E-commerce site, one product multiple categories best practice
-
Hi there,
We have an e-commerce shopping site with over 8000 products and over 100 categories.
Some sub categories belong to multiple categories - for example, A Christmas trees can be under "Gardening > Plants > Trees" and under "Gifts > Holidays > Christmas > Trees"
The product itself (example: Scandinavian Xmas Tree) can naturally belong to both these categories as well.
Naturally these two (or more) categories have different breadcrumbs, different navigation bars, etc. From an SEO point of view, to avoid duplicate content issues, I see the following options:
- Use the same URL and change the content of the page (breadcrumbs and menus) based on the referral path. Kind of cloaking.
- Use the same URL and display only one "main" version of breadcrumbs and menus. Possibly add the other "not main" categories as links to the category / product page.
- Use a different URL based on where we came from and do nothing (will create essentially the same content on different urls except breadcrumbs and menus - there's a possibiliy to change the category text and page title as well)
- Use a different URL based on where we came from with different menus and breadcrumbs and use rel=canonical that points to the "main" category / product pages
This is a very interesting issue and I would love to hear what you guys think as we are finalizing plans for a new website and would like to get the most out of it.
Thank you all!

Hi,
This topic is quite old, but is still relevant.
I understand that the solution mentioned above is the most thorough one.
But is there something wrong with just using canonicals? In a webshop that we are managing, there are just a couple of subcategories that belong to different categories. An example:
Only these two URL's will generate duplicate content, since the categories above 'Company law' ('Economic law' and 'Companies') clearly have different content. Can't you just pick one version as the canonical one? Since we have just a couple of these categories, this is an easier solution.
Thanks for your feedback guys!

Thought I'd answer my own question!! (with the help of Dr Pete, who answered this question in private Q&A)
"The multiple path issue is tough - you can't really have a path visitors can follow and then hide that from Google (or, at least, it's not a good idea). You could NOINDEX certain paths, but that's a complex consideration (it has pros and cons and depends a lot on your goals and site architecture).
If you generate the breadcrumb path via user activity and store it in a session/cookie, that's generally ok. Google's crawlers, as well as any visitor who came to the site via search, would see a default breadcrumb, but visitors would see a breadcrumb based on their own activity. That's fine, since the default is the same for humans as for spiders."
That seems to be a fairly conclusive answer IMO.

Hi Arik,
I'd really like an answer to this aswell, as there seems to be no clear answer online.
My understanding is that a breadcrumb should specify a canonical crawl path (not based on referral path), so option 1 is out
option 2 seems suboptimal and not something I can recall seeing implemented on other sites
options 3 and 4: I don't want multiple URLs and to use rel=canonical as I already have one definitive URL.
This seems like it must be a fairly regular problem people have, but cant see a good solution online anywhere
Help anyone?

Dear All,
I repeat about Option 1: Use the same URL and change the content of the page (breadcrumbs and menus) based on the referral path. Kind of cloaking.
Changing content based on the referral path means that the same url will have different content at times. Which means that the search engine will probably find a different content on the page than some other views of the page. As far as I know, this is cloaking - please correct me if I'm wrong.
Option 4 will not necessarily achieve the desired effect as the search engine might decide to ignore the tag. i checked a few examples that this is actually what happens when other e-commerce stores use canonical - you find both URLs in the serps. So I doubt this is the perfect solution...
I'm still not convinced that I have a definitive answer for this. Anyone?
Thanks!

Option 1 is not cloaking - it is displaying content dynamically. Cloaking would be if you showed one page to viewers and a different version to Googlebot.
I would say it depends on how different pages are. If all that changes in the breadcrumbs, they I would say you're fine with options 1, 2, or 4.
If the pages are significantly different, such as different category names, page titles, descriptive text, etc. I would go with option 4.
-
Thanks Adam.
I very much respect your opinion and even agree that from a user's point of view option 1 is the best.
I wonder though - it's this considered as cloaking?

From:
http://support.google.com/webmasters/bin/answer.py?hl=en&answer=66355Cloaking refers to the practice of presenting different content or URLs to human users and search engines. Cloaking is considered a violation of Google’s Webmaster Guidelines because it provides our users with different results than they expected.
Some examples of cloaking include:
[...]
Inserting text or keywords into a page only when the User-agent requesting the page is a search engine, not a human visitor|
|
This becomes more complicated, as the path the user chose to get to the specific subcategory or product page reflects not only on the breadcrumbs but also on the category's navigation menu and possibly the descriptive text of the category.
What's your take on this?
-
Options 1, 2, or 4 should be fine. Option 3 is not recommended.

