Eliminating pages from your website, changing your page URLs or domain name requires a lot of redirecting. If you don’t set redirects up, links to your site become a dead end – you lose valuable inbound links. In essence, you’re setting up detour signs – “This thing is no longer here. Go over here.” And to make sure your website isn’t an internet version of Dublin where everything is under construction all the time and you suddenly run into roadblocks for no particular reason, you’ll need to implement the right type of redirects on your website. But first, some education. Let’s talk about what a redirect is and what it actually does. When you type www.pointblank.ie into your browser, the browser sends a request to our server. The server then sends your browser back the page that was requested. A redirect places instructions on the server to provide something different than the original request. When the browser asks for Red, the server has instructions saying “Red isn’t here anymore, give them Pink instead.” And then Pink is delivered to the user.
301 redirects are by far the most common type of redirect. They are server-side. Typing a URL into your browser or clicking on a link sends a request for the page to the server of the website. A 301 redirect is a set of instructions which are executed when the request hits the server, automatically re-routing to a different page. They’re the focus of most SEO efforts during a site migration.
302 redirects are not as common as 301 redirects and are considered a “temporary relocation.” These are used in site maintenance, but since most sites have a maintenance mode where developers and admins can test changes before they go live, this type of redirect is rarely used today.
“Multiple choice” redirects brings up multiple options for the same resource. It’s rarely used, but it does have some important applications – multilingual sites and different file extensions being two good examples.
“Protocol change” used to be more common for things like HTTP to HTTPS, but now that’s handled by a “RewriteEngine” that uses 301s
Redirects are by far the most common method of redirection where the redirect request is handled at the server level. The original request does not load, and the server reads the instructions and delivers a different page rather than loading the first request.
Redirects occur when the redirect is encoded into a page rather than set on a server level. The request for the site is sent, the resource begins to load, and then there are directions during loading that reroute them.
Allow for redirecting of multiple pages to one resource. For example, if you have com/category/* and your platform supports wildcarding, then all subpages of “/category/” will redirect to a specified resource.
When a URL does not exist and the server has no instructions on where to route the user request, a 404 error message is delivered. It’s highly recommended you set up a 404 page for your users which allows them to search for their selected resource rather than simply bouncing off the website.
Canonical tags don’t return a status code number; instead, they specify to a search engine that two pages contain very similar content. Specifying a canonical allows search engines to understand that two pages aren’t duplicates of one another; they simply have the same information. A common use of canonical is in the world of e-commerce where two category pages will often contain the same products.
The web is built by people who are addicted to caffeine, so it makes sense there’s a whole set of protocols and statuses built for it.
Most likely as you move things around your site and remove old pages, you’ll be using the 301 redirect protocol to make sure everything’s in line. Here’s what you need to know.
(it’s really just a line or two of code) so they will not have a significant impact on site speed.
but one URL can’t be redirected to several URLs.
Or to a page which 301 redirects to itself. This creates an infinite loop and nothing will ever load- it’s basically webpage ping-pong.
This is the big one
According to Moz, anywhere from 90-99% of the link value passes from the original page to the redirected page. There are some pitfalls to this, however:
So if you redirect a page that was about flowers to one about balloons, the relevance of those links decreases. Even redirecting link value from a page about roses to a page about flowers – it’s still not exactly the same, and a lot of those links might have anchor text containing “roses” and the flowers page only mentions roses once. It’s a bit of a disconnect that could affect the effectiveness of your links.
There is no conclusive information on how much link value is passed when multiple pages are redirected to one. You’re getting the benefits of several pages worth of link equity….but are there diminishing returns on that link equity? It’s impossible to tell for sure, but early data suggests each redirect has less value than the first, and after 5 no value is passed between pages at all.
Bing and Yahoo! handle things a bit differently. Back in 2010, Bing didn’t pass equity at all, but it appears they updated that policy. Most of the time, Google is the engine bringing home your bacon, but if you have lots of volume from Yahoo or Bing, you might want to take extra precautions.
It’s best to keep URLs intact as you migrate to avoid any loss of link equity and to keep things as clean as possible, but it’s pretty likely that you will have to make at least a few redirects. The best practices for this include:
