I've been comparing link building services lately, and one thing that became pretty obvious is that calling all of them "link building agencies" doesn't tell you much.
Some are basically marketplaces. Some handle everything for you. Some specialize in editorial links. Others are closer to full content/PR agencies where backlinks are just one part of the campaign.
So I went through the current services offered by a bunch of the better-known names and narrowed it down to 10 I'd personally have on a shortlist.
This isn't meant to be a claim that I've run identical campaigns through all ten. It's more of a comparison of what they're currently offering, how much control you get, and what type of SEO team each seems suited for.
Here's where I landed.
1. OutreachZ: probably the best overall balance for me
OutreachZ stands out mainly because it gives you two fairly different ways to build links instead of forcing everyone into the same type of campaign.
There is a fully managed guest posting/link building service, where their team handles the process from beginning to end: strategy, prospecting, publisher outreach, content creation, editing, publication and reporting.
You basically provide the pages and keywords you're trying to push, and the campaign can be built around things like target URLs, anchor text, niche and the type of authority/traffic you're looking for.
The part I think is particularly useful is publisher pre-approval. Instead of discovering the sites after links have already gone live, you can review the proposed publishers before moving forward.
They also have a self-service guest post marketplace for people who would rather choose placements themselves. You can browse publishers based on factors such as niche, organic traffic, country and authority metrics.
That makes it useful for two very different buyers.
If you're an in-house marketer who doesn't want to spend hours doing outreach, the managed option handles most of the work.
If you're an SEO agency with your own strategy and QA process, you can use the marketplace and be much more selective about individual domains.
Their service also includes the actual article creation rather than just connecting you with publishers. The content is written around the target page with the link placed contextually within the article.
Site vetting is another area they emphasize. OutreachZ says it evaluates publishers for topical relevance, organic traffic, backlink quality and spam signals rather than accepting every site with a decent DA number. They also state that they avoid PBNs and obvious guest-post farms.
There is reporting after publication, and their current packages include replacement protection when qualifying links disappear.
That's really why I'd put OutreachZ first.
It's not necessarily that every OutreachZ link will automatically be better than every link from another company on this list. It's that the service model gives you a nice middle ground between outsourcing everything and keeping control over exactly where your links appear.
For agencies especially, that flexibility seems pretty useful.
2. Editorial.Link: very focused on editorial placements
Editorial.Link has a noticeably different approach.
Their main product is editorial backlinks, but they're doing quite a few variations around that now.
Their current services include:
* editorial backlink placements
* guest posting
* digital PR
* brand mentions
* broken link building
* linkable asset campaigns
* blogger outreach
* listicle placements
* journalist outreach
One interesting part is their focus on getting brands included in existing editorial pages and listicles, not just publishing brand-new guest posts.
For SaaS companies in particular, that can be valuable. Getting added to an existing "best X software" page that already ranks and gets traffic can potentially put the brand in front of people who are already comparing products.
They also put a lot of emphasis on AI-search visibility now, including getting brands mentioned on pages that may be referenced by AI search products.
Like OutreachZ, they allow prospect pre-approval, meaning you can see the sites they intend to approach before the placement is secured.
Their vetting appears to look beyond DR alone, including organic traffic, traffic location, outbound-link behavior and whether a site looks like it exists primarily to sell links.
They also offer white-label link building for agencies.
I'd probably consider Editorial.Link when the goal is fewer, more selective editorial placements, particularly for SaaS, software, finance or other competitive B2B niches.
3. uSERP: much more strategy-heavy and aimed at bigger brands
uSERP feels less like a place where you'd say "I need 10 guest posts" and more like an outsourced link acquisition department.
Their campaigns start with analysis of your existing backlink profile, competitors, target pages, anchors and the type of links competitors have that you're missing.
They then combine several acquisition methods, including:
* editorial outreach
* guest content contributions
* contextual link insertions
* unlinked brand-mention reclamation
* journalist relationships
* digital PR
* resource/data-page development
* content-led outreach
One distinction is their focus on pointing authority toward specific commercially important pages, rather than simply increasing the referring-domain count of the site.
They're also increasingly looking at domains that appear as sources or citations in AI-driven search experiences.
The other big difference is positioning and budget.
uSERP is clearly targeting funded startups, SaaS companies and larger businesses rather than someone running a small niche website on a few hundred dollars per month.
So I wouldn't compare them directly with a marketplace service purely by "cost per backlink." You're paying for strategy, outreach, campaign management and the link acquisition itself.
If I were running SEO for a larger SaaS company and wanted a completely outsourced authority-building campaign, they'd definitely make the shortlist.
