Turn PDF Documents Into Discoverable Content
PDF SEO · AI Search Optimization · Generative Engine Optimization (GEO) · Answer Engine Optimization (AEO)
We created this free plugin to solve a problem we kept seeing in client projects: valuable PDFs buried behind raw file links, invisible to search engines and AI. Now available for WordPress, Drupal, React, and Next.js.
Why Raw PDF Links Cost You Traffic
Exposed File Paths
Links like /wp-content/uploads/report.pdf reveal server structure and look unprofessional in shared URLs.
Zero Search Visibility
Raw PDF files lack title tags, meta descriptions, and schema - search engines can't rank what they can't parse.
Blank Social Previews
Sharing a PDF link on LinkedIn or Twitter produces an empty card - no thumbnail, no excerpt, no clicks.
No Engagement Data
Without analytics, you have no idea which documents drive conversions or how far readers scroll.
Broken Brand Experience
The browser's built-in PDF viewer strips away your navigation, design, and calls-to-action.
Unreliable on Mobile
PDF rendering differs across iOS Safari, Chrome, and Samsung Internet - some users see nothing at all.
What the Plugin Does Differently
Every feature we wished existed - so we built them
Branded Document URLs
Replace /uploads/doc.pdf with clean paths like /pdf/annual-report/ that reinforce your brand identity.
Deep SEO Integration
Works with Yoast SEO and Metatag module to generate proper title tags, canonical URLs, and DigitalDocument schema automatically.
Rich Social Cards
First-page thumbnails are extracted and served as OpenGraph and Twitter Card images - every share looks professional.
Document Access Controls
Toggle print and download permissions per file. AJAX-based loading keeps direct file URLs out of page source.
Per-Document Analytics
Built-in counters track views for each document so you can measure which content resonates.
Cross-Browser PDF.js Renderer
Mozilla's PDF.js ensures pixel-perfect rendering from desktop Chrome to mobile Safari - no browser quirks.
Adaptive Appearance
Light and dark viewer themes that automatically align with your site's existing color scheme.
Flexible Embedding
Gutenberg block, Drupal field formatter, React component, or shortcode - embed PDFs wherever your stack needs them.
Document Library Page
An auto-generated archive at /pdf/ lists all published documents with CollectionPage structured data.
Ready for the AI Search Era
Search is evolving beyond traditional rankings. Our plugin ensures your documents are structured so that AI assistants like ChatGPT, Claude, and Perplexity can understand, reference, and recommend them.
Structured Semantics
Schema.org DigitalDocument vocabulary gives AI models a clear map of each document's purpose, authorship, and topic.
Machine-Readable Metadata
JSON-LD blocks expose title, author, date, and format in a standardized way that LLMs can parse without scraping.
Taxonomy Signals
Categories, tags, and descriptions act as additional ranking signals for both traditional crawlers and generative engines.
