ThotSEO Utilize artificial intelligence to analyze the semantics of your content and compare it to Google's top results. Its NLP (natural language processing) analysis goes far beyond simple keywords: it evaluates lexical diversity, readability, grammatical structure, and the informational density of your texts.

The tool integrates Prose, a free writing quality analysis module that measures readability formulas (Flesch-Kincaid, Gunning Fog, LIX), the proportion of easy/difficult sentences, and the use of modal verbs and passive voice. These indicators, derived from natural language processing, enable the production of content that is not only semantically optimized but also better understood and valued by language models.

Its internal semantic proximity-based mesh module is a considerable asset for effectively distributing link equity among your pages, without the biases of the traditional «site:» method which always favors the same pages.

Claude Code is the AI tool we use most at Astrak for everything related to SEO automation. It's a command-line coding agent that allows complex technical tasks to be delegated directly from the terminal: creating audit scripts, designing custom SEO plugins, automating workflows, generating structured schemas, and data transformation.

The power of Claude Code lies in its ability to understand SEO context and produce functional, directly deployable code. We use it to quickly create internal tools, automate reporting, develop custom technical solutions for our clients, and even generate interactive elements (calculators, quizzes, dynamic infographics) that enrich pages and improve engagement signals.

By combining Claude Code with N8N for workflow orchestration, we've built a true SEO automation ecosystem that saves us dozens of hours per month on repetitive tasks.

Rate: API usage pricing or Anthropic subscription.

n8n is an open-source automation platform that is revolutionizing SEO workflows. It allows you to connect hundreds of services (Google Search Console, Ahrefs, Slack, Google Sheets, databases) and integrate AI models to create no-code or low-code automation pipelines.

At Astrak, we use N8N to automate position monitoring, client report generation, crawl anomaly detection, and SEO task distribution within the team. It's the glue that connects our tools and saves considerable time on repetitive operational tasks.

Native integration with language model APIs (Claude, GPT-4) allows for the creation of intelligent workflows that automatically analyze data, generate contextualized alerts, and propose corrective actions without human intervention.

Rate: free (self-hosted), cloud plans starting at €24/month.

ChatGPT It has become an indispensable tool for SEO consultants. Content brief generation, meta description writing, keyword brainstorming, FAQ schema creation, rewriting, and fact-checking: its SEO use cases are numerous and varied.

At Astrak, Léo has created custom GPTs trained on the agency's SEO expertise. The first, «Léo's SEO Advice,» provides dynamic strategies based on real-world experience. The second, «SEO Audit Guidelines,» checks content compliance with Google and E-A-T guidelines. These custom assistants are available for free and offer unconventional advice that actually works.

ChatGPT is also very useful for fact-checking content before publication, a step often overlooked but which considerably strengthens the credibility and reliability of published information, two determining factors for SEO and AI visibility.

Rate: gratuit (GPT-4o mini), Plus à 20 $/mois, Pro à 200 $/mois.

It's not a specific tool, but an approach that has been a game-changer since the advent of generative AI. The design of custom SEO plugins and tools has become accessible to everyone thanks to agents like Claude Code or ChatGPT. Where previously weeks of development and a considerable budget were required, it is now possible to create WordPress plugins, automated audit scripts, interactive calculators, or internal linking modules in a few hours.

At Astrak, we regularly design custom tools to meet each client's specific needs. For example: a repetition calculator for a fitness website that ranked in the top 1 a few days after launching, an interactive dog breed selector for an animal website, or clickable infographics that dynamically filter information. These interactive elements improve user experience and generate positive engagement signals for SEO.

The key is to provide the AI with your brand's color palette, ensure the element is responsive, and specify that you are integrating the element into your CMS builder to avoid style duplication. Once the code is generated, simply paste it onto the page in a «code» or «custom HTML» block.

Rate: Varies depending on the project's complexity (often a few hours of work with AI).
