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

301 Redirects for Multiple Language Sites in htaccess File
Hi everyone, I have a site on a subdomain that has multiple languages set up at the domain level: https://mysite.site.com, https://mysite.site.fr , https://mysite.site.es , https://mysite.site.de , etc. We are migrating to a new subdomain and I am trying to create 301 redirects within the htaccess file, but I am a bit lost on how to do this as it seems you have to go from a relative url to an absolute - which would be fine if I was only doing this for the english site, but I'm not. It doesn't seem like I can go from absolute url to an absolute url - but I could be wrong. I am new to editing the htaccess file - so I could definitely use some advice here. Thanks.

My url disappeared from Google but Search Console shows indexed. This url has been indexed for more than a year. Please help!
Super weird problem that I can't solve for last 5 hours. One of my urls: https://www.dcacar.com/lax-car-service.html Has been indexed for more than a year and also has an AMP version, few hours ago I realized that it had disappeared from serps. We were ranking on page 1 for several key terms. When I perform a search "site:dcacar.com " the url is no where to be found on all 5 pages. But when I check my Google Console it shows as indexed I requested to index again but nothing changed. All other 50 or so urls are not effected at all, this is the only url that has gone missing can someone solve this mystery for me please. Thanks a lot in advance.

Link juice through URL parameters
Hi guys, hope you had a fantastic bank holiday weekend. Quick question re URL parameters, I understand that links which pass through an affiliate URL parameter aren't taken into consideration when passing link juice through one site to another. However, when a link contains a tracking URL parameter (let's say gclid=), does link juice get passed through? We have a number of external links pointing to our main site, however, they are linking directly to a unique tracking parameter. I'm just curious to know about this. Thanks, Brett

Google Ignoring Canonical Tag for Hundreds of Sites
Bazaar Voice provides a pretty easy-to-use product review solution for websites (especially sites on Magento): https://www.magentocommerce.com/magento-connect/bazaarvoice-conversations-1.html If your product has over a certain number of reviews/questions, the plugin cuts off the number of reviews/questions that appear on the page. To see the reviews/questions that are cut off, you have to click the plugin's next or back function. The next/back buttons' URLs have a parameter of "bvstate....." I have noticed Google is indexing this "bvstate..." URL for hundreds of sites, even with the proper rel canonical tag in place. Here is an example with Microsoft: http://webcache.googleusercontent.com/search?q=cache:zcxT7MRHHREJ:www.microsoftstore.com/store/msusa/en_US/pdp/Surface-Book/productID.325716000%3Fbvstate%3Dpg:8/ct:r+&cd=2&hl=en&ct=clnk&gl=us My website is seeing hundreds of these "bvstate" urls being indexed even though we have a proper rel canonical tag in place. It seems that Google is ignoring the canonical tag. In Webmaster Console, the main source of my duplicate titles/metas in the HTML improvements section is the "bvstate" URLs. I don't necessarily want to block "bvstate" in the robots.txt as it will prohibit Google from seeing the reviews that were cutoff. Same response for prohibiting Google from crawling "bvstate" in Paramters section of Webmaster Console. Should I just keep my fingers crossed that Google honors the rel canonical tag? Home Depot is another site that has this same issue: http://webcache.googleusercontent.com/search?q=cache:k0MBLFcu2PoJ:www.homedepot.com/p/DUROCK-Next-Gen-1-2-in-x-3-ft-x-5-ft-Cement-Board-172965/202263276%23!bvstate%3Dct:r/pg:2/st:p/id:202263276+&cd=1&hl=en&ct=clnk&gl=us

Ecommerce: A product in multiple categories with a canonical to create a ‘cluster’ in one primary category Vs. a single listing at root level with dynamic breadcrumb.
OK – bear with me on this… I am working on some pretty large ecommerce websites (50,000 + products) where it is appropriate for some individual products to be placed within multiple categories / sub-categories. For example, a Red Polo T-shirt could be placed within: Men’s > T-shirts >
Intermediate & Advanced SEO | | AbsoluteDesign
Men’s > T-shirts > Red T-shirts
Men’s > T-shirts > Polo T-shirts
Men’s > Sale > T-shirts
Etc. We’re getting great organic results for our general T-shirt page (for example) by clustering creative content within its structure – Top 10 tips on wearing a t-shirt (obviously not, but you get the idea). My instinct tells me to replicate this with products too. So, of all the location mentioned above, make sure all polo shirts (no matter what colour) have a canonical set within Men’s > T-shirts > Polo T-shirts. The presumption is that this will help build the authority of the Polo T-shirts page – this obviously presumes “Polo Shirts” get more search volume than “Red T-shirts”. My presumption why this is the best option is because it is very difficult to manage, particularly with a large inventory. And, from experience, taking the time and being meticulous when it comes to SEO is the only way to achieve success. From an administration point of view, it is a lot easier to have all product URLs at the root level and develop a dynamic breadcrumb trail – so all roads can lead to that one instance of the product. There's No need for canonicals; no need for ecommerce managers to remember which primary category to assign product types to; keeping everything at root level also means there no reason to worry about redirects if product move from sub-category to sub-category etc. What do you think is the best approach? Do 1000s of canonicals and redirect look ‘messy’ to a search engine overtime? Any thoughts and insights greatly received.0 -
What is the best practice for URLs for E-commerce products in multiple categories?
Hello all! I have always worked successfully with SEO on E-commerce sites, however we are currently revamping an older site for a client and so I thought I'd turn to the community to ask what the best practices that you guys are experiencing for url structures at the moment. Obviously we do not wish to create duplicate content and so the big question is, what would you guys do for the very best structure for URLs on an E-commerce site that has products in multiple categories? Let's imagine we are selling toy cars. I have a sports car for sale, so naturally it can go in the sports cars category and it could also go in to the convertibles category too. What is the best way you have found recently that works and increases rankings, but does not create duplicate content? Thanks in advance! 🙂 Kind Regards, JDM

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

If I own a .com url and also have the same url with .net, .info, .org, will I want to point them to the .com IP address?
I have a domain, for example, mydomain.com and I purchased mydomain.net, mydomain.info, and mydomain.org. Should I point the host @ to the IP where the .com is hosted in wpengine? I am not doing anything with the .org, .info, .net domains. I simply purchased them to prevent competitors from buying the domains.
