Its page [SEO writing agency](https://astrak.agency/en/seo-content-agency/) offers two modes: co-production, where the agency delivers detailed briefs (structure, angle, keywords) that your team writes, and turnkey, where it writes the content and adds it to your CMS. The process follows six steps, from SERP analysis to measuring conversions per piece of content, and the agency publishes its writing principles: answer in the first lines, information density, active voice, precise verbs. AI is an assistant, never an author: the consultant chooses the angle and outline, AI works paragraph by paragraph and every passage is reviewed. The case studies cover content rewritten at scale: the texts of [five Shopify stores selling nets and covers](https://astrak.agency/en/ombrage-use-case/), judged too generic, were reworked one by one, and the network went from 5,714 to 34,213 organic clicks over summer 2026 (×6 in one year); [Centrale Autocar](https://astrak.agency/en/centrale-autocar-155-organic-traffic-12-months/) gained 155% organic traffic in 13 months.

Platforms such as Textbroker or Redacteur.com connect you with freelance writers: the price per word is low, but the brief, review and strategy are up to you, and they are not ranked here. Pixalione and Alioze have a writing page with no published case studies or prices. 1min30 is an editorial and inbound agency whose offer is not centered on SEO. Neocamino builds writing into a marketing tool for very small businesses. Redactly, launched in 2025, is still very young. Slashr has no dedicated writing offer. Junto and Webconversion have a real writing offer, but case figures or prices that vary from one page to another. ## What an SEO writing agency should bring in 2026 Producing text costs almost nothing since generative AI arrived. What makes the difference is everything that happens before and after the writing. Here is what to expect from an agency, beyond the words. Before ### The brief Analysis of Google results for the query, search intent, angle, outline and questions to cover. A good brief accounts for half the quality of a piece of content, whether a human writes it or it is written with AI. Substance ### Expertise Google and AI assistants favor content that shows real experience: sources, examples, an identified author. A writer who knows your industry, or your expert interviewed, is worth more than a long text. AI ### AI that is directed and reviewed Google judges the quality of content, not how it was produced. AI is an acceptable tool as long as a human chooses the angle, checks the facts and reviews every passage. After ### Updating Rewriting, merging or deleting content that has dropped often pays off more than publishing new articles. An agency should be able to offer this work, not only sell new texts. ## How to choose an SEO writing agency? **Agency or platform?** Writing platforms connect you with writers at a low price per word, but the brief, review and integration are up to you. An agency handles strategy and measurement, for a higher price. So compare what is included, not only the price per word. Ask four questions: **who writes, employees or freelancers, and do they know my industry?** **What role does AI play in production, and who reviews?** **Does the price include the brief, CMS integration, images and internal linking?** **How do you measure what each piece of content brings in?** See also our method of the [inverted pyramid](https://astrak.agency/en/inverted-pyramid-web-writing/), and for visibility in AI assistants our ranking of [GEO agencies](https://astrak.agency/en/best-geo-agencies/). ## How much does SEO writing cost? A 1,000-word article costs about thirty euros on a self-service platform, and more than €150 at an agency that provides the brief, review and integration. Onze publishes the most detailed price list: €0.12 per word with a French-speaking writer, or €156 for a 1,300-word article with two rounds of feedback and integration, and €0.08 per word for AI-assisted writing. Premiere.Page starts its content at €150 excl. VAT and its blog offer at €149 excl. VAT per month. At Astrak, writing is part of the engagement, from €900 per month. Compare what is included before comparing the price per word: keyword research, brief, number of feedback rounds, internal linking, images, CMS integration and results tracking. Transparency ## Ranking Methodology About twenty players were found in Google results for "agence rédaction SEO", "rédaction web SEO" and their variants, and in the queries AI assistants run to compare agencies. Each one's site was reviewed on 15/10/2026. Platforms that connect you with writers are not ranked. The prices and results cited are those the agencies publish themselves: when two pages from the same agency contradicted each other, we used the case study page or the price list, and flagged the gap. No agency paid to appear in this ranking. #### Production Who writes, how texts are briefed and reviewed, role of AI. #### Strategy Topic selection, search intent, internal linking, updating existing content. #### Proof Cases where content grew traffic, dated if possible. #### Transparency Price per word or per article, and what it includes. ## Our opinion #### If you want to know the price before ordering **Onze** and its price per word, or **Premiere.Page** and its entry prices. #### If you publish in volume **L'Agence WAM** and its journalists, or **Empirik** and its Thot SEO optimization tool. #### If your content also needs to convert **Astrak**, which measures each piece of content on conversions, or **Eskimoz** for large accounts. ## Frequently Asked Questions ### What is the best SEO writing agency? In our selection of 15/10/2026: Astrak, Onze, L'Agence WAM, Eskimoz, Noiise, Empirik, Premiere.Page, Keyweo, Uplix and SEO Hackers. For published prices per word, Onze. For an agency with content tools, Empirik and its Thot SEO tool. For large volumes written by journalists, L'Agence WAM. ### How much does an SEO article written by an agency cost? From a few dozen euros on a platform to several hundred at an agency. Onze charges €0.12 per word with a French-speaking writer, or €156 for a 1,300-word article, two rounds of feedback and integration included. Premiere.Page starts at €150 excl. VAT per piece of content. ### Writing agency or platform: what is the difference? A platform connects you with freelance writers: you provide the brief and review. An agency handles the strategy, briefs, review, and often integration and rank tracking. ### Do agencies use AI to write? Most do, with human review: Astrak and Onze have a human rework every passage, Noiise reviews and corrects its AI-assisted content, Eskimoz has AI agents prepare its briefs. Onze also publishes the opposite case: a site penalized after publishing dozens of AI-generated texts, then recovered after they were rewritten. ### Are the writers employees or freelancers? It depends on the agency: Noiise has an in-house writing team, WAM has journalists write, Keyweo has native speakers write and translates in-house. Ask who will write your texts. ## Your content is not bringing in enough? We look at your pages and queries in Search Console, and tell you which content to write or rewrite first. Thirty minutes, no commitment.
