Short answer: SEO Engico is the top pick among link building services for agencies that want trade rates in writing and links they can defend: wholesale from $145, every site vetted by its own team and reports ready to forward. Outreach Monks suits agencies placing bulk multi-client orders, Vazoola suits tight budgets, and Reporter Outreach lets you resell journalist-earned coverage under your own brand.
Most agencies that sell SEO end up selling links, and very few want to run an outreach team to deliver them. Link building services for agencies fill that gap: a specialist builds the links, you sell and report them, and the client relationship stays yours. The hard part is choosing a partner whose links you would put your own name to, at a price that still leaves you a margin.
This list ranks providers that sell link building to agencies as a defined service, checked against their own sites in November 2026. Marketplaces and self-serve directories are left out. Each entry is judged on how it fits the way an agency actually runs: whether you can test it before a client depends on it, how it bills you, whether it handles many clients at once, who approves the sites, what the reports look like and how it keeps out of your client's inbox.

How we picked
- Lets you test before a client depends on it. A trial order, a sample publisher list or a small first batch tells you more than any sales call. Run it on your own site or a friendly client before you put a retainer on the line.
- Bills you at a rate you can mark up. Published trade rates or an agreed agency rate make proposals easy to price. Check that invoices come to you, carry no supplier branding your client might see, and leave room for your margin.
- Handles many clients in one go. Agencies order for ten clients at once, not one. Look for bulk order sheets, per-client tracking and checks that stop two clients landing on the same site.
- Fits your approval process. Decide who signs off sites: you, your client or the provider. Some services build approval in, some charge for it, some skip it for speed. Pick the one that matches what you promised the client.
- Sends reports your team can explain. Every link should arrive with its live URL, anchor, target page and date, unbranded and ready to forward. If your account manager cannot explain a placement to a client, it is the wrong report.
- Has room for your busy months. Client demand is lumpy. Volume tiers, dedicated capacity or month-to-month plans let you scale up for a launch and back down after without renegotiating.
The 7 best link building services for agencies in 2026
Our top pick
1. SEO Engico
- Best for
- Agencies that need links they can put their own name to, at a resale margin
- Based in
- London, UK
- Founded
- 2018
SEO Engico is a London SEO and link building agency founded in 2018, and most of its link volume is white label. The trade maths is published: $145 a link wholesale with a ten link minimum and no monthly commitment, $120 from 20 links a month and $105 from 40. Your brand goes on every report, its team never contacts your client, and reports are formatted to forward without edits. It also does white-label SEO, website builds and technical fixes for agencies and consultants, so an agency can hand more than links to the same team.
The links are built the same way as its direct work. Every site is found, checked and placed by its own team after three checks: real organic traffic verified in Ahrefs, relevance to the client's niche and a clean outbound link profile. About 70% of sites fail. By its own delivery records, 94% of placements are still live after 12 months, with zero Google manual actions or client disavowals across all partners, and any link that comes down is replaced.
Its published agency proof is Digital Junkies, a digital marketing agency that resells SEO Engico's link building under its own brand and has sustained 16 to 20 links placed a month.
What stands out
- Published wholesale tiers: $145 a link, $120 from 20 a month, $105 from 40 a month
- No monthly commitment, so you can order around client demand
- Live URL report with the anchor and date for every link, ready to forward
- White-label SEO, web builds and technical fixes from the same team
Worth knowing
- There is a ten link minimum, which makes it a poor fit for a one-off single link.
- It is not built for agencies whose clients want the cheapest links or hundreds a month.

2. Outreach Monks
- Best for
- Agencies running many clients through one bulk order sheet
- Based in
- India, with an office in Jersey City, US
- Founded
- 2017
Outreach Monks has run white label link building for agencies since 2017 and says more than 500 agencies use it. The practical draw is volume handling: you can submit one sheet covering as many as 50 client domains with mixed services and DR tiers, and it tracks unique referring domains per client so placements do not overlap. Every service it sells, from guest posts and link insertions to restricted niches such as cannabis and iGaming, is available under white label.
Deliverables carry no Outreach Monks branding anywhere. Reports live in an unbranded Google Sheet you can share read-only with clients, the dashboard sits under your agency's identity, and a mutual NDA is available from day one. A named account manager owns each account, volume discounts start at 10+ links a month, and every placement has a six-month replacement guarantee.
