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.

Archive pages structure using a unique hierarchical taxonomy, could be good for SEO?
Hi, Preamble:
Intermediate & Advanced SEO | | danielecelsa
We are creating a website where people look for professionals for some home working. We want to create a homepage with a search bar where people write the profession/category (actually it is a custom taxonomy) that they need, like ‘plumbers’, and a dropdown/checkbox filter where they can choose the city where they need the plumber.
The result page is a list of plumber agencies in the city chosen. Each agency is a Custom Post Type for us. Furthermore, we are hardly working to make our SEO ranking as high as possible.
So, for example, we know that it is important to have a well-done Archive Page for each Taxonomy term, besides a well-done Results Page.
Also, we know it is bad for SEO to have duplicated pages or (maybe) similar pages, ranking for the same (or maybe also similar) keywords. Proposed Structure:
So, what we are thinking is to have this structure:
A unique hierarchical taxonomy that INCLUDES the City AND the profession! That means that our taxonomy ‘taxonomy_unique’ has terms like: ‘Rome’, ‘Paris’, ‘Dublin’ as father and also terms like ‘Plumbers’, ‘Gardeners’, ‘Electricians’ which are sons of some City father! So we will have the term 'Plumbers' son of 'Rome' and we will have also the term 'Plumbers' son of 'Paris'. Each of these two taxonomy terms (Rome/Plumbers and Paris/Plumbers) will have an archive page that we want to make ranking for the keywords ‘Plumbers in Rome’ and ‘Plumbers in Paris’ respectively. It is easier to think of it imagining the breadcrumbs. They will be:
Home > Rome > Plumbers
and
Home > Paris > Plumbers Both will have: a static content (important for SEO), where we describe the plumber profession with a focus on the city, like ‘Find the best Plumbers in Rome’ vs ‘Find the best Plumbers in Paris' a 'dynamic' content - below - that is a list of Custom Post Types which have that taxonomy term associated. Furthermore, also 'Rome' and 'Paris' are taxonomy terms that have their own archive page. In those pages, we are thinking to show the Custom Post Types (agencies) associated with that taxonomy term as a father OR maybe just a list of the 'sons' of that father, so links to those archive pages 'sons').
In both cases, there should be also a static content talking maybe about the city and the professionals it offers in general. Questions:
So what we would like to understand is: Is it bad from an SEO perspective to have 2 URLs that look like this:
www.mysite.com/Rome/Plumbers
and
www.mysite.com/Naples/Plumbers
where the static content is really similar and it is something like that:
“Are you looking for the best plumbers in the city of Rome”
and
“Are you looking for the best plumbers in the city of Naples”? Also, these kinds of pages will be much more than 2, one for each City.
We are doing that because we want the two different pages to rank high in two different cities, but we are not sure if Google likes that. On the other hand, each City will have one page for each kind of job, so:
www.mysite.com/Rome/Plumbers
www.mysite.com/Rome/Gardeners
www.mysite.com/Rome/Electricians
So the same question, does Google like this or not? About 'Rome' and 'Paris' archive pages, does Google prefer a list of Custom Post Types that have that father term associated as taxonomy, or a list of the archive pages 'sons', with links to those pages? What do you think about this approach? Do you think this structure could be good from an SEO perspective, or maybe there could be something better alternatively? Hoping everything is clear, we really appreciate anyone dedicating its time and leaving feedback.

Rel-canonical vs Href-lang use for an international website.
I have a multi-country website that uses country subfolders to separate countries. When I run a Moz scan, I am getting canonical related alerts (this is probably related to some of our US content being duplicated on the other country websites). Shouldn't I be using href-lang instead since I am telling search engines that a certain article in country B, is just a copy of the same article in country A?

We have set up our H1 to contain the product name - it used to be our Company name all the time - would this affect our sales
We noticed recently on our site - that our H1 tag was the Company Name - we changed this to be the product name - our products would be searched for by all or part of the description. Our sales have dropped of the days since we changed it, could it be a result of this change ? Is it best to have the H1 tag as the product name ?

Duplicate Title tags even with rel=canonical
Hello, We were having duplicate content in our blog (a replica of each post automatically was done by the CMS), until we recently implemented a rel=canonical tag to all the duplicate posts (some 5 weeks ago). So far, no duplicate content were been found, but we are still getting duplicate title tags, though the rel=canonical is present. Any idea why is this the case and what can we do to solve it? Thanks in advance for your help. Tej Luchmun

How to rank product pages?
Hi guys, Please advice me on something improving my product pages ranking. We are doing well for head terms, categories but not ranking for product pages. We have issues with product pages which I am think is hard to tackle. For instance we have duplicate products (different colors), duplicate content internally (colors) and from manufacturer websites. Product pages linked from sub-category i.e. Home > Category > Sub-Category (20 per page) using pagination for next 20 and so on. Product pages linked internally via widgets that says other Similar products, featured products etc. Another issue with our product pages is that we are using third party reviews platform and whenever users add reviews to product pages this platform creates an hyperlink to different anchors which is not relevant to product. Example - http://goo.gl/NUG652 Can somebody please give some advice on how to improve rankings for product pages. writing unique content for thousands of pages is not possible. Even our competitor not writing unique content.

Duplicate on page content - Product descriptions - Should I Meta NOINDEX?
Hi, Our e-commerce store has a lot of product descriptions duplicated - Some of them are default manufacturer descriptions, some are descriptions because the colour of the product varies - so essentially the same product, just different colour. It is going to take a lot of man hours to get the unique content in place - would a Meta No INDEX on the dupe pages be ok for the moment and then I can lift that once we have unique content in place? I can't 301 or canonicalize these pages, as they are actually individual products in their own right, just dupe descriptions. Thanks, Ben

Use of rel="alternate" hreflang="x"
Google states that use of rel="alternate" hreflang="x" is recommended when: You translate only the template of your page, such as the navigation and footer, and keep the main content in a single language. This is common on pages that feature user-generated content, like a forum post. Your pages have broadly similar content within a single language, but the content has small regional variations. For example, you might have English-language content targeted at readers in the US, GB, and Ireland. Your site content is fully translated. For example, you have both German and English versions of each page. Does this mean that if I write new content in different language for a website hosted on my sub-domain, I should not use this tag?
