Duplicate Content Issues on Product Pages
-
Hi guys
Just keen to gauge your opinion on a quandary that has been bugging me for a while now.
I work on an ecommerce website that sells around 20,000 products.
A lot of the product SKUs are exactly the same in terms of how they work and what they offer the customer. Often it is 1 variable that changes. For example, the product may be available in 200 different sizes and 2 colours (therefore 400 SKUs available to purchase).
Theese SKUs have been uploaded to the website as individual entires so that the customer can purchase them, with the only difference between the listings likely to be key signifiers such as colour, size, price, part number etc.
Moz has flagged these pages up as duplicate content.
Now I have worked on websites long enough now to know that duplicate content is never good from an SEO perspective, but I am struggling to work out an effective way in which I can display such a large number of almost identical products without falling foul of the duplicate content issue.
If you wouldnt mind sharing any ideas or approaches that have been taken by you guys that would be great!
-
The canonical should pass link equity similar to a 301 redirect.
-
Thanks Mike. It certainly sounds like moving all SKUs onto 1 page is preferable. I suspect that I may need to spend a bit of dosh getting the website's on-page structure amended if going down this approach.
With regards to point 1, I assume the pages will still be crawled but any link equity would be passed to the canonicalised version of the page?
-
I agree with Everett from a standpoint of User Experience. It could potentially be better for users if they appeared on a product page where they could then choose color, size, etc. variables for their product instead of having to click through multiple pages to find the right one or scroll through a huge list of variations.
The reduction in pages should also help consolidate link equity and keep pages from cannibalizing each other in the SERPs.
As for Takeshi's suggestion on Canonicals, I'm a fan of the rel=canonical tag but the potential problem with using them in this instance is twofold. 1) As Takeshi mentioned: "as far as Google is concerned you only have 1 page with the content on it" and 2) Canonicals are suggestions not directives so the search engines may choose not to recognize it if not used properly.
-
As I said, that would be a good second choice, but I'd go with the first option (putting all product variants like size/color on the same page and allowing the user to select which one/s they want to purchase) because the other options still leave a potentially huge amount of product URLs out there for Google to crawl.
Google has to crawl them to see the rel canonical tag. You may only have a certain amount of crawl budget. If you can cut down the amount of URLs on your site that Google has to crawl by as much as half simply by allowing users to select a variant color or size on a product page I think that is best for SEO, as well as for user experience.
-
Thanks for the advice guys.
What do you think of Takeshi's advice below regarding adding canonical link to product page that points to a product category page
I.e. we have 20 of the same jumpers of different sizes, colours. A canonical tag is added to the product page that points to a parent page for the jumper, rather than the specific product page.
-
Thanks Takeshi - this approach sounds like something I can implement sooner rather than later.
Have you had success using it?
-
Thanks Mike - this certainly makes sense.
My product pages do not currently change the URL parameters depending ont he product sku the visitor changes , but the approach you've taken sounds perfect for your setup

Similar to what BJS1976 and Takeshi stated, the way we handled the bulk of duplicate content issues from a similar circumstance for our ecommerce site was handling the different varieties of the same product through parameters and then canonicalizing the parameters to the version of the URL sans parameter.
For example, due to database reasons /product1.php?color=42 and /product1.php?color=30 are the same product but one is red and one is blue, the pages are exactly the same & have radials/buttons/dropdowns to choose any available color, /product1.php would default to one specific variation we chose (usually the best selling color) and then /product1.php?color=42 and /product1.php?color=30 had a rel=canonical tag added pointing at /product1.php
For any remaining products flagged as duplicates that couldn't be fixed that way, we set those aside to have myself and another copywriter work on creating further content that would set them apart enough as to not be duplicates.
-
BJS1976 makes some good suggestions.
Another option is to create a category type page that lists all the product variations on it, then canonical each of the individual products to the category page. That way, you still have multiple product pages, but as far as Google is concerned you only have 1 page with the content on it.

Hi there,
I'm also working on an ecom site using Magento - in short, there are a couple of ways that come to mind in how to deal with this:
-
Create grouped or configurable products that bring these simple products into 1 single product - customer then chooses size and colour for example.
-
Rewrite a lot of unique content in the product descriptions for each variation.
In my experience, sales convert better on option 1, plus my gut tells me they are favoured by Google.
Good luck!

