Handling "legitimate" duplicate content in an online shop.
-
The scenario:
Online shop selling consumables for machinery.
Consumable range A (CA) contains consumables w, x, y, z. The individual consumables are not a problem, it is the consumables groups I'm having problems with.
The Problem:
Several machines use the same range of consumables. i.e. Machine A (MA) consumables page contains the list (CA) with the contents w,x,y,z. Machine B (MB) consumables page contains exactly the same list (CA) with contents w,x,y,z.
Machine A page = Machine B page = Consumables range A page
Some people will search Google for the consumables by the range name (CA). Most people will search by individual machine (MA Consumables, MB Consumables etc).
If I use canonical tags on the Machine consumable pages (MA + MB) pointing to the consumables range page (CA) then I'm never going to rank for the Machine pages which would represent a huge potential loss of search traffic.
However, if I don't use canonical tags then all the pages get slammed as duplicate content.
For somebody that owns machine A, then a page titled "Machine A consumables" with the list of consumables is exactly what they are looking for and it makes sense to serve it to them in that format.
However, For somebody who owns machine B, then it only makes sense for the page to be titled "Machine B consumables" even though the content is exactly the same.
The Question:
What is the best way to handle this from both a user and search engine perspective?

That's good solid advice. Thank you. Other ecommerce sites in the niche are nothing to write home about. Where they win is where this site has some major issues (larger than the one I'm asking about) that need fixing too.
I'm just trying to come up with a cohesive plan for a site that will blow the competition out of the water on Google (achievable) and increase sales / visitor. This is part of that.
Much as I don't like your suggestion due to the amount of work it is going to take to implement, I do think you are right and it's a better solution than the canonical tags.
That said, I suspect the canonical tags will be tried first, and then we will end up going with the content writing.

I have spent an inordinate amount of time cleaning up sites with templated pages and duplicate content. I can tell you that the potential gains are real, and the potential risks of inaction are often large.
Some text is better than no text. Google prefers a solid base of text-based content, period. It's their bread and butter and it helps them figure out what your page is about. Some time spent discussing with your team/writers how to best differentiate each page could be time very well spent. I don't know that it needs to be a solid block of prose; categories like manufacturer, machine type, year, etc. could be used in list or paragraph form (perhaps you already do this?)
You could look at other ecommerce sites that are ranking in your niche, and in others, to see what they do.
I'm not sure exactly what you mean by "The text would have to come before the products for SEO." What I will say is the position of the text on the page should probably be dictated by whatever is best for the user. Test it in different positions on the page (even the left or right sidebar) and see what converts better. I doubt if the text's position on the page will affect your rankings a great deal. As for the "boilerplate-ness," the crawlers can see if its unique or not.

I did consider that. It's in the hundreds and it could be done, but I'm not sure that's the way to go for the following reasons:
1. The number of consumables in the list is going to be at least 8 per page (each with snippet information and order box). That means that it would take a significant amount of text to make the content significantly different.
2. There is not a lot of difference between many of the machines, so writing a decent amount of text per item would be a major task. The more text written the more it affects point 3.
3. The text would have to come before the products for SEO (after the products just looks like the boilerplate-esque text that it would actually be) and that's not good for the consumer who just wants to see the consumables.
Also, we are finding more problems with the site every hour and we may not have the resources to get the text accomplished in a reasonable time-frame. Certainly, I'd have to be more certain of getting a "win" from it than I currently am before I suggest spending on it over other issues.

Ian,
Is it feasible to write unique text for the machine pages? I.e., are they in the hundreds or thousands? Do you have a budget to hire a writer(s)?
-
I may be missing something, but wouldn't canonical tags sort out your sort orders at least?
-
I have the same problem but it is listed as duplicate content within my site as a result of sort mechanisms and category pages. The consumer wants the sort mechanisms and category pages in order to find the products they are looking for quickly and I've tried everything and still have "duplicate content" listed on Moz crawls and Google Webmaster and just about everything. Imaging won't work for me since it is a result of database search mechanisms which cause the "duplicates" I also have canonical urls on pages but that doesn't solve the problem either. I think we are damned if we do and damned if we don't.

