Indexing of internal search results: canonicalization or noindex?
-
Hi Mozzers,
First time poster here, enjoying the site and the tools very much.
I'm doing SEO for a fairly big ecommerce brand and an issue regarding internal search results has come up.
www.example.com/electronics/iphone/5s/ gives an overview of the the model-specific listings. For certain models there are also color listings, but these are not incorporated in the URL structure.
Here's what Rand has to say in Inbound Marketing & SEO: Insights From The Moz Blog
Search filters are used to narrow an internal search—it could be price, color, features, etc.
Filters are very common on e-commerce sites that sell a wide variety of products. Search filter
URLs look a lot like search sorts, in many cases:
www.example.com/search.php?category=laptop
www.example.com/search.php?category=laptop?price=1000
The solution here is similar to the preceding one—don’t index the filters. As long as Google
has a clear path to products, indexing every variant usually causes more harm than good.I believe using a noindex tag is meant here.
Let's say you want to point users to an overview of listings for black 5s iphones. The URL is an internal search filter which looks as follows:
www.example.com/electronics/apple/iphone/5s?search=black
Which you wish to link with the anchor text "black iphone 5s".
Correct me if I'm wrong, but if you no-index the black 5s search filters, you lose the equity passed through the link. Whereas if you canonicalize /electronics/apple/iphone/5s you would still leverage the link juice and help you rank for "black iphone 5s". Doesn't it then make more sense to use canonicalization?
-
Hi there,
Just to round this question off, you could canonicalise the query-string URL searching for black iPhones to the iPhone 5s listings page and keep an individual phone's lising at /123456 separate, yes. It's best to keep the canonical tag for truly duplicated or near-duplicated pages, so you would not want to canonicalise an individual product page to a listings page or similar.
-
The tag is good for duplicate content but if /123456 has unique content then you probably don't need the tag on it. I would refrain from trying to implement the tag on ? on larger terms as it will give you a headache.
Some handy tips here- http://moz.com/learn/seo/canonicalization
In Short -
Set up the tag on the filters e.g a page that's the same content but its showing the colour blue then it will feed back the juice to the original but if you've got a page that's not duplicate and has content on it then you could leave it be. Google's pretty clever at working out relationships on pages and duplicate content is not the worse problem for SEO.
Hope that helps!

I meant to say that /123456 is an individual listing and /5gs gives an overview of all listings.
Then I could include a canonical tag at /5gs?search=black pointing to /5gs and NOT include a canonical tag at /5gs/123456 because I want the individual listing to rank?
-
Assuming the info is the same content (duplicate) just with a colour etc.
www.example.com/electronics/apple/iphone/5gs/123456
I would put the tag on that page pointing towards:
www.example.com/electronics/apple/iphone/5gs
What the tag is doing is saying the page (123456) is a duplicate of the another page, here is the other page (the link in tag) then Google will put all relevant juice to the original.
The canonical tag is great for duplicate content but it by putting it on a page deeper in the structure it only affects that page not any others. You can sometimes get a bit ahead by trying to canonical pages that don't exists like www.exsample.com?yay
-
Thanks!
I have a follow up question :).
What if there are listings with unique IDs with the following URL structure:
www.example.com/electronics/apple/iphone/5gs/123456
Then, canonicalizing /electronics/apple/iphone/5gs would prevent the listing from ranking.
What is best practice in these cases? Ideally I would like to pass link juice from the ?search filters to the canonical URL but leave the sub-directories as is.
-
Hi there,
Looks like you've gotten to the bottom of it there. The canonical tag is best as you wouldn't loose any link juice but it would get the desired effect of not indexing the filter.
Looks like you've got a handle on it so good luck!

