URL Rewriting Best Practices
-
Hey Moz!
I’m getting ready to implement URL rewrites on my website to improve site structure/URL readability. More specifically I want to:
- Improve our website structure by removing redundant directories.
- Replace underscores with dashes and remove file extensions for our URLs.
Please see my example below:
Old structure: http://www.widgets.com/widgets/commercial-widgets/small_blue_widget.htm
New structure: https://www.widgets.com/commercial-widgets/small-blue-widget
I've read several URL rewriting guides online, all of which seem to provide similar but overall different methods to do this. I'm looking for what's considered best practices to implement these rewrites. From what I understand, the most common method is to implement rewrites in our .htaccess file using mod_rewrite (which will find the old URLs and rewrite them according to the rewrites I implement).
One question I can't seem to find a definitive answer to is when I implement the rewrite to remove file extensions/replace underscores with dashes in our URLs, do the webpage file names need to be edited to the new format? From what I understand the webpage file names must remain the same for the rewrites in the .htaccess to work. However, our internal links (including canonical links) must be changed to the new URL format. Can anyone shed light on this?
Also, I'm aware that implementing URL rewriting improperly could negatively affect our SERP rankings. If I redirect our old website directory structure to our new structure using this rewrite, are my bases covered in regards to having the proper 301 redirects in place to not affect our rankings negatively?
Please offer any advice/reliable guides to handle this properly.
Thanks in advance!

Thanks for clearing that up and all of the help!

I'm saying rename files first and do rewrite for removing extensions.
You will have to do rewrite for replacing underscores with hyphens anyway, just for redirect purposes.
So, rename files from underscores to hyphens; do rewrite rule for underscore to hyphens to insure old pages are being redirected; do another rewrite for removing file extensions. In som time (2-3-4 months) when old file names (with underscores) are out of google index, delete first rewrite.

Hey Dmitrii,
I was planning on using two rewrites.
One rewrite for replacing the underscores with hyphens.
And another rewrite for removing the file extensions.
Just so I fully understand, you recommend implementing the rewrite for replacing the underscores with hyphens in our .htaccess file. Then once the new URLs are indexed, change the webpage file names themselves by replacing the underscores with hyphens, make the newly named files live and remove this rewrite from our .htaccess. Is my understanding correct?
Again...thanks for all of your help!

Well, I thought that's what you were going to do and use rewrite just for deleting file extensions. Honestly, I'd leave file extensions and rename files to hyphens. This way there is no server processing involved.
-
Another question just popped into my head...
Once our new website directory structure and URL format has been rewritten, redirected and indexed by search engines, would it make sense to edit the actual webpage file names (replacing the underscores w/ hyphens) and then remove the URL rewrite that replaces the underscores with the hyphens? Or is this not recommended?

Thanks for the help Dmitrii!
Both the rewrite I posted above and yours for removing file extensions failed to work. However, it seems this one does the trick (taken from the Apache help forums).
RewriteCond %{THE_REQUEST} ^[A-Z]{3,}\s([^.]+).htm [NC,OR]
RewriteCond %{THE_REQUEST} ^[A-Z]{3,}\s([^.]+).php [NC]
RewriteRule ^ %1 [R,L] -
Yes, I believe so, that's the only rewrite you'd need not to mess up rankings.
I don't know if one of codes is better than another. All I know that my piece of code is working and i haven't used the one you wrote. It seems ok to me, but just test it. If it works, I don't think there is any difference.

Hey Dmitrii,
This rewrite that I posted above...
RewriteRule ^old/(.*)$ /new/$1 [L,R=301]
...isn't intended to remove the file extensions. I'm using it to redirect the old directory structure to our new directory structure.
I was asking if using this rewrite when changing my directory structure will be all I need in regards to having all the necessary redirects in place to not negatively affect our SEO/SERP rankings. Any idea?
Also, would you recommend the rewrite you provided above over the one below when removing file extensions?
RewriteBase /
RewriteEngine on
RewriteCond %{REQUEST_FILENAME} !-d
RewriteCond %{REQUEST_FILENAME}.html -f
RewriteRule ^(.*)$ $1.htmlLet me know if I'm being clear enough
Thanks!

the rule you wrote wont work.
What it will do is redirect this: _domain.com/old/small_blue_widget.htm _to this: domain.com/new/small_blue_widget.htm
To remove the extension would be:
<code>RewriteRule ^([^\.]+)$ $1.htm [NC,L]</code>
-
Thanks for the response Dmitrii!
Thanks for for confirming that I don't need to update the webpage file names.
Do you know if redirecting the old directories to the new ones (using the the rewrite below) is all I need to do regarding redirects? In other words, when redirecting directories using the rewrite below is there any need to redirect the old URL format (small_blue_widget.htm) to the new (small-blue-widget)? My understanding is no, all I need to do is redirect the directories; but please share your knowledge.Thanks in advance!
<code>RewriteRule ^old/(.*)$ /new/$1 [L,R=301]</code>

