Best way to implement canonical tags on an ecommerce site with many filter options?
-
What would be the best way to add canonical tags to an ecommerce site with many filter options, for example, http://teacherexpress.scholastic.com?
Should I include a canonical tag for all filter options under a category even though the pages don't have the same content?
Thanks for reading!

This is generally an exception Google supports - for example, they say that you can use rel=prev/next and rel=canonical in conjunction, where one handles pagination and the other handles sorts/filters. In the case of a sort (like ascending/descending) the actual results could be very different, but the intent is still legitimate. They generally understand you're trying to clean up these pages.
In a perfect world, these filters wouldn't create unique URLs, honestly, but now that they already exist, you have to manage them. The other option would just be to META NOINDEX those filter URLs or set them up in parameter handling in Google Webmaster Tools. I tend to prefer the canonical here, personally.

Thank you very much Federico!
I saw a couple of articles warning against canonicalizing if the content isn't extremely similar. Can you help me understand how this doesn't apply?
e.g. Searchenginewatch: "The most common misuse of the tag is when it's implemented on pages that don't include a large percentage of the same content as the canonical page. Unless they contain considerable chunk of duplicate content, rel="canonical" probably shouldn't be used."
Google:
Must the content on a set of pages be similar to the content on the canonical version?
Yes. The
rel="canonical"attribute should be used only to specify the preferred version of many pages with identical content (although minor differences, such as sort order, are okay).For instance, if a site has a set of pages for the same model of dance shoe, each varying only by the color of the shoe pictured, it may make sense to set the page highlighting the most popular color as the canonical version so that Google may be more likely to show that page in search results. However,
rel="canonical"would not be appropriate if that same site simply wanted a gel insole page to rank higher than the shoe page. -
Hey Daniel,
The canonical should point on every possible filtering to the main page without any filter.

Hope that helps.

Schema markup concerning category pages on an ecommerce site
We are adding json+ld data to an ecommerce site and myself and one of the other people working on the site are having a minor disagreement on things. What it comes down to is how to mark up the category page. One of us says it needs to be marked up with as an Itempage, https://schema.org/ItemPage The other says it needs to be marked up as products, with multiple product instances in the schema, https://schema.org/Product The main sticking point on the Itemlist is that Itemlist is a child of intangible, so there is a feeling that should be used for things like track listings or other arbitrary data.

Ecommerce Site - Duplicate product descriptions & SKU pages
Hi I have a couple of questions regarding the best way to optimise SKU pages on a large ecommerce site. At the moment we have 2 landing pages per product - one is the primary landing page with no SKU, the other includes the SKU in the URL so our sales people & customers can find it when using the search facility on the site. The SKU landing page has a canonical pointing to the primary page as they're duplicates. Is this the best way? Or is it better to have the one page with the SKU in the URL? Also, we have loads of products with the very similar product descriptions, I am working on trying to include a unique paragraph or few sentences on these to improve the content - how dangerous is the duplicate content within your own site? I know its best to have totally unique content, but it won't be possible on a site with thousands of products and a small team. At the moment I am trying to prioritise the products to update. Thank you 🙂

Ecommerce Site homepage , Is it okay to have Links as H2 Tags as that is relevant to the page ?
Hi All, I have a Rental site and I am bit confused with how best do my H Tags on my homepage I know the H1 is the most important, Then H2 Tags and so on.. and that these tags should really be titles for content. However, I have a few categories (links) on my homepage so I am wondering if I could put these as H2 Tags given that it is relevant to the page . H3 Tags will my News and Guides etc , H4 Tags will the whats on the footer. I am attached a made up screenshot of what I propose for my homepage if someone could please give it a quick look , it would be very much appreciated. I have looked at what some competitors do a lot of them don't seem to have h2's etc but I know it's an important factor for rankings etc. Many thanks Pete dJSFQwI

Problems with ecommerce filters causing duplicate content.
We have an ecommerce website with 700 pages. Due to the implementation of filters, we are seeing upto 11,000 pages being indexed where the filter tag is apphended to the URL. This is causing duplicate content issues across the site. We tried adding "nofollow" to all the filters, we have also tried adding canonical tags, which it seems are being ignored. So how can we fix this? We are now toying with 2 other ideas to fix this issue; adding "no index" to all filtered pages making the filters uncrawble using javascript Has anyone else encountered this issue? If so what did you do to combat this and was it successful?

Are pages with a canonical tag indexed?
Hello here, here are my questions for you related to the canonical tag: 1. If I put online a new webpage with a canonical tag pointing to a different page, will this new page be indexed by Google and will I be able to find it in the index? 2. If instead I apply the canonical tag to a page already in the index, will this page be removed from the index? Thank you in advance for any insights! Fabrizio

Best approach to launch a new site with new urls - same domain
www.sierratradingpost.com We have a high volume e-commerce website with over 15K items, an average of 150K visits per day and 12.6 pages per visit. We are launching a new website this spring which is currently on a beta sub domain and we are looking for the best strategy that preserves our current search rankings while throttling traffic (possibly 25% per week) to measure results. The new site will be soft launched as we plan to slowly migrate traffic to it via a load balancer. This way we can monitor performance of the new site while still having the old site as a backup. Only when we are fully comfortable with the new site will we submit the 301 redirects and migrate everyone over to the new site. We will have a month or so of running both sites. Except for the homepage the URL structure for the new site is different than the old site. What is our best strategy so we don’t lose ranking on the old site and start earning ranking on the new site, while avoiding duplicate content and cloaking issues? Here is what we got back from a Google post which may highlight our concerns better: http://www.google.com/support/forum/p/Webmasters/thread?tid=62d0a16c4702a17d&hl=en&fid=62d0a16c4702a17d00049b67b51500a6 Thank You, sincerely, Stephan Woo Cude SEO Specialist [email protected]