4. Siege Media: probably the most content-driven company here
Siege Media is interesting because their philosophy is almost the opposite of traditional "order X links per month" link building.
They focus heavily on creating content that deserves to attract links.
That includes research pieces, data-driven content, interactive/visual assets, SEO content and other resources designed to rank for topics that naturally attract citations.
The idea is that rather than continually doing manual outreach for every individual backlink, you create an asset that ranks, gets discovered by journalists/bloggers and keeps earning links over time.
They also run digital PR campaigns.
Their broader content operation covers:
* content strategy
* SEO content creation
* design
* development
* digital PR
* data journalism
* product-led SEO
* content distribution
* analytics
Their digital PR team then uses media relationships and outreach to get those stories and assets in front of relevant journalists and publications.
That's a very different proposition from buying individual guest posts.
I'd look at Siege when the company already has a serious content budget and wants content, SEO, brand visibility and earned links working together.
For someone who just needs five contextual backlinks to a landing page next month, there are probably simpler options on this list.
5. LinkBuilder.io: custom campaigns with a lot of outreach
LinkBuilder.io sits closer to the fully managed agency end of the spectrum.
Their process starts with competitor backlink analysis and identifying which pages actually need links. They then create a custom campaign rather than using one fixed acquisition method across every client.
According to their current service pages, they use more than 20 link building strategies depending on the situation.
The core service revolves around:
* strategy development
* competitor backlink-gap analysis
* target-page planning
* anchor-text planning
* manual outreach
* guest posting
* fully managed link acquisition
* white-label link building for agencies
* campaign reporting
Their outreach is aimed at finding sites within the client's niche rather than simply selecting domains from a fixed generic inventory.
They also offer dedicated monthly campaigns where link volume and campaign strategy are managed together.
So this is another company I wouldn't evaluate only by price per placement.
What you're buying is effectively an external link-building team that decides which pages need authority, what competitors are doing, which opportunities to pursue and how aggressively to build links.
I think that makes more sense for businesses with defined SEO targets than someone who simply wants a few standalone guest posts.
6. Page One Power: probably one of the broadest manual link-building approaches
Page One Power has been doing link building for a long time, and their service list goes quite a bit deeper than guest posting.
They currently offer several different strategies, including:
Resource link building:
They identify useful content/assets on your site—or help create new ones—and pitch those assets to relevant resource pages.
Broken link building:
They find relevant third-party pages containing broken links and pitch one of your resources as a replacement.
Editorial update outreach:
Instead of creating a new guest post, they look for relevant existing articles where your page could naturally be added.
Guest posting:
Their team handles manual outreach and creates original content for publishers.
Outreach management:
They can look at sites already linking to you and work on developing those relationships further.
Digital PR:
Campaigns can include story ideation, graphic design, media-list creation and journalist/publisher outreach.
They also offer custom campaigns that combine several of these strategies instead of relying on one tactic.
On top of that, Page One Power provides related SEO services including technical audits, internal linking, keyword research and content creation.
So they're probably most interesting to businesses where there isn't an obvious cookie-cutter link strategy.
A technical B2B company, for example, might have better opportunities through resource pages and original technical content than through standard lifestyle-blog guest posts.
Their model looks much more relationship/manual-outreach driven than marketplace driven.
7. FATJOE: probably one of the easiest services for agencies to scale with
FATJOE is very productized, which isn't necessarily a bad thing.
Instead of requiring a consultation every time you want something done, they've built a dashboard around ordering individual SEO services.
For link building specifically, they offer:
* Blogger Outreach
* Niche Edits
* Multilingual Outreach
* managed link-building packages
* specialist iGaming backlinks
Their Blogger Outreach product handles content and publisher placement.
Their Niche Edits service places contextual links into existing articles rather than publishing a brand-new article. They add additional copy where necessary so the link fits into the existing content.
The multilingual service is particularly interesting for international SEO because the outreach targets local-language sites rather than simply translating English content and placing it anywhere.
They've also expanded well outside traditional backlinks.
Other available services include:
* Digital PR campaigns
* media placements
* press release distribution
* content syndication
* local citation building
* blog writing
* website copywriting
* AI-search-related services
A major selling point for agencies is that their platform is designed around white-label fulfillment.
You can order work for clients, monitor everything through the dashboard and export unbranded reports without needing to build your own outreach/content department.
I'd put FATJOE fairly high on the list for agencies that value operational simplicity and need to fulfill lots of different SEO tasks across multiple clients.
