Altheo analyses the technical foundation of your website — crawlability, indexation, page structure, internal links, performance and LLM accessibility — identifies what is limiting your visibility, ranks the fixes and helps you implement them.
The difference from a traditional audit tool is what happens after the findings. Most tools hand you a long list of warnings you still have to interpret, prioritise and assign. Altheo turns each finding into a clear action and guides you through doing it.
Better crawlability and indexation, so your most important pages are easier for Google, Bing and DuckDuckGo to find, understand and rank — and so the issues holding them back stop doing so.
A faster, smoother site for every visitor. Speed, stability and usability problems create friction that pushes people away before they see your offer; fixing them lowers bounce rates and lets more visitors convert.
A technical GEO foundation that lets LLMs access, interpret and surface your content, so ChatGPT, Claude and Grok can cite your site as a source and are more likely to recommend your business in relevant answers.
Crawlability: robots.txt, meta robots and crawl budget, so search engines reach the pages that matter. Indexation: pages that are blocked, noindexed or missing from search entirely. Sitemap validation against your actual site.
Site speed and Core Web Vitals — LCP, CLS and INP — to catch what is slowing pages down. Broken links and redirect chains that waste crawl budget. Duplicate content and canonical issues where pages compete against each other. SSL configuration and mixed content.
AI crawler access: whether GPTBot, ClaudeBot and others can actually reach your pages. Structured data and semantic HTML, so pages are easier to parse. Plus an llms.txt generator, and image and SVG compression that runs entirely inside your browser.
Altheo crawls your pages, sitemap and technical structure to understand how your site is built, then analyses crawlability, indexation, performance, HTML structure and LLM accessibility.
Every issue is ranked by urgency, likely impact and implementation effort, separating critical problems from quick wins so you always know what comes first.
Each recommendation becomes a practical action with step-by-step guidance and suggested changes, rather than another overwhelming technical report. Once fixes are live, the foundation starts working harder across search, site performance and AI visibility.
Altheo analyzes the technical foundation of your website, including crawlability, indexation, page structure, internal links, website performance and LLM accessibility. It identifies the issues limiting your visibility or website experience, prioritizes the most important fixes and helps you implement them correctly.
Traditional tools often give you a long list of technical warnings that still need to be interpreted, prioritized and assigned. Altheo combines built-in technical tools with your company context, turning every finding into a clear action and guiding you through the implementation process.
Altheo does more than run an audit. It explains why each issue matters, shows what needs to change and provides practical guidance to help you implement the fix. Once an action is completed, you can track your progress and continue improving the technical health of your website.
A slow or difficult-to-use website can push visitors away before they explore your offer. Improving speed, stability and usability creates a better experience, reduces bounce rates and gives more visitors the opportunity to become leads or customers. Strong website performance can also support better visibility across search engines.
Altheo helps search engines and LLMs access, crawl and understand your most important pages. This includes improving technical SEO, page structure, internal linking and AI accessibility. These improvements can strengthen your visibility across Google and Bing while increasing the chances of your content being surfaced or cited by platforms such as ChatGPT and Claude.
An llms.txt file provides LLMs with a structured overview of the pages and content you consider most important. It can make your website easier for AI systems to navigate and understand, although it does not guarantee citations or recommendations. Because the standard is still developing, it should complement strong content and technical SEO rather than replace them.
The llms.txt generator is free for anyone, with no account and no email required — enter a URL and copy or download the file. Inside Altheo, the Free plan adds a sitemap analyzer and daily credits to chat with Altheo about your website. More advanced analysis, recommendations and ongoing workflows are available through the paid subscription.
