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.

Site-wide Canonical Rewrite Rule for Multiple Currency URL Parameters?
Hi Guys, I am currently working with an eCommerce site which has site-wide duplicate content caused by currency URL parameter variations. Example: https://www.marcb.com/ https://www.marcb.com/?setCurrencyId=3 https://www.marcb.com/?setCurrencyId=2 https://www.marcb.com/?setCurrencyId=1 My initial thought is to create a bunch of canonical tags which will pass on link equity to the core URL version. However I was wondering if there was a rule which could be implemented within the .htaccess file that will make the canonical site-wide without being so labour intensive. I also noticed that these URLs are being indexed in Google, so would it be worth setting a site-wide noindex to these variations also? Thanks

What are the best practices for geo-targeting by sub-folders?
My domain is currently targeting the US, but I'm building out sub-folders that will need to geo-target France, England, and Spain. Each country will have it's own sub-folder, and professionally translated (domain.com/france). Other than the hreflang tags, what are other best practices I can implement? Can Google Webmaster tools geo-target by subfolder? Any suggestions would be appreciated. Thanks Justin

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?

Membership/subscriber (/customer) only content and SEO best practice
Hello Mozzers, I was wondering whether there's any best practice guidance out there re: how to deal with membership/subscriber (existing customer) only content on a website, from an SEO perspective - what is best practice? A few SEOs have told me to make some of the content visible to Google, for SEO purposes, yet I'm really not sure whether this is acceptable / manipulative, and I don't want to upset Google (or users for that matter!) Thanks in advance, Luke

Domain Name Change - Best Practices?
Good day guys, We got a restaurant that is changing its name and domain. However they are keeping the same server location, same content and same pages (we are just changing the logo on the website). It just has to go a new domain. We don't want to lose the value of the current site, and we want to avoid any duplicate penalties. Could you please advise of the best practices of doing a domain name change? Thank you.

Best Practice for Inter-Linking to CCTLD brand domains
Team, I am wondering what people recommend as best SEO practice to inter-link to language specific brand domains e.g. : amazon.com
Intermediate & Advanced SEO | | tomypro
amazon.de
amazon.fr
amazon.it Currently I have 18 CCTLDs for one brand in different languages (no DC). I am linking from each content page to each other language domain, providing a link to the equivalent content in a separate language on a different CCTLD doamin. However, with Google's discouragement of site-wide links I am reviewing this practice. I am tending towards making the language redirects on each page javascript driven and to start linking only from my home page to the other pages with optimized link titles. Anyone having any thoughts/opinions on this topic they are open to sharing? /Thomas0 -
Exact keyword URL or not?
Hi all, I have a quick question about the proper use of permalinks. Let's say that I have a website about sports and I want to create an internal page dedicated to shoes. I know that the keyword "shoe" has 15.000 monthly visits, while the keyword "shoes" has 1.000 monthly visits. How do I have to name the internal page? http://www.example.com/shoe or http://www.example.com/shoes (with a final 's')? I would think that by naming the URL http://www.example.com/shoes, the search engine would consider that page for the keywords "shoe" and "shoes", but I am not sure about it. Should I create a URL that only focuses on one specific keyword ("shoe", in this example) or a URL that may encompass more than one keyword ("shoe" and "shoes")? I hope this is clear. Thank you for your time and help. All best, Sal
