Top 10 SaaS Link
Building Agencies
Top Picks for Every Business
Did you know that 95% of all web pages have zero backlinks?
You might think that’s not a big deal in 2025, but here’s something else to consider: the top-ranking result on Google typically has 3.8× more backlinks than the one right below it.
While editorial backlinks may not get the spotlight they once did, they still play a critical role in boosting your visibility and credibility, especially if you’re in SaaS.
Why does this matter? Because 68% of SaaS buying journeys start with a search engine.
Not convinced? 77% of B2B buyers use search as part of their purchase process, and 27% of the SaaS buying cycle is spent doing online research. You MUST be on top to be noticed and chosen by your potential leads, and there’s no other way out!
And the worst part? Over 80% of B2B buyers end up dissatisfied with their choice, often because of misleading information or unmet expectations.
We get it, and we want to help. That’s why we’ve handpicked the top SaaS link-building agencies to help you cut through the noise and make a confident decision.

The answer is simple. Link building is hard. Really hard!
Over 60% of marketers say it’s the hardest part of SEO. This drives the demand for specialized agencies that bring their expertise and content-driven strategies along with them.
Here’s what you gain by partnering with a SaaS link-building agency:
By working with the right partner, you can scale link-building campaigns without dealing with internal issues, allowing your team to concentrate on growth, strategy, and content.
Choose agencies with a strong history of success. Make sure they follow ethical white-hat methods, provide clear reports, and have knowledge in your specific industry.
The price differs a lot. It can cost anywhere from $100 to over $500 per link. The fees often depend on the link’s quality, the website’s authority, and the agency’s reputation.
Link building shows noticeable SEO gains after a few weeks or even months.
White-hat link building involves earning backlinks through Google-approved and honest techniques. This includes creating good content and reaching out. It avoids tricks or manipulation.
You can handle it on your own, but agencies bring experience, resources, and better scalability, which are hard to achieve when working alone.
People often use guest articles, how-to guides, infographics, or case studies to get meaningful and natural backlinks.
They rely on Domain Authority, website relevance, traffic size, and spam scores to decide if a backlink is useful and trustworthy.
Black-hat link building refers to buying links or using link farms. These actions can hurt your site by triggering penalties from search engines.
There’s no one-size-fits-all when it comes to backlinking agencies. The right choice depends on your goals, budget, and where you are in your growth journey. What works for a lean startup won’t always suit a scaling SaaS brand. And that’s perfectly fine.
Today, SEO is all about quality over quantity. Google’s getting smarter, and the links that drive real results are built on strong content and real relevance. That’s why ethical, content-led link-building remains one of the most effective ways to build authority and drive sustainable growth.
If you're looking for a team that understands SaaS inside and out and can deliver both smart strategy and hands-on execution, Epic Slope could be exactly the partner you need.
