Canonicalising a product with multiple variants
-
I am working with an ecommerce site and have encountered an issue I haven't come across before and would appreciate some advice on how to proceed.
There are multiple variation products with one master product and then up to 20 or 30 variant products, the variation could be colour, size or both. The site has been set up to canonicalise all the variations to the master variant product, which I understand to be best practice. But, this is where the issue occurs, the master variant product URL 302 redirects to one of the variant product URLs. Example below. My question is, is this harmful to our SEO efforts? Would be be best to canonicalise to a preferred colour or size variation?
EXAMPLE:
Master variant product: www.example.co.uk/primary-category/product-123
Seeing this product on the page and clicking will 302 redirect to www.example/co.uk/primiary-category/product-123/colour-456
On page www.example/co.uk/primiary-category/product-123/colour-456 the canonical tag is www.example.co.uk/primary-category/product-123
Any help with this would be greatly appreciated.

Hi Nick,
Thanks for your response. At the moment we have around 2000 products and some of the canonical pages do rank, others don't so it does seem the search engine in confused.
The article on SiteBulb is really interesting and I agree with your reasoning to canonicalise to either the most vanilla or popular product variant.
Many thanks,
Simon

Hi Simon,
Quick question which I think I can guess the answer, does the current canonical page rank for anything at all?
Can't the developers make the canonical a static page (which currently redirects) default to the most popular and or a vanilla combination of product attributes?
That would of course be the best option, failing that you would have to just canonicalise to the most popular product variation and do so in a way that doesn't create a redirect chain.
I literally just referenced SiteBulb in another post, and I don't want to come across like a shill but there's a great explanation of it your issue here: https://sitebulb.com/hints/indexability/canonical-hints/canonical-points-to-a-redirecting-url/
Easier said than done for sure with some CMS and E-Commerce sites, but as the aforementioned link says...it's generally dealt with on a case by case basis.
Appreciate this is isn't a definitive answer but I hope it helps!
Nick

Multiple H1s and Header Tags in Hero/Banner Images
I work on education websites, and our sites are being flagged by SEO and accessibility checkers for having multiple H1s. The home pages have the site name as an h3 in the hero image, and an aspirational headline (think: Be Like Mike) as an H1. The sub-pages have two H1s: one on the site name in the banner image, and the other on the page title. Note that the site name is very keyword-rich. If we were to remove the H1 and H3 tags from the hero/banner images, would it do any SEO harm? At the same time, we’d rewrite the H1 on the home page to be more keyword-focused. Any other options? I also read that it’s OK to have multiple H1s as long as it’s clear which H1 belongs to the heading area and which one belongs to the body area of the page. Thanks in advance!

NOINDEX, FOLLOW on product page - how about images indexing?
Hi, Since we have a lot of similar products with duplicate descriptions, I decided to NOINDEX, FOLLOW most of these different variants which have duplicate content. However, I guess it would be useful in marketing terms if Google image search still listed the images of the products in image search. How does the image search of Google actually work - does it read the NOINDEX on the product page and therefore skip the image also or is the image search completely dependent on the ALT tag of any image found on our site? Thanks!

Duplicate Content Re: Product listing body copy on Website, Amazon & Ebay - issues ?
Hi Is it ok to have identical product body copy on market/platform listings same as the websites product listings ? In this case the products are the websites/own brand products (all pages canonicalised), so i take it shouldn't cause any issues or are you supposed to differentiate the product body copy on marketplace listings ? Im asking re seo reasons All Best Dan

How many product subcategories are ok?
Let's say I have a sea glass ankle bracelet. On my site, my main keyword is "Sea Glass Jewelry" and have ranked relatively well for this, but this main page has over 200 products in it. I thought that if the URL has the keywords in it, it would be beneficial. I also have a section for all my bracelets, so it would be there and then, a more specific ankle bracelets category. So, technically, an ankle bracelet will show up 3x. Sea Glass Jewelry (all products go here) Bracelets (all bracelets go here) Ankle Bracelets (only ankle bracelets) The URL is only attached to the main category so to speak. If you click the ankle bracelets category, the url will still revert back to the original main category: seaglassjewelry/sterlinganklebracelet so I don't believe there is duplicate content. I have had my domain for years and it has ranked well until someone hacked into my site 2 years back. I have never been able to recover from this loss. Since then, I have tried to optimize my site, but nothing seems to be working and I just want to make sure that I am not hurting my ranking by doing this. Can someone confirm this is the best way to do it or make a suggestion? Thank you.

