v0.5.1: Six New H1 Heading SEO Checks
6 new H1-related SEO checks bring the total to 22 automated checks across CLI and desktop.
What’s New in v0.5.1
6 New H1 Checks (16 → 22 Total)
The SEO analysis engine now includes 6 new checks focused on the <h1> tag - the primary heading that defines each page’s main topic. The total number of automated checks goes from 16 to 22.
New checks:
- Missing H1 - Pages with no H1 tag
- Multiple H1 Tags - Pages with more than one H1, which dilutes heading hierarchy
- Empty H1 - Pages with an H1 tag that contains no text
- Long H1 - H1 tags over 70 characters that lose focus and impact
- Short H1 - H1 tags under 10 characters that are too generic to be useful
- Duplicate H1 - Multiple pages sharing the same H1 text
All 6 checks work across the CLI (crawler seo), desktop app (SEO Issues card), and CSV/TXT exports.
H1 Data in Crawl Results
The crawler now extracts H1 tags from every page during the crawl. The H1 text and count are stored in your .crawl files and JSON exports, making them available for custom analysis and reporting.
Who Benefits
- SEO professionals get deeper heading analysis without switching to a separate tool
- Content teams can catch heading structure issues across entire sites in one pass
- Developers building on crawl data get H1 metadata for every page automatically