What stands out
- Multi-client bulk orders with per-client domain tracking
- Mutual NDA and fully unbranded deliverables
- Volume discounts from 10+ links a month
Worth knowing
- Replacement cover is six months, shorter than some providers here.

No. 3
3. Vazoola
- Best for
- Agencies on tight budgets that want low per-link rates and a simple order sheet
- Based in
- New Haven, Connecticut, US
Vazoola is a link building agency in New Haven, Connecticut, and its service page is written squarely for marketing agencies. Each month you fill in an order sheet with basic details for each client, a dedicated account manager makes sure the order is filled, and editors check the content. It says it has built links since 2010 and works with more than 750,000 blogs and publications.
Prices are low and published: $50 at DA 20+, $90 at DA 30+, $130 at DA 40+ and $215 at DA 50+, each including content, one do-follow placement and quality control for up to a year, on sites with 100+ monthly organic traffic. There are no contracts or monthly fees, and a small test order is available first. Live links can appear in your dashboard in as little as five days, though orders typically complete within 30 days.
What stands out
- Published per-link prices from $50
- Test orders before you ramp up
- White-label report with the metrics you choose
Worth knowing
- Its prices rely on its Bounty Express platform, which sends publishers time-limited offers to place content, rather than pitched editorial outreach.
- It generally works with clients spending $1,000+ a month, and uses AI for first drafts with human editing.
No. 4
4. Stellar SEO
- Best for
- Agencies with legal and finance clients who need custom outreach and no minimums
- Based in
- Nashville, Tennessee, US
Stellar SEO is a Nashville-headquartered, fully remote link building agency that describes itself as a quiet outreach division for agencies. Your team keeps the strategy and the client: you set target pages, anchor rules, quality standards and monthly volume, and it handles prospecting, outreach, vetting, negotiation and content by US-native writers. It never contacts your clients, and reports arrive unbranded and ready to pass on.
There are no contracts or minimums, and prices are tiered by DA so you can build margin into retainers: $297 a link at DA 30+, $397 at DA 40+ and $600 at DA 50+. Each link includes a 27-point quality check, 750+ words of content, Ahrefs organic traffic of 1,000+ a month and no sponsored tags. Beyond guest posts and niche edits, it runs fully custom outreach for competitive industries such as legal, finance and real estate.
What stands out
- No contracts and no minimum order
- 27-point quality check and a 1,000+ monthly traffic floor
- Custom outreach for legal, finance and other hard niches
Worth knowing
- Prices sit at the upper end of per-link menus, from $297.
- It also works directly with law firms and financial institutions, so it is not an agency-only supplier.
No. 5
5. BlueTree
- Best for
- Agencies with B2B and tech clients who need placements in business publications
- Based in
- Miami Beach, Florida, US
BlueTree sells white label link building to agencies alongside its direct B2B work, using the same publication research and quality review for both. You manage the strategy and the client, and its team handles publication research, outreach, writing, editor relationships and follow-up. It bills your agency, and you set the client price and margin. It names three ways agencies use it: resold placements, overflow capacity, or a fully outsourced link team.
Monthly plans start from $3,500 for six placements on month-to-month terms, with a published baseline of DR 60+ and at least 3,000 estimated monthly organic visitors. Content comes from an in-house team of 12 B2B writers. Agencies get fortnightly progress updates and an unbranded month-end live-link report, and onboarding settles the reporting template, approvals and communication boundaries up front.
What stands out
- Fortnightly updates plus a month-end unbranded report
- Approvals and client contact rules agreed at onboarding
- 12-month link protection under its published terms
Worth knowing
- The entry plan is $3,500 a month, so it suits higher-value B2B retainers more than small local clients.
- Its publication network leans towards business and technology titles.
No. 6
6. Reporter Outreach
- Best for
- Agencies that want to resell journalist-earned coverage under their own brand
- Based in
- San Diego, California, US
- Founded
- 2017
Reporter Outreach runs a white label programme that lets agencies resell something most link vendors cannot: coverage a journalist chose to run. Under your brand, its team answers reporter requests daily, places full-feature articles with publication editors and runs link insertions on vetted sites. It does not fulfil guest posts. Reports are fully unbranded, a live tracker updates the day each link goes live, and it never contacts your clients.