Customer Reviews on Product Page / Pagination / Crawl 3 review pages only
Hi experts, I present customer feedback, reviews basically, on my website for the products that are sold. And with this comes the ability to read reviews and obviously with pagination to display the available reviews. Now I want users to be able to flick through and read the reviews to help them satisfy whatever curiosity they have. My only thinking is that the page that contains the reviews, with each click of the pagination will present roughly the same content. The only thing that changes is the title tags which will contain the number in the H1 to display the page number. I'm thinking this could be duplication but i have yet to be notified by Google in my Search console... Should i block crawlers from crawling beyond page 3 of reviews? Thanks

Duplicate content and 404 errors
I apologize in advance, but I am an SEO novice and my understanding of code is very limited. Moz has issued a lot (several hundred) of duplicate content and 404 error flags on the ecommerce site my company takes care of. For the duplicate content, some of the pages it says are duplicates don't even seem similar to me. additionally, a lot of them are static pages we embed images of size charts that we use as popups on item pages. it says these issues are high priority but how bad is this? Is this just an issue because if a page has similar content the engine spider won't know which one to index? also, what is the best way to handle these urls bringing back 404 errors? I should probably have a developer look at these issues but I wanted to ask the extremely knowledgeable Moz community before I do 🙂

Car Dealership website - Duplicate Page Content Issues
Hi, I am currently working on a large car dealership website. I have just had a Moz crawl through and its flagging a lot of duplicate page content issues, these are mostly for used car pages. How can I get round this as the site stocks many of the same car, model, colour, age, millage etc. Only unique thing about them is the reg plate. How do I get past this duplicate issue if all the info is relatively the same? Anyone experienced this issue when working on a car dealership website? Thank you.

Handling of Duplicate Content
I just recently signed and joined the moz.com system. During the initial report for our web site it shows we have lots of duplicate content. The web site is real estate based and we are loading IDX listings from other brokerages into our site. If though these listings look alike, they are not. Each has their own photos, description and addresses. So why are they appear as duplicates – I would assume that they are all too closely related. Lots for Sale primarily – and it looks like lazy agents have 4 or 5 lots and input the description the same. Unfortunately for us, part of the IDX agreement is that you cannot pick and choose which listings to load and you cannot change the content. You are either all in or you cannot use the system. How should one manage duplicate content like this? Or should we ignore it? Out of 1500+ listings on our web site it shows 40 of them are duplicates.

Duplicate content on Product pages for different product variations.
I have multiple colors of the same product, but as a result I'm getting duplicate content warnings. I want to keep these all different products with their own pages, so that the color can be easily identified by browsing the category page. Any suggestions?

"nofollow pages" or "duplicate content"?
We have a huge site with lots of geographical-pages in this structure: domain.com/country/resort/hotel domain.com/country/resort/hotel/facts domain.com/country/resort/hotel/images domain.com/country/resort/hotel/excursions domain.com/country/resort/hotel/maps domain.com/country/resort/hotel/car-rental Problem is that the text on ie. /excursions is often exactly the same on .../alcudia/hotel-sea-club/excursion and .../alcudia/hotel-beach-club/excursion The two hotels offer the same excursions, and the intro text on the pages are the exact same throughout the entire site. This is also a problem on the /images and /car-rental pages. I think in most cases the only difference on these pages is the Title, description and H1. These pages do not attract a lot of visits through search-engines. But to avoid them being flagged as duplicate content (we have more than 4000 of these pages - /excursions, /maps, /car-rental, /images), do i add a nofollow-tag to these, do i block them in robots.txt or should i just leave them and live with them being flagged as duplicate content? Im waiting for our web-team to add a function to insert a geographical-name in the text, so i could add ie #HOTELNAME# in the text and thereby avoiding the duplicate text. Right now we have intros like: When you visit the hotel ... instead of: When you visit Alcudia Sea Club But untill the web-team has fixed these GEO-tags, what should i do? What would you do and why?

Duplicate Content issue
I have been asked to review an old website to an identify opportunities for increasing search engine traffic. Whilst reviewing the site I came across a strange loop. On each page there is a link to printer friendly version: http://www.websitename.co.uk/index.php?pageid=7&printfriendly=yes That page also has a link to a printer friendly version http://www.websitename.co.uk/index.php?pageid=7&printfriendly=yes&printfriendly=yes and so on and so on....... Some of these pages are being included in Google's index. I appreciate that this can't be a good thing, however, I am not 100% sure as to the extent to which it is a bad thing and the priority that should be given to getting it sorted. Just wandering what views people have on the issues this may cause?
