Enter a URL
I want you to try a very simple experiment right now. Open a new tab in your browser and type in your website address including the "www" (for example: http://www.yourdomain.com). Now, open a second tab, but this time, completely delete the "www" and just type http://yourdomain.com.
Did the website load perfectly on both tabs? Did the address bar in your browser stay exactly the way you typed it in both tabs?
If you answered yes, you might think everything is working flawlessly. You probably think it's great that your customers can reach your website no matter how they type it into the search bar. The brutal reality? You have just committed one of the most destructive technical errors in the entire SEO rulebook.
To you, those two addresses are the exact same thing. But to Google, they are two completely different websites. Because both websites are loading the exact same articles, Google's algorithm assumes you are running a massive plagiarism scheme. You are currently being penalized for Duplicate Content. You must fix this immediately, and that is exactly why we built the RankZoa WWW Redirect Checker.
In the eyes of a search engine spider, the "www" is technically considered a subdomain. It is treated as a completely separate entity from the root domain. If you do not explicitly tell the server to merge them together, you suffer from a split personality disorder.
This causes two catastrophic problems for your rankings:
1. The Duplicate Content Penalty
Google absolutely hates duplicate content. Their goal is to show searchers a wide variety of unique answers. If their spider crawls www.yoursite.com/blog and then crawls yoursite.com/blog, it sees two identical copies of the exact same article. Google doesn't know which one is the "real" one, so it gets confused, flags them both as spam, and refuses to rank either of them.
2. Splitting Your Link Juice in Half
Let's say you spend a year building 100 high-quality backlinks to your website. If 50 bloggers linked to your "www" address, and 50 bloggers linked to your "non-www" address, your SEO power is effectively cut in half. Neither version of your website is strong enough to beat your competitors because your ranking power is split between two different buckets.
You have to pick a winner. You must decide whether you want your official website to be the WWW version, or the Non-WWW version. (It doesn't matter which one you pick, you just have to pick one).
Once you pick your master version, you must set up a 301 Permanent Redirect on your web server. If you pick the WWW version, the redirect acts as a digital bouncer. Anytime a user (or Googlebot) tries to visit the Non-WWW version, the server instantly and invisibly teleports them over to the WWW version.
When Googlebot hits that 301 Redirect, it is a massive signal. It tells the spider, "Hey, this page has moved permanently. Please take all the ranking power and link juice from this old address and pour it directly into the master address." Your split personality is cured. Your SEO power is consolidated into one massive bucket.
You cannot just guess if your web developer set up the redirects correctly. You need hard, mathematical proof that the server is broadcasting the correct HTTP Status Code.
Which version is actually better for SEO: WWW or Non-WWW?
From a pure SEO ranking perspective, Google does not care at all. It is a purely aesthetic choice. Most modern tech startups and modern blogs prefer the "Non-WWW" version because it looks cleaner and shorter on business cards and social media profiles. However, massive, complex corporate websites often prefer the "WWW" version for technical reasons regarding DNS records and cookie management across multiple subdomains. Pick whichever one you think looks better and stick to it permanently.
What is the difference between a 301 Redirect and a 302 Redirect?
This is a critical distinction. A 301 Redirect means "Moved Permanently." It tells Google to transfer all your hard-earned SEO power to the new URL. A 302 Redirect means "Moved Temporarily." It tells Google, "I am doing some maintenance, I will be right back, do NOT transfer my SEO power." If you run our tool and it shows you are using a 302 Redirect for your WWW problem, you are bleeding SEO power and must change it to a 301 immediately.
How do I actually set up the redirect?
The easiest way is usually to log into your web hosting control panel (like cPanel) and use the built-in "Redirects" tool to point the domains. Alternatively, if your server uses Apache, you can manually add a few lines of code to your hidden .htaccess file. If you use a proxy like Cloudflare, you can set up a simple "Page Rule" to handle the WWW redirect automatically before the traffic even hits your server.
What about HTTPS (SSL Certificates)?
In the modern internet, fixing your WWW redirect is only half the battle. You must also force all unsecured "HTTP" traffic to redirect to your secured "HTTPS" URL. A perfectly configured server will instantly route any combination of WWW or HTTP directly to the single, secured master URL.
Stop cannibalizing your own search rankings. Run your domain through the RankZoa WWW Redirect Checker right now and ensure your website is unified, consolidated, and SEO-friendly.
