Should I use rel=canonical on similar product pages.
-
I'm thinking of using rel=canonical for similar products on my site.
Say I'm selling pens and they are al very similar. I.e. a big pen in blue, a pack of 5 blue bic pens, a pack of 10, 50, 100 etc. should I rel=canonical them all to the best seller as its almost impossible to make the pages unique. (I realise the best I realise these should be attributes and not products but I'm sure you get my point)
It seems sensible to have one master canonical page for bic pens on a site that has a great description video content and good images plus linked articles etc rather than loads of duplicate looking pages.
love to hear thoughts from the Moz community.

There's no perfect solution, but Google's advice is to use rel=prev/next. This looks like pretty classic pagination. Rel-canonical is a stronger signal, but it's generally going to keep pages 2+ from ranking.

Dr. Pete,
I have a internal debate going and I was hoping you might be a tie breaker on rel=canonical vs noindex given these paginated pages and might be a good use case for others:

https://www.newhomesource.com/communityresults/market-269/citynamefilter-cedar-park/page-2
The individual list items are unique, but clearly want to rank for essentially the exact same terms. Page titles, metas, copy about cit is the same. Just the list elements are different, but not a 12 pack of pens, 24 pack etc. Is this tricky or clear?

Thank you Sir. I think we reached the same conclusion.
By the way, the it was a just a simple example of the page hierarchy - we're not doing Horror Books

I haven't heard any SEO recommendations or benefits regarding rel="contents". Rel=prev/next has mixed results, but I'd generally only use it for its specific use case of paginated content.
I guess you could treat V2 as "pages" within V1. If you did that, what you'd need to do is treat the main page as a "View All" page and link to it from each author page. I'm not sure if that's the best approach, but it's more or less Google-approved.
If the site has decent authority and we're only talking 100s of pages, I might let them all live in the index and see what happens. Let Google sort it out, and then decide if you're ok with the outcome. If the site is low authority and/or we're talking 1000s of pages, I might be more cautious.
It's hard to speak in generalities - it depends a lot on the quality of the site and nature of the pages, including how much that content is available/duplicated across the web. One problem here is that author pages with lists of books probably exist on many sites, so you have to differentiate yourself.

Good. Same page
I was looking in to rel=contents and those variations before, but I can't quite decide whether this is worth the effort or not.
e.g. There's a huge list of resources on a single page, segmented in to categories. The page is HUGE and takes ages to load, so I've been creating new pages for each segment and optimising those pages independently, but there is some common content with the primary page.
V1: Horror Novels page has a section for each author, each section lists all novels by that author.
V2: Each Author has a page which lists novels by that author, but links back to the Horror Novels page which is essentially an index of the Author pages. Would you also
Would you use rel=contents, rel=prev/next or a different approach in this case? From what I've read so far, there doesn't seem any "SEO value" in linking that way.
I guess we're trying to improve the UX through faster load times and segmenting the information in smaller chunks, but also presenting a number of pages to Google as a body of content rather than a single page without causing issues with duplicate or similar content - we just need to make sure that we're optimising it in the right way, of course.
-
I would Meta Noindex an "email this page" template. It has no value for SERPs, it's generally at the end of a path, and no one is going to link to it. Just keep it out of the index altogether.
-
Thanks Pete
So, for a more specific example, if an eCommerce store has an "email this product" page for each product (Magento seems to love doing this and creates a duplicate of the same email page for every product), would you recommend a canonical link for each of those pages to the main Contact page or canonically linking each page to each related product page?
From setup, I'd consider NoIndex on all of those pages anyway, but it's a bit late for that once a site has been live for years.
The email pages are obviously related to the product page, but the content there isn't anywhere near identical.
Or maybe there's a "more appropriate solution" that you alluded to?
-
To clarify, that's the official stance - rel=canonical should only be used on true duplicates (basically, URL variants of the same page). In practice, rel=canonical works perfectly well on near-duplicates, and sometimes even on wildly different pages, but the more different you get, the more caution you should exercise. If the pages are wildly different, it's likely there are more appropriate solutions.
-
Hey Pete
Can you explain, "you can't use rel=canonical on pages that aren't 100% duplicates" a little further please?
Do you mean that only duplicate pages should be canonicalised? Identical pages in two different sub-directories is fine, but two similar pages is not?
-
So, here's the problem - if you follow the official uses of our options, then there is no answer. You can't have thin content or Google will slap you with Panda (or, at the very least, devalue your rankings, you can't use rel=canonical on pages that aren't 100% duplicates, and you're not supposed to (according to Google) just NOINDEX content. The official advice is: "Let us sort it out, but if we don't sort it out, we'll smack you down."
I don't mean that to be critical of your comment, but I'm very frustrated with the official party line from Google. Practically speaking, I've found index control to be extremely effective even before Panda, and critical for big sites post-Panda. Sometimes, that means embracing imperfect solutions. The right tool for any situation can be complex (and it may be a combination of tools), but rel=canonical is powerful and often effective, in my experience.
-
It seems to me that for most ecommerce sites (myself included) that canonical is not the answer. If you have to many near identical products on your site it may be better to re evaluate what you have stocking and if you must stock them then the way forward is to make one page that properly explains them and allows purchase rather than many.
The only uses I can see for canonical is to consolidate old blogs and articles on similar topics. Using it to tidy an ecommerce site seems to be a misuse of the tool.
-
This can get tricky when you dive into the details, but I general agree with Takeshi and EGOL - consolidate or canonicalize. If the products are different brands/versions of a similar item, it's a bit trickier, but these variations do have a way of spinning out of control. In 2013, I think the down side of your index running wild is a lot higher than the up side of ranking for a couple more long-tail terms. It does depend a lot on your traffic, business model, etc., though. I'm not sure any of us can adequately advise you in the scope of a Q&A.
-
Also I forgot to mention that in this way you also don't have to worry about creating tons of different product descriptions because you will put one description for, let's say, 6 different products.
the way we built it, allow us to have just product group pages are reachable; the products pages are indexed and crawled and they have to be there otherwise the whole system wouldn't work, but no optimization is done on them and customers can't see it.

