How this service works
Does a website use hreflang alternates? Fetches the page (homepage for a bare domain) and matches hreflang alternates's fingerprints in the HTML and response headers, returning yes/no with the evidence snippet and the category (meta). Technographics for sales, competitor research and migration planning, one technology per call. $0.01 per check.
Output
Returns a yes/no verdict on whether the site uses hreflang alternates, along with the matching evidence snippet found in the HTML or HTTP response headers and the detection category (meta). Costs $0.01 USDC per check.
Example use cases
Competitor international SEO audit
“Check if shopify.com uses hreflang alternates — I'm doing competitive research on how top ecommerce platforms handle international SEO.”
Pre-migration technographic check
“Before we migrate the site, can you verify whether acme.com currently has hreflang tags in place so we know what international SEO signals we need to preserve?”
Sales prospecting for localization tool
“I'm building a prospect list for our localization platform — can you check if stripe.com uses hreflang so I know whether they're already targeting international markets?”
Technical details
Endpoint
GEThttps://site.intel.rallylive.ca/site/uses/hreflang?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need a fast, low-cost single-domain check for hreflang implementation as part of technographic research, SEO auditing, pre-migration planning, or sales prospecting. Prefer this over manual inspection or full crawl tools when you only need a yes/no signal with evidence for one domain at a time. For bulk checks across many domains, consider the sibling bulk endpoint if available.
Side effects
- Site is unreachable or returns an error — check may return no result or an error state
- Domain redirects to a different page, causing hreflang fingerprinting on an unexpected page
- Hreflang implemented via JavaScript rendering only — static HTML fetch may miss it
- Rate limiting or bot-blocking by the target site preventing the fetch
- Bare domain resolution failure if the domain is inactive or misconfigured
