Nevertheless, the world of redirects is a murky one, as several types of redirects exist for various situations. So it’s essential to know the variations between them.
On this information, you’ll study:
Redirects are a strategy to ahead customers (and bots) to a URL aside from the one they requested.
There are two the reason why you must use redirects when transferring content material:
- Higher consumer expertise for guests – You don’t need guests to get hit with a “web page not discovered” warning once they’re attempting to entry a web page that’s moved. Redirects clear up this drawback by seamlessly sending guests to the content material’s new location.

Redirects are cut up into two teams: server-side redirects and client-side redirects. Every group incorporates a variety of redirects that search engines like google view as both short-term or everlasting. So that you’ll want to make use of the precise redirect for the duty at hand to keep away from potential search engine marketing points.
Server-side redirects
A server-side redirect is one the place the server decides the place to redirect the consumer or search engine when a web page is requested. It does this by returning a 3XX HTTP standing code.
In case you’re doing search engine marketing, you’ll be utilizing server-side redirects more often than not, as client-side redirects (we’ll focus on these shortly) have a number of drawbacks and are usually extra appropriate for fairly particular and uncommon use instances.
Listed here are the 3XX redirects each search engine marketing ought to know:
301 redirect
A 301 redirect forwards customers to the brand new URL and tells search engines like google that the useful resource has completely moved. When confronted with a 301 redirect, search engines like google sometimes drop the previous redirected URL from their index in favor of the brand new URL. In addition they switch PageRank (authority) to the brand new URL.
302 redirect
A 302 redirect forwards customers to the brand new URL and tells search engines like google that the useful resource has quickly moved. When confronted with a 302 redirect, search engines like google hold the previous URL listed regardless that it’s redirected. Nevertheless, when you depart the 302 redirect in place for a very long time, search engines like google will doubtless begin treating it like a 301 redirect and index the brand new URL as an alternative.
Like 301s, 302s switch PageRank. The distinction is the switch occurs “backward.” In different phrases, the “new” URL’s PageRank transfers backward to the previous URL (except search engines like google are treating it like a 301).
303 redirect
A 303 redirect forwards the consumer to a useful resource just like the one requested and is a short-term type of redirect. It’s sometimes used for issues like stopping kind resubmissions when a consumer hits the “again” button of their browser. You gained’t sometimes use 303 redirects for search engine marketing functions. In case you do, search engines like google could deal with them as both a 301 or 302.
307 redirect
A 307 redirect is identical as a 302 redirect, besides it retains the HTTP technique (POST, GET) of the unique request when performing the redirect.
308 redirect
A 308 redirect is identical as a 301 redirect, besides it retains the HTTP technique of the unique request when performing the redirect. Google says it treats 308 redirects the identical as 301 redirects, however most SEOs nonetheless use 301 redirects.
In case you use it like a 301 we’ll deal with it as such.

Consumer-side redirects
A client-side redirect is one the place the browser decides the place to redirect the consumer. You usually shouldn’t use it except you don’t have an alternative choice.
307 redirect

It is because HSTS tells the consumer’s browser that the server solely accepts safe (HTTPS) connections and to carry out an inside 307 redirect if requested to request unsecure (HTTP) assets from the positioning sooner or later.
Meta refresh redirect
A meta refresh redirect tells the browser to redirect the consumer after a set variety of seconds. Google understands it and can sometimes deal with it the identical as a 301 redirect. Nevertheless, when requested about meta redirects with delays on Twitter, Google’s John Mueller mentioned, “If you need it handled like a redirect, it is smart to have it act like a redirect.”
Both approach, Google doesn’t suggest utilizing them, as they are often complicated for the consumer and aren’t supported by all browsers. Google recommends utilizing a server-side 301 redirect as an alternative.
JavaScript redirect
A JavaScript redirect, as you most likely guessed, makes use of JavaScript to instruct the browser to redirect the consumer to a special URL. Some individuals consider a JS redirect causes points for search engines like google as a result of they need to render the web page to see the redirect. Though that is true, it’s not often a problem for Google as a result of it renders pages so quick as of late. (Although, there might nonetheless be points with different search engines like google.) All in all, it’s nonetheless higher to make use of a 3XX redirect the place potential, however a JS redirect is usually high quality if that’s your solely choice.
Redirects can get difficult. That will help you alongside, listed here are a number of finest practices to bear in mind when you’re concerned in search engine marketing.
