VigIA - AI Visibility, Analytics & Control

The AI Visibility Score is a 100-point rating system that measures how well your site is prepared for AI crawlers and AI-powered search. It checks 20 signals across 5 categories: access and discovery, structured data, content structure, AI interaction, and performance. You get a letter grade (A+ to F) and specific recommendations to improve.

No. VigIA adds minimal overhead by checking the User-Agent string on each request. The check is very fast and only writes to the database when an AI crawler is detected.

Robots.txt is advisory - crawlers should respect it but may choose to ignore it. PHP blocking returns a 403 Forbidden response, effectively preventing access regardless of whether the crawler respects robots.txt.

Blocking AI training crawlers (like GPTBot or ClaudeBot) will not affect traditional search engine rankings. However, blocking AI search crawlers might affect how your content appears in AI-powered search results.

Markdown for Agents is a standard for serving web content as clean markdown to AI agents. Instead of processing full HTML, agents receive lightweight markdown with structured metadata. VigIA supports both dedicated .md URLs and Accept: text/markdown content negotiation. Enable it in VigIA > Extras > Markdown for Agents. Since VigIA 2.0.0 the feature also covers taxonomy archives (categories, tags, WooCommerce product categories, custom taxonomies) and WooCommerce products. Term archives include the term description, the list of child terms in hierarchical taxonomies and an excerpt of the latest entries; product .md endpoints embed schema-like data (price, sale price, SKU, stock status, rating) directly in the YAML frontmatter.

VigIA 2.0.0 classifies each crawler hit into one of these buckets, indexed in the database so filters and CSV exports are instant: Home (the / path), Post, Page, Product, any other public custom post type, Category archive, Tag archive, Date/Author archive, Feed, Sitemap, REST API, File (PDFs, images, downloads), Admin/login attempt (/wp-admin, wp-login.php — useful to spot bots probing the admin), WordPress system (admin-ajax, xmlrpc, wp-cron, wp-comments-post), 404 Not found, and Other.

Yes! In the main analytics page, scroll down to "Custom crawlers" and add your own User-Agent patterns to track.

All data is stored in your WordPress database in a custom table (wp_vigia_visits). No data leaves your server.

The llms.txt file is a standard for helping AI systems understand your website's content and structure. It provides a machine-readable overview of your site that AI can use to better represent your content. Learn more at llmstxt.org.

VigIA supports automatic noindex detection from: Yoast SEO, Rank Math, All in One SEO, SEOPress, The SEO Framework, and Native SEO NoIndexer.

The Abilities API is a new feature in WordPress 6.9 that allows plugins to expose their functionality in a standardized way. This enables AI agents, automation tools, and external systems to discover and use plugin features programmatically. VigIA implements 9 abilities for analytics, blocking, and robots.txt management.

JSON-LD (JavaScript Object Notation for Linked Data) is structured data that helps search engines and AI systems understand your site identity and content. VigIA generates two types of JSON-LD: Site Identity (WebSite + Organization/Person schema with social profiles) and AI Discovery (ReadAction pointers to your llms.txt and Markdown for Agents endpoints). This makes your AI-ready content discoverable through structured signals. Enable it in VigIA > Extras > JSON-LD.
