Best Off-Page SEO Agencies in APAC: Five to Compare
A few SEO agencies CMOs in APAC should know, with real publisher ties, multilingual reach, and proven traffic lifts.
Choosing the right off-page SEO partner in Asia-Pacific can make or break your organic growth strategy. For general managers and CMOs navigating Southeast Asian market entry or scaling across the region, the challenge isn't just finding an agency that builds backlinks. It's finding one that understands multilingual outreach, maintains real publisher relationships, and delivers measurable traffic lifts without exposing your brand to toxic link penalties.
The APAC off-page SEO landscape concentrates expertise in Singapore and Hong Kong, where agencies have spent years cultivating relationships with regional publishers, academic institutions, and industry platforms. Unlike Western markets, where link-building often relies on automated outreach, top Asian specialists combine manual editorial control with deep local knowledge. They know which .edu domains carry weight in Jakarta, which Thai lifestyle blogs drive referral traffic, and how to navigate Baidu's unique authority signals for cross-border campaigns.
This shortlist gives you five agencies with verifiable track records, using objective signals like SEO industry awards, client retention rates, documented traffic growth, and multilingual capabilities. Each profile includes specific outcomes, risk management approaches, and what makes them suited to different enterprise needs across Southeast Asia, Greater China, and Oceania markets.
What Separates Effective Off-Page Partners?
Before diving into individual agencies, understand the criteria that matter for APAC off-page work. Client retention rates above 75% signal consistent delivery. Awards from APAC Search Awards or Clutch's verified reviews provide third-party validation. Documented case studies with specific percentage lifts in organic traffic or domain authority prove operational capability.
Multilingual depth determines whether an agency can execute in Thai, Vietnamese, Bahasa Indonesia, or Mandarin, not just translate English content. Regional publisher access, measured by existing media partnerships or editorial placements in outlets like Straits Times or Vulcan Post, directly impacts link quality.
Transparent ROI tracking through dashboards that tie backlink acquisition to revenue or lead generation separates strategic partners from tactical vendors.
White-hat methodology has become non-negotiable post-2024 Google updates. Agencies that require full editorial control, manually vet every outreach target, and maintain toxic link auditing processes protect your domain authority while building it. The five agencies below are in no particular order and meet these thresholds with different strengths suited to various market priorities.

First Page Digital
Enterprise-Grade ROI Tracking Across Singapore and Hong Kong
First Page Digital leads APAC's enterprise off-page market with 63% year-over-year growth in 2024, the highest expansion rate among regional SEO specialists. Their Singapore and Hong Kong operations focus on localized backlink profiling that aligns with how search engines weight authority differently across Asian markets.
Key Details:
- Headquarters: Singapore, with key offices in Hong Kong and Australia
- Specialization: Full-funnel SEO with dedicated off-page programs combining link earning and digital PR
- Notable Work: Scaled a Malaysian fintech's backlink profile by 410% in six months using localized digital PR outreach; ranked among Singapore's Top Link Building Companies by Clutch in November 2025
- Industry Recognition: Extensive verified client reviews on Clutch; recognized for multilingual execution across APAC markets
What sets First Page apart for general managers is their ROI-tracking dashboards built specifically for enterprise backlink campaigns. These systems connect individual link placements to downstream metrics like assisted conversions, organic revenue attribution, and cost-per-acquisition changes. For CFOs demanding proof that off-page budgets drive business outcomes, this transparency aligns SEO investment with board-level growth targets.
Their localized approach matters in markets where domain authority signals vary. A .edu backlink from a Singaporean university carries a different weight than one from Thailand, and First Page's regional teams understand these nuances. They've built publisher relationships across nine Asian markets, enabling editorial placements that search engines recognize as genuine authority signals rather than paid links.
For enterprises entering Southeast Asian markets or scaling across Singapore, Hong Kong, and Australia simultaneously, First Page's regional footprint and proven scalability make them a natural fit. Their pay-on-performance options also reduce risk for brands testing APAC expansion.
StudioHawk
Award-Winning Digital PR for Editorial Link Earning
Australia-based StudioHawk brings an SEO-only focus unusual in full-service agency markets. Their Digital PR practice specializes in earning high-authority editorial links through newsworthy campaigns rather than transactional outreach, a distinction that matters for long-term domain health.
Key Details:
- Headquarters: Australia, serving APAC and global markets
- Specialization: Digital PR-led link earning with focus on high-DR editorial placements
- Notable Work: Multiple enterprise and e-commerce brands; documented success in competitive verticals
- Industry Recognition: Winner of Global Search Awards 2025 "Best Large Agency"; multiple APAC Search Awards wins from 2022 to 2024
StudioHawk's approach centers on creating content that journalists actually want to cover. Instead of asking publishers to link to product pages, they develop data studies, industry surveys, or visual assets that earn organic editorial mentions. This method produces links that carry more authority because they're embedded in genuine news stories or analysis pieces.
