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.

Best practice for deindexing large quantities of pages
We are trying to deindex a large quantity of pages on our site and want to know what the best practice for doing that is. For reference, the reason we are looking for methods that could help us speed it up is we have about 500,000 URLs that we want deindexed because of mis-formatted HTML code and google indexed them much faster than it is taking to unindex them unfortunately. We don't want to risk clogging up our limited crawl log/budget by submitting a sitemap of URLs that have "noindex" on them as a hack for deindexing. Although theoretically that should work, we are looking for white hat methods that are faster than "being patient and waiting it out", since that would likely take months if not years with Google's current crawl rate of our site.

Are these URL hashtags an SEO issue?
Hi guys - I'm looking at a website which uses hashtags to reveal the relevant content So there's page intro text which stays the same... then you can click a button and the text below that changes So this is www.blablabla.com/packages is the main page - and www.blablabla.com/packages#firstpackage reveals first package text on this page - www.blablabla.com/packages#secondpackage reveals second package text on this same page - and so on. What's the best way to deal with this? My understanding is the URLs after # will not be indexed very easily/atall by Google - what is best practice in this situation?

Linking to URLs With Hash (#) in Them
How does link juice flow when linking to URLs with the hash tag in them? If I link to this page, which generates a pop-over on my homepage that gives info about my special offer, where will the link juice go to? homepage.com/#specialoffer Will the link juice go to the homepage? Will it go nowhere? Will it go to the hash URL above? I'd like to publish an annual/evergreen sort of offer that will generate lots of links. And instead of driving those links to homepage.com/offer, I was hoping to get that link juice to flow to the homepage, or maybe even a product page, instead. And just updating the pop over information each year as the offer changes. I've seen competitors do it this way but wanted to see what the community here things in terms of linking to URLs with the hash tag in them. Can also be a use case for using hash tags in URLs for tracking purposes maybe?

Best practice for retiring old product pages
We’re a software company. Would someone be able to help me with a basic process for retiring old product pages and re-directing the SEO value to new pages. We are retiring some old products to focus on new products. The new software has much similar functionality to the old software, but has more features. How can we ensure that the new pages get the best start in life? Also, what is the best way of doing this for users? Our plan currently is to: Leave the old pages up initially with a message to the user that the old software has been retired. There will also be a message explaining that the user might be interested in one of our new products and a link to the new pages. When traffic to these pages reduces, then we will delete these pages and re-direct them to the homepage. Has anyone got any recommendations for how we could approach this differently? One idea that I’m considering is to immediately re-direct the old product pages to the new pages. I was wondering if we could then provide a message to the user explaining that the old product has been retired but that the new improved product is available. I’d also be interested in pointing the re-directs to the new product pages that are most relevant rather than the homepage, so that they get the value of the old links. I’ve found in the past that old retirement pages for products can outrank the new pages as until you 301 them then all the links and authority flow to these pages. Any help would be very much appreciated 🙂

E-commerce site, one product multiple categories best practice
Hi there, We have an e-commerce shopping site with over 8000 products and over 100 categories. Some sub categories belong to multiple categories - for example, A Christmas trees can be under "Gardening > Plants > Trees" and under "Gifts > Holidays > Christmas > Trees" The product itself (example: Scandinavian Xmas Tree) can naturally belong to both these categories as well. Naturally these two (or more) categories have different breadcrumbs, different navigation bars, etc. From an SEO point of view, to avoid duplicate content issues, I see the following options: Use the same URL and change the content of the page (breadcrumbs and menus) based on the referral path. Kind of cloaking. Use the same URL and display only one "main" version of breadcrumbs and menus. Possibly add the other "not main" categories as links to the category / product page. Use a different URL based on where we came from and do nothing (will create essentially the same content on different urls except breadcrumbs and menus - there's a possibiliy to change the category text and page title as well) Use a different URL based on where we came from with different menus and breadcrumbs and use rel=canonical that points to the "main" category / product pages This is a very interesting issue and I would love to hear what you guys think as we are finalizing plans for a new website and would like to get the most out of it. Thank you all!

Removing dashes in our URLs?
Hi Forum, Our site has an errant product review module that is resulting in about 9-10 404 errors per day on Google Webmaster Tools. We've found that by changing our product page URLs to only include 2 dashes, the module stops causing 404 errors for that page. Does changing our URL from "oursite.com/girls-pink-yoga-capri.html" to "oursite.com/girlspink-yoga-capri.html" hurt our SEO for a search for "girls pink yoga capri"? If so, by how much (assuming everthing else on the page is optimized properly) Thanks for your input.
