Tool details and privacy
Paste a list of addresses. Each one gets a badge with what splits one page into several addresses: repeats, capitals, http and https, www, an ending slash, extra parameters, tracking tags, and #.
The same page under several addresses splits its links and rankings. Spotting the variants is the first step to fixing them.