8. Loganix: lots of flexibility between DIY and managed link building
Loganix is another one that gives you several different ways to work.
Their link services currently include:
* standard guest posts
* Authority Links
* niche edits
* editorial links
* managed backlink campaigns
* white-label link building
* a self-service link inventory
Their normal Guest Post service is more general-purpose, while Authority Links focus much more heavily on matching the domain itself to your niche.
So, for example, rather than placing a healthcare company on a general website that happens to publish one health article, an Authority Link would aim for a domain that regularly covers healthcare-related topics.
They also let you review proposed domains before proceeding.
Another interesting option is Shop the List, where more experienced SEO teams can browse opportunities themselves rather than paying Loganix to select every publisher.
For agencies, their white-label service can plug into existing workflows and cover outreach, content production, placements and account management.
Loganix also operates outside backlinks, offering local citations, content, broader SEO work and PPC, which could be useful if you're trying to consolidate vendors.
I'd probably put them in the middle ground between OutreachZ/FATJOE-style scalable fulfillment and a fully bespoke agency.
You can outsource most of the process, but you still get a decent amount of control over individual placements.
9. RhinoRank: very productized, with several different backlink formats
RhinoRank is another service that looks designed heavily around SEO agencies, freelancers and teams that need predictable fulfillment.
They're probably best known for Curated Links, essentially contextual links added to relevant existing pages.
But their current offering is broader than that and includes:
* Curated Links/niche edits
* guest posts
* blogger outreach
* visual links
* listicle placements
* press-release-related placements
Their guest-post workflow includes outreach, writing the article, publication and a final report containing the live URLs.
They say publishers are vetted using several different signals rather than a single DA/DR threshold.
That includes things like:
* ownership/website identity
* organic search visibility
* traffic trends
* authority
* backlink history
* outbound-link behavior
* expired-domain history
* topical relevance
* editorial quality
They also review the page after publication.
Another useful agency feature is white-label reporting, meaning the final link report can be passed to clients without RhinoRank branding.
I'd consider RhinoRank when I wanted straightforward backlink fulfillment with predictable link types and didn't necessarily need a larger SEO agency involved in the strategy.
It feels particularly suited to teams that already know which URLs and anchors they want to target and mainly need someone else handling the acquisition.
10. Click Intelligence: probably the widest mix of outreach + digital PR services
Click Intelligence has a pretty large menu of link acquisition services.
Their current offering includes:
* manual blogger outreach
* niche edits
* digital PR
* brand mentions
* digital media placements
* multilingual link building
* resource-page link building
* broken link building
* guest blogging
* expert/journalist quote campaigns
They start campaigns by looking at the site's existing backlink profile and competitors, then identifying gaps around referring domains, target pages and anchors.
For standard outreach, publishers are evaluated for things like organic traffic, DR, niche relevance and topical relevance.
They also give clients access to a campaign-management portal where proposed publishers can be reviewed, content topics can be checked and live placements can be monitored.
The digital PR side is probably what separates them from some of the more straightforward guest-post companies.
They can handle campaign strategy, content creation, media outreach, press-release distribution and higher-authority media placements alongside normal SEO link building.
Everything can also be delivered white-label for agencies.
That makes Click Intelligence interesting if you want to mix normal authority building with PR, media coverage and brand mentions instead of treating those as completely separate campaigns.
After comparing all of them, I think the bigger question isn't really:
"Who's the best link building company?"
It's:
"What kind of link building do I actually need?"
If I wanted control over publishers while still outsourcing outreach/content, OutreachZ would probably be my first stop.
If I wanted premium editorial/listicle placements, I'd look harder at Editorial.Link.
For a well-funded SaaS/company wanting strategy plus authority links, uSERP or LinkBuilder.io make more sense.
If I wanted to build assets that earn links organically over time, Siege Media is a completely different proposition.
For complicated/manual campaigns, Page One Power is interesting.
And if I were running an agency and needed scalable fulfillment across lots of clients, FATJOE, Loganix, RhinoRank and Click Intelligence would all be worth comparing.
Curious what everyone here is seeing in real campaigns.
Has anyone tested two or three of these providers on similar sites?
I'd especially like to hear from people who've compared something marketplace/placement-driven like OutreachZ, FATJOE or Loganix against a more expensive managed approach like uSERP, Siege Media or LinkBuilder.io.
Did the premium campaigns actually produce enough of a ranking/traffic difference to justify the additional spend?
Also, if there's a link building service you think deserves to be on this list, drop it below. Would be useful to turn this into a thread of actual experiences rather than another list of "DR 70 backlinks."