For brands in finance, healthcare, or regulated industries where link quality matters more than quantity, StudioHawk's editorial focus reduces compliance risk. Their campaigns generate placements in tier-one publications where readers, not just search bots, see your brand. This dual benefit of SEO authority and brand visibility justifies higher per-link costs for enterprises prioritizing reputation alongside rankings.
Their track record across APAC, validated by three consecutive years of regional awards, demonstrates consistent execution. General managers planning thought leadership campaigns or market education initiatives can take advantage of StudioHawk's PR capabilities to build authority while earning backlinks as a secondary benefit.

Prosperity Media
Scale-Focused Link Acquisition with In-House Teams
Prosperity Media operates at the intersection of volume and quality, maintaining in-house outreach and content teams that enable large-scale link acquisition without sacrificing editorial standards. Their Digital PR agency practice earned recognition at the 2025 APAC Search Awards for "Best Use of PR in a Search Campaign."
Key Details:
- Headquarters: Australia, with regional clients including Singapore
- Specialization: Link acquisition and Digital PR at scale; fully in-house operations
- Notable Work: Over 1,000 links earned on top-tier news sites; documented campaigns across e-commerce, finance, and B2B sectors
- Industry Recognition: Best Large SEO Agency and Best Use of PR in a Search Campaign at 2025 APAC Search Awards
Prosperity's in-house model matters for enterprises needing rapid scaling. External freelance networks introduce quality control risks and communication delays. By keeping outreach, content creation, and relationship management internal, Prosperity maintains consistency across hundreds of monthly placements while adapting quickly to campaign feedback or market shifts.
Their documented success earning over 1,000 links on high-authority news sites demonstrates both publisher access and operational capacity. For brands launching across multiple APAC markets simultaneously or running aggressive growth campaigns, Prosperity's infrastructure supports volume without the toxic link risks that plague cheaper offshore alternatives.
The agency's focus on measurable outcomes, combined with its award recognition for integrating PR strategy with search goals, appeals to CMOs who need off-page work to support broader brand initiatives. Links earned through newsworthy campaigns deliver referral traffic and brand mentions alongside SEO benefits, maximizing marketing budget efficiency.
DEJAN Marketing
Research-Driven Link Strategy with Proprietary Tools
DEJAN Marketing brings a technical, research-oriented approach to off-page SEO that appeals to analytically minded executives. Operating since 2002, they've built proprietary tools like Fresh Link Finder to support advanced link acquisition and auditing.
Key Details:
- Headquarters: Australia, serving APAC and global markets
- Specialization: Advanced link acquisition, link audits, and R&D-driven SEO methodology
- Notable Work: Documented experiments and case studies published openly; long-standing link-building practice with transparent processes
- Industry Recognition: Veteran operator with research pedigree; publicly documented link-building methodologies
What distinguishes DEJAN is its willingness to publish detailed process documentation and experimental results. While competitors guard methodologies as trade secrets, DEJAN's transparency helps clients understand exactly what they're paying for. Their link-building processes, outlined publicly, show the manual vetting, outreach personalization, and quality thresholds applied to every campaign.
For enterprises burned by previous agencies using questionable tactics, DEJAN's open-book approach rebuilds trust. Their proprietary monitoring tools provide ongoing visibility into backlink health, alerting teams to toxic links or competitive threats before they impact rankings. This proactive risk management matters for brands in competitive verticals where negative SEO attacks occur.
DEJAN's research focus also means they stay ahead of algorithm changes. Their documented experiments with link velocity, anchor text distribution, and authority flow help clients understand not just what works now, but why, and how strategies might need to adapt as search engines evolve.

Infidigit
Enterprise Link Building with Vertical Specialization
India-based Infidigit has built deep experience in enterprise categories like financial services, retail marketplaces, and insurance, where regulatory constraints and competitive intensity demand specialized off-page approaches. Their documented case studies show measurable ranking and visibility lifts in 2025.
Key Details:
- Headquarters: India, serving APAC and global markets
- Specialization: Link building and Digital PR for enterprise verticals with strong analytics and reporting
- Notable Work: Insurance brand case study showing ranking and visibility improvements through strategic link acquisition; programs across BFSI, retail, and marketplace sectors
- Industry Recognition: Over 60 awards across search programs; verified case study library
Infidigit's vertical specialization matters because link strategies for financial services differ fundamentally from e-commerce or B2B software. Compliance requirements limit outreach tactics, publisher relationships need vetting for brand safety, and anchor text must avoid regulatory triggers. Infidigit's experience navigating these constraints in hyper-competitive categories like insurance and banking reduces execution risk.
Their case study library provides transparency rare in the industry. Instead of vague claims about "increased traffic," Infidigit publishes specific percentage lifts, timeframes, and methodology details. For procurement teams evaluating multiple vendors, this documentation enables apples-to-apples comparison of expected outcomes.
The agency's robust reporting infrastructure, built for enterprise clients demanding granular visibility, tracks link acquisition velocity, referring domain quality scores, and correlation with organic performance metrics. For general managers overseeing large SEO budgets across multiple markets, Infidigit's analytics make it easier to justify continued investment or reallocate resources based on performance data.
