Google’s John Mueller warns not to change URLs for SEO reasons. Is he right? It depends, of course. Here are some exceptions.
Personally, I change outdated, harmful or lengthy web addresses (a.k.a., URLs) when updating existing content quite often.
Why? Let me explain.
What did Google’s John Mueller say about changing URLs for SEO?
Before we dive in, let’s see what the official Google position on changing URLs for SEO seems to be. It’s quoted from a tweet by John Mueller, Search Advocate at Google, as the connection between webmasters and the search giant.
As reported by Barry Schwartz on Search Engine Roundtable, Mueller stated that the risk is much higher than the possible reward when changing URLs (for SEO reasons):
“(…) Will it help the site? Very, very rarely (if they have terrible URLs that you can’t even copy & paste, maybe). Will a change negatively affect the site for a while until it’s reprocessed? Probably. Some risk + usually no gain.”
How does a proper URL look in the first place?
Let’s start with the ideal state of your URL.
In case you are using WordPress or a similar CMS, you will most likely have a well-designed URL structure already by current standards.
The examples below are all fine:
example.com/post-title
example.com/topic/post-title
example.com/topic/sub-topic/post-title
Does your URL look anything like this? Congratulations! You most likely do not have to change anything!
It’s just like Mueller said: the risk of changing a URL would outweigh any imagined benefit.
Examples of potentially harmful URL structures
Custom websites and even content management systems of the early days often create harmful website addresses.
You may even run a legacy WordPress site that has some mistakes of the past still built in.
Does your website address look like some of the potentially harmful examples below?
All these were pretty common until a few years back, so you may still have a site with a less optimal URL structure like one of the above.
Also, with website builders and complex enterprise-level CMS software, you may have additional issues.
Sometimes, website builders like Weebly or Squarespace add gibberish to file names when dealing with special characters from foreign languages.
Numbers-only post addresses are short and sweet, but there is no reason to click them. They are bland and meaningless.
Date-based addresses make sense only for publications that truly publish time-sensitive news, like The New York Times (e.g., https://www.nytimes.com/2022/10/12/business/wall-street-mixed-quarterly-earnings.html). For everybody else, it may discourage people from clicking a link to evergreen content because they assume it’s just “yesterday’s news”.
Keyword-stuffed URLs can ostracize visitors as they are viewed as low quality and Google might also demote them in search results.
Very long, hard-to-read URLs with lots of redundant elements can simply confuse people.
URL parameters that often contain other website names or even addresses (like utm_source=Twitter.com) are utterly confusing. They can even mislead scripts on third-party sites where you share content.
When to change URLs for SEO reasons
So when can you change URLs? Ideally, never – not only for SEO reasons. It’s “never change a running system” as an old computer geek motto says.
However, we are not living in an ideal world (and I understand that Mueller’s tweet is too short to add all the exceptions). So here, we’ll go over instances when it’s OK to change URLs.
Sometimes URLs are completely bonkers as in the example offered by Patrick Cunningham on LinkedIn:
