Launching a website is the easy part.
Building it correctly underneath is what really matters. Domain structure is one of the most overlooked but critical technical decisions.
The same website accessible from multiple URLs is a problem.
For example:
-
domain.com.tr version
Search engines treat these as separate addresses unless you clearly tell them otherwise. If you don’t consolidate them properly, authority gets split, indexing becomes inconsistent, and rankings suffer.
The solution is simple:
Choose one canonical domain and redirect everything to it using 301.
My preferred structure in most projects:
No www. No http. No alternative extensions. One clean address.
Why 301?
A 301 redirect means permanent.
You’re telling search engines:
“This content lives here now.”
If you use 302 (temporary), SEO value does not properly transfer. For domain migrations, removing www, or switching extensions, 301 is mandatory.
Redirecting .com.tr to .com
A common mistake is keeping both .com and .com.tr active with identical content. That creates duplicate content issues.
The correct setup:
All traffic from:
domain.com.tr
→ redirect to
https://domain.com
And it must preserve full paths.
/about should become /about, not just the homepage.
The www Question
Technically, www is just a subdomain.
There is no SEO advantage between www and non-www. What matters is consistency.
Pick one.
Redirect the other permanently.
Done.
HTTPS Is Not Optional
There is no reason to run HTTP anymore.
Security and SEO both require HTTPS.
Every HTTP request should go directly to the final HTTPS version. Avoid redirect chains.
Bad setup:
http → https → www → non-www
Correct setup:
Directly → https://domain.com
Final Thoughts
A clean domain architecture means:
-
One canonical address
-
Permanent 301 redirects
-
Mandatory HTTPS
-
www consistency
-
Alternative extensions consolidated
You configure it once, correctly, and you don’t touch it again.
Most performance and SEO issues don’t come from code. They come from structural misconfiguration. Domain redirection may look minor, but it’s one of the foundations of a healthy website.
