Internal search : rel=canonical vs noindex vs robots.txt
-
Hi everyone,
I have a website with a lot of internal search results pages indexed. I'm not asking if they should be indexed or not, I know they should not according to Google's guidelines. And they make a bunch of duplicated pages so I want to solve this problem.
The thing is, if I noindex them, the site is gonna lose a non-negligible chunk of traffic : nearly 13% according to google analytics !!!
I thought of blocking them in robots.txt. This solution would not keep them out of the index. But the pages appearing in GG SERPS would then look empty (no title, no description), thus their CTR would plummet and I would lose a bit of traffic too...
The last idea I had was to use a rel=canonical tag pointing to the original search page (that is empty, without results), but it would probably have the same effect as noindexing them, wouldn't it ? (never tried so I'm not sure of this)
Of course I did some research on the subject, but each of my finding recommanded one of the 3 methods only ! One even recommanded noindex+robots.txt block which is stupid because the noindex would then be useless...
Is there somebody who can tell me which option is the best to keep this traffic ?
Thanks a million

Yeah, normally I'd say to NOINDEX those user-generated search URLs, but since they're collecting traffic, I'd have to side with Alan - a canonical may be your best bet here. Technically, they aren't "true" duplicates, but you don't want the 1K pages in the index, you don't want to lose the traffic (which NOINDEX would do), and you don't want to kill those pages for users (which a 301 would do).
Only thing I'd add is that, if some of these pages are generating most of the traffic (e.g. 10 pages = 90% of the traffic for these internal searches), you might want to make those permanent pages, like categories in your site architecture, and then 301 the custom URLs to those permanent pages.

Huh not sure since I'm not a developer (and didn't work on that website dev) but I'd say all of the above^^. If useful, here are their url structure, there's two kind :
- /searchpage.htm?action=search&pagenumber=xx&query=product+otherterms
So I guess they are generated when a user makes a search
paginated (about 15 pages generally),
and I can approximately know how much they are duplicates, I can tell some are probably overlapping when there's a lot of variations for the product. There are just a few complete duplicates (when the product searched is the same with different added terms, doesn't happen a lot in this list).
- /searchpage-searchterm-addedterm-number.htm
Those I find surprising, I don't know if they are pages generated with a fixed url, or if they are rewritten (Haven't looked at the htaccess yet, but I will, god I have a headache just thinking about reading that thing lol)
There's about a thousand of them all (from GGanalytics, about half of each sort, and nearly all are indexed by Google), on a website with about 12 thou total in pages.
Maybe the traffic loss will be compensated by the removed competition between those search pages and the product pages (and the rel=canonical is surely way less brutal than a noindex for that matter), but without experience in these kind of situations it's hard to make a decision...
Really appreciate you guys taking the time to help !

Alan's absolutely right about how canonical works, but I just want to clarify something - what about these pages is duplicated? In other words, are these regular searches (like product searches) with duplicate URLs, are these paginated searches (with page 2, 3, etc. that appear thin), or are these user-generated searches spinning out into new search pages (not exact duplicates but overlapping)? The solutions can vary a bit with the problem, and internal search is tricky.
-
Just one more point, a canonical is just a hint to the search engines, it is not a directive, so if they think that the pages should not be merged, they will ignore them, so in that way, they may make the decision for you
-
Not a lot of real duplicates, they're more alike, and the most visited are unique, so I'll keep the most important ones and just toss a few duplicates.
Thanks a lot for your help, problem solved !
-
no not like a noindex. more like a merge.
will it make you rank for many keywords? not necessarly, as a page all about blue widgets is going to rank higher then a page has many different subjects including blue widgets.
A canonical is really for duplicate content, or very alike content.
So you have to decide what your page is, is it duplicate or alike content, or is it unique?
if the pages are unique then do nothing, let them rank. if yopu think they are alike, then use a canonical. if there are only a few, then i would not worry either way.
if you decide they are unique, they I would look at making the page title unique also, maybe even description too.

Thanks for your answer
Ok you're saying indeed it will act like a noindex over time.
So if one of the result page would have ranked for a particular query, it will not rank any more, like with a noindex => it will lose the 13% of traffic it generated...
Otherwise it would be too easy to make a page rank for the keywords used in a bunch of other pages that refer to it via rel=canonical... wouldn't it ?
I'm starting to think I can't do anything... Maybe just noindex a bunch of them that cause duplicates, and leave the rest in the index.

Rel=canonical is tge way to go, it will tell the search results that all credit for all diffrent urls go to the original search page. eventual onl;y the original search page will exist in the index.

