Does rewriting a URL affect the page authority?
- 
					
					
					
					
 Hi all, I recently optimized an overview page for a car rental website. Because the page didn’t rank very well, I rewrote the URL, putting the exact keyword combination in it. Then I asked Google to re-crawl the URL through Search Console. This afternoon, I checked Open Site Explorer and saw that the Page Authority had decreased to 1, while the subpages still have an authority of about 18-20. Hence my question: is rewriting a URL a bad idea for SEO? Thank you, 
 Lise

 Page Authority is just a marketing metric made by Moz and won't update until they re-run their index, which I believe is still on a ~monthly timeline. Just because Moz says a page temporarily has a PA of 1 doesn't mean Google sees it that way. If you have a good reason to change a URL structure, feel free to do it as long as you have 301s. Do not change your URL structure for small, un-needed reasons, such as cramming a slightly better KW variation in the URL.

 I do work with a CMS that automatically creates a redirect, but maybe something went wrong, since the authority didn't pass. Thanks for your help!

 Hi Lise, Generally this isn't something you should do unless you just made the page and you want to change it (as in the case of a misspelling in the URL, for example). Like Andy mentioned, you're essentially just creating another page from scratch. I'd also suggest creating a 301 redirect from the old page to the new one. This way any link equity remains intact. Here's a good Moz post on this topic: https://a-moz.groupbuyseo.org/blog/should-i-change-my-urls-for-seo

 Hello, There is no problem to rewrite URLs, but you may have good reason and make sure 301 are ok. For example on my website about comparative garages, if a garage sells its company to another one, and the name change, we keep the same ID in database but we change the name : from garage-name1-1234.html to garage-name2-1234.html, to keep the history from google because it's the same location, but we change the name to alert Google that there was a big change.

 Hi, I believe that some CMS will automatically do the 301 redirect for you if you rewrite a URL (you can easily check this using this tool: https://httpstatus.io/ . If it does automatically 301 redirect the old to the new then you should be OK as the majority of your page authority will pass onto the new URL. But without doing redirects, as Andy said, you wil lose the page authority.

 Hi Lise, It isn't best to do this because Google won't give you any benefit for doing so (or very minimal at best), but what you need to do is to redirect the old URL to the new one (if you haven't already) as this will show Google that there is a new page in place. Otherwise you are just starting with a new page. Don't change it back, but don't do this to other pages, unless you are making them friendly URL's. -Andy

		Should I optimize the login page? Will it affect the website SEO ranking?
 I'm trying to resolve the site crawl issues that we have on our website. One of the links that has different issue types together is our login page. Currently we have two login pages that have the same content but different sub domains. **However I'm wondering if optimizing SEO on our login pages affects our website SEO ranking and if it's something better to do or not. ** To point out the details of the issues, the issue types that the logins pages have are "duplicate title", "duplicate content", "missing H1", "missing description", "thin content", "missing canonical tag" I'd appreciate your help, thank you!

		Should I apply Canonical Links from my Landing Pages to Core Website Pages?
 I am working on an SEO project for the website: https://wave.com.au/ There are some core website pages, which we want to target for organic traffic, like this one: https://wave.com.au/doctors/medical-specialties/anaesthetist-jobs/ Then we have basically have another version that is set up as a landing page and used for CPC campaigns. https://wave.com.au/anaesthetists/ Essentially, my question is should I apply canonical links from the landing page versions to the core website pages (especially if I know they are only utilising them for CPC campaigns) so as to push link equity/juice across?

		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 Intermediate & Advanced SEO | | NickG-1230

		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! Intermediate & Advanced SEO | | TheDude0

		SEO impact difference between a URL Rewrite and 301 redirect
 Hi guys and girls! Just putting a new site live, we changed the URL from one thing to another and I created a 301 file redirecting the urls like for like. The developer installing it has created a different file with columns like: RewriteRule ^page/ http://www.site/page [R=301,L] RewriteRule ^/page/ http://www.site/page [R=301,L] What's the difference? The page redirects but is there a difference between the 301 redirect and this URL rewrite in terms of SEO and link value? Intermediate & Advanced SEO | | shloy23-2945840

		Is it a problem to use a 301 redirect to a 404 error page, instead of serving directly a 404 page?
 We are building URLs dynamically with apache rewrite. Intermediate & Advanced SEO | | lcourse
 When we detect that an URL is matching some valid patterns, we serve a script which then may detect that the combination of parameters in the URL does not exist. If this happens we produce a 301 redirect to another URL which serves a 404 error page, So my doubt is the following: Do I have to worry about not serving directly an 404, but redirecting (301) to a 404 page? Will this lead to the erroneous original URL staying longer in the google index than if I would serve directly a 404? Some context. It is a site with about 200.000 web pages and we have currently 90.000 404 errors reported in webmaster tools (even though only 600 detected last month).0

		Different Header on Home Page vs Sub pages
 Hello, I am an SEO/PPC manager for a company that does a medical detox. You can see the site in question here: http://opiates.com. My question is, I've never heard of it specifically being a problem to have a different header on the home page of the site than on the subpages, but I rarely see it either. Most sites, if i'm not mistaken, use a consistent header across most of the site. However, a person i'm working for now said that she has had other SEO's look at the site (above) and they always say that it is a big SEO problem to have a different header on the homepage than on the subpages. Any thoughts on this subject? I've never heard of this before. Thanks, Jesse Intermediate & Advanced SEO | | Waismann0

		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?

 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