Hi there.
Well, as for best practices - you got it covered - remove/substitute underscores, remove redundant directories, make urls readable and understandable by users, implement redirects for pages, which are being renamed.
As for removing extensions from files - i'm not sure it has any effect on SEO or user experience at all. But no, you don't have to create new format pages. Basically what mod_rewrite does is when somebody requests a page, server says "I gonna server you this file with this name, because you sent me this specific request". Just be aware that there is no way to access both original url and rewritten url at the same time, since it would create duplicate issues.
As for rankings affect - as long as all redirects are done properly and urls are targeting the keywords on the page - you should be fine.

URL Construction
Working on an old site that currently has category urls (that productively rank) like this example: LakeNameBoating.com/category/705687/rentals I want to enhance the existing mid page one rank for terms related to "Lake Name Boat Rentals," 301ing the old urls to the new, would you construct the new urls as: LakeNameBoating.com/lake-name-boat-rentals or... LakeNameBoating.com/boat-rentals And why? It's all for one particular lake with "name" being just an anonymous placeholder example. Thanks!

Redirect to url with parameter
I have a wiki (wiki 1) where many of the pages are well index in google. Because of a product change I had to create a new wiki (wiki 2) for the new version of my product. Now that most of my customers are using the new version of my product I like to redirect the user from wiki 1 to wiki 2. An example of a redirect could be from wiki1.website.com/how_to_build_kitchen to wiki2.website.com/how_to_build_kitchen. Because of a technical issue the url I redirect to, needs to have a parameter like "?" so the example will be wiki2.website.com/how_to_build_kitchen? Will the search engines see it as I have two pages with same content?

wiki2.website.com/how_to_build_kitchen
and
wiki2.website.com/how_to_build_kitchen? And will the SEO juice from wiki1.website.com/how_to_build_kitchen be transfered to wiki2.website.com/how_to_build_kitchen?0 -
Duplicate content URLs from bespoke ecommerce CMS - what's the best solution here?
Hi Mozzers Just noticed this pattern on a retail website... This URL product.php?cat=5 is also churning out products.php?cat=5&sub_cat= (same content as product.php?cat=5 but from this different URL - this is a blank subcat - there are also unique subcat pages with unique content - but this one is blank) How should I deal with that? and then I'm seeing: product-detail.php?a_id=NT001RKS0000000 and product-detail.php?a_id=NT001RKS0000000&cont_ref=giftselector (same content as product-detail.php?a_id=NT001RKS0000000 but from this different URL) How should I deal with that? This is a bespoke ecommerce CMS (unfortunately). Any pointers would be great 🙂 Best wishes, Luke

Urls in Bilingual websites
1-I have a bilingual website. Suppose that I am targeting a page for keyword "book" and I have included it in that page url for the English version: English version: www.abc.com/book Can I use the translation of "book" in the second language of the website url instead of "book" ? Please let me know which of the following urls are right " French Verison: www.abc.com/fr/book or www.abc.com/fr/livre livre=Book in French 2- Does Google have any tool to check if the second language page of the website has exactly the same content as the English version. What I want to do is for example for a certain page in English version, my targeted keyword is "book" . So my content would be around books. But in the French version of this page, I want to focus on keyword "Pencil" in French instead of "book". Is it wrong or any consequences? That was the main reason for the question number one. Because if it is ok to do what I explained in item 2 then I will set my urls like: In English : www.abc.com/book In French: www.abc.com/fr/crayon crayon=Pencil in French

Tagged URL ranking organically
I've noticed that one of our GA tagged urls are ranking organically & therefore is skewing the referral data. The campaign that we were tracking is no longer active but the link still works, but it's going to an old landing page. I asked our developers if we could redirect it but they said that it didn't work. Does anyone have some advise or a solution for this? Thanks!

Best Practices for Pagination on E-commerce Site
One of my e-commerce clients has a script enabled on their category pages that allows more products to automatically be displayed as you scroll down. They use this instead of page 1, 2, and a view all. I'm trying to decide if I want to insist that they change back to the traditional method of multiple pages with a view all button, and then implement rel="next", rel="prev", etc. I think the current auto method is disorienting for the user, but I can't figure out if it's the same for the spiders. Does anyone have any experience with this, or thoughts? Thanks!