Crawl solutions for landing pages that don't contain a robots.txt file?
My site (www.nomader.com) is currently built on Instapage, which does not offer the ability to add a robots.txt file. I plan to migrate to a Shopify site in the coming months, but for now the Instapage site is my primary website. In the interim, would you suggest that I manually request a Google crawl through the search console tool? If so, how often? Any other suggestions for countering this Meta Noindex issue?

Discrepancy in actual indexed pages vs search console
Hi support, I checked my search console. It said that 8344 pages from www.printcious.com/au/sitemap.xml are indexed by google. however, if i search for site:www.printcious.com/au it only returned me 79 results. See http://imgur.com/a/FUOY2 https://www.google.com/search?num=100&safe=off&biw=1366&bih=638&q=site%3Awww.printcious.com%2Fau&oq=site%3Awww.printcious.com%2Fau&gs_l=serp.3...109843.110225.0.110430.4.4.0.0.0.0.102.275.1j2.3.0....0...1c.1.64.serp..1.0.0.htlbSGrS8p8 Could you please advise why there is discrepancy?

Do you need a canonical tag for search and filter pages?
Hi Moz Community, We've been implementing new canonical tags for our category pages but I have a question about pages that are found via search and our filtering options. Would we still need a canonical tag for pages that show up in search + a filter option if it only lists one page of items? Example below. www.uncommongoods.com/search.html/find/?q=dog&exclusive=1 Thanks!

Robots txt. in page with 301 redirect
We currently have a a series of help pages that we would like to disallow from our robots txt. The thing is that these help pages are located in our old website, which now has a 301 redirect to current site. Which is the proper way to go around? 1- Add the pages we want to disallow to the robots.txt of the new website? 2- Break the redirect momentarily and add the pages to the robots.txt of the old one? Thanks

Google insists robots.txt is blocking... but it isn't.
I recently launched a new website. During development, I'd enabled the option in WordPress to prevent search engines from indexing the site. When the site went public (over 24 hours ago), I cleared that option. At that point, I added a specific robots.txt file that only disallowed a couple directories of files. You can view the robots.txt at http://photogeardeals.com/robots.txt Google (via Webmaster tools) is insisting that my robots.txt file contains a "Disallow: /" on line 2 and that it's preventing Google from indexing the site and preventing me from submitting a sitemap. These errors are showing both in the sitemap section of Webmaster tools as well as the Blocked URLs section. Bing's webmaster tools are able to read the site and sitemap just fine. Any idea why Google insists I'm disallowing everything even after telling it to re-fetch?

I accidentally blocked Google with Robots.txt. What next?
Last week I uploaded my site and forgot to remove the robots.txt file with this text: User-agent: * Disallow: / I dropped from page 11 on my main keywords to past page 50. I caught it 2-3 days later and have now fixed it. I re-imported my site map with Webmaster Tools and I also did a Fetch as Google through Webmaster Tools. I tweeted out my URL to hopefully get Google to crawl it faster too. Webmaster Tools no longer says that the site is experiencing outages, but when I look at my blocked URLs it still says 249 are blocked. That's actually gone up since I made the fix. In the Google search results, it still no longer has my page title and the description still says "A description for this result is not available because of this site's robots.txt – learn more." How will this affect me long-term? When will I recover my rankings? Is there anything else I can do? Thanks for your input! www.decalsforthewall.com

Rel=Canonical, WWW vs non WWW and SEO
Okay so I'm a bit of a loss here. For what ever reason just about every single Wordpress site I has will turn www.mysite.com into mysite.com in the browser bar. I assume this is the rel=canonical tag at work, there are no 301s on my site. When I use the Open Site Explorer and type in www.mysite.com it shows a domain authority of around 40 and a few hundred backlinks... and then I get the message. Oh Hey! It looks like that URL redirects to XXXXXX. Would you like to see data for <a class="clickable redirects">that URL instead</a>? So if I click to see this data instead I have less than half of that domain authority and about 2 backlinks. *** Does this make a difference SEO wise? Should my non WWW be redirecting to my WWW instead because that's where the domain authority and backlinks are? Why am I getting two different domain authority and backlink counts if they are essentially the same? Or am I wrong and all that link juice and authority passes just the same?

Robots.txt Sitemap with Relative Path
Hi Everyone, In robots.txt, can the sitemap be indicated with a relative path? I'm trying to roll out a robots file to ~200 websites, and they all have the same relative path for a sitemap but each is hosted on its own domain. Basically I'm trying to avoid needing to create 200 different robots.txt files just to change the domain. If I do need to do that, though, is there an easier way than just trudging through it?
