Product Category Subcategory hierarchy
-
Hi all,
I am developing an ecommerce store and would like some advice on the Category / Product URL structure for SEO purposes.
- Products have many options
- Products belong to a sub-category.
- Sub categories belong to a category
There will be a maximum of 500 products in the database.
1. http://shop.com/{category}/{product_slug}?{product_option} Flattened with query string option
2. http://shop.com/{category}/{subcategory}/{product_slug}?{product_option} // Hierarchical with query string option
3. http://shop.com/{category}/{product_slug}/{product_option}
4. http://shop.com/{category}/{subcategory}/{product_slug}/{product_option}
Option 5 seems best to me, however I am also worried about duplicate content between pages.
- http://shop.com/apple/iphone-5s-32gb-black
- http://shop.com/apple/iphone-5s-64gb-black
- http://shop.com/apple/iphone-5s-64gb-white
The above 3 examples will all have very similar content. And if I use canonical url tag, which product page would I refer these pages to?
At least with Option 1 I can use the canonical tag to tell search engines that pages with get parameters can point to the non get parameter version.
In addition to Option 5, should I create a http://shop.com/{category}/{subcategory} page? That way Option 5 item canonical tags can point to that page. e.g. http://shop.com/apple/iphone-5s which would contain product summary detail with product options listed on the page?
Am I missing something here or can anybody provide a better solution?

I typically keep category names out of the product URL. It creates problems, especially when the product lives in multiple categories. You can use a rel canonical tag, but I'd rather just not have to deal with it. Here is how I do it:
www.domain.com/products/product-name/
www.domain.com/category/category-name/ and
www.domain.com/category/category-name/sub-category-name/This convention has several advantages, including easy segmentation of the site to determine, for instance, how many product pages are indexed in the SERPs.
One could argue that having the category name in the product URL is good for SEO because of the keywords, but I would argue that putting the product farther down in the site structure, and the non-canonical URL issues related to certain taxonomies (e.g. multiple categories for a product) negates what little benefit keywords in the URL have these days.
Of course not all eCommerce platforms really allow the structure above. Magento, for example, will allow you to put products in the root, but not in the /product/ folder. The product will also be viewable on the category-version of the URLs, but they will have a rel canonical tag pointing to the root directory version.
Good luck.

Topical keywords for product pages and blogs
Hi all, I have a question regarding keywords. Of course we all know that keyword research should be focused on a certain topic and on user intent (and thus on answering specific questions) instead of trying to put keywords in a page to make it rank. However, duplicate content is of course still an issue. So here's my question: A client that sells floor heating systems that you can install yourself, has a product page for this topic and blog pages for questions regarding this topic. So following pages are on the website: Product page about the floor heating systems the client sells Blog article with tips how to install a floor heating system yourself Blog article about how to choose the right floor heating system These pages all answer different questions and are written about different topics. However, inevatibly all these pages also talk about different aspects of floor heating systems so this broad term comes up on all pages naturally. You could say that a solution is to merge pages and redirect the blogs to the product page, so the product page would answer all questions. But that is not what a customer is looking for. The goal of a product page is to trigger a conversion: let a customer contact the company or ask for a price offer. If the content on a product page is not comprehensive enough, the goal gets lost. Moreover, it doesn't make sense to talk about tips and tricks on a product page. So how do you tackle this problem without creating duplicate content? In search results, the blog pages rank for the specific questions, but the product page doesn't rank for the generic term 'floor heating'. The internal link structure is ok: the product page has obviously more incoming links than the blogs. All on page SEO factors are taken care of as well. Any ideas on this? Thanks!

Should I noindex my categories?
Hello! I have created a directory website with a pretty active blog. I probably messed this up, but I pretty much have categories (for my blog) and custom taxonomy (for different categories of services) that are very similar. For example I have the blog category "anxiety therapists" and the custom taxonomy "anxiety". 1- is this a problem for google? Can it tell the difference between archive pages in these different categories even though the names are similar? 2- should I noindex my blog categories since the main purpose of my site is to help people find therapists ie my custom taxonomy?

Canoncial tag for Similar Product Descriptions on Woocommerce
I'm looking for advice on how to handle my product description pages for my website vinylabs.com. The website sells vinyl wrap for cars and each color of vinyl (89 variations) has it's own product page. The product descriptions will all be identical except for the color description and code. All of our competitors have an identical layout, different pages for each color, and it fits the product so I don't want to depart from featuring each color as it's own page. Here is my dilemma. I don't want to get penalized for duplicate content, however I do want individual color codes to be searchable on google. For example if you google 3M vinyl wrap M203 you'll get individual pages from the manufacturer and our competitors featuring just that color. I want our website to show up as well. I was thinking about creating a single page that has selectable colors and sizes and then using the canonical tag to point all of my individual color code pages to that single page. However won't that hurt the ability for my individual color code pages to show in search? None of my competitors are using the canonical tag to redirect to a different page. Any advice welcome! Thank you for your time.

How to handle brand description on product pages?
Hi Mozzers, Hope you're doing good. I have a content placement related question. Assume, I have 1000 products of brand A, 1000 of brand B, and so on. Now, if I want to put brand specific 200-words description on each of these product pages.

Looking for an expert advice around placement of content here i.e how can I add brand description on product pages and avoid duplicate content penalty? Any help?

Thinking about not indexing PDFs on a product page
Our product pages generate a PDF version of the page in a different layout. This is done for 2 reasons, it's been the standard across similar industries and to help customers print them when working with the product. So there is a use when it comes to the customer but search? I've thought about this a lot and my thinking is why index the PDF at all? Only allow the HTML page to be indexed. The PDF files are in a subdomain, so I can easily no index them. The way I see it, I'm reducing duplicate content On the flip side, it is hosted in a subdomain, so the PDF appearing when a HTML page doesn't, is another way of gaining real estate. If it appears with the HTML page, more estate coverage. Anyone else done this? My knowledge tells me this could be a good thing, might even iron out any backlinks from being generated to the PDF and lead to more HTML backlinks Can PDFs solely exist as a form of data accessible once on the page and not relevant to search engines. I find them a bane when they are on a subdomain.

Should I change my product titles from singular to plural to satisfy optimisation?
At present most of our products are listed in the singular form. http://www.towelsrus.co.uk/towels-bath-towels/aztex/turkish-cotton-bath-towel_ct473bd182pd2744.htm However we are optimising for the plural form after carrying out keyword research The question is should I update the product title to reflect this change? This would then change the URL of the page, H1 tag, H2 tag (both auto generated from the product title) My concern here is that these pages will then become "new pages" and will need to index and rank, albeit they don't rank well as they have never been optimised until now. I could put 301 re-directs in place on the old URL's or i could just let the return a 404. What do people think?
