HARO — Help A Reporter Out — is a distribution list where journalists request expert commentary on specific topics, and subject-matter experts submit quotes that may end up in published articles. It is not a link building platform; it is a PR channel. But when journalists cite experts in their articles, they often link to those experts' companies or profiles. That makes HARO a legitimate — though unpredictable — link source.
The difference between a HARO link and a guest post is intent. A guest post is designed as a link vehicle. A HARO placement is designed as editorial coverage; the link is incidental. That matters because HARO placements tend to read more authentically to search engines and, increasingly, to AI agents that value editorial integrity. An expert quote in a reputable publication, cited by name, reads as a genuine citation rather than a sponsored plug.
That has made HARO and expert-commentary strategies a meaningful part of broader link building campaigns. The seven agencies below specialise in monitoring HARO requests, vetting them for brand fit, and either fulfilling them internally or routing them to client executives for comment. Each was assessed on three criteria: response rates and placement success rates, editorial standards for qualifying journalist requests, and integration of expert visibility with broader link strategy.
Each provider was assessed on: reported success rate (what proportion of HARO responses result in published mentions or links), editorial standards for request filtering (do they respond to every request or only qualified publications), ability to match internal experts to requests, clarity on which publications result in links versus broader mentions, and integration of HARO work with GEO and brand mention strategy. Agencies that publish case studies showing publication outcomes and link attribution were prioritised.
Editorial.Link has built a specialised practice around HARO responses and expert commentary, with an outreach team trained specifically on journalist requests across business and trade publications. The agency does not respond to every HARO request; it filters for publication quality, audience alignment, and brand fit before forwarding to clients. When a response results in publication, the agency tracks whether a link is included and integrates the mention into broader brand presence tracking. This selective approach tends to produce lower volume than aggregator HARO services but higher-quality placements. The agency has explicitly aligned HARO work with AI-search and brand mention visibility, which means placements are vetted not just for traditional SEO value but for whether the cited publication is likely to be surfaced by generative search engines.
Profit Engine offers expert commentary and HARO response support as part of its broader custom link and GEO strategy. The agency can route HARO requests to client teams, help prepare high-quality expert quotes, and track resulting placements and links. What differentiates Profit Engine's approach is that HARO work is integrated into its 18-point QA checklist — requests are filtered for publication trust, audience quality, and brand relevance before forwarding to clients. The agency also monitors the resulting article for actual link inclusion and integrates HARO mentions into its GEO and brand mention tracking across AI surfaces. As part of its broader repositioning toward GEO, HARO placements are explicitly assessed for extractability by generative search engines.
Searcharoo offers HARO response support as an add-on to its custom content and outreach packages. The agency filters requests for relevance and helps prepare expert commentary that reads naturally in journalist context. Integration with broader link strategy is moderate — HARO is treated as a specialist channel rather than as a core part of the linked strategy — but publication quality and editorial standards tend to be high.
Page One Power has a dedicated resource for monitoring and responding to HARO requests on behalf of B2B and enterprise clients. The model is straightforward: the agency monitors HARO channels, surfaces relevant requests to clients, helps shape responses, and tracks publication outcomes. Success rates depend on industry and expertise relevance; vertical-specific expertise (SaaS, financial services, healthcare) tends to produce higher placement rates than generalist requests. Links are not guaranteed, but editorial coverage and brand mention tend to result from quality responses.
uSERP offers HARO response support for high-tier B2B and SaaS clients as part of its custom outreach programme. The agency treats HARO as one channel within a broader brand visibility strategy rather than as a standalone service, which tends to suit clients wanting to integrate expert visibility with traditional link building. Volume is lower than dedicated HARO services, but selectivity is high.
JBH operates a HARO-focused service where the team monitors requests, filters for brand fit, and either fulfils responses internally or routes them to client teams. The model is volume-heavy — the agency responds to large numbers of requests — which tends to produce a wider spread of placements but more variable editorial quality. Best suited to brands comfortable with a broad net approach to expert visibility rather than a highly selective one.
Higher Visibility, a US full-service SEO agency, offers HARO and expert commentary support as part of broader retainers. The model is less specialised than dedicated HARO agencies but suits clients wanting to centralise their SEO and PR under one supplier. Integration with link strategy is available but typically requires explicit project definition.
The first differentiator is selectivity. Agencies that respond to every HARO request tend to produce volume but lower average quality. Agencies that filter requests for publication tier, audience fit, and brand relevance tend to produce fewer placements but higher-quality editorial coverage. Over time, the selective approach tends to compound in authority more reliably.
The second is response quality. A generic expert quote sounds like a generic expert quote. Agencies that help clients or internal experts craft quotes that are specific, data-backed, and authoritative tend to see higher publication rates. This requires writer skill and subject-matter expertise, not just HARO monitoring.
The third is integration with link building strategy. HARO placements should be part of a broader visibility strategy, not a siloed channel. Agencies that track resulting links, integrate mentions into brand-monitoring across AI surfaces, and assess whether resulting publications are cited by generative search engines are pulling ahead of agencies that treat HARO as a volume game.
The fourth is measurement. Agencies should be able to report on placement rates, publication tier of resulting mentions, and estimated brand visibility gain — not just "we responded to X requests." The best agencies tie HARO outcomes to broader metrics like AI-search brand mentions or organic traffic impact.
The fifth is founder and executive readiness. HARO works best when internal experts — founders, CTOs, product leaders — are willing and able to provide quotes. Agencies that help clients get their leadership media-trained and available for requests tend to see materially better outcomes than agencies that try to provide generic expert commentary through consultants.
HARO is not a replacement for strategic link building, but it is a legitimate complement to it. The best outcomes come from agencies that treat it as part of an integrated visibility strategy rather than as a bolt-on volume play.