Every site or publication passes six manual checks: DR, traffic, editorial standards, relevance, indexation and freshness. Agency rates are set on a strategy call and sit below its public prices, which are digital PR plans of 7, 15 or 32 placements a month and link insertions from $300 at DR 50+ to $500 at DR 70+. PR plans carry a three-month minimum, and first placements typically go live within two to three weeks.
What stands out
- Resells earned editorial coverage rather than guest posts
- Six-point manual check on every site
- Agency rate set below its public prices
Worth knowing
- Digital PR plans need a client expert willing to be quoted.
- Link insertions are offered for SaaS and tech, ecommerce, cybersecurity, financial services and HR clients.
No. 7
7. Searcharoo
- Best for
- Smaller agencies that want packaged links and branded reports from a UK team
- Based in
- Bolton, UK
- Founded
- 2018
Searcharoo is a link building and content marketing agency run by SEOs based in the UK, and it pitches agencies directly: white-label reports carry your own branding, and a dedicated account manager guides every placement. It says buying at source saves 30% to 40% against agency markup, and that it judges sites on real traffic value rather than DA, with every link on a site showing organic traffic value above 1,000.
Its catalogue covers niche edits, guest posts, monthly link packages, digital PR, tier 2 links, local citations, link audits and EEAT audits, so an agency can cover several client needs from one supplier. Niche edit packages run from $1,070 for five links to $5,870 for 23, with pre-approval included, and placements carry a six-month replacement guarantee.
What stands out
- White-label reports with your agency's branding
- Wide catalogue, from niche edits to EEAT audits
- Dedicated account manager on every campaign
Worth knowing
- Packages are fixed bundles, so check the DR mix suits each client.
- Replacement cover is six months.
How to choose a link building service for your agency
Start with the clients you actually have. If most of them are local businesses on modest retainers, you need a per-link supplier with low published rates and a quick turnaround. If you run B2B or legal accounts with bigger budgets, a partner that plans campaigns and reaches stronger publications will protect the relationship better. Many agencies end up with two suppliers: one for everyday volume, one for the clients who notice.
Then trial before you commit a client. Order a small batch for your own site or a friendly account, open every placement and check the site's traffic, topic and outbound links yourself. Read the report as if you were the client. If it would raise questions you cannot answer, so will the real thing.
Last, get the working rules in writing: who approves sites, how fast links go live, what the replacement window is, and that the supplier will never contact your client. Those four points decide whether outsourcing makes your agency look good or leaves you explaining someone else's work.
Questions to ask before you sign
- Can I run a small test order before putting a client on it?
- What is my agency rate at the volume I expect, and is there a minimum order or term?
- Can I submit one order covering several clients, and how do you stop overlap between them?
- Who approves sites before placement: me, my client or your team?
- What does a report show for each link, and is any of it branded?
- Will your team ever contact my client, and will you sign an NDA?
Frequently asked questions
What are link building services for agencies?
They are providers that build backlinks for an agency's clients so the agency can sell link building without its own outreach team. Most work white label: the provider finds sites, handles outreach and content, and delivers unbranded reports at a trade rate, while the agency owns the client relationship and sets its own price.
How much do agencies pay for outsourced link building?
It depends on site quality and volume. Published prices here run from $50 a link at Vazoola's entry tier, through SEO Engico's wholesale $145 a link, falling to $105 at volume, and Stellar SEO's $297 at DA 30+, to monthly plans such as BlueTree's $3,500 for six placements. Harder niches and stronger publications cost more.
Should an agency build links in-house or outsource them?
Outsource if links are one line in a wider SEO retainer, because hiring, training and tooling an outreach team is expensive and slow to pay back. Build in-house if link building is the product your agency is known for and you have steady volume to keep a team busy. Plenty of agencies do both, keeping strategy inside and fulfilment outside.
How do I stop a link provider contacting my clients?
Choose a provider that commits to it in writing, and keep all client details it does not need out of the brief. Several providers on this list state plainly that they never contact your clients, and Outreach Monks offers a mutual NDA from day one. Check reports and invoices for supplier branding too.
How many links a month should an agency outsource per client?
There is no fixed number. It depends on the client's competition, the strength of its site and the budget. A small local business might need a handful of strong links a month, while a competitive national client may need far more. Base the volume on a competitor gap analysis rather than a package size.
