A link building service is an agency or productised vendor that obtains hyperlinks from other websites to a client's pages, usually to raise the client's visibility in search engines. Providers range from strategy-led agencies that create research, data stories and resources that publishers cite, to per-link vendors that sell placements on vetted blogs at fixed prices by Domain Rating (DR) tier, and self-service marketplaces where advertisers buy articles directly from site owners.
The category sits inside search engine optimisation and overlaps with digital PR. It is shaped by Google's spam policies, which define link spam as "creating links to or from a site primarily for the purpose of manipulating search rankings" and list buying or selling ranking-passing links, excessive link exchanges, automated link creation and guest posts with keyword-rich anchors as examples. Google states that paid links are not a violation when they carry a rel="sponsored" or rel="nofollow" attribute.
This list covers 13 live providers in four service models, with published prices, guarantees, ownership and documented limitations taken from each vendor's own pages as reviewed in November 2026.

What is a link building service
A link building service is an outsourced provider whose deliverable is a set of backlinks: links on third-party websites that point to the client's domain. The deliverable distinguishes it from broader SEO agencies, which sell audits, technical fixes and content, and from SEO software and backlink checker tools, which measure links but do not acquire them. Many providers in this list also sell content writing, local SEO citations or technical SEO, but link acquisition is their core product.
Four models are common. Strategy-led agencies such as Page One Power and Siege Media build campaigns around linkable assets and outreach and quote a custom monthly fee. Retainer link builders such as Editorial.Link, BlueTree and LinkBuilder.io sell a fixed number of links per month on placements with a stated DR floor. Per-link vendors such as The HOTH, fatjoe, Loganix, Authority Builders, Rhino Rank and Outreach Monks publish a price per placement by tier. Marketplaces such as Collaborator list publisher sites and let buyers order placements themselves.
Link building also differs from public relations agencies: digital PR aims at news coverage and treats links as one outcome, while link builders treat the link as the unit of delivery. The boundary is blurred, since several vendors here now sell digital PR and press-release distribution alongside placements.
History and market
Paid and outreach-based link acquisition grew with Google's use of links as a ranking signal, and the industry has repeatedly reorganised around Google's enforcement. The HOTH, founded in 2010, says its founders ran a Chicago SEO agency that was "repeatedly set back" by the Panda and Penguin updates before it launched as a white-label SEO service; it added guest posts and press releases in 2015. Page One Power was founded in Boise, Idaho, in 2010 by Jon and Zach Ball and adopted its current name in 2012. fatjoe dates from 2012, Authority Builders from 2016, LinkBuilder.io from 2016, and Rhino Rank and Outreach Monks from 2017. Editorial.Link launched around 2020 as an offshoot of Admix Global, a publishing company started in 2016.
Google publishes the dates of its ranking updates on the Search Status Dashboard. In the period covered by this list it ran spam updates starting 26 August 2025, 24 March 2026, 24 June 2026, 18 August 2026 and 24 September 2026, and core updates in March, June and December 2025 and March, May and November 2026. Each spam update is a reminder that the guarantees vendors give (permanence, DR, traffic) do not extend to how Google treats the links.
Since 2025 most providers have repositioned toward visibility in AI search assistants. uSERP lists "GEO/AEO/AI search" as a service, Editorial.Link sells "listicles for LLM boost", BlueTree sells a GEO / AI Visibility Audit, Outreach Monks sells "AI brand mentions", and Siege Media's founder has written a book titled Generative Engine Optimization. No vendor reviewed for this list publishes audited figures for the size of the link building market, and none is quoted here.
Key features to compare
Acquisition method
Providers differ in whether they earn links through outreach and content that publishers choose to cite, or buy placements from site owners. Siege Media states that it "will never buy links or mentions" and Page One Power describes "manual outreach with no paid placements", while per-link vendors price placements directly. The method determines exposure under Google's link spam policy.
Site quality floors
Most vendors state minimum metrics. BlueTree guarantees DR 60+ sites with at least 3,000 organic visits; Outreach Monks vets for DR40, 500+ monthly visits, a spam score under 5% and ad density under 30%; Loganix's entry tier accepts DR/DA 30+ sites with 100–500+ monthly visits. Third-party metrics such as DR are vendor-calculated scores, not Google signals.
Pre-approval and transparency
Some vendors let buyers approve sites before outreach (Editorial.Link lists pre-approval on every plan; Loganix counts turnaround from the date the buyer approves site selections), and Page One Power reports each placed link with its DR, traffic, anchor and URL.
Replacement and refund guarantees
