Mod Rewrite / .htaccess avoid duplicate content
-
I have been searching and testing for hours but cannot find a solution. I am able to get a URL to display with out the file exntension.
i.e domain.com/file instead of domain.com/file.php
The problem is both versions of the URL above work, therefore a duplicate content issue. How can I force the URL with the file extension not to resolve and give a 404 error? Or just redirect to the non extension URL?
IF it helps here is my code.
Options +FollowSymLinks
RewriteEngine OnRewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteCond %{REQUEST_FILENAME}.php -f
RewriteRule ^(.+)$ $1.php [L,QSA] -
Hi Erik,
No problem, glad I could help
To answer your question, No it doesn't matter which you use because the end result will be re-written to remove the file extension and add a forward slash at the end.
For consistency I would suggest having it without the .php inside your content though. If nothing else it would save you the pain of having to remove .php from your content if you moved to a content management system in the future.
If you've got any other questions let me know, and I'll be happy to help.

Didnt say thanks before, so thank you. One question I did not think of. Should the internal linking of the site be to the file name with extension or no extension?
I think it should be without extension but just want to double check.

Hi Ben. I tried this code on another hosting account and it did worked. The first account was a VPS account from Godaddy. The second was a shared account from the same hosting company. Im not sure why it works on one and not on the other. I did see the mod_rewrite option enabled.

Just tried this on my development server and it worked fine:
RewriteBase / RewriteEngine on RewriteCond %{HTTP_HOST} ^test.local RewriteCond %{THE_REQUEST} ^GET\ (.).php\ HTTP RewriteRule (.).php$ $1 [R=301]
remove index RewriteRule (.*)index$ $1 [R=301]
remove slash if not directory RewriteCond %{REQUEST_FILENAME} !-d RewriteCond %{REQUEST_URI} /$ RewriteRule (.)/ $1 [R=301] # add .php to access file, but don't redirect RewriteCond %{REQUEST_FILENAME}.php -f RewriteCond %{REQUEST_URI} !/$RewriteRule (.) $1.php [L]
The dev URL is test.local so you would want to change this to www.yourdomain.co.ukI had a page called about.php if I entered http://test.local/about.php or http://test.local/about it would show http://test.local/about in the address bar

Hi Ben. Thanks for your help but this does not work for some reason. Im testing it on an old site I have that is html and I just replaced php for html but both URL's still resolves.

Good answer Ben.
My main site is my own CMS, that I built 10 years ago, so after I added a lot of things to the .htaccess file and it became too large, I just moved the handling inside the control program, that only looks up filed URLs when they are broken. This processing is fast, but if there was any degradation, it only affects the broken URLs.
Speaking of broken URLs, I was getting a few 400 return codes and it seems the webserver handles those, so you have no chance to handle it in .htaccess. So the wat to handle that is with a 400 handler - that on cpanel sites just needs a 400.shtml file, that you can customize.
- you get a 400 response if you request a URL with a % symbol on the end, and some other site did that, thanks very much, and then google decided it would be a great thing to index.

Try using this instead:
<code>RewriteBase /</code>
<code># remove .php; use THE_REQUEST to prevent infinite loops
RewriteCond %{HTTP_HOST} ^www.domain.com
RewriteCond %{THE_REQUEST} ^GET\ (.).php\ HTTP
RewriteRule (.).php$ $1 [R=301]remove index
RewriteRule (.*)index$ $1 [R=301]
remove slash if not directory
RewriteCond %{REQUEST_FILENAME} !-d
RewriteCond %{REQUEST_URI} /$
RewriteRule (.*)/ $1 [R=301]add .php to access file, but don't redirect
RewriteCond %{REQUEST_FILENAME}.php -f
RewriteCond %{REQUEST_URI} !/$
RewriteRule (.*) $1.php [L]</code>

Duplicate Content Issues with Pagination
Hi Moz Community, We're an eCommerce site so we have a lot of pagination issues but we were able to fix them using the rel=next and rel=prev tags. However, our pages have an option to view 60 items or 180 items at a time. This is now causing duplicate content problems when for example page 2 of the 180 item view is the same as page 4 of the 60 item view. (URL examples below) Wondering if we should just add a canonical tag going to the the main view all page to every page in the paginated series to get ride of this issue. https://www.example.com/gifts/for-the-couple?view=all&n=180&p=2 https://www.example.com/gifts/for-the-couple?view=all&n=60&p=4 Thoughts, ideas or suggestions are welcome. Thanks

