Protocol-relative links
WarningLow priority
Pages of this site that write addresses as //host/path, borrowing the page's own scheme.
Why it matters
Loaded over http, such a page loads its resources over http too, and some tools and crawlers read the addresses wrongly.
How to fix it
Write each address in full, with https:.
Skitter runs this check on every crawl, and lists each page it finds with the evidence: the header, the tag or the link that gave it away.
