PILLAR 2, TOPICAL CONTENT · 2.1 Title & metaHighInferred
Invalid elements closing <head> early
A stray or invalid element in the head can make the browser close the head early, dropping any tags after it, title, canonical, meta, into the body where they may be ignored.
What it is
Stray tags terminate the head prematurely.
Why it matters
Directives/canonicals after the break are ignored.
How to fix it
Keep only valid head elements before content.
How to find it on your site
- View source and check that all head tags are valid head elements.
- Look for stray text, unclosed tags or body-only elements inside the head.
- Validate the HTML to catch a prematurely closed head.
- Fix the offending markup so the head stays intact.
Cross-reference to ranking and citation factors
If the head closes early, important tags after it can be ignored, which silently undermines titles, canonicals and meta. Valid head markup protects them all.
Impact
Medium-high; silent failures. Inferred.
