--- title: "Best SaaS SEO agency: our top 10 agencies for B2B software companies in France in 2026 - Astrak" url: "https://astrak.agency/en/best-saas-seo-agency/" lang: "en-US" --- Updated on **15/10/2026** · Agency sites reviewed on 15/10/2026 **What is the best SEO agency for a B2B SaaS company? On 15 October 2026, we reviewed the sites of about thirty agencies that position themselves on SaaS, and selected nine, ranked alongside Astrak.** A SaaS is not looking for traffic but for demos, trials and recurring revenue: we checked whether each agency publishes a method suited to it (comparisons, alternatives, integrations), named software company case studies, measurement through to the CRM and a price. Astrak is the author of this ranking and places itself first: the criteria are detailed below so you can judge for yourself.

Its pages [SEO SaaS Agency](https://astrak.agency/en/seo-saas-agency-2/) and [B2B SEO Agency](https://astrak.agency/en/seo-saas-agency/) start from the constraints of the model: long buying cycles, multiple decision-makers, rising paid acquisition costs. They detail the five page types that generate trials and demos ("vs" comparisons, alternatives, integrations, pages by role or industry, articles on business problems), technical SEO for SaaS sites and link building. The agency also works on AI visibility, now decisive in B2B where buyers ask ChatGPT for a shortlist. Its case study [Slidor](https://astrak.agency/en/use-case-slidor/) shows this in the US market: in three months, the share of AI answers citing Slidor on its purchase queries went from 5.4% to 21%. Clients shown include Findymail and Kowee. Engagements start at €900 per month. #### Strengths - SEO and GEO in the same engagement, measured in the same reporting. - Bilingual team, used to English-speaking markets. - SaaS pages designed for conversion: comparisons, alternatives, integrations. - Public minimum price, no commitment. #### Points to watch - Few pure-SEO SaaS case studies with figures published to date. - Engagements from €900 per month, a step above a one-off audit.

[See the Edusign case study](https://www.seo-monkey.fr/etude-de-cas/edusign/) ## Agencies we reviewed but left out About thirty agencies were reviewed. Several show an "agence SEO SaaS" page with no SaaS-specific method and no identifiable software client: we did not include them. Other well-known agencies (Growth Room, Smartkeyword) have no published SaaS page or case study. Gtec knows software companies very well and Bulldozer Collective knows scale-ups, but neither publishes SEO results with figures. Primelis shows logos of large software companies, with no readable case study. Overall finding: no agency yet publishes a complete SaaS case study, with a named client, a sales result (demos, pipeline) and a dated period. That is the first question to ask. ## What makes B2B SaaS SEO different A software company does not want traffic, it wants sign-ups, trials and demos. Search volumes are low, buying cycles are long and several people make the decision. A SaaS SEO agency must take this into account at every step. Bottom of funnel ### The pages that convert "Your software vs competitor" comparisons, "alternative to" pages, integration pages and pages by job role: low volume, but strong purchase intent. Top of funnel ### Business problems Articles that answer the questions your prospects ask before looking for a tool, and that lead them to your product. Technical ### The product site JavaScript sites, help and documentation subdomains, pages by language: crawling and indexing often need more care than on a brochure site. AI ### The assistants' shortlist B2B buyers now ask ChatGPT or Perplexity to suggest tools. Being cited in these answers is becoming a channel in its own right, and it is worked on together with SEO. ## How do you choose an SEO agency for a SaaS? Be wary of reporting that only talks about traffic and rankings. An agency suited to SaaS talks about sign-ups, demos and pipeline, and knows how to connect a page to a sales result, at least as an assisted conversion. Four questions to ask: **which SaaS companies have you worked with, and with what dated results?** **How do you prioritize between product pages, comparisons and blog content?** **Do you work in English, and in which markets?** **What do you do to get my software cited by AI?** For visibility in assistants, see also our rankings of [GEO agencies](https://astrak.agency/en/best-geo-agencies/) and [GEO consultants](https://astrak.agency/en/geo-consultant/), and for advertising our ranking of [LinkedIn Ads agencies](https://astrak.agency/en/best-linkedin-ads-agency/). ## How much does a SaaS SEO agency cost? €900 to €5,600per month, for ongoing support €1,500 to €8,000for an audit Among the selected agencies that show their prices, monthly support starts at €900 at Astrak, €975 at Onze and €1,000 at Webconversion, and goes up to €5,600 per month at Leveredge for the most intensive plan. Eskimoz states €1,500 to €5,000 per month for an SME. The audit costs €1,500 to €4,000 at Webconversion, and €2,100 to over €8,000 at Leveredge. SEO Monkey charges €500 per day. For a software company, the right benchmark is not the monthly price but the cost per demo or per sign-up, to compare with that of advertising. Transparency ## Ranking Methodology About thirty agencies were identified in Google results for "agence SEO SaaS", "agence SEO B2B" and their variants, and in AI assistant answers. Each agency's website was reviewed on 15/10/2026; all cited pages were live on that date. The results cited are those the agencies report themselves. No agency paid to appear in this ranking. #### SaaS method Comparisons, alternatives, integrations, bottom-of-funnel content: a strategy designed for software. #### Software company cases Named SaaS clients, with sales results (demos, conversions), dated if possible. #### Measurement Tracking that goes beyond traffic: demos, trials, pipeline, CRM attribution. #### Transparency Prices shown, team identified, markets covered. ## Our opinion #### If you want SaaS case studies with figures **Onze** publishes the most software company case studies; **Eskimoz** (Combo) and **AWi** (Aircall) each have a solid one. #### If you want a method designed for SaaS **Leveredge** for attribution all the way to the CRM, **Webconversion** for measurement in demos. #### If AI visibility is a priority **Astrak** (Slidor, ×3.9 citations in the United States) and **Vydera** (Beedeez) measure their results in assistants. ## Frequently Asked Questions ### What is the best SEO agency for a SaaS? In our selection of 15/10/2026: Astrak, Onze, Leveredge, Webconversion, Eskimoz, AWi, Junto, Vydera, Uplix and SEO Monkey. Onze publishes the most SaaS case studies with figures, Leveredge has the most specific method, Astrak connects SEO and AI visibility. ### How much does a SaaS SEO agency cost? From €900 to €5,600 per month at agencies that show their prices, and from €1,500 to more than €8,000 for an audit. ### Which pages should you create for SaaS SEO? First, the pages that convert: "your software vs competitor" comparisons, "alternative to" pages, integration pages and pages by job role. Blog articles come next, to reach prospects earlier. ### Is SEO profitable for a B2B SaaS? Often more than advertising over time: a well-ranked page generates demos for years with no cost per click, and the value of a SaaS customer over several years easily covers the acquisition cost. ### How do you get recommended by ChatGPT as a SaaS company? By being present in the comparisons and media that AI tools consult, by publishing clear pages on what the software does and who it is for, and by regularly measuring assistant answers on your purchase queries. ## Your SaaS deserves more demos from Google and AI We look at your Search Console and your purchase queries together, and we tell you which pages to create first. Thirty minutes, no commitment.