Replacement windows vary: six months at Outreach Monks, twelve months at Rhino Rank, BlueTree and Authority Builders, and a "lifetime link guarantee" at fatjoe. Collaborator offers a free three-month guarantee against deletion and non-indexing.
Turnaround
Published delivery times range from 7–10 days for most Authority Builders guest posts and "from 14 days" at fatjoe to about three weeks at Loganix and 20–35 days for full Outreach Monks orders.
Contract terms
Retainers range from month-to-month (BlueTree) to six-month terms with 60-day (uSERP) or 90-day (LinkBuilder.io) opt-outs.
White-label and agency options
fatjoe reports more than 40,000 agency accounts, and Editorial.Link, BlueTree and Outreach Monks all advertise white-label or agency pricing.
Pricing models
Vendors charge in three ways. Per placement: fatjoe's blogger outreach runs from US$72 for a DR10+ placement to US$456 for DR60+; The HOTH charges US$175 per Link Outreach link at DR 20+, US$200 per link insertion and US$405 per DR 50+ Platinum Link; Loganix starts at US$200 and US$400 per guest post; Authority Builders starts at US$160; Rhino Rank starts at US$60 per curated link and US$75 per guest post; Outreach Monks starts at US$99 per DR20 placement.
Monthly retainers with a link quota: Editorial.Link sells five links for US$1,750 and twenty for US$6,000; BlueTree charges US$3,500 a month for six links up to US$7,500 for 15+; LinkBuilder.io runs from US$2,999 a month for eight links to US$19,999 for 53+.
Custom retainers: Page One Power quotes after a discovery call and says it is "not the cheapest option"; Siege Media says digital PR engagements start around US$12,000–15,000 a month when content and promotion are combined; uSERP's FAQ says comparable services "all start at around $10,000 per month". Marketplace prices are set by individual publishers; sample Collaborator listings showed base prices of US$40–91.
How to choose
By budget. Buyers spending under US$1,000 a month are limited to per-link vendors and marketplaces (Rhino Rank, Outreach Monks, fatjoe, Authority Builders, Collaborator). Between roughly US$2,000 and US$10,000, fixed-quota retainers (Editorial.Link, BlueTree, LinkBuilder.io) apply. Above US$10,000, strategy-led agencies (Siege Media, uSERP, Page One Power) become an option.
By risk tolerance. Buyers who want to stay clearly within Google's link spam policy can favour providers that state they do not pay for placements (Siege Media, Page One Power), or ensure purchased placements carry rel="sponsored".
By company type. SaaS and B2B companies are the stated focus of BlueTree, which names Freshbooks and Mailbird, and of uSERP, which names monday.com and CrowdStrike. Agencies reselling links are the main customer base of fatjoe and Outreach Monks.
By region. UK-based buyers may prefer fatjoe or Rhino Rank, both headquartered in England; US-based buyers have Page One Power (Idaho), uSERP (Colorado) and several Florida-based vendors. Collaborator lists sites in 157 countries and 52 languages for non-English campaigns.
Methodology
Entries were selected from providers whose core product is backlink acquisition, that operate a live website under the listed name, and that publish enough information (pricing, guarantees, process or company history) to be described from primary sources. Every price, date, address and client name comes from the vendor's own pages or from Google, accessed in November 2026.
Entries are grouped by service model in descending order of engagement depth: strategy-led agencies (ranks 1–3), retainer link builders with published plans (4–6), per-link vendors (7–12) and a self-service marketplace (13). Within each group, providers are ordered by years in operation as stated on their own sites, with publication of prices as a tie-breaker. No user reviews, star ratings or test orders were used, and no provider paid for inclusion. Vendor-reported results (traffic growth, links built, client counts) are reported as company claims.
The list
1
Boise-based link building and SEO agency operating since 2010
Best for: Mid-size and enterprise brands wanting earned links with no paid placements
Page One Power is a US link building agency founded in 2010 in Boise, Idaho, by brothers Jon and Zach Ball; it adopted the Page One Power name in 2012 and is still based in Boise. Its services include link building and digital PR, on-page and technical SEO, AI search optimisation, internal linking and schema markup.
The company sells custom campaigns only: its service page states "No packages. No tiers." A strategist prepares a proposal after a 15-minute discovery call and a backlink gap audit against competitors, followed by linkable-asset creation, manual outreach to vetted publishers, monthly reporting and quarterly reviews. Page One Power says it uses "manual outreach with no paid placements" and assigns a US-based project manager to each client. It reports having secured "hundreds of thousands" of backlinks and developed more than 6,100 on-site assets for clients; these are company claims.
The model suits companies wanting a long-running, low-risk programme with full visibility into each link, since every placement is reported with publisher DR, organic traffic, anchor text and URL. Its main limitations are the absence of published prices or minimums and the company's own statement that it is "not the cheapest option".