Short description about our search results drop + forum moving to subdomain question.
Hello, here is our story. Our niche is mental health (psychology, psychotherapy e.t.c). Our portal has thousand of genuine articles, news section about mental health, researches, job findings for specialists, a specialized bookstore only with psychology books, the best forum in country, we thousands of active members and selfhelp topics etc. In our country (non english), our portal has been established in 2003. Since then, for more than 15 years, we were no 1 in our country, meaning that we had the best brand name, hundreds of external authors writing unique content for our portal and hundreds of no1 keywords in google search results. Actually, we had according to webmaster tools, more than 1.000 keywords, in 1 and 2 position. (we were ranking no1 in all the best keywords). Before 2 years, we purchased the best domain in our niche. I ll use the below example (of course, domains are not the real ones):
Intermediate & Advanced SEO | | dodoni
We had: e-pizza.com and now we have: pizza.com
We did the appropriate redirects but from day one, we had around 20-30% drop in search engines. After 6 months -which is something that google officialy mentions, we lost all "credits from the old domain.. .and at that point, we had another 20-30% drop in search results. Further more, in any google core update, we were keep dropping. Especially in last May (coronovirus update), we had another huge drop. We do follow seo guides, we have a dedicated server, good load speed, well structured data, amp, a great presence in social media, with more than 130.000 followers, etc. According to our investigation, we came to one only conclusion: that our forum, kills our seo (of course, noone in our team can guarantee that this is the actual reason of the uge drop in may-in coronovirus google core update). We believe that the forum kills our seo, because it produces low quality posts by members. For example, psychopharmacology in a very active sections and we believe, google is very "sensitive" in these kind of posts and information. So here is the question: although the forum is very very active, with thousands of new topics and posts every month, we are thinking of moving it to a subdomain, from the subfolder that now is.
This will help our domain authority to increase from 38 that is stuck 2 years now, to larger scales. We believe that althougth this forum gave a great boost to the portal, in the past 10-15 years, it somehow makes a negative impact now. If I could give more spesific details, I d say this: in all seo tools we run, the best kewwords bringing visitors to us, arent anymore, psychology and psychotherapy and mental health and this kind of top-keywords, but are mostly the ones from the forum, like: I want to proceed with a suicide, I m taking efexor or xanax and they have side effects, why i gain wieght with the antidepressants I get etc. 1. Moving our forum to subdomain, will be some kind of pain, since it is a large community, with thousands of backlinks that we somehow must handle in a proper way, also with a mobile application, things that will have to change and probably have some kind of negative impact. Would that be according to your knowledge a correct move and our E-A-T will benefit for google, or since google will know that the subdomain is still part of the same website/portal, it will handle it somehow, the same way as it does now? I have read hundreds of articles about forum in subdomains or in subfolders, but none of them covers a case stydy like ours, since most articles are talking about new forums and what is the best way to handle them and where is the best place to create them (in subfolder of subdomain) when from scratch. Looking forward to your answers.0 -

URL Spoof Issue in Search Results
Hello! We could use some assistance diagnosing an issue. In order to avoid asking a convoluted question, I will try to break it down below: 1. A random foreign site is hacked and a subdirectory is added that is completely irrelevant to the root. a). i.e. http://www.um.org/prom_dresses/ 2. http://www.um.org/prom_dresses/ is just a phishing prom dress page 3. When you search "prom dress shop", the website that used to rank first (for good reason) was www.promdressshop.com. 4. www.promdressshop.com's home page has now been replaced by: um.org/prom_dresses/ – who is using prom dress shop's title tag and meta description. How is it possible that this hacked page (on um.org) is not only ranking above us, but is also starting to replace www.promdressshop.com's pages in search results. We do not believe www.promdressshop.com has been hacked but are open to any ideas. Please let me know if you would like any additional info. Thanks in advance! new

"No Index, No Follow" or No Index, Follow" for URLs with Thin Content?
Greetings MOZ community: If I have a site with about 200 thin content pages that I want Google to remove from their index, should I set them to "No Index, No Follow" or to "No Index, Follow"? My SEO firm has advised me to set them to "No Index, Follow" but on a recent MOZ help forum post someone suggested "No Index, No Follow". The MOZ poster said that telling Google the content was should not be indexed but the links should be followed was inconstant and could get me into trouble. This make a lot of sense. What is proper form? As background, I think I have recently been hit with a Panda 4.0 penalty for thin content. I have several hundred URLs with less than 50 words and want them de-indexed. My site is a commercial real estate site and the listings apparently have too little content. Thanks, Alan

Website not being indexed after relocation
I have a scenario where a 'draft' website was built using Google Sites, and published using a Google Sites sub domain. Consequently, the 'same' website was rebuilt and published on its own domain. So effectively there were two sites, both more or less identical, with identical content. The first website was thoroughly indexed by Google. The second website has not been indexed at all - I am assuming for the obvious reasons ie. that Google is viewing it as an obvious rip-off of the first site / duplicate content etc. I was reluctant to take down the first website until I had found an effective way to resolve this issue long-term => ensuring that in future Google would index the second 'proper' site. A permanent 301 redirect was put forward as a solution - however, believe it or not, the Google Sites platform has no facility for implementing this. For lack of an alternative solution I have gone ahead and taken down the first site. I understand that this may take some time to drop out of Google's index, however, and I am merely hoping that eventually the second site will be picked up in the index. I would sincerely appreciate an advice or recommendations on the best course of action - if any! - I can take from here. Many thanks! Matt.

Reducing Booking Engine Indexation
Hi Mozzers, I am working on a site with a very useful room booking engine. Helpful as it may be, all the variations (2 bedrooms, 3 bedrooms, room with a view, etc, etc,) are indexed by Google. Section 13 on Search Pagination in Dr. Pete's great post on Panda http://www.seomoz.org/blog/duplicate-content-in-a-post-panda-world speaks to our issue, but I was wondering since 2 (!) years have gone by, if there are any additional solutions y'all might recommend. We want to cut down on the duplicate titles and content and get the useful but not useful for SERPs online booking pages out of the index. Any thoughts? Thanks for your help.
