Say you want to change pages in your site.
No problem just change it, you say. But is that all?
- Think of all the pages linking to your current site. They all get a "404 page not found" error.
- Think of the search engines which will not produce the right results
- Think of your pagerank which will vanish instantly
The answer to all of these problems are redirects.
What are redirects?
Let's say you have this page
http://www.example.com/example, and you want to change that to
http://www.example.com/other_example. That will give you all the above problems. But what if you could say: If someone hits the first page (example) then automatically redirect to the second one (other_example). Wouldn't that be great? Well you can.
You have the site like above example. So now you rename the url fom <code>example</code> to <code>other_example</code> as demonstrated below.
Once you have done that, the old name does not exist anymore. So we are going to create a redirect. Go to
Administer -> Site building -> URL Redirects and click
Add redirect on the top of that page.