Logos shown on the site include Zillow, Airbnb, HubSpot, Zapier and PayPal, and case studies feature Purple, Hippo and Mentimeter.

It cites a network of more than 7,500 media relationships and case results including 733 links for Bluevine and a 2,300% increase in links to the Vena Solutions blog; these are company figures. Siege states that it does not guarantee a specific number of mentions and "will never buy links or mentions".
Engagements are expensive relative to placement vendors: the company says services that combine content creation and promotion start around US$12,000–15,000 a month, with smaller retainers possible only when the client produces content in-house.

It does not publish an owner, headquarters or founding entity on the pages reviewed. Sites are vetted against more than 40 criteria, and the company says it adds hundreds of new sites weekly, places links in articles (usually on inner pages) and does not sell private blog network or homepage links.
Guest posts start at US$160 per link, with prices varying by domain authority, organic traffic and niche; bulk and agency discounts are negotiated case by case. Most orders are completed within 7–10 days of payment, while A-List Premium Editorial Links take four to six weeks. A product called ABC Plus adds competitor link analysis, an anchor text roadmap and month-to-month reporting.
Authority Builders offers two specific guarantees: linking domains must deliver 1,000+ monthly visits or the buyer is refunded and keeps the post, and links removed within a year that cannot be restored are replaced or refunded. The company states its links are "do-follow, not sponsored", which places them in the category Google's spam policy describes as paid links that should be qualified with rel="sponsored" or rel="nofollow".

UK curated-link and guest-post vendor with low entry prices
Best for: Agencies and small teams testing a placement vendor at low cost
Rhino Rank is a UK link building company founded in 2017 and based in Shrewsbury, England, with more than 40 UK employees and fulfilment handled in-house. It lists both UK and US telephone numbers and sells to agencies and in-house teams.
Its products are curated links (link insertions into existing articles) from US$60 per link, guest posts from US$75, visual links from US$60, listicle placements from US$135 and press releases from US$99. Prices rise with the metrics of the target site, but the pricing page does not break them down by DR tier.
Rhino Rank offers a no-questions-asked refund on a customer's first order, up to US$550, and 12-month replacement cover on every delivered link. Those terms make it one of the lower-risk ways to trial a placement vendor financially, although the policy risk of paid ranking-passing links described in Google's spam policies applies equally to curated links and guest posts. Buyers who need strategy, competitor analysis or reporting beyond delivery will find the product narrower than retainer services.

