ResponseSource vs Serpstat in 2026: UK journalist outreach vs API-first SEO across 230 countries
ResponseSource wins earned media through live journalist requests. Serpstat wins on affordable, API-included SEO tooling across keyword research, audits, and rank tracking. Neither tracks AI visibility.
ResponseSource
Serpstat- ResponseSource has no keyword research, rank tracking, or site audit features. Serpstat has no journalist database, enquiry service, or press release wire.
- Serpstat includes API access from its $50/month Individual plan. ResponseSource has no API on any tier.
- Neither tool tracks AI model visibility: Serpstat's own pricing table lists AI model tracking as unavailable across all four tiers, and ResponseSource has no AI tracking capability at all.
- Serpstat covers rank tracking across 230 countries. ResponseSource is limited to the UK and Ireland for its journalist and media database.
- Serpstat publishes transparent pricing starting at $50/month. ResponseSource requires a sales conversation for every tier with no public price list.
ResponseSource and Serpstat are grouped in the same SEO Suites category but built for different work. ResponseSource is a UK media relations platform centered on the Journalist Enquiry Service, where journalists post live requests for expert comment and PR professionals respond directly. Serpstat is a global SEO platform covering keyword research, competitor analysis, rank tracking, and site audits, with API access included from its $50-per-month entry tier, which is unusually accessible compared to most competitors. Neither tool tracks AI visibility across ChatGPT or Gemini: ResponseSource because it is not an SEO tool at all, and Serpstat because it has explicitly not built that capability yet. If your work is UK press coverage, Serpstat cannot help. If your work is keyword research and technical SEO on a budget, ResponseSource cannot help.
The tools at a glance
ResponseSource
UK media relations platform connecting PR professionals with journalists seeking expert comment
ResponseSource has run for over two decades as the leading UK platform for the Journalist Enquiry Service, a reverse-pitch system where journalists post live requests for expert sources and PR professionals respond directly rather than cold pitching into an inbox.
The platform also includes a UK journalist database, a press release wire, and basic coverage monitoring. None of it touches organic search, keyword data, or technical SEO, and value drops close to zero for anyone operating outside the UK and Irish markets.
All three tiers require a sales conversation, with no published pricing and no API for integrating data into other systems.

Serpstat
Comprehensive SEO platform with keyword research, site audits, and API access across 230 countries
Serpstat covers the core SEO workflows: keyword research with clustering, competitor analysis, rank tracking across Google and Yandex, and technical site audits. Coverage spans 230 countries, which makes it a practical choice for international and multilingual SEO work.
The standout feature is API access from the entry-level Individual plan at $50 per month, undercutting most competitors who reserve API access for higher tiers or charge a premium for it. White-label reporting is available from the Team plan at $100 per month for agencies delivering branded client work.
Serpstat does not track AI model visibility across ChatGPT, Gemini, or any other LLM. Its own pricing table lists "AI model tracking" as No across every tier, so teams needing that channel monitored have to run a separate tool alongside it.

Need AI visibility tracking that neither of these tools provides?
Serpstat's own pricing table lists AI model tracking as unavailable on every tier, and ResponseSource has no AI monitoring feature at all since it is built for press outreach, not search. If tracking your brand across ChatGPT, Gemini, Perplexity, and Google AI Overviews is part of the job, AI Peekaboo covers those five engines with a read and write API on every plan starting at $50 per month, plus white-label delivery and a Looker Studio connector, without requiring a separate enterprise contract.

ResponseSourceSerpstatSerpstatResponseSourceSerpstatThese tools are compared here mostly because of shared category tagging rather than genuine overlap. ResponseSource has no SEO functionality whatsoever and Serpstat has no PR functionality whatsoever. The one thing they do share is a gap: neither tracks AI model visibility, which matters if brand presence in ChatGPT or Gemini answers is part of your reporting requirements.
Bottom line
Pick ResponseSource if UK earned media through journalist relationships is the job. Pick Serpstat if the job is keyword research, technical audits, and rank tracking on a budget that still includes API access from day one. Neither tool tracks AI visibility, so if that is part of your remit, plan to add a dedicated AI visibility tool regardless of which of these two you choose.
Frequently asked questions
Do ResponseSource and Serpstat actually compete for the same use case?
Not really. ResponseSource is a UK media relations platform for earning press coverage through journalist enquiries, while Serpstat is a global SEO platform for keyword research, rank tracking, and site audits. They are grouped in the same category on review sites, but a team choosing between them is usually confusing PR tooling with search tooling.
Does either tool track AI visibility in ChatGPT or Gemini?
No. Serpstat's pricing table explicitly lists AI model tracking as unavailable across all four of its plans. ResponseSource has no AI tracking capability of any kind since it is built for journalist outreach, not search monitoring. Both would need to be paired with a dedicated AI visibility tool for that channel.
Is Serpstat's API access really available on the cheapest plan?
Yes. Serpstat includes API access on the $50/month Individual plan, which is unusual since most competitors reserve API access for higher tiers or a separate add-on fee. ResponseSource has no API on any tier, published or otherwise.
Which tool is cheaper to get started with?
Serpstat has transparent pricing starting at $50 per month for the Individual plan. ResponseSource does not publish pricing for any of its three tiers; you need to contact sales for a quote regardless of which level of service you want.
Can Serpstat help with UK press coverage the way ResponseSource does?
No. Serpstat has no journalist database, enquiry service, or press release distribution feature. It is purely an SEO data platform. Teams that need earned media coverage in the UK press still need ResponseSource or a comparable PR tool.