Hello there,
I manage an e-commerce site and because we have similar products and issues with duplicate content we have implemented product groups pages with a drop-down menu' listing the different options for a particular product and then we have used the rel="canonical" with the different product pages. In this way we have solved this issue and it works very well.
If you do implement it, make sure every passage is done correctly otherwise, as Matt Cutts says, you will have an headache trying to sort it out.
Hope it helps

Those pen offers are very very similar. Identical product descriptions except for perhaps number being sold or color or width of the tip.
If these were on my site they would all be on the same page. One page to concentrate/conserve the linkjuice. One page to make thicker content. One page to present all of the options to the customer at same time. (PITA to click between lots of pages to make up your mind as a shopper). One page to make maintenance easy.
-
Thanks

Yes, I've used this approach for a number of ecommerce clients, and it is very effective. There are many advantages to this approach:
- Eliminating duplicate/thin content across the site
- Focusing link value on a single page instead of spreading out across multiple products
- Less effort creating unique content (one page vs multiple)
- Potentially better user experience
Of course, if you have the resources to write unique content for each of your product pages, that is going to be a better solution. You can still create a landing page in this instance, you just wouldn't canonical the product pages to it.
-
Have you used this approach? If so how effective is it?
-
If you want to rank for "flat head screw driver", the canonical approach can still work. Simply create a landing page for flat head screw drivers, and include all of the flat head screwdriver products from each of the different brands. Then canonical each of the individual product pages up to the main landing page.
-
I have all the usual colour size attributes on my products. I just used that as a simple example. Its more to do with similar non branded products that are different enough to be "products" but not when I have 15 similar it's impossible to write fully different descriptions. Screwdrivers, screws or paint would have been a better example. There are hundreds of ranges like that. If you had five unimportant brands of screwdriver and you had flat head and philips head. Each one is marginally different (handle style etc) but there is no keyword benefit to having each optimised for say "flat head screwdriver". Having a good range is beneficial to the customer but seems to be detrimental to SEO. Is it better to employ writers to make every description different no matter how complex or should I canonical it?
-
Yes, that is a good solution, especially in this post-Panda world. Ideally you would just have one page for Bic pens, with a drop down from which you can select different options such as colors & size. If your shopping cart system doesn't allow you to do that, then the canonical is a good approach. This cuts down on the amount of duplicate content you have and the amount of unique content you need to create.
-
Have a client in the exact same situation. Check to see if you are currently getting traffic for terms that would be specific to having separate pages (e.g. "50 blue bic pens" versus a more general "bic blue pens"). If you don't, then you should canonical to one page. If you do, I'd keep it as is and work on diversifying the product pages more.

