When setting up a new website, one of the first decisions you must make is whether to use www or non-www in your domain. For example:
example.com
At first glance, the difference seems small — just three extra characters. But this decision has technical implications, SEO considerations, performance effects, and long-term scalability impacts. Many developers and business owners wonder:
Does choosing www or non-www affect SEO?
Does it change how Google indexes a site?
Is one version faster, safer, or more modern?
In this comprehensive guide, we’ll break down everything you need to know about www vs non-www, including the technical differences, advantages, drawbacks, and how to make the best choice for your website in 2025.
What Is WWW? What Is Non-WWW?
WWW (World Wide Web)
The www prefix is actually a subdomain. Technically, www.example.com is a separate hostname from example.com.
Historically, www was used to indicate that the service being served is a website — as opposed to:
mail.example.com
ftp.example.com
api.example.com
Although this distinction is less important today, www still has strong technical reasons to exist.
Non-WWW (Naked Domain / Apex Domain)
A non-www URL is simply the domain without a prefix:
example.com
This is called a naked or apex domain. It is clean, minimal, and modern-looking — which is why many startups and tech brands prefer it today.
WWW vs Non-WWW: Detailed Pros and Cons
Both options work. Google does not prefer one over the other from an SEO perspective. But the technical behavior and scalability options differ.
Let’s analyze both.
Advantages of Using WWW
1. Better DNS Flexibility and CDN Compatibility
WWW can use a CNAME record, which allows load balancing, instant DNS updates, and smoother CDN integration.
Apex domains cannot use CNAME — they must use an A or ALIAS record.
This matters for:
Cloudflare
Fastly
Amazon CloudFront
Akamai
Netlify
If you expect heavy traffic or global scale, www offers more flexibility.
2. Improved Cookie and Storage Isolation
Cookies set on www.example.com do not automatically apply to other subdomains.
This gives you better control over:
authentication
sessions
storage
security
With www, you can isolate cookies so they don't affect:
api.example.com
admin.example.com
blog.example.com
This helps performance and reduces unnecessary cookie bloat.
3. Avoiding Browser Compatibility Issues
Some older software, email clients, and corporate systems more reliably detect and linkify www.domain.com over naked domains.
While rare today, this still occurs in enterprise environments.
4. WWW Handles Traffic Spikes Better
Large sites (Amazon, Google, Facebook) use www because of its better DNS scalability and load-balancing control.
If you ever scale to millions of visitors, www is often easier to manage.
Disadvantages of WWW
1. Longer, Less Clean URL
www adds three extra characters, making the domain look old-fashioned in some industries.
example.com
vs
www.example.com
In branding-heavy industries, shorter often wins.
2. Less Popular Among Modern Startups
Brands like Stripe, Notion, Figma, GitHub, and Vercel overwhelmingly use non-www.
Modern audiences often expect simplicity.
Advantages of Using Non-WWW
1. Cleaner, Shorter, More Modern
example.com is simpler, minimalist, and easier to type.
It looks better on:
business cards
branding materials
mobile devices
UI/UX layouts
2. Trendy for Startups and Tech Companies
Many startups prefer non-www for aesthetic reasons. It signals a modern, sleek brand identity.
3. Fewer Characters = Faster Recognition
Shorter URLs are easier to:
remember
share
scan
type on mobile
Disadvantages of Non-WWW
1. Limited DNS Flexibility
Apex domains must use:
A records
ALIAS records (if supported)
ANAME records (depending on DNS provider)
They cannot use CNAME records, which limits:
dynamic load balancing
advanced CDN features
some cloud-native services
2. Cookie Leakage to Subdomains
If you set cookies on example.com, they propagate to all subdomains:
api.example.com
dashboard.example.com
blog.example.com
This can:
increase page load size
create security concerns
cause unexpected behavior
3. Some Tools Still Expect WWW
Older systems may not treat non-www URLs as clickable links.
Rare, but possible.
So Which One Is Better for SEO? WWW or Non-WWW?
Google has clearly stated:
There is no SEO advantage for www or non-www.
What matters is consistency.
SEO does not change which version you choose, but it does matter that:
Only one version is indexed
The other version has a proper 301 redirect
The preferred domain is set in Google Search Console
Your SEO strategy remains unaffected as long as you avoid duplicate content issues caused by inconsistent usage.
Choosing the Best Option: Practical Guidelines
Choose WWW if:
You expect heavy global traffic
You use multiple subdomains
You want clean cookie isolation
You want optimal CDN and DNS flexibility
You operate at enterprise or SaaS scale
Choose NON-WWW if:
You want a clean, modern, minimal brand identity
You are a startup or small business
You prefer shorter, memorable URLs
Your site is simple with few subdomains
The Most Important Rule: Be Consistent
Regardless of your choice:
Use only one version everywhere
Redirect the other version using a 301 permanent redirect
Update internal links
Configure canonical tags
Set the preferred domain in Google Search Console
This prevents:
duplicate content
split link equity
crawling inefficiency
ranking issues
How to Implement Proper Redirects
If you choose www, redirect non-www → www:
Example (Apache):
RewriteEngine On RewriteCond %{HTTP_HOST} ^example\.com [NC] RewriteRule ^(.*)$ https://www.example.com/$1 [L,R=301]If you choose non-www, redirect www → non-www:
RewriteCond %{HTTP_HOST} ^www\.example\.com [NC] RewriteRule ^(.*)$ https://example.com/$1 [L,R=301]The same applies for NGINX, Cloudflare, and cPanel.
Conclusion
The debate of www vs non-www comes down to technical needs, brand preference, and long-term scalability — not SEO. Both versions work equally well for ranking, but www offers more flexibility while non-www offers cleaner branding.
Choose based on your project’s needs, then be consistent with your implementation. Proper redirects and Search Console settings matter far more than your chosen domain format.
