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.

410 or 301 after URL update?
Hi there, A site i'm working on atm has a thousand "not found" errors on google console (of course, I'm sure there are thousands more it's not showing us!). The issue is a lot of them seem to come from a URL change. Damage has been done, the URLs have been changed and I can't stop that... but as you can imagine, i'm keen to fix as many as humanly possible. I don't want to go mad with 301s - but for external links in, this seems like the best solution? On the other hand, Google is reading internal links that simply aren't there anymore. Is it better to hunt down the new page and 301-it anyway? OR should I 410 and grit my teeth while google crawls and recrawls it, warning me that this page really doesn't exist? Essentially I guess I'm asking, how many 301s are too many and will affect our DA? And what's the best solution for dealing with mass 404 errors - many of which aren't attached or linked to from any other pages anymore? Thanks for any insights 🙂

Best Practices for Title Tags for Product Listing Page
My industry is commercial real estate in New York City. Our site has 300 real estate listings. The format we have been using for Title Tags are below. This probably disastrous from an SEO perspective. Using number is a total waste space. A few questions:
Intermediate & Advanced SEO | | Kingalan1
-Should we set listing not no index if they are not content rich?
-If we do choose to index them, should we avoid titles listing Square Footage and dollar amounts?
-Since local SEO is critical, should the titles always list New York, NY or Manhattan, NY?
-I have red that titles should contain some form of branding. But our company name is Metro Manhattan Office Space. That would take up way too much space. Even "Metro Manhattan" is long. DO we need to use the title tag for branding or can we just focus on a brief description of page content incorporating one important phrase? Our site is: w w w . m e t r o - m a n h a t t a n . c o m <colgroup><col width="405"></colgroup>
| Turnkey Flatiron Tech Space | 2,850 SF $10,687/month | <colgroup><col width="405"></colgroup>
| Gallery, Office Rental | Midtown, W. 57 St | 4441SF $24055/month | <colgroup><col width="405"></colgroup>

Help with facet URLs in Magento
Hi Guys, Wondering if I can get some technical help here... We have our site britishbraces.co.uk , built in Magento. As per eCommerce sites, we have paginated pages throughout. These have rel=next/prev implemented but not correctly ( as it is not in is it in ) - this fix is in process. Our canonicals are currently incorrect as far as I believe, as even when content is filtered, the canonical takes you back to the first page URL. For example, http://www.britishbraces.co.uk/braces/x-style.html?ajaxcatalog=true&brand=380&max=51.19&min=31.19 Canonical to... http://www.britishbraces.co.uk/braces/x-style.html Which I understand to be incorrect. As I want the coloured filtered pages to be indexed ( due to search volume for colour related queries ), but I don't want the price filtered pages to be indexed - I am unsure how to implement the solution? As I understand, because rel=next/prev implemented ( with no View All page ), the rel=canonical is not necessary as Google understands page 1 is the first page in the series. Therefore, once a user has filtered by colour, there should then be a canonical pointing to the coloured filter URL? ( e.g. /product/black ) But when a user filters by price, there should be noindex on those URLs ? Or can this be blocked in robots.txt prior? My head is a little confused here and I know we have an issue because our amount of indexed pages is increasing day by day but to no solution of the facet urls. Can anybody help - apologies in advance if I have confused the matter. Thanks

Will disallowing URL's in the robots.txt file stop those URL's being indexed by Google
I found a lot of duplicate title tags showing in Google Webmaster Tools. When I visited the URL's that these duplicates belonged to, I found that they were just images from a gallery that we didn't particularly want Google to index. There is no benefit to the end user in these image pages being indexed in Google. Our developer has told us that these urls are created by a module and are not "real" pages in the CMS. They would like to add the following to our robots.txt file Disallow: /catalog/product/gallery/ QUESTION: If the these pages are already indexed by Google, will this adjustment to the robots.txt file help to remove the pages from the index? We don't want these pages to be found.

Image URLs - best practice
Hi - I'm assuming image URL best practice follows same principles as non image URLs (not too many files and so on) - I notice alot of web devs putting photos in subdomains, so wonder if I'm missing something (I usually avoid subdomains like the plague)!

Replace dynamic paramenter URLs with static Landing Page URL - faceted navigation
Hi there, got a quick question regarding faceted navigation. If a specific filter (facet) seems to be quite popular for visitors. Does it make sense to replace a dynamic URL e.x http://www.domain.com/pants.html?a_type=239 by a static, more SEO friendly URL e.x http://www.domain.com/pants/levis-pants.html by creating a proper landing page for it. I know, that it is nearly impossible to replace all variations of this parameter URLs by static ones but does it generally make sense to do this for the most popular facets choose by visitors. Or does this cause any issues? Any help is much appreciated. Thanks a lot in advance

Is it safe to redirect multiple URLs to a single URL?
Hi, I have an old Wordress website with about 300-400 original pages of content on it. All relating to my company's industry: travel in Africa. It's a legitimate site with travel stories, photos, advice etc. Nothing spammy about. No adverts on it. No affiliates. The site hasn't been updated for a couple of years and we no longer have a need for it. Many of the stories on it are quite out of date. The site has built up a modest Mozrank value over the last 5 years, and has a few hundreds organically achieved inbound links. Recently I set up a swanky new branded website on ExpressionEngine on a new domain. My intention is to: Shut down the old site Focus all attention on building up content on the new website Ask the people linking to the old site to my new site instead (I wonder how many will actually do so...) Where possible, setup a 301 redirect from pages on the old site to their closest match on the new site Setup a 301 redirect from the old site's home page to new site's homepage Sounds good, right? But there is one issue I need some advice on... The old site has about 100 pages that do not have a good match on the new site. These pages are outdated or inferior quality, so it doesn't really make sense to rewrite them and put them on the new site. I call these my "black sheep pages". So... for these "black sheep pages" should I (A) redirect the urls to the new site's homepage (B) redirect the urls the old site's home page (which in turn, redirects to the new site's homepage, or (C) not redirect the urls, and let them die a lonely 404 death? OPTION A: oldsite.com/page1.php -> newsite.com
Intermediate & Advanced SEO | | AndreVanKets
oldsite.com/page2.php -> newsite.com
oldsite.com/page3.php -> newsite.com
oldsite.com/page4.php -> newsite.com
oldsite.com/page5.php -> newsite.com
oldsite.com -> newsite.com OPTION B: oldsite.com/page1.php -> oldsite.com
oldsite.com/page2.php -> oldsite.com
oldsite.com/page3.php -> oldsite.com
oldsite.com/page4.php -> oldsite.com
oldsite.com/page5.php -> oldsite.com
oldsite.com -> newsite.com OPTION 😄 oldsite.com/page1.php : do not redirect, let page 404 and disappear forever
oldsite.com/page2.php : do not redirect, let page 404 and disappear forever
oldsite.com/page3.php : do not redirect, let page 404 and disappear forever
oldsite.com/page4.php : do not redirect, let page 404 and disappear forever
oldsite.com/page5.php : do not redirect, let page 404 and disappear forever
oldsite.com -> newsite.com My intuition tells me that Option A would pass the most "link juice" to my new site, but I am concerned that it could also be seen by Google as a spammy redirect technique. What would you do? Help 😐1