Should I add PDF manuals to my product pages?
Hello. A lot of the products I sell on my e-commerce site are very technical. I decided to add PDF data sheets, manuals etc on each of the product pages to improve the customer experience. Now I am not sure if it was the best thing to do. I have noticed a couple of times that the PDF is out ranking the product page in the SERP. For a few products, the PDF ranks but the product page doesn't. Anyone got any ideas?

Add content as blog post or to product pages?
Hi, We have around 40 products which we can produce plenty of in-depth and detailed "how to"-type pieces of content for. Our current plan is to produce a "How to make" style post for each as a long blog post, then link that to the product page. There's probably half a dozen or more of these kind of blog posts that we could do for each product. The reason why we planned on doing it like this is that it would give us plenty of extra pages (blog posts) on their own URL which can be indexed and rank for long tail keywords, but also that we can mention these posts in our newsletter. It'd give people a new page full of specific content that they can read instead of us having to say "Hey! We've updated our product page for X!", which seems a little pointless. Most of the products we sell don't get very many searches themselves; Most get a couple dozen and the odd few get 100-300 each, while one gets more than 2,000 per month. The products don't get many searches as it's a relatively unknown niche when it comes to details, but searches for the "categories" these products are in are very well known (Some broad terms that cover the niche get more than 30,000+ searches a month in the UK and 100,000+ world wide) [Exact].

Regarding the one product with more than 2,000 searches; This keyword is both the name of the product and also a name for the category page. Many of our competitors have just one of these products, whereas we're one of the first to have more than 6 variations of this product, thus the category page is acting like our other product pages and the information you would usually find on our product pages, is on the category page for just this product. I'm still leaning towards creating each piece of content as it's own blog post which links to the product pages, while the product pages link to the relevant blog posts, but i'm starting to think that it may be be better to put all the content on the product pages themselves). The only problem with this is that it cuts out on more than 200 very indepth and long blog posts (which due to the amount of content, videos and potentially dozens of high resolution images may slow down the loading of the product pages). From what I can see, here are the pros and cons: Pro (For blog posts):
1. More than 200 blog posts (potentially 1000+ words each with dozens of photos and potentially a video)..
2. More pages to crawl, index and rank..
3. More pages to post on social media..
4. Able to comment about the posts in the newsletter - Sounds more unique than "We've just updated this product page"..
5. Commenting is available on blog posts, whereas it is not on product pages..
6. So much information could slow down the loading of product pages significantly..
7. Some products are very similar (ie, the same product but "better quality" - Difficult to explain without giving the niche away, which i'd prefer not to do ATM) and this would mean the same content isn't on multiple pages.
8. By my understanding, this would be better for Google Authorship/Publishership.. Con (Against blog posts. For extended product pages):
1. Customers have all information in one place and don't have to click on a "Related Blog posts" tab..
2. More content means better ability to rank for product related keywords (All but a few receive very few searches per month, but the niche is exploding at an amazing rate at the moment)..
3. Very little chance of a blog post out-ranking the related product page for keywords.. I've run out of ideas for the 'Con' side of things, but that's why I'd like opinions from someone here if possible. I'd really appreciate any and all input, Thanks! [EDIT]:
I should add that there will be a small "How to make" style section on product pages anyway, which covers the most common step by step instructions. In the content we planned for blog posts, we'd explore the regular method in greater detail and several other methods in good detail. Our products can be "made" in several different ways which each result in a unique end result (some people may prefer it one way than another, so we want to cover every possible method), effectively meaning that there's an almost unlimited amount of content we could write.
In fact, you could probably think of the blog posts as more of "an ultimate guide to X" instead of simply "How to X"...0 -
How to Define Best URL Structure for Product Pages?
I am working on my website to edit structure with help of Google's search engine optimization starter guide. There is really good instruction to define URL structure which help us to perform well over Google's organic search. I have resolved issues regarding category pages but, I have confusion to define best URL structure for product pages. My website's product page URL structure is as follow. http://www.vistastores.com/marketumbrellas-californiaumbrella-slpt758-f13-red.html http://www.vistastores.com/homefurniture-winsomewood-93630.html URL structure is constructed with following terms. 1. Root Category Name (Market Umbrellas or Home Furniture or ....) 2. Brand Name 3. Manufacturer Part Number I am not happy with this structure and also not performing well over Google's organic search. I am thinking to include product name or title tag in URL after root domain. But, it may create very long URL and create issues in organic search display. Does it really matter to perform well over Google's organic search? How can I define best URL structure for product pages?
