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/?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

Added to note - you can also use GDC to inform Google which URL parameters should be ignored when indexing - can be a quick shortcut initially, but you'll definitely want to get rel-canonical properly implemented for Google as well as all the other search engines.

This issue is resolved by adding a single self-referential rel-canonical tag to the header of each page of the site, Catherine. Once you've done that, the URLs that contain the parameters will automatically contain the canonical to the primary URL (because the pages' code are actually the same - it's just the URL itself that is changing. By which I mean - there aren't separate pages for each of the currencies. They're are all the same page code, with just the parameter added to the URL and prices dynamically changed.)
This does mean that the search engines would index the page with the default prices, which appears to be Euros.
For example, if your home page had a self-referential canonical tag, it's canonical tag would be
<link rel="<a class="attribute-value">canonical</a>" href="<a class="attribute-value">http://www.marcb.com</a>" />
While this may seem redundant, it also means that this URL https://www.marcb.com/?setCurrencyId=2 would also contain the above canonical tag, since the page is actually built from the same code. So it's canonical would point to the correct URL automatically, without having to do anything specific for all those variations. This is a core function of how CMSs (Content Management Systems) templates work. This time it works in your favour.
You definitely don't want to no-index those parameter-based variations even if you could. Once you get the canonicals properly implemented, you want the search crawlers to keep crawling those pages URLs so they can discover the corrected canonicals and understand that they are intentional dupes of the core page. They'll eventually drop the parameter-based URLs out of the index, which you can monitor in your Google Search Console, for example. There's a major benefit to the site if the search crawlers aren't wasting their time on duplicate/useless pages, as well as reducing potential issues with Panda/Quality algorithms, so well worth getting this corrected right away.
Hope all that makes sense?
Paul

How do I treat URLs with bookmarks when migrating a site?
I'm migrating an old website into a new one, and have several pages that have bookmarks on them. Do I need to redirect those? or how should they be treated? For example, both https://www.tnscanada.ca/our-expertise.html and https://www.tnscanada.ca/our-expertise.html#auto resolve .

Shopify Site with Multiple Domains?
Hey there! My client has a website on Shopify. I don't even know how to open this can of worms, but let me try. The site URL is: https://mobilityequipmentforless.com/ However, there is another (older?) URL that gets updated as the main site gets updated and shows the exact same content. It's a straight duplicate, but is it's own URL and doesn't redirect to the main site. https://www.powerchairrecyclers.com/ And this isn't the SITE.Shopify back-end site name that was used for set up initially. I just have no idea what's going on here. Not sure if it's a serious error that needs to be fixed, or if it's something weird with how Shopify work. Any insight would be immensely helpful. Thanks!

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 -
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!

Does a non-canonical URL pass link juice?
Our site received a great link from URL A, which was syndicated to URL B. But URL B is canonicalized to URL A. Does the link on URL B pass juice to my site? (See image below for a visual representation of my question) zgbzqBy

Multiple 301 redirects for a HTTPS URL. Good or bad?
I'm working on an ecommerce website that has a few snags and issues with it's coding. They're using https, and when you access the website through domain.com, theres a 301 redirect to http://www.domain.com and then this, in turn, redirected to https://www.domain.com. Would this have a deterimental effect or is that considered the best way to do it. Have the website redirect to http and then all http access is redirected to the https URL? Thanks

URL Structure for Directory Site
We have a directory that we're building and we're not sure if we should try to make each page an extension of the root domain or utilize sub-directories as users narrow down their selection. What is the best practice here for maximizing your SERP authority? Choice #1 - Hyphenated Architecture (no sub-folders): State Page /state/ City Page /city-state/ Business Page /business-city-state/
Intermediate & Advanced SEO | | knowyourbank
4) Location Page /locationname-city-state/ or.... Choice #2 - Using sub-folders on drill down: State Page /state/ City Page /state/city Business Page /state/city/business/
4) Location Page /locationname-city-state/ Again, just to clarify, I need help in determining what the best methodology is for achieving the greatest SEO benefits. Just by looking it would seem that choice #1 would work better because the URL's are very clear and SEF. But, at the same time it may be less intuitive for search. I'm not sure. What do you think?0 -
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
