Duplicate content on ecommerce sites
-
I just want to confirm something about duplicate content.
On an eCommerce site, if the meta-titles, meta-descriptions and product descriptions are all unique, yet a big chunk at the bottom (featuring "why buy with us" etc) is copied across all product pages, would each page be penalised, or not indexed, for duplicate content?
Does the whole page need to be a duplicate to be worried about this, or would this large chunk of text, bigger than the product description, have an effect on the page.
If this would be a problem, what are some ways around it? Because the content is quite powerful, and is relavent to all products...
Cheers,

Yes, duplicate content can harm your e-commerce sites. It can confuse search engines, making it hard for your site to rank well. Here are some simple ways to deal with it:
Use Canonical Tags: This tells search engines which version of a page is the main one.
Unique Product Descriptions: Try to write unique descriptions for each product, even if they are similar.
Noindex, Follow Tags: For pages that you don't want indexed, use these tags to prevent search engines from listing them.For a full guide on handling duplicate content, check out this blog: https://www.resultfirst.com/blog/ecommerce-seo/how-to-handle-duplicate-content-on-your-ecommerce-site/
I hope it will be helpful for you.

@Dr-Pete Thanks, exactly what I was looking for. Really thank you very much

With the caveat that this is a 7-yo thread -- I'd say that it's generally more of a filter these days (vs. a Capital-P penalty). The OEM or large resellers are almost always going to win these battles, and you'll be at a disadvantage if you duplicate their product descriptions word-for-word.
Can you still rank? Sure, but you're going to have an easier time if you can add some original value. If you aren't allowed to modify the info, is there anything you can add to it -- custom reviews (not from users, but say an editorial-style review), for example? You don't have to do it for thousands of products. You could start with ten or 25 top sellers and see how things go.

What do you suggest as a solution if you are a reseller of a product and you are using the same description as measurements, characteristics etc? Especially if your wholeseller demands not to alternate the titles and the descriptions.
-
Then you are saying that all resellers selling, for example, an X model of sports shoes will get penalised because they are using the same description? Test: take a phrase or a paragraph from the most authoritative brand and paste to google. You will have results from other resellers. They don't actually look "penalized" if you see their PA score...

I'm going to generally agree with (and thumb up) Mark, but a couple of additional comments:
(1) It really varies wildly. You can, with enough duplication, make your pages look thin enough to get filtered out. I don't think there's a fixed word-count or percentage, because it depends on the nature of the duplicate content, the non-duplicate content, the structure/code of the page, etc. Generally speaking, I would not add a long chunk of "Why Buy With Us" text - not only is it going to increase duplicate-content risks, but most people won't read it. Consider something short and punchy - maybe even an image or link that goes to a site with a full description. That way, most people will get the short message and people who are worried can get more details on a stand-alone page. You could even A/B test it - I suspect the long-form content may not be as powerful as you think.
(2) While duplicate content is not "penalized" in the traditional sense, the impact of it can approach penalty-like levels since the Panda updates.
(3) Definitely agreed with Mark that you have to watch both internal and external duplication. If you're a product reseller, for example, and you have a duplicate block in your own site AND you duplicate the manufacturer's product description, then you're at even more risk.

James- Great question.....let me provide a little guidance.....we have a bunch of ecommerce sites we help manage for SEO.I am going to lump together several of googles "focus areas" into one. They are duplicate content, shallow content and copied duplicate content. Because with an ecommerce site, all 3 of these items can be the same or interchangeable thing. Here are the major issues/things to focus on:Alot of ecommerce sites, in the past, have been able to generate substantial SEO value by listing products in variations of sizes and colors and with brief descriptions , and then create 1,000's of pages of what used to be considered unique content; (Shallow content). THOSE DAYS ARE GONE. Assuming you still have the standard information copied and pasted on every page, that you mention above, ideally you want 250 unique words of description of a product. Bare minimum you should have 100 words.....and in addition to the on-page content, you should make sure your meta descriptions are unique. Remember, Unique means relevant content that is different. With duplicate content issues, google isn't penalizing you to hurt your ranking but they will only give you SEO value for the page they think is unique...for example if you have 40 pages of the same product but small variations in color or size or sku, and little to differentiate the pages, then they will count those 40 pages as 1 page....you lose the opportunity to build 39 pages of unique content value. The last thing to be careful of is if you have product that other companies have.....(you are a distributor or supplier or wholesaler and not the manufacturer). Then the manufacturer posts standard info and a bunch of people copy it and use it. YOU WILL BE PENALIZED BY GOOGLE FOR THIS BECAUSE IT IS COPIED DUPLICATE CONTENT. Most important point to remphasis----you know you are going to have some duplicate content on a website......you know that it it likely that if you are selling different variations of the same product, that you will have alot of the same stuff.....again, make sure you have unique and different content focused on your keywords. Target at least 50% different or unique content on each page as a MINIMUM.....Hope this helps.Mark

Duplicate Content and Subdirectories
Hi there and thank you in advance for your help! I'm seeking guidance on how to structure a resources directory (white papers, webinars, etc.) while avoiding duplicate content penalties. If you go to /resources on our site, there is filter function. If you filter for webinars, the URL becomes /resources/?type=webinar We didn't want that dynamic URL to be the primary URL for webinars, so we created a new page with the URL /resources/webinar that lists all of our webinars and includes a featured webinar up top. However, the same webinar titles now appear on the /resources page and the /resources/webinar page. Will that cause duplicate content issues? P.S. Not sure if it matters, but we also changed the URLs for the individual resource pages to include the resource type. For example, one of our webinar URLs is /resources/webinar/forecasting-your-revenue Thank you!

