Quick Fix to "Duplicate page without canonical tag"?
-
When we pull up Google Search Console, in the Index Coverage section, under the category of Excluded, there is a sub-category called ‘Duplicate page without canonical tag’. The majority of the 665 pages in that section are from a test environment.
If we were to include in the robots.txt file, a wildcard to cover every URL that started with the particular root URL ("www.domain.com/host/"), could we eliminate the majority of these errors?
That solution is not one of the 5 or 6 recommended solutions that the Google Search Console Help section text suggests. It seems like a simple effective solution. Are we missing something?

No index & test Indexing Before You Launch
The domains are intended for development use and cannot be used for production. A custom or CMS-standard will only work
robots.txt on
Live environments with a custom domain. Adding sub-domains (i.e.,dev.example.com , ``test.example.com
) for DEV or TEST will remove the header only,X-Robots-Tag: noindex
but still, serve the domain.robots.txt
To support pre-launch SEO testing, we allow the following bots access to platform domains:
- Site Auditor by Raven
- SEMrush
- RogerBot by Moz
- Dotbot by Moz
If you’re testing links or SEO with other tools, you may request the addition of the tool to our
robots.txt
Pantheon's documentation on robots.txt: http://pantheon.io/docs/articles/sites/code/bots-and-indexing/User-agent: * Disallow: / User-agent: RavenCrawler User-agent: rogerbot User-agent: dotbot User-agent: SemrushBot User-agent: SemrushBot-SA Allow: /

The simplest solution would be to mark every page in your test environment "noindex". This is normally standard operating procedure anyway because most people don't want customers stumbling across the wrong URL in search by mistake and seeing a buggy page that isn't supposed to be "live" for customers.
Updating your robots.txt file would tell Google not to crawl the page, but if they've already crawled it and added it to their index it just means that they will retain the last crawled version of the page and will not crawl it in the future. You have to direct Google to "noindex" the pages. It will take some time as Google refreshes the crawl of each page, but eventually you'll see those errors drop off as Google removes those pages from their index. If I were consulting a client I would tell them to make the change and check back in two or three months.
Hope this helps!

The new version of search console will show all the pages available on your site. even the no-index pages, why? I don't know, the truth is even when you set up those pages as no-follow and no-index it will keeping show you the same error. That does not mean that there is something wrong with your site. I would not worry in your case.

How long does it take for canonical tags to work
How long on average does it take for a canonical tag to work? Understand that canonicals are just a suggestion, but after adding a canonical tag and submitting the page via Google fetch, assuming Google follows the canonical, would you expect it to work after a day or two or does it take longer? We added canonicals to old PPC landing pages that are ranking organically, though our new landing pages (which we want to rank organically) are not identical and have a bit more content/features. They are similar though. Canonicals were added to the old pages (pointing to new pages) and requested indexing via search console. Old pages are still ranking and new pages not so much. FYI we are unable to 301 old PPC pages due to other non negotiable reasons unfortunately. Thanks.

"Fourth-level" subdomains. Any negative impact compared with regular "third-level" subdomains?
Hey moz New client has a site that uses: subdomains ("third-level" stuff like location.business.com) and; "fourth-level" subdomains (location.parent.business.com) Are these fourth-level addresses at risk of being treated differently than the other subdomains? Screaming Frog, for example, doesn't return these fourth-level addresses when doing a crawl for business.com except in the External tab. But maybe I'm just configuring the crawls incorrectly. These addresses rank, but I'm worried that we're losing some link juice along the way. Any thoughts would be appreciated!

The Mysterious Case of Pagination, Canonical Tags
Hey guys, My head explodes when I think of this problem. So I will leave it to you guys to find a solution... My root domain (xxx.com) runs on WordPress platform. I use Yoast SEO plugin. The next page of root domain -- page/2/ -- has been canonicalized to the same page -- page/2/ points to page/2/ for example. The page/2/ and remaining pages also have this rel tags: I have also added "noindex,follow" to page/2/ and further -- Yoast does this automatically. Note: Yoast plugin also adds canonical to page/2/...page/3/ automatically. Same is the case with category pages and tag pages. Oh, and the author pages too -- they all have self-canonicalization, rel prev & rel next tags, and have been "noindex, followed." Problem: Am I doing this the way it should be done? I asked a Google Webmaster employee on rel next and prev tags, and this is what she said: "We do not recommend noindexing later pages, nor rel="canonical"izing everything to the first page." (My bad, last year I was canonicalizing pages to first page). One of the popular blog, a competitor, uses none of these tags. Yet they rank higher. Others following this format have been hit with every kind of Google algorithm I could think of. I want to leave it to Google to decide what's better, but then again, Yoast SEO plugin rules my blog -- okay, let's say I am a bad coder. Any help, suggestions, and thoughts are highly appreciated. 🙂 Update 1: Paginated pages -- including category pages and tag pages -- have unique snippets; no full-length posts. Thought I'd make that clear.

Geotargeting duplicate content to different regions - href and canonical tag confusion
If you duplicate content onto a sub-folder for say a new US geotargeted site (to target kw spelling differences) and, in addition to GWT geotargeting settings, implement the 'Canonical' and 'Hreflang' tags on these new pages to show G different region and language version (en-us). Then does the original/main site similar pages also need to have canonical and href tags ? The main/original sites page I don't really want to target a specific country (although existing signals (hosting etc) will be UK (primary target of main site) but pages show up in other country searches too (which we want). Im presuming fine to leave the original/main site as it currently is although wording in google blog/webmaster central articles etc are a bit confusing hence why im asking for anyone elses opinion/input on this. Also is there are any benefit (or just best practice) to use 'www.example.com/en-us/...' in the subdirectory URL as opposed to just 'www.example.com/us/' many thanks in advance to any commentators 🙂

Why "title missing or empty" when title tag exists?
Greetings! On Dec 1, 2011 in a SEOMoz campaign, two crawl metrics shot up from zero (Nov 17, Nov 24). "Title missing or empty" was 9,676. "Duplicate page content" was 9,678. Whoa! Content at site has not changed. I checked a sample of web pages and each seems to have a proper TITLE tag. Page content differs as well -- albeit we list electronic part numbers of hard-to-find parts, which look similar. I found a similar post http://www.seomoz.org/q/why-crawl-error-title-missing-or-empty-when-there-is-already-title-and-meta-desciption-in-place . In answer, Sha ran Screaming Frog crawler. I ran Frog crawler on a few hundred pages. Titles were found and hash codes were unique. Hmmm. Site with errors is http://electronics1.usbid.com Small sample of pages with errors: electronics1.usbid.com/catalog_10.html

Meta tag "noindex,nofollow" by accident
Hi, 3 weeks ago I wanted to release a new website (made in WordPress), so I neatly created 301 redirects for all files and folders of my old html website and transferred the WordPress site into the index folder. Job well done I thought, but after a few days, my site suddenly disappeared from google. I read in other Q&A's that this could happen so I waited a little longer till I finally saw today that there was a meta robots added on every page with "noindex, nofollow". For some reason, the WordPress setting "I want to forbid search engines, but allow normal visitors to my website" was selected, although I never even opened that section called "Privacy". So my question is, will this have a negative impact on my pagerank afterwards? Thanks, Sven
