Ecommerce store on subdomain - danger of keyword cannibalization?
-
Hi all,
Scenario: Ecommerce website selling a food product has their store on a subdomain (store.website.com). A GOOD chunk of the URLs - primarily parameters - are blocked in Robots.txt. When I search for the products, the main domain ranks almost exclusively, while the store only ranks on deeper SERPs (several pages deep).
In the end, only one variation of the product is listed on the main domain (ex: Original Flavor 1oz 24 count), while the store itself obviously has all of them (most of which are blocked by Robots.txt).
Can anyone shed a little bit of insight into best practices here? The platform for the store is Shopify if that helps. My suggestion at this point is to recommend they all crawling in the subdomain Robots.txt and canonicalize the parameter pages.
As for keywords, my main concern is cannibalization, or rather forcing visitors to take extra steps to get to the store on the subdomain because hardly any of the subdomain pages rank. In a perfect world, they'd have everything on their main domain and no silly subdomain.
Thanks!

I posted a bit of a Reddit rant here under my personal SEO alias of "studiumcirclus":
(click "View Entire Discussion")
Mainly these things vex me about the platform:
"In basic terms, Shopify is limited by its vision. They want to make sites easy to design for the average-joe, which means they have to spend most of their platform dev time on the back-end of the system and not the front-end of the sites which it produces
_ If they're always bogged down making extra tick-boxes to change things in the back-end, how can they be keeping up with cutting edge SEO? With WordPress you have a much larger dev community making add-ons, many of them completely free and still very effective. Because everyone is on WP, when new Google features, directives or initiatives come out they are quickly embraced (putting all sites on WP one step ahead)_
_ With smaller dev communities, platforms like Shopify or Magento lag behind. Why do people always expect that 'average' will rank 'well'? Ahead of the curve ranks well, average ranks averagely_
_ Also Shopify has some nasty Page-Speed issues which they won't acknowledge and they just argue about instead of fixing things. It's just not good for SEO_"
Other "Shopify is bad" evidence:
https://moz.com/community/q/main-menu-duplication#reply_391855 - just contains some of my thoughts on why Shopify isn't that good
https://moz.com/community/q/site-crawl-status-code-430 - a relatively recent problem someone had with their Shopify site, scroll down to see my reply
https://moz.com/community/q/duplicate-content-in-shopify-subsequent-pages-in-collections - someone else having tech issues with their Shopify site. While my answer was probably right, they probably couldn't implement the fixes

This was incredibly helpful. Right now their funnel starts on the store (adding product to cart), but there's definitely a benefit to it starting on the main domain to better track how the channels perform and overall user behavior.

In summary - firstly echo effectdigital on Shopify. It is an interesting platform sold very well by Shopify zealots - but we have had to bend too many times to Shopify platform limitations to believe it is the right answer for most. It is awesome if your a bikini start-up with no CRM or ERP - however the moment it comes to a decent integration - it often gets ugly quickly.
On to your query - the shortened version to the answer is no-one knows. Why? because the algorithm treats subdomains differently for different sites. https://moz.com/blog/interview-searchlove There is a good piece on subdomains v subfolders in this WBF. In summary a good discussion on subdomains.
The click through to the subdomain should be a normal step, ie so assuming on the subdomain your landing on the relevant contextual page within the funnel to transact. That is normal for some back ends. You are correct ideally in my view all on the root domain.
Overall if the subdomain pages are critical and you want to rank, then need to treat subdomain for SEO as a separate site. However, if the subdomain is just the end part of the sales funnel.. then may not need to rank..
Hope that is helpful.
Regards

One reason we got out of shopify. Gets complicated quickly. There was a brilliant WBF on subdomains about 2 months ago - by the british dude from distilled who pops up from time to time. Will try and find it if get time, but would check that out as a starting point.

Yeah, I'm trying to figure out the best way to present to them all the pertinent information regarding how terrible Shopify is. The way they use Collections then block any sort of parameters in their unalterable Robots.txt file is insane.
-
That sounds like a hell of a mess. Instead of tying your name to one proposed implementation and saying "yes, this IS the way" - I'd get the complexity of the issue across to the client / boss
I'd then present your idea and say "I want to test this, but if results suffer we will need to revert the changes". I think that with such a complex architectural nightmare (on a HORRIBLE platform like Shopify, which is just awful for SEO) - it would be extremely foolish to charge off into the night without making the risks clear
The best practice is really to not have built such a terrible site to begin with. In making things better, there may be growing pains. There may be NO options which would result in 100% growth and 0% losses
My recommendation would be to continue blocking Google's access to the original, default product variations (as those are already happily ranking on the main site. Don't fix what ain't broken). I might allow Google to crawl the sub-variations which are inaccessible from the main site. I might alter the main site's UX to include links to the sub-variants on the 'shop.' subdomain
In the end though, it's a very tangled web they have spun

Proper Title Tags for ecommerce
In terms of E-commerce title tags. We are a manufacturer of our own clothing products. We are new to the SEO landscape so if this question is an obvious answer, then i apologize for wasting any one times in advance. We Manufacture our own clothing. Each item has a name. The names are American womens names such as amanda or lori or jenniffer etc. When we create the title tag for them should we include the name of the item itself at the beginning or end. For example should it be Item Name - Keyword - Keyword - Brand Name(aka manufacturer) or Keyword - Keyword - Item Name - Brand Name (aka manufacturer) The reason we ask this is because we think it would be a waste to rank for actual American names such as Jennifer and Jessica. All that we have read on Moz suggests that it seems to be better to have pertinent keywords in the beginning of the title as opposed to the end. In terms of our brand name we already rank number 1 for every combination of our brand. So we would like to start picking up traffic for the different product types we sell and there respective synonyms. Not sure if i am making any sense. Sorry in advance, and any help is very very much appreciated.

