How this service works
The viewport meta tag of a page: whether it is present and its content (name= or property= form), plus length and a note when the value looks wrong (empty, too long, or a placeholder). One tag, one answer, for SEO and social-preview checks. $0.01 per page.
Output
Returns whether the viewport meta tag is present on the page, its raw content string, the length of that content, and a note if the value appears malformed (e.g. empty, too long, or a placeholder). Covers both name= and property= tag forms.
Example use cases
SEO audit for mobile readiness
“I'm doing an SEO audit on myshop.com — can you check if it has a viewport meta tag and whether the value looks correct, or if it's missing or broken?”
Diagnosing mobile display issues
“Our site techblog.io is rendering weirdly on mobile — can you look up its viewport meta tag and tell me what it's set to and whether the value seems valid?”
Bulk site quality check for an agency
“I need to verify that clientsite.net has a proper viewport meta tag before we launch — can you fetch it and flag if the value is empty, too long, or a placeholder?”
Technical details
Endpoint
GEThttps://site.intel.rallylive.ca/site/meta/viewport?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need a quick, focused check of just the viewport meta tag on a specific page — ideal for SEO audits, mobile-readiness checks, or site quality pipelines where you want a single-tag answer without running a full site crawl. Prefer it over general HTML scrapers when you only care about viewport presence and validity.
Side effects
- Page URL is unreachable or returns non-200 status
- Page has no HTML head section to parse
- Tag content is empty — returns presence=true but flags the note
- Value is a placeholder string — flagged in the note field
- Request times out for slow-loading pages
