      I'm building an eCommerce website which has an advanced filter on the left hand side of the category pages.

      It allows users to tick boxes for colours, sizes, materials, and so on. When they've made their choices they submit (this will likely be an AJAX thing in a future release, but isn't at time of writing).

      The new filtered page has a new URL, which is made up of the IDs of the filter's they've ticked - it's a bit like /department/2/17-7-4/10/

      My concern is that the filtered pages are, on the most part, going to be the same as the parent. Which may lead to duplicate content.

      My other concern is that these two URLs would lead to the exact same page (although the system would never generate the 'wrong' URL)

      • /department/2/17-7-4/10/
      • /department/2/**10/**17-7-4/

      But I can't think of a way of canonicalising that automatically.

      Tricky.

      So the meat of the question is this: should I worry about this causing issues with the SEO - or can I have trust in Google to work it out?

        Andie -

        We work on a lot of eCommerce sites with similar left-hand navigation filters.

        I think that the thing to keep in mind is that these pages are often like search results pages, and require a human to choose options to create those URLs.  As a result, they shouldn't be pages that a typical crawl bot would find.

        That said, each eCommerce system acts differently, and it's possible that permanent links are created that are added to a site map. Or, it's possible that Google's bots are starting to check boxes on eCommerce filters to better mimic human behavior.  After all, Google has created self-driving cars.

        The data driven approach: I would check to see if any of these pages are showing up in Google Webmaster tools to see if it is, indeed, an issue, before trying to go crazy about duplicate content.

        Hope this helps,
        -- Jeff

          On-page SEO

          onpage

          This is a question for the organic SEO experts, once you added the main keyword that you want to rank for in the homepage title, meta title plus meta description, perhaps once or twice in the text on the homepage. How often do you then write it in the content marketing, say blog posts, we want to rank higher on Google for "SEO agencies Cardiff" however if you mention this in the blog posts too much say once a week, this could lead to over optimisation issues?

          Schema Markup for eCommerce Category Pages?

          My research indicates that applying an ItemList schema markup to our category pages is likely the best way to go. However, I've also ready that Google discourages schema markup on category pages. I'm just wondering if any of you have applied schema markup to your category pages and, if so, how did you do it?

          Affect of ™ and ® in title for SEO

          I am looking at adding the trademark and rights reserved symbols to some of my titles. I think this might help with click through rate. From what I have found, this shouldn't have an affect on SEO unless it makes the title too long. Is this correct? Stephen

          Phone number for SEO

          We have had an interesting question from a client. They have asked if removing their phone number from their website would have an affect on their rankings. Our immediate answer was 'No' but it may affect the Brand, Usability and Customer experience by restricting the methods of contact. This then made us think that perhaps then it could have an effect in the long term. This situation is also complicated by the fact that they do not have a Google Local Plus account for operational, sensitivity reasons (they don't want to openly publicise their address) We believe that there shouldn't be any negative affect but thought we would open a discussion. Thanks in advance for any comments/ideas.

          HTML Site SEO (NO CMS)

          I have got a client site, which is dated (2007) and has not been shifted to any recognised CMS yet. It is HTML based. Is it possible to SEO on such a site? Is it even worth it? If it is possible to do SEO on this, any suggestions will be highly appreciated. Thank you.

          Analyzing word count on page SEO

          Hey guys quick question, when I am analyzing/ doing word count for a particluar key word and I want to make sure that i am no where near Keyword stuffing, does Google consider the alt and title tags keywords of images as part of the KW count when looking for on page Keyword stuffing. For example. let say I have a page that i just created with 1000 words. and Only 2 of the words are my target Keywords. Then, if i add a picture and add the keyword to both the alt and title tag and description of the image, does google now consider the "page" to have a total of 5 keywords? Also, a lot has changed recently since penguin and panda, is there a good rule of thumb for what ratio to stay under as far as keywords to text.?
