Should my canonical tags point to the category page or the filter result page?
-
Hi Moz,
I'm working on an ecommerce site with categories, filter options, and sort options – teacherexpress.scholastic.com.
Should I have canonical tags from all filter and sort options point to the category page like gap.com and llbean.com? or have all sort options point to the filtered page URL like kohls.com?
I was under the impression that to use a canonical tag, the pages have to have the same content, meaning that Gap and L.L. Bean would be using canonical tags incorrectly. Using a filter changes the content, whereas using a sort option just changes the order.
What would be the best way to deal with duplicate content for this site?
Thanks for reading!

Hi Daniel,
You've gotten some good responses to your question. Do you have any additional questions or comments you would like to add?

I agree, that's a great approach. I think you mean Javascript, not Java though (that's a different language). The only thing that might make this approach a challenge would be if you had so much product data before filtering that it caused a performance problem, i.e. let's say you had 50 pages of results...if you filter server-side, you're only sending down 1 page of results, whereas if you're filtering with client-side Javascript, you've got to send all 50 pages down and then filter it in the browser.

Hi Daniel,
Another option may be use java on your filter page so that however customers filter the product, the URL will remain the same with extra parameters in the URL to filter out the products. I find this the best way as you have the same URL for all sort of customization/filter and able to avoid duplicate content.
For example: Macys

Hi Daniel,
You're going to have to walk a fine line between having a page for every possible combination of filtered results that a user might search for AND appearing to have a ton of pages that are really almost identical....and suffering the wrath of Panda upon seeing what it thinks is duplicate content.
The easy way out is to have 1 page for each category, and no matter what filters are applied, rel=canonical to that category. Dupe content problem solved.
So why isn't this the ideal solution?
#1 You may be missing out on targeting combinations of categories and filters that users will commonly search for. Let's say you were selling clothing, and a category was shirts, and you had a filter for men/women/boys/girls. By making all shirts list pages rel=canonical to the overall shirts list page (with no filters), you'd be missing an opportunity to target "boys shirts".
#2 You may be missing opportunities to pour more link juice to the individual product pages. It's unclear (to me, anyway) whether Google adds the link juice from all pages rel=canonical'ed to a page, or whether Google simply treats rel=canonical as "oh ya, I've already seen & dealt with this page". Certainly in my testing I've seen places where pages rel=canonical'ed to another page actually still show up in the search results, so I'd say rel=canonical isn't as solid as a 301.
So what do you do? I'd recommend a mix. Figure out what combinations you think you can get search traffic from, and find a way to break down the complete set of combinations of filters and categories to target those, and to rel=canonical every page to one of your targeted pages.
It's entirely possible (likely, even) that you'll end up with a mix. For instance, going back to my earlier example, let's say you had another filter that was, let's say, price range. You might want to target "boys shirts", but not "boys shirts under $20". So, while "boys" was a filter value, and "under $20" was a filter value, you might rel=canonical all pages in the category "boys" with a filter value of "shirts" to your page that has just that category and that 1 filter set, regardless of setting of the price filter.
Clear as monkey poop?

Log-in page ranking instead of homepage due to high traffic on login page! How to avoid?
Hi all, Our log-in page is ranking in SERP instead of homepage and some times both pages rank for the primary keyword we targeted. We have even dropped. I am looking for a solution for this. Three points here to consider is: Our log-in page is the most visited page and landing page on the website. Even there is the primary keyword in this page or not; same scenario continues Log-in page is the first link bots touch when they crawling any page of our website as log-in page is linked on top navigation menu If we move login page to sub-domain, will it works? I am worrying that we loose so much traffic to our website which will be taken away from log-in page sub domain Please guide with your valuable suggestions. Thanks

E.g. www.website.com/page/#keyword-anchor-text Where the part after the # is a section of the page you can jump to, and the title of that section is a secondary keyword you want the page to rank for?

If my article is reposted on another blog, using re=canonical, does that count as a link back?
Hey all! My company blog is interested in letting another blog repost our article. We would ask them to use "re-canonical" in the mark-up to avoid Google digging through "duplicate" info out there. I was wondering, if the other site does use the "re=canonical", will that appear as a backlink or no? I understand that metrics will flow back to my original URL and not the canonical one, but I am wondering if the repost will additionally show as a backlink. Thanks!

Does google index non-public pages ie. members logged in page
hi, I was trying to locate resources on the topics regarding how much the google bot indexes in order to qualify a 'good' site on their engine. For example, our site has many pages that are associated with logged in users and not available to the public until they acquire a login username and password. Although those pages show up in google analytics, they should not be made public in the google index which is what happens. In light of Google trying to qualify a site according to how 'engaged' a user is on the site, I would feel that the activities on those member pages are very important. Can anyone offer suggestions on how Google treats those pages since we are planning to do further SEO optimization of those pages. Thanks

Title tag consistency. Is it worth it?
I operate a stain removal website and was wondering how consistent it was worth being from title tag to title tag. To give you an example, here is a group of keyword phrases that I might wish to target: "getting out pet stains with vinegar" "how do I remove water stains from wood" "removing chocolate stains" Does the benefit to be gained (whatever that might be) from making these consistently of the form "how to remove X from Y, " or "how to remove X" outweigh simply giving articles titles based on the exact phrases above? I heard from someone that Google is getting more proficient at spotting "clumsy" title tags, although I'm not sure if any of the above examples would fall into that category, and was thinking that I should then probably proceed on the basis of directly titling articles based on the exact keywords I am uncovering... Any advice much appreciated.

Using Brand Name in Page titles
Is it a good practice to append our brand name at the end of every page title? We have a very strong brand name but it is also long. Right now what we are doing is saying: Product Name | Long brand name here Product Category | Long brand name here Is this the right way to do it or should we just be going with ONLY the product and category names in our page titles? Right now we often exceed the 70 character recommendation limit.
