Complete How-To Guide: Running the 50-Point PDF SEO Audit

Step-by-step audit process

• Step 1: Schedule 2-3 hours for the full audit. Create a spreadsheet with all 50 points and columns for Pass/Fail, Notes, and Priority.
• Step 2: Section 1 (Inventory): Use your Wix Media Manager export and site:domain filetype:pdf search to complete the inventory check.
• Step 3: Section 2 (Metadata): Download each priority PDF and check properties. Record Title, Author, Subject, Keywords, and filename for each.
• Step 4: Section 3 (Content Structure): Open each PDF and verify text selectability, heading structure, and embedded links.
• Step 5: Section 4 (Accessibility): Run each priority PDF through the PAC accessibility checker. Record errors by category.
• Step 6: Section 5 (Performance): Check file sizes, page loading impact, and review GA4 data for PDF-related events.
• Step 7: Score each section out of 10. Calculate a total PDF SEO score out of 50.
• Step 8: Prioritise failed items: metadata and filename fixes are quick wins (Section 2). Accessibility fixes require more effort (Section 4).
• Step 9: Create an action plan with specific tasks, owners, and deadlines for each failed item.
• Step 10: Re-audit failed items in 30 days. Run the full 50-point audit quarterly.
