301 Redirect Chains, Intro to an Advanced SEO Topic
By Mike Krass
This is a little bit of a teaser post, but we wanted to go over the concept of what a 301 redirect chain is.
- What it is
- Impact on your website
- Impact on page authority
- Whenever you're doing any type of site migration or if you're changing URLs a lot, how it's critical to look into this element and make sure none of the 301 redirects you have in place are chaining.
So 301 redirect chains:
I’m going to give you a little bit of a tease here.
Essentially, you can think of a 301 redirect like this:
You go to from an old URL to a new URL. From a user standpoint, it’s hardly noticeable. For a search engine one, it’s definitely noticeable. A 301 redirect is like giving the post office a change of address card to search engines.
In this scenario you will retain anywhere from ninety-five to ninety-nine percent of any and all link authority and the page authority of that old URL.
With a redirect chain, you amplify the loss by two, three, four, five, six times.
Essentially you have knowingly (or unknowingly) set up a 301 redirect to a URL with another 301 redirect. This is a 2 chain redirect.
Now for a worst-case scenario: If you have a chain of five, you’re only retaining sixty to seventy-five-ish percent of that page authority! If you’re talking about a whole bunch of URLs that could have a significant impact on your website.
That’s a little bit of a teaser of what we’re going to be talking about in a future post. The next post will go deeper on the definition of a redirect chain, how to run a couple of reports using some free tools you may or may not have access to to find those 301 redirect chains, and how to fix them.