- Guest posts from US$75
- Listicle placements
- Press release distribution
- First-order refund up to US$550
- 12-month replacement cover

White-label guest post and niche edit provider for SEO agencies
Best for: SEO agencies needing white-label guest posts at volume
Outreach Monks is a link building provider founded in 2017 by co-founders Sahil Ahuja (CEO) and Shireen Walia (COO). It reports more than 70 in-house staff across outreach, content, quality assurance and strategy and output of more than 4,000 links a month. The site says it is trusted by "500+ agencies and SEO professionals across 40+ countries" in one place and cites 700+ clients in another, so the client count is inconsistent.
Its services are guest posts, white-label link building, managed link building, niche edits, SaaS backlinks, white-label SEO and "AI brand mentions". Prices start at US$99 per link for DR20 placements and rise with DR, niche difficulty and traffic, with bulk discounts for agencies and no retainer or lock-in. The company's stated vetting standard for sites is a minimum DR40, 500+ monthly organic visits, a spam score under 5% and ad density under 30%.
First links go live within seven days and a full order takes 20–35 days. Placements removed within six months are replaced free, a shorter window than the 12-month or lifetime guarantees offered by several competitors. Its niche edits and guest posts are paid placements under Google's link spam policy.

- White-label reporting for agencies

Self-service marketplace for buying guest posts from 40,000+ sites
Best for: Experienced in-house SEOs buying non-English placements directly
Collaborator (collaborator.pro) is a self-service marketplace where advertisers buy guest posts and press-release placements directly from site owners, and publishers list their sites and earn from accepted orders. At the time of review its catalogue showed 45,702 websites and more than 3,000 Telegram channels, and it claimed placements in 157 countries and 52 languages. The pages reviewed do not state the operating company, founding year or headquarters.
Prices are set by each publisher; sample listings showed base prices between US$40 and US$91 plus an additional amount of US$10–25, and some publishers offer discounts for fast placement. The marketplace charges a one-time commission whose rate is not published on the home page. Buyers receive a free three-month guarantee against deletion and non-indexing, with a paid one-year guarantee available.
Unlike the managed services above, the buyer selects sites, writes or orders content and checks quality, so results depend on the buyer's own vetting. The breadth of non-English sites is its main distinction. Placements bought through a marketplace are paid links in the sense of Google's spam policy unless qualified with rel="sponsored" or rel="nofollow".

Frequently asked questions
Is buying backlinks against Google's guidelines?
Google's spam policies list buying or selling links that pass ranking credit as link spam, including exchanges of money, goods or services for links. Paid links for advertising are allowed when they carry rel="sponsored" or rel="nofollow". Most per-link vendors sell do-follow placements, so the policy risk sits with the buyer.
How much do link building services cost?
Published prices in this list range from US$60 per curated link at Rhino Rank and US$72 per DR10+ placement at fatjoe to retainers of US$2,999–19,999 a month at LinkBuilder.io. Strategy-led agencies such as Siege Media and uSERP say their engagements start around US$10,000–15,000 a month.
What is the difference between a guest post and a niche edit?
A guest post is a new article written for a third-party site that contains a link to the client. A niche edit, also called a link insertion or curated link, adds the client's link to an article already published and indexed. The HOTH charges US$200 per insertion and Rhino Rank from US$60 per curated link.
How long does link building take to show results?
Vendors give similar estimates. The HOTH says most clients see ranking movement within about 90 days and significant results in six to twelve months, and LinkBuilder.io says significant results take at least six months. Delivery of the links themselves ranges from about a week to a month depending on the vendor.
What is Domain Rating (DR) and does Google use it?
Domain Rating is a third-party score of a site's backlink profile calculated by the SEO tool Ahrefs. Vendors use DR tiers to price placements, but it is not a Google ranking factor. Several vendors therefore add organic traffic floors, for example BlueTree's minimum of 3,000 monthly visits per site.
What guarantees do link building services offer?
Guarantees usually cover link permanence, not rankings. fatjoe offers lifetime replacement, Rhino Rank, BlueTree and Authority Builders twelve months, Outreach Monks six months and Collaborator three months free. BlueTree states explicitly that no package guarantees rankings, and Siege Media does not guarantee a number of links.
Is digital PR the same as link building?
Digital PR earns links and mentions through news coverage of research, data or expert commentary, while link building services usually deliver a set number of placements. Siege Media and Page One Power work mainly through earned coverage and outreach; per-link vendors sell placements. Many vendors now offer both.