Hi Ian,
There is a way around it, but first an opinion on duplicate content. I think that duplicate content issues are really about duplication across websites, not duplication within websites. Store ABC is expected to have a fair amount of text that repeats across it's own pages. The problem arises when both Store ABC and Store LMN and Store TUV all have the same bits of content (like product descriptions).
But anyways, if you really do not want to have your lists of consumables repeated on multiple pages, just turn the lists into images....
Then on the Machine A page display the image of the list and give it a file name and alt tag like "Machine A Consumables" and "Consumables for Machine A".
And on the Machine B page display a COPY of the image of the list and give it a NEW file name and alt tag like "Machine B Consumables" and "Consumables for Machine B". Etc, etc...
For the visitor, there is no difference between reading the words from text or an image. (unless they have sight issues and are using a screen reader)
Does this solve the problem?

Categories VS Tag Duplicate Content
Hello Moz community, I have a question about categories and tags . Our customer www.elshow.pe just had a redesign of its website. We use the same categories listed before . The only change was that two sub categories were added ( these sub-categories were popular tags before ) .Then now I have 2 URL's covering the same content: The first is the URL of the subcategory : www.elshow.pe/realitys/combate/ The second is the URL that is generated by the tag "combate" that is www.elshow.pe/noticias/combate/ I have the same with the second sub category: "Esto es guerra" www.elshow.pe/realitys/esto-es-guerra/ www.elshow.pe/noticias/esto-es-guerra/ The problem is when I search the keyword "combate" in my country (Perú), the URL that positions is the tag URL in 1st page. But, when I search for "esto es guerra" the URL that positions is the **sub category **in the second page. I also check in OSE both links and sub categories goes better than tags. So what do you guys recommend for this? 301 redirect? canonicals? Any coment is welcome. Thanks a lot for your time. Italo,

Duplicate Content
Hi, I'm working on a site and I'm having some issues with its structure causing duplicate content. The first issue is that the search pages will show up as duplicates.
Technical SEO | | OOMDODigital
A search for new inventory may be new.aspx
The duplicate may be something like new.aspx=page1, or something like that and so on. The second issue is with inventory. When new inventory gets put into the stock of the store, a new page for that item will be populated with duplicate content. There appears to be no canonical source for that page. How can I fix both of these? Thanks!0 -
Duplicate Content in Wordpress.com
Hi Mozers! I have a client with a blog on wordpress.com. http://newsfromtshirts.wordpress.com/ It just had a ranking drop because of a new Panda Update, and I know it's a Dupe Content problem. There are 3900 duplicate pages, basically because there is no use of noindex or canonical tag, so archives, categories pages are totally indexed by Google. If I could install my usual SEO plugin, that would be a piece of cake, but since Wordpress.com is a closed environment I can't. How can I put a noindex into all category, archive and author peges in wordpress.com? I think this could be done by writing a nice robot.txt, but I am not sure about the syntax I shoud use to achieve that. Thank you very much, DoMiSol Rossini

Taking descriptions from Manufacturer sites and Duplicate content
We are doing some inventory improvements eg new photographs from various angles, etc. We are also writing descriptions for each product.. As one of our suppliers has perfect desriptions on their site what is the theory on how duplicate content will affect our ranking for these products if we copy and paste? Also if we change the descriptions, just how different do they need to be? Thanks

CGI Parameters: should we worry about duplicate content?
Hi, My question is directed to CGI Parameters. I was able to dig up a bit of content on this but I want to make sure I understand the concept of CGI parameters and how they can affect indexing pages. Here are two pages: No CGI parameter appended to end of the URL: http://www.nytimes.com/2011/04/13/world/asia/13japan.html CGI parameter appended to the end of the URL: http://www.nytimes.com/2011/04/13/world/asia/13japan.html?pagewanted=2&ref=homepage&src=mv Questions: Can we safely say that CGI parameters = URL parameters that append to the end of a URL? Or are they different? And given that you have rel canonical implemented correctly on your pages, search engines will move ahead and index only the URL that is specified in that tag? Thanks in advance for giving your insights. Look forward to your response. Best regards, Jackson
