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?

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,

Google cache is showing my UK homepage site instead of the US homepage and ranking the UK site in US
Hi There, When I check the cache of the US website (www.us.allsaints.com) Google returns the UK website. This is also reflected in the US Google Search Results when the UK site ranks for our brand name instead of the US site. The homepage has hreflang tags only on the homepage and the domains have been pointed correctly to the right territories via Google Webmaster Console.This has happened before in 26th July 2015 and was wondering if any had any idea why this is happening or if any one has experienced the same issueFDGjldR

How do you 301 redirect URLs with a hashbang (#!) format? We just lost a ton of pagerank because we thought javascript redirect was the only way! But other sites have been able to do this – examples and details inside
Hi Moz, Here's more info on our problem, and thanks for reading! We’re trying to Create 301 redirects for 44 pages on site.com. We’re having trouble 301 redirecting these pages, possibly because they are AJAX and have hashbangs in the URLs. These are locations pages. The old locations URLs are in the following format: www.site.com/locations/#!new-york and the new URLs that we want to redirect to are in this format: www.site.com/locations/new-york We have not been able to create these redirects using Yoast WordPress SEO plugin v.1.5.3.2. The CMS is WordPress version 3.9.1 The reason we want to 301 redirect these pages is because we have created new pages to replace them, and we want to pass pagerank from the old pages to the new. A 301 redirect is the ideal way to pass pagerank. Examples of pages that are able to 301 redirect hashbang URLs include http://www.sherrilltree.com/Saddles#!Saddles and https://twitter.com/#!RobOusbey.

How can I get a list of every url of a site in Google's index?
I work on a site that has almost 20,000 urls in its site map. Google WMT claims 28,000 indexed and a search on Google shows 33,000. I'd like to find what the difference is. Is there a way to get an excel sheet with every url Google has indexed for a site? Thanks... Mike

Do UTM URL parameters hurt SEO backlink value?
Does www.example.com and www.example.com/?utm_source=Google&utm_medium=Press+Release&utm_campaign=Google have the same SEO backlink value? I would assume that Google knows the difference.

URL Length or Exact Breadcrumb Navigation URL? What's More Important
Basically my question is as follows, what's better: www.romancingdiamonds.com/gemstone-rings/amethyst-rings/purple-amethyst-ring-14k-white-gold (this would fully match the breadcrumbs). or www.romancingdiamonds.com/amethyst-rings/purple-amethyst-ring-14k-white-gold (cutting out the first level folder to keep the url shorter and the important keywords are closer to the root domain). In this question http://www.seomoz.org/qa/discuss/37982/url-length-vs-url-keywords I was consulted to drop a folder in my url because it may be to long. That's why I'm hesitant to keep the bradcrumb structure the same. To the best of your knowldege do you think it's best to drop a folder in the URL to keep it shorter and sweeter, or to have a longer URL and have it match the breadcrumb structure? Please advise, Shawn