Shall we add engaging and useful FAQ content in all our pages or rather not because of duplication and reduction of unique content?
We are considering to add at the end of alll our 1500 product pages answers to the 9 most frequently asked questions. These questions and answers will be 90% identical for all our products and personalizing them more is not an option and not so necessary since most questions are related to the process of reserving the product. We are convinced this will increase engagement of users with the page, time on page and it will be genuinely useful for the visitor as most visitors will not visit the seperate FAQ page. Also it will add more related keywords/topics to the page.

On the downside it will reduce the percentage of unique content per page and adds duplication. Any thoughts about wether in terms of google rankings we should go ahead and benefits in form of engagement may outweight downside of duplication of content?0 -
Is there a way to rel = canonical only part of a page?
Hi guys: I'm doing SEO for a boat accessories store, and for instance they have marine AC systems, many of them, and while the part number, number of BTUs, voltage, and accessories change on some models, the description stays exactly the same across the board on many of them...people often search on Google by model number, and I worry that if I put rel = canonical, then the result for that specific model they're looking for won't come up, just the one that everything is being redirected to. (and people do this much more than entering a site nowadays and searching by product model, it's easier). Excuse my ignorance on this stuff, I'm good with link building and content creation, but the behind-the-scenes aspects... not so much: Can I "rel=canonical" only part of the page of the repeat models (the long description)? so people can still search by model number, and reach the model they are looking for? Am I misunderstanding something here about rel=canonical (Interesting thing, I rank very high for these pages with tons of repeat descriptions, number one in many places... but wonder if google attributes a sort of "across the site" penalty for the repeated content... but wouldn't ranking number 1 for these pages mean nothing's wrong?. Thanks)

Using cononical and rel=next / prev for single page app
Hi, We are currently working on a single page ember.js website which compares LED light bulbs (seriously...) the site is www.whichledlight.com the problem in question is www.whichledlight.com/bulbs we are using both rel=next/prev as well as cononical and wondering what affect this would have? all the canonical reference themselves I think, and are also present on the product pages. Our google impressions have dropped recently as well, so we are wondering wether or not this is having a negative affect in regards to how well google wants to play with us. Any ideas?

Is it ok to add rel=CANONICAL into the desktop version on top of the rel="alternate" Tag (Mobile vs Desktop version)
Hi mozzers, We launched a mobile site a couples months ago following the parallel mobile structure with a URL:m.example.com The week later my moz crawl detected thousands of dups which I resolved by implementing canonical tags on the mobile version and rel=alternate onto the desktop version. The problem here is that I still also got Dups from that got generated by the CMS. ?device=mobile ?device=desktop One of the options to resolve those is to add canonicals on the desktop versions as well on top of the rel=alternate tag we just implemented. So my question here: is it dangerous to add rel=canonical and rel=alternate tags on the desktop version of the site or not? will it disrupt the rel=canonical on mobile? Thanks

Rel Canonical on Home Page
I have a client who says they can't implement a 301 on their home page. They have tow different urls for their home page that are live and do not redirect. I know that the best solution would be to redirect one to the main URL but they say this isn't possible. So they implemented the rel canonical instead. Is this the second best solution for them if they can't redirect? Will the link juice be passed through the rel canonical? Thanks!

Is it ok to use both 301 redirect and rel="canonical' at the same time?
Hi everyone, I'm sorry if this has been asked before. I just wasn't able to find a response in previous questions. To fix the problems in our website regarding duplication I have the possibility to set up 301's and, at the same time, modify our CMS so that it automatically sets a rel="canonical" tag for every page that is generated. Would it be a problem to have both methods set up? Is it a problem to have a on a page that is redirecting to another one? Is it advisable to have a rel="canonical" tag on every single page? Thanks for reading!

Duplicate Content on Product Pages
I'm getting a lot of duplicate content errors on my ecommerce site www.outdoormegastore.co.uk mainly centered around product pages. The products are completely different in terms of the title, meta data, product descriptions and images (with alt tags)but SEOmoz is still identifying them as duplicates and we've noticed a significant drop in google ranking lately. Admittedly the product descriptions are a little bit thin but I don't understand why the pages would be viewed as duplicates and therefore can be ranked lower? The content is definitely unique too. As an example these three pages have been identified as being duplicates of each other. http://www.outdoormegastore.co.uk/regatta-landtrek-25l-rucksack.html http://www.outdoormegastore.co.uk/canyon-bryce-adult-cycling-helmet-9045.html http://www.outdoormegastore.co.uk/outwell-minnesota-6-carpet-for-green-07-08-tent.html
