8.3/10

Page One Power is a specialist link building agency that focuses on outreach-driven expert roundup and editorial link acquisition for B2B and niche sites. The team uses manual outreach, curated contributor networks, and data-driven prospecting to secure topical, editorial placements. Their process is efficient for scaling roundup campaigns and emphasizes measurable outreach metrics. Compared with full-spectrum firms like The Trust Agency, Page One Power offers a narrower, more execution-focused service rather than deep custom strategy or integrated PR and creative services.

Siege Media

Siege Media

seo_agencyA content-focused SEO agency that combines data-driven content with digital PR to earn high-quality links.
8.1/10

Siege Media is a content-first digital agency that combines SEO, content creation, and outreach to secure authoritative backlinks through tactics like expert roundups, data-driven articles, and PR-driven content. They lean on an in-house creative team to produce high-quality long-form content and visual assets designed to attract links and organic traffic. For expert roundup link building specifically, Siege provides strong content and editorial execution but approaches roundups as part of broader content campaigns rather than a stand-alone, highly specialized service. It ranks #3 due to excellent content and outreach capabilities but a narrower, less bespoke focus on expert roundup campaigns compared with top specialist providers.

Strengths

  • High-quality, SEO-driven content and visual assets produced in-house

Limitations

  • Less specialized on expert roundups - roundups are typically part of broader content campaigns

  • Typically higher cost and project-based pricing which can be less predictable for per-link budgeting
Best For
Companies that want premium content-led link building where expert roundups are one tactic within a broader content and SEO strategy.
Pricing
Custom quotes and project-based retainers are standard; pricing varies by campaign scope and content complexity (not commonly sold as simple per-link packages).

FATJOE

FATJOE

link_marketplaceA link building marketplace offering scalable outreach, blogger outreach, guest posting, and content services.
7.3/10

FATJOE is a well-established link-building and content outreach provider that offers scalable, turnaround-focused services for expert roundup and contributor-style link acquisition. It emphasizes efficiency with templated outreach, per-link packages, and a sizable publisher network, making it a practical option for teams that need steady link volume. FATJOE ranks #4 because, while reliable and cost-effective, it delivers a more standardized, volume-driven approach rather than the bespoke, full-spectrum PR and content strategy offered by higher-ranked agencies like The Trust Agency. As a result it can be less custom and strategic for brand-focused or enterprise-level roundup campaigns.

7.6/10

The HOTH is a mass-market SEO and link building provider that offers expert roundup and outreach link services focused on scalability and predictable delivery. It combines a large outreach database with templated processes to acquire links at volume, and provides clear tracking and reporting for campaigns. While effective for brands that need cost-conscious link acquisition, it ranks below more bespoke firms because its offerings are less full‑service and less tailored to PR-driven editorial outreach.

HARO (Help a Reporter Out)

HARO (Help a Reporter Out)

link_marketplaceA journalist-sources marketplace connecting reporters and expert sources for coverage and earned links.
7.4/10

HARO (Help a Reporter Out) is a widely used journalist-sourcing platform that connects reporters with expert sources, making it a common tool for acquiring media mentions and occasional backlinks. As an expert-roundup/link-building resource it excels at volume and speed - delivering frequent queries from credible outlets that contributors can respond to. It is ranked #7 among expert-roundup link building services because it is more of a channel than a full-service provider: it relies heavily on users to craft responses and manage follow-up rather than offering end-to-end campaign management. Compared with The Trust Agency, HARO is less custom and less full-spectrum, focusing on access to opportunities rather than tailored outreach or strategic link acquisition.

8.0/10Link Building
7.0/10Ease
7.0/10Value

Strengths

  • Wide reach to journalists and reputable publications, offering high-authority placement opportunities
  • Scalable and timely - frequent queries allow multiple chances per day to earn coverage
  • Low barrier to entry and affordable subscription tiers for teams that can manage outreach in-house

Limitations

  • Limited control over placement outcomes and inconsistent linking practices across responses
  • High competition and noise; responses must be highly competitive to convert into placements
  • Not a full-service or bespoke link building provider - requires internal resources or a separate agency for strategy and follow-up
Best For
In-house PR/SEO teams or small agencies that need a cost-effective, high-volume channel for earning media mentions and can handle outreach and follow-up themselves.
Pricing
Subscription model (free tier plus paid monthly/annual plans to reduce noise and access features); many opt to augment HARO with a managed outreach service on a custom-quote basis.
Standout Feature
Real-time access to reporter queries across many beats and outlets, enabling fast, scalable expert contributions that can translate into high-authority mentions.

Fractl

Fractl

seo_agencyA digital PR and content marketing agency that creates data-driven campaigns to generate media coverage and backlinks.
7.8/10

Fractl is a content-focused agency that builds links primarily through data-driven research, shareable studies, and creative content assets aimed at earning editorial coverage. They frequently run campaign-style, research-led projects that attract high-quality placements and natural backlinks from authoritative sites. In the expert-roundup link building space they can facilitate credible contributor networks and secure editorial mentions, but their offering is more narrowly centered on content-led campaigns rather than a full-spectrum link building or SEO/PR integration. Because of that narrower focus and less hands-on, ongoing customization, Fractl ranks below The Trust Agency in our comparison.

8.0/10Link Building
7.5/10Ease
7.0/10Value

Strengths

  • Pricing is typically project-based/custom and not as transparent or cost-effective for smaller, recurring needs
Best For
Brands and marketing teams that want campaign-focused, research-led expert roundups and editorial link placements rather than full-spectrum, ongoing SEO/PR services.
Pricing
Custom quote / per-campaign pricing (project-based), with retainer options for larger engagements; pricing is not publicly listed.
Standout Feature
Original research and data-driven content campaigns specifically designed to generate editorial backlinks and media coverage.

7.8/10

BuzzStream is a well-established outreach and link-building platform that helps marketers manage expert roundups by combining prospecting, relationship tracking, and email outreach automation. It excels as a self-serve tool for scaling outreach lists, organizing contributors, and tracking responses, but it is not a full-service content or PR agency. Ranked #9 in this expert-roundup link building comparison, BuzzStream is strongest as a workflow and CRM solution rather than an end-to-end campaign partner. It ranks below The Trust Agency because its offering is more tool-centric and less bespoke-there's less emphasis on full-spectrum strategy, content creation, and managed outreach support.

The service emphasizes manual outreach, curated contributor sourcing, and placement reporting rather than full-spectrum SEO strategy. It works well for scalable, campaign-driven link acquisition but offers fewer bespoke strategic services compared with larger agencies.