How does product category description affect SEO?
Hi - we are a website that sells tours. We have category pages that list the tours in that category (by city, by length of time, theme, etc). At the top of each category page, before the buttons linking to the tours, there is a category description. It is a pretty long paragraph. We are redesigning the website and think it would look nicer to show 2-3 lines of text and then have a down arrow and 'read' more so people can click and it would expand to show the full category description if they want to read it and it won't take up so much room that way. My question is - will this affect SEA at all? Or because the text is still there, just hidden, it won't do anything? Our site ranks very high in organic searches on google and we do not want to do anything that will hurt SEO. thanks.

Splitting One Site Into Two Sites Best Practices Needed
Okay, working with a large site that, for business reasons beyond organic search, wants to split an existing site in two. So, the old domain name stays and a new one is born with some of the content from the old site, along with some new content of its own. The general idea, for more than just search reasons, is that it makes both the old site and new sites more purely about their respective subject matter. The existing content on the old site that is becoming part of the new site will be 301'd to the new site's domain. So, the old site will have a lot of 301s and links to the new site. No links coming back from the new site to the old site anticipated at this time. Would like any and all insights into any potential pitfalls and best practices for this to come off as well as it can under the circumstances. For instance, should all those links from the old site to the new site be nofollowed, kind of like a non-editorial link to an affiliate or advertiser? Is there weirdness for Google in 301ing to a new domain from some, but not all, content of the old site. Would you individually submit requests to remove from index for the hundreds and hundreds of old site pages moving to the new site or just figure that the 301 will eventually take care of that? Is there substantial organic search risk of any kind to the old site, beyond the obvious of just not having those pages to produce any more? Anything else? Any ideas about how long the new site can expect to wander the wilderness of no organic search traffic? The old site has a 45 domain authority. Thanks!

What is best practice for "Sorting" URLs to prevent indexing and for best link juice ?
We are now introducing 5 links in all our category pages for different sorting options of category listings.
Intermediate & Advanced SEO | | lcourse
The site has about 100.000 pages and with this change the number of URLs may go up to over 350.000 pages.
Until now google is indexing well our site but I would like to prevent the "sorting URLS" leading to less complete crawling of our core pages, especially since we are planning further huge expansion of pages soon. Apart from blocking the paramter in the search console (which did not really work well for me in the past to prevent indexing) what do you suggest to minimize indexing of these URLs also taking into consideration link juice optimization? On a technical level the sorting is implemented in a way that the whole page is reloaded, for which may be better options as well.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!

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 -

ECommerce product listed in multiple places, best SEO practice?
We have an eCommerce site we have built for a customer and the products are allowed to appear in more than one product category within the web site. Now I know this is a bad idea from a duplicate content point of view, But we are going to allow the customer to select which out of the multiple categories the product appears in will be the default category. This will mean we will have a way of defining what the default url is for a product. So am I correct in thinking all the other urls where the product appears we should add a rel canonical to these pages pointing to the default url to stop duplicate content? Is this the best way?

Multiple stores & domains vs. One unified store (SEO pros / cons for E-Commerce)
Our company runs a number of individual online shops, specialised in particular products but all in the same genre of goods overall, with a specific and relevant domain name for each shop. At the moment the sites are separate, and not interlinked, i.e. Completely separate brands. An analogy could be something like clothing accessories (we are not in the clothing business): scarves.com, and silkties.com (our field is more niche than this) We are about to launch a related site, (e.g. handbags.com), in the same field again but without precisely overlapping products. We will produce this site on a newer, more flexible e-commerce platform, so now is a good time to consider whether we want to place all our sites together with one e-commerce system on the backend. Essentially, we need to know what the pros and cons would be of the various options facing us and how the SEO ranking is affected by the three possibilities. Option 1: continue with separate sites each with its own domains. Option 2: have multiple sites, each on their own domain, but on the same ecommerce system and visible linked together for the customer (with unified checkout) – on the top of each site could be a menu bar linking to each site: [Scarves.com] – [SilkTies.com] – [Handbags.com] The main question here is whether the multiple domains are mutually beneficial, particularly considerding how close to target keywords the individual domains are. If mutually benefitial, how does it compare to option 3: Option 3: Having recently acquired a domain name (e.g. accessories.com) which would cover the whole category together, we are presented with a third option: making one site selling all of these products in different categories. Our main concern here would be losing the ability to specifically target marketing, and losing the benefit of the domains with the key words in for what people are more likely to be searching for (e.g. 'silk tie') rather than 'accessories.' Is it worth taking the hit on losing these specific targeted domain names for the advantage of increased combined inbound links?
