      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

            Product Colour Variation and Canonicals

            Hi there, We are currently doing an SEO audit of an ecommerce website and we ar eunsure on the best practice in terms of using canonical link tag for some product variations. An example is that the company has a product with two colour variations: Black and Tan. These are for the same product and have 99% the same content. Within the content of the page the colour is the only thing that changes (along with the meta information and imagery of course). My question is should we choose one product and canonically link back to that one i.e. Black is the main product and we link Tan back to this via a canonical link? Many thanks in advance.

            SVG image files causing multiple title tags on page - SEO issue?

            Does anyone have any experience with SVG image files and on-page SEO? A client is using them and it seems they use the title tag in the same way a regular image (JPG/PNG) would use an image ALT tag. I'm concerned that search engines will see the multiple title tags on the page and that this will cause SEO issues. Regular crawlers like Moz flag it as a second title tag, however it's outside the header and in a SVG wrap so the crawlers really should understand that this is a SVG title rather than a second page title. But is this the case? If anyone has experience with this, I'd love to hear about it.

            How will it effect SEO to have multiple h1 tags on a page?

            I have a client who recieved this advice from his marketing consultant: "If there are multiple h1 tags on a page, this can confuse Google and it may have a negative impact on the keyword rankings. If you could ask your web developer to go in and remove the h1 tags on the header images that would be helpful. This way it will be easier for Google to index your site and will help your keyword rankings." How will it effect SEO to have multiple h1 tags on a page?

            Selling Products with a similar meta description

            Wondering if anyone can help when selling similar products with very similar meta description and product descriptions in general. Have around 500 products - a lot of products have around 10-20 products which are very similar only different is sizes and a maybe a few lines of text if that. Is this a problem in search engines? How does other ecommerce stores selling similar products solve this problem...

            Pagination for product page reviews

            Hi, I am looking to add pagination on product pages (they have lots of reviews on the page). I am considering using rel="next/prev, to connect the series of review pages to the main product page. I unfortunately don't have a view-all page for these reviews or the option to get one - the reviews refresh on the same product page (by clicking whatever number page of reviews). This means each page has the exact same description content and everything else, but with different reviews. In this case is rel=next a good option? The format currently would be: On example.com/product link rel="next" href="http://example.com/product?review-p2" On example.com/product?review-p2 link rel="prev" href="http://example.com/product, link rel="next" href="http://example.com/product?review-p3 etc. Would this be a good format for product page reviews? I see rel=nextprev commonly used on ecommerce category/list pages but not really on the paginated reviews on product pages, so I thought I would see if anyone has advice on how best to solve this. I'm also wondering if it would be best to not combine this with a canonical tag on all the different review pages pointing to the product page, seeing as the reviews are actually different (despite the rest of the content being identical). I am hoping to pick up longer tail traffic from this, I figure by connecting the pages and not using canonicals that this way I could get more traffic from the phrases used in the reviews. By leaving out the canonicals, is it possible a user searching for phrases that might be deeper in the series, to land on, say, ?review-p4? Any thoughts if this would drive more traffic? Thanks!.

            Multiple Cities in Title Tag

            My question is how to avoid having a spammy title. Currently I'm working on a project where a business serves four cities, but two of them are out of its home state. I'm trying to create a title tag that is appealing to the eyes, and meets what I need it to do at the same time. I was wondering what everyone though of this sample Brand X Dealer Serving Newark, DE; New Castle, DE; Glens Mills, PA; and Springfield, PA I know that too much repetition can be a bad thing, but this might not be a big deal since they are separate instances. Let me know what you all think. Thanks!

            Multiple domains vs single domain vs subdomains ?

            I have a client that recently read an article that advised him to break up his website into various URL's that targeted specific products. It was supposed to be a solution to gain footing in an already competitive industry. So rather than company.com with various pages targeting his products, he'd end up having multiple smaller sites: companyClothing.com companyShoes.com Etc. The article stated that by structuring your website this way, you were more likely to gain ranking in Google by targeting these niche markets. I wanted to know if this article was based on any facts. Are there any benefits to creating a new website that targets a specific niche market versus as a section of pages on a main website? I then began looking into structuring each of these product areas into subdomains, but the data out there is not definitive as to how subdomains are viewed by Google and other search engines - more specifically how subdomains benefit (or not!) the primary domain. So, in general, when a business targets many products and services that cover a wide range - what is the best way to structure the delivery of this info: multiple domains, single domain with folders/categories, or subdomains?  If single domain with folders/categories are not an option, how do subdomains stack up? Thanks in advance for your help/suggestions!
