Template-wide SEO errors: why 1 fix resolves 200 pages

2026-02-15
One of the most powerful insights from an SEO audit is discovering template-wide errors. These are issues embedded in your theme template that appear on hundreds of pages simultaneously.
Examples of template errors
- Missing H1 tags on all product pages
- Duplicate canonical tags due to a conflict between theme and app
- Images without alt text in the product template
- Schema markup with missing fields
Why this is good news
If you find an error in your template, you only need to edit one file to fix the issue across all those pages. A single change can make the difference for hundreds of pages.
How ScanLytics detects this