Query Strings causing Duplicate Content
I am working with a client that has multiple locations across the nation, and they recently merged all of the location sites into one site. To allow the lead capture forms to pre-populate the locations, they are using the query string /?location=cityname on every page. EXAMPLE - www.example.com/product www.example.com/product/?location=nashville www.example.com/product/?location=chicago There are thirty locations across the nation, so, every page x 30 is being flagged as duplicate content... at least in the crawl through MOZ. Does using that query string actually cause a duplicate content problem?

Handling of Duplicate Content
I just recently signed and joined the moz.com system. During the initial report for our web site it shows we have lots of duplicate content. The web site is real estate based and we are loading IDX listings from other brokerages into our site. If though these listings look alike, they are not. Each has their own photos, description and addresses. So why are they appear as duplicates – I would assume that they are all too closely related. Lots for Sale primarily – and it looks like lazy agents have 4 or 5 lots and input the description the same. Unfortunately for us, part of the IDX agreement is that you cannot pick and choose which listings to load and you cannot change the content. You are either all in or you cannot use the system. How should one manage duplicate content like this? Or should we ignore it? Out of 1500+ listings on our web site it shows 40 of them are duplicates.

Wordpress categories causing too many links/duplicate content?
I've just added categories to my wordpress site and some of the posts show in several of the categories. Will this cause me duplicate content problems as I want the category pages to be indexed? Also as I add more categories I'm creating more links on the page. They can't be seen to the user as I have a plugin that creates drop down categories. When I go to 'view source' though all the links are there so google will see lots of links. How can I fix the too many links problem? And should I worry about duplicate content issue?

How to prevent duplicate content at a calendar page
Hi, I've a calender page which changes every day. The main url is
Technical SEO | | GeorgFranz
/calendar For every day, there is another url: /calendar/2012/09/12
/calendar/2012/09/13
/calendar/2012/09/14 So, if the 13th september arrives, the content of the page
/calendar/2012/09/13
will be shown at
/calendar So, it's duplicate content. What to do in this situation? a) Redirect from /calendar to /calendar/2012/09/13 with 301? (but the redirect changes the day after to /calendar/2012/09/14) b) Redirect from /calendar to /calendar/2012/09/13 with 302 (but I will loose the link juice of /calendar?) c) Add a canonical tag at /calendar (which leads to /calendar/2012/09/13) - but I will loose the power of /calendar (?) - and it will change every day... Any ideas or other suggestions? Best wishes, Georg.0 -
Duplicate Content and URL Capitalization
I have multiple URLs that SEOMoz is reporting as duplicate content. The reason is that there are characters in the URL that may, or may not, be capitalized depending on user input. A couple examples are: www.househitz.com/Pennsylvania/Houses-for-sale www.househitz.com/Pennsylvania/houses-for-sale www.househitz.com/Pennsylvania/Houses-for-rent www.househitz.com/Pennsylvania/houses-for-rent There are currently thousands of instances of this on the site. Is this something I should spend effort to try and resolve (may not be minor effort), or should I just ignore it and move on?

My .htaccess has changed, what do i do to avoid it again...?
Hello Today i notice that our site did not auto changed from without www to with, when i checked the .htaccess file i notice # in-front of each line and i know we did not insert it in there, after i removed it it worked fine. The only changes that we did recently was to a mobile version to the site but the call to autodirect is in a JS and not in the .htaccess, could it be the server..? is there any way that anything else might cause this...? The site is HTML and WP could it be because of that...? Thank's Simo

Using video transcripts v captions and avoiding duplicate content?
Part 1: After editing a You Tube transcript, I typically re-upload as a caption file (with time codes)...for SEO does it matter whether you upload as a transcript v. captions? Is one better than the other? Part 2: If you upload a transcript (or caption) to YouTube, then post that video/transcript in your blog, wouldn't you get pinged for duplicate content?
