Help:Redirects

When you move a page you create a redirect. So far so good. It redirects automatically.

If someone then moves the resulting page, that creates a double redirect, and the first one stops working. Anyone who reaches it has to click to go on and find the ultimate target page.

Double redirects are listed at Special:DoubleRedirects. Each entry has three page title links joined like this:

John Langan (1831-?) (Edit) →‎ John Langan (1824-?) →‎ John Langan I (1832-?)

There may be more than one such group each covering part of a set of three or more pages that all have one ultimate target. The above example was one of a set of five lines involving six pages that "redirected", but only one (the "1824" one above) redirected automatically; the other five all had to be edited so that they pointed to the ultimate target.

When you have either: then: If you found a set, paste the same target link into the others in the set by successively clicking the "edit" in each line as in step 2 above.
 * checked that there is only one line involved, or
 * found the ultimate target of a set
 * 1) highlight and copy the ultimate target (the "1832" page in the above example) then
 * 2) click the "edit" link near the start of the line and paste the target name into the brackets on the page you reach, in substitution for the link that's there