Archiving a festival website - subdomain or directory?
Hi guys I look after a festival website whose program changes year in and year out. There are a handful of mainstay events in the festival which remain each year, but there are a bunch of other events which change each year around the mainstay programming.This often results in us redoing the website each year (a frustrating experience indeed!) We don't archive our past festivals online, but I'd like to start doing so for a number of reasons 1. These past festivals have historical value - they happened, and they contribute to telling the story of the festival over the years. They can also be used as useful windows into the upcoming festival. 2. The old events (while no longer running) often get many social shares, high quality links and in some instances still drive traffic. We try out best to 301 redirect these high value pages to the new festival website, but it's not always possible to find a similar alternative (so these redirects often go to the homepage) Anyway, I've noticed some festivals archive their content into a subdirectory - i.e. www.event.com/2012 However, I'm thinking it would actually be easier for my team to archive via a subdomain like 2012.event.com - and always use the www.event.com URL for the current year's event. I'm thinking universally redirecting the content would be easier, as would cloning the site / database etc. My question is - is one approach (i.e. directory vs. subdomain) better than the other? Do I need to be mindful of using a subdomain for archival purposes? Hope this all makes sense. Many thanks!

Follow or nofollow to subdomain
Hi, I run a hotel booking site and the booking engine is setup on a subdomain.

The subdomain is disabled from being indexed in robots.txt Should the links from the main domain have a nofollow to the subdomain? What are you thoughts? Thanks!0 -
Getting a Sitemap for a Subdomain into Webmaster Tools
We have a subdomain that is a Wordpress blog, and it takes days, sometimes weeks for most posts to be indexed. We are using the Yoast plugin for SEO, which creates the sitemap.xml file. The problem is that the sitemap.xml file is located at blog.gallerydirect.com/sitemap.xml, and Webmaster Tools will only allow the insertion of the sitemap as a directory under the gallerydirect.com account. Right now, we have the sitemap listed in the robots.txt file, but I really don't know if Google is finding and parsing the sitemap. As far as I can tell, I have three options, and I'd like to get thoughts on which of the three options is the best choice (that is, unless there's an option I haven't thought of): 1. Create a separate Webmaster Tools account for the blog 2. Copy the blog's sitemap.xml file from blog.gallerydirect.com/sitemap.xml to the main web server and list it as something like gallerydirect.com/blogsitemap.xml, then notify Webmaster Tools of the new sitemap on the galllerydirect.com account 3. Do an .htaccess redirect on the blog server, such as RewriteRule ^sitemap.xml http://gallerydirect.com/blogsitemap_index.xml Then notify Webmaster Tools of the new blog sitemap in the gallerydirect.com account. Suggestions on what would be the best approach to be sure that Google is finding and indexing the blog ASAP?

Use of subdomains, subdirectories or both?
Hello, i would like your advice on a dilemma i am facing. I am working a new project that is going to release soon, thats a network of users with personal profiles seperated in categories for example lets say the categories are colors. So let say i am a member and i belong in red color categorie and i got a page where i update my personal information/cv/resume as well as a personal blog thats on that page. So the main site is giving the option to user to search for members by the criteria of color. My first idea is that all users should own a subdomain (and this is how its developed so far) thats easy to use and since the domain name is really small (just 3 letters) i believe subdomain worth since personal site will be easy to remember. My dilemma is should all users own a subdomain, a subdirectory or both and if both witch one should be the canonical? Since it said that search engines treat subdomains as different stand-alone sites, whats best for the main site? to show multiple search results with profiles in subdomains or subdirectories? What if i use both? meaning in search results i use search directory url for each profile while same time each profile owns a subdomains as well? and if so which one should be the canonical? Thanks in advance, C

Migrating online store to subdomain using shopify and effects on seo and energy down the road for seo
I'm looking for some clarity... Looking at using Shopify for an existing online store that we have to migrate. Setting up the store with shopify means we will be using a subdomain such as shop.mywebsite.com instead of mywebsite.com/shop. The following are points to consider when responding The client currently has an online store, however it's a proprietary shopping store and CMS that has since gone defunct and they need to migrate to an alternative in order to survive online against new CMS systems that allow the site and its content to be better optimized. There is a lot of existing SEO done on the current site that we don't want to loose PR on. There is roughly 2000 products Client has a fixed budget, dealing with checkout issues, custom work and various other "bugs" seems to be easier controlled with Shopify...thus budget can be used more on content/strategy and migration We want to run the main site in Wordpress and are wanting to use Shopify since it supports a gateway, has great features and seems like it would allow us to get more bang for the buck and can focus more on the main site and content strategy and drive traffic to the subdomain store if needed Or main concern is the effort of migrating 2000+ products to shopify and the traffic and PR it gives the current site will have a negative effect on the main domain itself. Should we really be considering this path? The domain is diveidc.com One main benefit to the subdomain is the ability to clearly segment products from the service portion of the site in the analytics and focus 2 clear strategies and track it in a very defined manner. We're really on the fence with this...any thoughts are welcome.