Risk Management: Protecting Domain Authority While Building Links
Every agency on this list emphasizes white-hat methodology, but understanding specific risk controls helps you evaluate proposals. Manual outreach processes, where humans personally vet every target site and customize every pitch, prevent the spam footprints that trigger penalties. Toxic link auditing, conducted quarterly at a minimum, identifies and disavows harmful backlinks before they impact rankings.
Editorial control requirements, where your agency must approve content placement and anchor text, ensure links appear in genuinely relevant contexts. Avoid agencies promising "guaranteed" link quantities without quality thresholds. The best partners set targets based on your domain's current authority and competitive landscape, then adjust tactics based on what earns placements versus what gets ignored.
Transparency in reporting separates strategic partners from vendors. Dashboards should show not just links acquired, but referring domain authority, traffic sent, and correlation with ranking improvements for target keywords. Monthly reviews should include competitive backlink analysis, showing how your profile compares to rivals and where gaps exist.

Localization Depth: Why Regional Publisher Access Matters
Generic international link-building fails in APAC because search engines weigh local signals heavily. A backlink from a Vietnamese lifestyle blog carries more authority for Vietnam rankings than one from a US tech site, even if the latter has a higher global domain rating. Top agencies maintain relationships with regional publishers, understand local content preferences, and employ native speakers who can pitch stories that resonate culturally.
Multilingual capabilities go beyond translation. Effective outreach in Thai requires understanding formal versus informal language registers, cultural taboos, and which topics interest specific publisher audiences. Agencies with in-market teams in Bangkok, Jakarta, or Manila execute more effectively than those managing Asia from Sydney or Singapore alone.
For brands entering new APAC markets, partner agencies should demonstrate existing publisher relationships in your target countries. Ask for examples of placements they've secured in local-language sites, not just English-language regional publications. The quality of their media database directly impacts your campaign velocity and link relevance.
ROI Attribution: Connecting Off-Page Investment to Business Outcomes
CFOs rightly question off-page SEO budgets because links don't directly generate revenue. The agencies above address this through attribution modeling that connects backlink acquisition to downstream business metrics. Advanced tracking shows which referring domains send traffic that converts, enabling you to prioritize similar placements.
Assisted conversion reporting reveals how organic visitors influenced by off-page authority contribute to sales cycles. A prospect might first discover your brand through a backlinked article, return via paid search, and convert after an email nurture sequence. Proper attribution credits the initial off-page touchpoint appropriately.
Revenue-per-link analysis, calculated by dividing organic revenue growth by links acquired in the same period, provides a rough cost-benefit metric. While imperfect due to lag time and multiple variables, it gives finance teams a framework for evaluating off-page ROI similar to other marketing channels.
Partnership Decision Criteria
Start by clarifying your primary objective. Brands prioritizing rapid market entry need agencies with existing regional publisher networks and multilingual teams. Those focused on enterprise credibility should emphasize editorial quality over volume. Companies in regulated industries require vertical experience and compliance-aware outreach.
Evaluate case studies for relevance to your situation. An agency's success with e-commerce brands may not translate to B2B software or financial services. Look for examples in similar verticals, target markets, and competitive intensity levels. Request references from clients in comparable situations.
Assess cultural and operational fit through discovery calls. Agencies should ask detailed questions about your business model, competitive landscape, and internal approval processes before proposing tactics. Cookie-cutter proposals signal they'll apply generic playbooks rather than customized strategies.
Budget alignment matters less than cost structure transparency. Understand whether you're paying per link, per campaign, or on retainer, and what quality thresholds govern delivery. Performance-based models reduce risk but may limit agency motivation to exceed minimum targets. Retainers with clear KPIs often produce better long-term results.
Off-Page SEO in 2025 and Beyond
Search engines continue tightening quality signals, making white-hat methodology and editorial link earning increasingly important. Agencies that rely on PBNs, link exchanges, or low-quality directories face declining effectiveness and rising penalty risk. The partners listed here have adapted by emphasizing genuine publisher relationships and newsworthy content.
AI-generated content creates new challenges as search engines work to identify and devalue synthetic backlinks. Agencies with human-led outreach and editorial oversight will maintain effectiveness while competitors using automated tools see diminishing returns. Ask potential partners how they're adapting to AI detection and what safeguards prevent synthetic content from entering their link-building workflows.
Regional specialization will become more valuable as search engines refine local authority signals. Generic APAC strategies give way to market-specific approaches that understand Singapore's unique digital ecosystem differs fundamentally from Thailand's or Indonesia's. Agencies with true in-market presence and native teams will outperform those managing Asia remotely.
The five agencies profiled here represent different approaches to off-page SEO excellence in APAC. First Page Digital offers enterprise scale with ROI transparency. StudioHawk brings award-winning Digital PR for editorial authority. Prosperity Media delivers volume through in-house infrastructure. DEJAN provides research-driven methodology with proprietary tools. Infidigit specializes in enterprise verticals with proven case studies. Your optimal choice depends on market priorities, budget parameters, and strategic objectives for 2025 growth across Southeast Asia and beyond.
