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.

Proper Title Tags for ecommerce
In terms of E-commerce title tags. We are a manufacturer of our own clothing products. We are new to the SEO landscape so if this question is an obvious answer, then i apologize for wasting any one times in advance. We Manufacture our own clothing. Each item has a name. The names are American womens names such as amanda or lori or jenniffer etc. When we create the title tag for them should we include the name of the item itself at the beginning or end. For example should it be Item Name - Keyword - Keyword - Brand Name(aka manufacturer) or Keyword - Keyword - Item Name - Brand Name (aka manufacturer) The reason we ask this is because we think it would be a waste to rank for actual American names such as Jennifer and Jessica. All that we have read on Moz suggests that it seems to be better to have pertinent keywords in the beginning of the title as opposed to the end. In terms of our brand name we already rank number 1 for every combination of our brand. So we would like to start picking up traffic for the different product types we sell and there respective synonyms. Not sure if i am making any sense. Sorry in advance, and any help is very very much appreciated.

Adding hreflang tags - better on each page, or the site map?
Hello, I am wondering if there seems to be a preference for adding hreflang tags (from this article). My client just changed their site from gTLDs to ccTLDs, and a few sites have taken a pretty big traffic hit. One issue is definitely the amount of redirects to the page, but I am also going to work with the developer to add hreflang tags. My question is - is it better to add them to the header of each page, or the site map, or both, or something else? Any other thoughts are appreciated. Our Australia site, which was at least findable using Australia Google before this relaunch, is not showing up, even when you search the company name directly. Thanks!Lauryn

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.

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

E-commerce site, one product multiple categories best practice
Hi there, We have an e-commerce shopping site with over 8000 products and over 100 categories. Some sub categories belong to multiple categories - for example, A Christmas trees can be under "Gardening > Plants > Trees" and under "Gifts > Holidays > Christmas > Trees" The product itself (example: Scandinavian Xmas Tree) can naturally belong to both these categories as well. Naturally these two (or more) categories have different breadcrumbs, different navigation bars, etc. From an SEO point of view, to avoid duplicate content issues, I see the following options: Use the same URL and change the content of the page (breadcrumbs and menus) based on the referral path. Kind of cloaking. Use the same URL and display only one "main" version of breadcrumbs and menus. Possibly add the other "not main" categories as links to the category / product page. Use a different URL based on where we came from and do nothing (will create essentially the same content on different urls except breadcrumbs and menus - there's a possibiliy to change the category text and page title as well) Use a different URL based on where we came from with different menus and breadcrumbs and use rel=canonical that points to the "main" category / product pages This is a very interesting issue and I would love to hear what you guys think as we are finalizing plans for a new website and would like to get the most out of it. Thank you all!

Duplicate content on ecommerce sites
I just want to confirm something about duplicate content. On an eCommerce site, if the meta-titles, meta-descriptions and product descriptions are all unique, yet a big chunk at the bottom (featuring "why buy with us" etc) is copied across all product pages, would each page be penalised, or not indexed, for duplicate content? Does the whole page need to be a duplicate to be worried about this, or would this large chunk of text, bigger than the product description, have an effect on the page. If this would be a problem, what are some ways around it? Because the content is quite powerful, and is relavent to all products... Cheers,

How To Best Close An eCommerce Site?
We're closing down one of our eCommerce sites. What is the best approach to do this? The site has a modest link profile (a young site). It does have a run of site link to the parent site. It also has a couple hundred email subscribers and established accounts. Is there a gradual way to do this? How do I treat the subscribers and account holders? The impact won't be great, but I want to minimize collateral damage as much as possible. Thanks.

Canonical Tag and Affiliate Links
Hi! I am not very familiar with the canonical tag. The thing is that we are getting traffic and links from affiliates. The affiliates links add something like this to the code of our URL: www.mydomain.com/category/product-page?afl=XXXXXX At this moment we have almost 2,000 pages indexed with that code at the end of the URL. So they are all duplicated. My other concern is that I don't know if those affilate links are giving us some link juice or not. I mean, if an original product page has 30 links and the affiliates copies have 15 more... are all those links being counted together by Google? Or are we losing all the juice from the affiliates? Can I fix all this with the canonical tag? Thanks!
