Capital letters in the address
WarningLow priority
Addresses of this site whose path has capital letters in it.
Why it matters
Most servers treat the path as case-sensitive, so a link written in the wrong case is a 404 — or worse, a second copy of the same page.
How to fix it
Serve the page from a lowercase address and redirect the mixed-case one to it.
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.
