The Top 10 Link Building Agencies in 2025

Effective link building is a cornerstone of SEO but it can be time-consuming and challenging for businesses to manage in-house. So much so that even many SEO agencies outsource it to dedicated agencies that provide white-label link-building

This is where professional link-building agencies come in. These agencies specialize in acquiring high-quality backlinks helping websites improve their search engine rankings and online visibility.

Here is a list of the best of them.

1. Very Fine Links

That’s us. Starting an agency was never part of the plan. All we wanted was quality links for our businesses and projects. However, outsourcing link-building to freelancers and agencies left us with few results. And lots of frustration.

Long story short, we learned and mastered the art of link-building – the hard way. And we created a dedicated agency committed to providing the same level of care and focus in link building that we applied to our past clients and projects.

😀 We like: high experience at a discount. We’re new as an agency but we are far from new in the link-building games.

☹️ We don’t like: the beginning is always the hardest. As a new agency, we don’t yet have a portfolio full of case studies or a long list of glowing reviews – but we’re getting there.

2. LinkBuilder.io

LinkBuilder.io, established in 2016, has built a reputation for delivering effective link-building strategies tailored to each client’s unique needs. They have collaborated with notable companies such as Udemy, SoFi, and SnackNation, showcasing a portfolio with clients from diverse industries.

LinkBuilder.io has transparent processes and measurable results. With a focus on personalized strategies and a commitment to white-hat practices following Google’s best practices, this link-building agency stands out as a dedicated partner for businesses aiming to enhance their online presence through high-quality link-building services

👍 We like: their website. It’s the most well-designed in the industry by miles.

👎 We don’t like: their pricing. Starting at 2,999/ mo with just 8 links, it’s on the expensive end.

3. The Hoth

The HOTH is one of the oldest link-building agencies in the market. Founded in 2010,  it has been offering its services since then to businesses of all shapes and sizes and has grown into a key player in the SEO world.

The HOTH offers more SEO-related services than just link-building. Accordingly, it offers blog content creation, website content writing, and technical SEO. They also offer free SEO tools, such as the Google Rank Checker and Backlink Checker, leveraging APIs from well-known SEO platforms.

👍 We like:  The HOTH has the highest organic traffic of any agency on this list. This is a testament to their organic search skills.

👎 We don’t like: An agency of The HOTH’s size is inevitably geared toward offering standardized, off-the-shelf services rather than tailor-made solutions and unique angles.

4. Dofollow.com

Dofollow.com focuses on delivering high-quality, niche-relevant backlinks. They pride themselves on taking a completely manual approach, with high editorial standards, and avoiding black hat link building for better results.

Dofollow.com services and clientele are pretty specific: link bulbing services (no content, no technical SEO) for B2B SaaS companies. Every client that starts collaborating with Dofollow also gets a dedicated project manager.

👍 We like: Dedicated B2B SaaS agency. Laser-focused services usually come with a high expertise (and possibly an equally high pricing – read below).

👎 We don’t like: Non-transparent pricing. Although they mention “Choose a budget that works for you”, they offer no point of reference whatsoever.

5. UK Linkology

As the name gives away, UK Linkology is a UK-based link-building agency. It has been serving clients globally for over a decade, providing high-quality backlinks through a variety of services, including link-building campaigns, international link-building, and niche edits.

The agency employs a proprietary strategy & formula, called the M-Flux V2 formula that is meant to ensure the selection of impactful sites for link placement. Furthermore, UK Linkology maintains a vast inventory of vetted publishers, enabling them to cater to both English-speaking and international markets.

👍 We like: gambling and iGaming link-building services. A nuanced industry that most other agencies try to stay away from, especially when it comes to SEO.

👎 We don’t like: the whole M-Flux thing. It may be useful, eventually, but one shouldn’t have to try to comprehend a custom-made formula to decipher the pricing.

6. Stan Ventures

An Indo-American SEO agency, Stan Ventures provides scalable link-building services for global businesses, focusing on outreach-driven campaigns that generate natural backlinks. They cater to a wide range of industries, from Law to Travel.

Their emphasis on adaptability and client-focused strategies makes Stan Ventures a versatile choice for businesses of all sizes. Whether you need niche edits, blogger outreach, or a comprehensive link-building campaign, Stan Ventures provides the whole link-building services spectrum.

👍 We like: value for money. They achieve that by combining native US content writers with technologically savvy and affordable SEO talent from India.

👎 We don’t like: pricing starting from $49/ link. These kinds of cheap and counter-productive links usually do more harm than good – not only for the client but the link-building industry as a whole, too.

7. Page One Power

Founded in 2010, Page One Power has established itself as a leading link-building agency. They specialize in creating customized, sustainable link-building strategies and high-quality content to enhance clients’ search traffic and rankings.

What’s more, the link-building agency also offers content marketing services, technical SEO audit, and Digital PR, covering most SEO needs for most companies.

👍 We like: its up-to-date Blog. A wide range of well-written topics, from how to measure a Digital PR campaign to frequent industry reports.

👎 We don’t like: no transparent pricing. Having to give your business email to get a non-custom quote is a no-go for us.

8. The Upper Ranks

The Upper Ranks is a specialized link-building agency dedicated solely to enhancing clients’ search engine visibility through high-quality backlinks. Over the past 14 years, they have refined their services to become a trusted partner for SEO agencies, publicly traded companies, Silicon Valley startups, and in-house SEO teams. 

According to the agency, The Upper Ranks are trusted by some high-profile companies and brands, including eBay, Microsoft, Outdoorsy, and Neil Patel, among others. In total, they have worked with more than 1,500 clients and keep on building more than 30,000 links each year.

👍 We like: the clients it’s worked with. Not many link-building agencies can do a name-dropping of this level.

👎 We don’t like: the lack of any case study on their website, despite their long presence in link-building and SEO. Also, no transparent pricing.

9. Outreach Monks

Another link-building agency that has stood the test of time, Outreach Monks prides itself on manual outreach processes and guest posts written by experienced native writers. According to the agency, it has offered its link-building services to more than 2,000 businesses and agencies all across the world

Naturally, Outrach Monks focuses on delivering high-quality, editorial backlinks from authoritative sites. They also cater to niche industries, including cannabis and casino, as well as country-specific link-building strategies for localized SEO.

👍 We like: providing services for niches such as iGaming, Casino, and CBD. A difficult service to provide, given it’s done right of course.

👎 We don’t like: link-building placement starting from $79/ link. In the long term, these links often cause more harm than good – not just for the client but also for the overall reputation of the SEO industry and link-building services.

10. BatLinks

A small group of enthusiastic young professionals from different backgrounds share a love for link-building, content creation, and marketing. Batlinks offers niche-specific SEO services, with a particular emphasis on the catering and eCommerce industries.

Their link-building services encompass guest posts, link insertions, three-way link exchanges, backlink packages, and broken link building. Additionally, BatLinks provides content marketing and link-building consultancy services.

👍 We like: its Services analysis. They try to educate their potential clients, striking a good balance between being technical and accessible. 

👎 We don’t like: a new agency. In contrast to most agencies in this list, BatLinks is a new agency with not many opportunities to showcase its expertise and results.

Conclusion

SEO is considered one of the less transparent digital marketing branches – and link-building less transparent part of SEO. In other words, choosing an agency for your link-building needs needs more research than other services.

If we were to choose a link-building agency, at the end of the end we’d consider these factors:

  • Price
  • Services
  • Case studies
  • Client reviews
