you why a particular link belongs on a particular page. That's a better test than an impressive total in a spreadsheet.
