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

Is it Ok to have multiple domains (separate website different content) rank for similar keywords?
Is it 'OK' to have multiple domains in the following instance? Does Google actively discourage multiple (but completely different sites) domains from the same company appearing in the search results for the same and or similar keywords if the content is slightly different? This is where the 'main site' has the details, and you can purchase product, and the second site is a blog site only. We are creating a separate content blogsite; which would be on a second domain that will be related to one portion of content on main site. They would be linking back and forth, or maybe the blog site would just link over to the main site so they can purchase said product. This would be a similar scenario to give you an idea of how it would be structured: MAIN SITE: describes a few products, and you can purchase from this site SECOND SITE, different domain: a blog site that contains personal experiences with one of the products. BOTH sites will be linked back and forth....or as mentioned maybe the blog site could just link over to the 'main site' Logo would be a modified version of the main logo and look and feel of the sight would be similar but not exactly the same. MORE INFO: the main site has existed for way over 10 years, starting to gain some traction in an extremely competitive market, but does not rank super high, is gaining traction due to improvements in speed, content, onpage SEO, etc... So in addition to my main question of is this 'ok' to have this second domain, also will it hurt the rankings or negatively affect the 'main' site? Wondering about duplicate content issues, except it will be slightly different...

Could another site copying my content hurt my ranking?
Earlier this week I asked why a page of mine might not be ranking locally. (https://moz.com/community/q/what-could-be-stopping-us-from-ranking-locally). Maybe this might be part of the answer – another firm has copied huge chunks of my website copy: **My company: **https://idearocketanimation.com/video-production-company/ The other company: http://studio3dm.com/studio3dm-com/video/ Could this be causing my page to not rank? And is there anything I can do about it, other than huff and puff to the other firm? (Which I am already doing.)

Duplicate Content through 'Gclid'
Hello, We've had the known problem of duplicate content through the gclid parameter caused by Google Adwords. As per Google's recommendation - we added the canonical tag to every page on our site so when the bot came to each page they would go 'Ah-ha, this is the original page'. We also added the paramter to the URL parameters in Google Wemaster Tools. However, now it seems as though a canonical is automatically been given to these newly created gclid pages; below https://www.google.com.au/search?espv=2&q=site%3Awww.mypetwarehouse.com.au+inurl%3Agclid&oq=site%3A&gs_l=serp.3.0.35i39l2j0i67l4j0i10j0i67j0j0i131.58677.61871.0.63823.11.8.3.0.0.0.208.930.0j3j2.5.0....0...1c.1.64.serp..8.3.419.nUJod6dYZmI Therefore these new pages are now being indexed, causing duplicate content. Does anyone have any idea about what to do in this situation? Thanks, Stephen.

Removing duplicate content
Due to URL changes and parameters on our ecommerce sites, we have a massive amount of duplicate pages indexed by google, sometimes up to 5 duplicate pages with different URLs. 1. We've instituted canonical tags site wide. 2. We are using the parameters function in Webmaster Tools. 3. We are using 301 redirects on all of the obsolete URLs 4. I have had many of the pages fetched so that Google can see and index the 301s and canonicals. 5. I created HTML sitemaps with the duplicate URLs, and had Google fetch and index the sitemap so that the dupes would get crawled and deindexed. None of these seems to be terribly effective. Google is indexing pages with parameters in spite of the parameter (clicksource) being called out in GWT. Pages with obsolete URLs are indexed in spite of them having 301 redirects. Google also appears to be ignoring many of our canonical tags as well, despite the pages being identical. Any ideas on how to clean up the mess?

Where is the best place to put a sitemap for a site with local content?
I have a simple site that has cities as subdirectories (so URL is root/cityname). All of my content is localized for the city. My "root" page simply links to other cities. I very specifically want to rank for "topic" pages for each city and I'm trying to figure out where to put the sitemap so Google crawls everything most efficiently. I'm debating the following options, which one is better? Put the sitemap on the footer of "root" and link to all popular pages across cities. The advantage here is obviously that the links are one less click away from root. Put the sitemap on the footer of "city root" (e.g. root/cityname) and include all topics for that city. This is how Yelp does it. The advantage here is that the content is "localized" but the disadvantage is it's further away from the root. Put the sitemap on the footer of "city root" and include all topics across all cities. That way wherever Google comes into the site they'll be close to all topics I want to rank for. Thoughts? Thanks!

Artist Bios on Multiple Pages: Duplicate Content or not?
I am currently working on an eComm site for a company that sells art prints. On each print's page, there is a bio about the artist followed by a couple of paragraphs about the print. My concern is that some artists have hundreds of prints on this site, and the bio is reprinted on every page,which makes sense from a usability standpoint, but I am concerned that it will trigger a duplicate content penalty from Google. Some people are trying to convince me that Google won't penalize for this content, since the intent is not to game the SERPs. However, I'm not confident that this isn't being penalized already, or that it won't be in the near future. Because it is just a section of text that is duplicated, but the rest of the text on each page is original, I can't use the rel=canonical tag. I've thought about putting each artist bio into a graphic, but that is a huge undertaking, and not the most elegant solution. Could I put the bio on a separate page with only the artist's info and then place that data on each print page using an <iframe>and then put a noindex,nofollow in the robots.txt file?</p> <p>Is there a better solution? Is this effort even necessary?</p> <p>Thoughts?</p></iframe>

PDF for link building - avoiding duplicate content
Hello, We've got an article that we're turning into a PDF. Both the article and the PDF will be on our site. This PDF is a good, thorough piece of content on how to choose a product. We're going to strip out all of the links to our in the article and create this PDF so that it will be good for people to reference and even print. Then we're going to do link building through outreach since people will find the article and PDF useful. My question is, how do I use rel="canonical" to make sure that the article and PDF aren't duplicate content? Thanks.
