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 URL structures with multiple filter combinations
Hello, We're putting together a large piece of content that will have some interactive filtering elements. There are two types of filters, topics and object types. The architecture under the hood constrains us so that everything needs to be in URL parameters. If someone selects a single filter, this can look pretty clean: www.domain.com/project?topic=firstTopic
Intermediate & Advanced SEO | | digitalcrc
or
www.domain.com/project?object=typeOne The problems arise when people select multiple topics, potentially across two different filter types: www.domain.com/project?topic=firstTopic-secondTopic-thirdTopic&object=typeOne-typeTwo I've raised concerns around the structure in general, but it seems to be too late at this point so now I'm scratching my head thinking of how best to get these indexed. I have two main concerns: A ton of near-duplicate content and hundreds of URLs being created and indexed with various filter combinations added Over-reacting to the first point above and over-canonicalizing/no-indexing combination pages to the detriment of the content as a whole Would the best approach be to index each single topic filter individually, and canonicalize any combinations to the 'view all' page? I don't have much experience with e-commerce SEO (which this problem seems to have the most in common with) so any advice is greatly appreciated. Thanks!0 -
How To Organise my URLS - Which is Optimal?
Hi all, I am currently in the process of re-writing my companies website URL structure. Compared to the way the website is structured at the minute, there's going to be a lot more URL's as the previous structure has missed out on a lot of search avenues that i intend to include within the rebuild. one of my issues is basically deciding under which category certain URL's come under, I can think of reasons for both sides but can't quite decide on which is optimal. My company is an automotive/car dealer so we sell cars for certain manufactures as well as offering a number of other services. what I'm curious about is what makes more sense in terms of the category that comes first in the URL. Here's what I am torn between; /(car manufacturer)/servicing OR /servicing/(car-manufacturer) To give you some more info that might influence the decision; In terms of generic keyword targeting, the majority would search in the order of '(car manufacturer) service' as opposed to 'service for (car manufacturer)'. Currently on our site, the sections /(manufacturer) are some of the most authoritative pages that we have on the website, but we've done very little work on /service in the past. For me, this would suggest that naturally the pages flowing from that URL would get an advantage in terms of authority/ranking. With either URL structure, the URL's are eventually going to cross paths - I just need to decide which one is best and should therefore feature first. Hopefully this is somewhat clear. I'd appreciate any suggestions or if you don't quite understand what I'm asking for then general URL advice is also appreciated. Many thanks Sam

Are Incorrectly Set Up URL Rewrites a Possible Cause of Panda
On a .NET site, there was a url rewrite done about 2 years ago. From a visitor's perspective, it seems to be fine as the urls look clean. But, Webmaster tools reports 500 errors from time to time showing /modules/categories... and /modules/products.... which are templates and how the original urls were structured. While the developer made it look clean, I am concerned that he could have set it up incorrectly. He acknowledged that IIS 7 on a Windows server allows url rewrites to be set up, but the site was done in another way that forces the urls to change to their product name. So, he has believed it to be okay. However, the site dropped significantly in its ranking in July 2013 which appears to be a Panda penalty. In trying to figure out if this could be a factor in why the site has suffered, I would like to know other webmasters opinions. We have already killed many pages, removed 2/3 of the index that Google had, and are trying to understand what else it could be. Also, in doing a header check, I see that it shows the /modules/products... page return a 301 status. I assume that this is okay, but wanted to see what others had to say about this. When I look at the source code of a product page, I see a reference to the /modules/products... I'm not sure if any of this pertains, but wanted to mention in case you have insight. I hope to get good feedback and direction from SEOs and technical folks

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!

Should we use URL parameters or plain URL's=
Hi, Me and the development team are having a heated discussion about one of the more important thing in life, i.e. URL structures on our site. Let's say we are creating a AirBNB clone, and we want to be found when people search for apartments new york. As we have both have houses and apartments in all cities in the U.S it would make sense for our url to at least include these, so clone.com/Appartments/New-York but the user are also able to filter on price and size. This isn't really relevant for google, and we all agree on clone.com/Apartments/New-York should be canonical for all apartment/New York searches. But how should the url look like for people having a price for max 300$ and 100 sqft? clone.com/Apartments/New-York?price=30&size=100 or (We are using Node.js so no problem) clone.com/Apartments/New-York/Price/30/Size/100 The developers hate url parameters with a vengeance, and think the last version is the preferable one and most user readable, and says that as long we use canonical on everything to clone.com/Apartments/New-York it won't matter for god old google. I think the url parameters are the way to go for two reasons. One is that google might by themselves figure out that the price parameter doesn't matter (https://support.google.com/webmasters/answer/1235687?hl=en) and also it is possible in webmaster tools to actually tell google that you shouldn't worry about a parameter. We have agreed to disagree on this point, and let the wisdom of Moz decide what we ought to do. What do you all think?

Dynamic URLs Appearing on Google Page 1\. Convert to Static URLs or not?
Hi, I have a client who uses dynamic URLs thoughout his site. For SEO purposes, I've advised him to convert dynamic URLs to static URLs whenever possible. However, the client has a few dynamic URLs that are appearing on Google Page 1 for strategically valuable keywords. For these URLs, is it still worth it to 301 them to static URLs? In this case, what are the potential benefits and/or pitfalls?