Duplicate content in Shopify - subsequent pages in collections
Hello everyone! I hope an expert in this community can help me verify the canonical codes I'll add to our store is correct. Currently, in our Shopify store, the subsequent pages in the collections are not indexed by Google, however the canonical URL on these pages aren't pointing to the main collection page (page 1), e.g. The canonical URL of page 2, page 3 etc are used as canonical URLs instead of the first page of the collections. I have the canonical codes attached below, it would be much appreciated if an expert can urgently verify these codes are good to use and will solve the above issues? Thanks so much for your kind help in advance!! -----------------CODES BELOW--------------- <title><br /> {{ page_title }}{% if current_tags %} – tagged "{{ current_tags | join: ', ' }}"{% endif %}{% if current_page != 1 %} – Page {{ current_page }}{% endif %}{% unless page_title contains shop.name %} – {{ shop.name }}{% endunless %}<br /></title>

Same site serving multiple countries and duplicated content
Hello! Though I browse MoZ resources every day, I've decided to directly ask you a question despite the numerous questions (and answers!) about this topic as there are few specific variants each time: I've a site serving content (and products) to different countries built using subfolders (1 subfolder per country). Basically, it looks like this:
Intermediate & Advanced SEO | | GhillC
site.com/us/
site.com/gb/
site.com/fr/
site.com/it/
etc. The first problem was fairly easy to solve:
Avoid duplicated content issues across the board considering that both the ecommerce part of the site and the blog bit are being replicated for each subfolders in their own language. Correct me if I'm wrong but using our copywriters to translate the content and adding the right hreflang tags should do. But then comes the second problem: how to deal with duplicated content when it's written in the same language? E.g. /us/, /gb/, /au/ and so on.
Given the following requirements/constraints, I can't see any positive resolution to this issue:
1. Need for such structure to be maintained (it's not possible to consolidate same language within one single subfolders for example),
2. Articles from one subfolder to another can't be canonicalized as it would mess up with our internal tracking tools,
3. The amount of content being published prevents us to get bespoke content for each region of the world with the same spoken language. Given those constraints, I can't see a way to solve that out and it seems that I'm cursed to live with those duplicated content red flags right up my nose.
Am I right or can you think about anything to sort that out? Many thanks,

When is Too Many Categories Too Many on a eCommerce site?
We all know that more and more people are increasing the amount of different categories that eCommerce sites have. Say for example, you have over 3,000 different products, all categories contain unique text at the top of each, all of the categories link to each other (so loads on internal linking) and no two categories contain the exact same products. My question is this, is there ever a stage that you could create too many categories? Alternatively, do you think you should just keep creating categories based on what our customers search for?

Woocommerce SEO & Duplicate content?
Hi Moz fellows, I'm new to Woocommerce and couldn't find help on Google about certain SEO-related things. All my past projects were simple 5 pages websites + a blog, so I would just no-index categories, tags and archives to eliminate duplicate content errors. But with Woocommerce Product categories and tags, I've noticed that many e-Commerce websites with a high domain authority actually rank for certain keywords just by having their category/tags indexed. For example keyword 'hippie clothes' = etsy.com/category/hippie-clothes (fictional example) The problem is that if I have 100 products and 10 categories & tags on my site it creates THOUSANDS of duplicate content errors, but If I 'non index' categories and tags they will never rank well once my domain authority rises... Anyone has experience/comments about this? I use SEO by Yoast plugin. Your help is greatly appreciated! Thank you in advance. -Marc

International SEO - cannibalisation and duplicate content
Hello all, I look after (in house) 3 domains for one niche travel business across three TLDs: .com .com.au and co.uk and a fourth domain on a co.nz TLD which was recently removed from Googles index. Symptoms: For the past 12 months we have been experiencing canibalisation in the SERPs (namely .com.au being rendered in .com) and Panda related ranking devaluations between our .com site and com.au site. Around 12 months ago the .com TLD was hit hard (80% drop in target KWs) by Panda (probably) and we began to action the below changes. Around 6 weeks ago our .com TLD saw big overnight increases in rankings (to date a 70% averaged increase). However, almost to the same percentage we saw in the .com TLD we suffered significant drops in our .com.au rankings. Basically Google seemed to switch its attention from .com TLD to the .com.au TLD. Note: Each TLD is over 6 years old, we've never proactively gone after links (Penguin) and have always aimed for quality in an often spammy industry. **Have done: ** Adding HREF LANG markup to all pages on all domain Each TLD uses local vernacular e.g for the .com site is American Each TLD has pricing in the regional currency Each TLD has details of the respective local offices, the copy references the lacation, we have significant press coverage in each country like The Guardian for our .co.uk site and Sydney Morning Herlad for our Australia site Targeting each site to its respective market in WMT Each TLDs core-pages (within 3 clicks of the primary nav) are 100% unique We're continuing to re-write and publish unique content to each TLD on a weekly basis As the .co.nz site drove such little traffic re-wrting we added no-idex and the TLD has almost compelte dissapread (16% of pages remain) from the SERPs. XML sitemaps Google + profile for each TLD **Have not done: ** Hosted each TLD on a local server Around 600 pages per TLD are duplicated across all TLDs (roughly 50% of all content). These are way down the IA but still duplicated. Images/video sources from local servers Added address and contact details using SCHEMA markup Any help, advice or just validation on this subject would be appreciated! Kian
