How to set up URL standardization for SEO optimization

If you run a blog or site, you will be putting a lot of effort into SEO optimizing.

I didn’t pay much attention to this part because WordPress is SEO-optimized, but recently there was a problem with the site and I discovered that URL and IP are not standardized in the process of fixing it.

When it comes to standardization (normalization), I can say what it means, but if it’s easy to understand, when you write a post, a URL is created and Google indexes the post. Can be recognized.


For example, if you do not standardize URLs, both URLs with and without www will be created as pages, and if you do not standardize on IP, pages may be created for both site URLs and IP URLs.

1. Reasons for standardizing SEO optimization

If you list the important parts of the Google Help Center

  • You can specify which URLs will be displayed to people in search results.
  • Link signals related to similar or duplicated pages can be incorporated.
  • Simplify tracking of metrics related to a single product/subject.
  • You can avoid wasting time crawling on duplicate pages.

If I list articles on overseas sites about standardization work,

  • If your search crawl has to go through too much duplicate content, some content may be missing.
  • Large-scale replication can degrade the ranking.
  • Even if the content is ranked, search engines may choose the wrong URL as the source.

From the above, you can conclude that it is better to standardize in order to SEO optimization.

2. IP standardization

The reason I learned about IP standardization is that I confirmed that a page containing an IP address was created in the Google Search Console. So, in order to fix this part, I searched overseas sites and found a way, but just add the rule to the htaccess file.

How to edit htaccess file, if you are using Yoast SEO, go to Tools tool and you can see File Editor, where you can edit. If you don’t use Yoast SEO, there are plugins that can help you edit, so you can install it and modify it.

※ When modifying files, it is recommended to make a backup before working. There was a situation where I couldn’t access the site while I was working on it.


Here, you can replace XXX.XXX.XXX.XXX with your own dedicated IP address and enter the site address as your own.

This is a 301 redirect rule that redirects anything coming from a dedicated IP address to a site address.

3. URL standardization

URL standardization involves choosing with or without www in the site address, and specifying the post address as a canonical page. First your choice for www is to add a rule to your htaccess file.


You can add rules like IP standardization, but change example\.com to your own site address. If you want to select the one without www, you can enter the site address in reverse.

Specifying the standard page of the post can be done by directly entering the canonical tag, but it can be difficult for those who are not familiar with it, such as me. So I specified it using the Yoast SEO function.


If you use Yoast SEO Premium, you will see Advanced at the bottom. Click on this to see the Canonical URL input space and add your post’s unique address here.

I wasn’t familiar with this feature, so I entered the homepage address for each post and encountered a big frustration. I hope you don’t make a mistake like me.

I told you about SEO optimization standardization (normalization), and I made a mistake while doing this, and the site didn’t work properly. That’s why I tried to explain it in as much detail as possible, but it may be insufficient.

So, if you want to find out more and work on it, you can see a lot of data if you search for URL Canonicalization or IP Canonicalization on Google, so please look at and refer to more materials to add one of the SEO optimization factors.
