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.

"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!

Use webmaster tools "change of address" when doing rel=canonical
We are doing a "soft migration" of a website. (Actually it is a merger of two websites). We are doing cross site rel=canonical tags instead of 301's for the first 60-90 days. These have been done on a page by page basis for an entire site. Google states that a "change of address" should be done in webmaster tools for a site migration with 301's. Should this also be done when we are doing this soft move?

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 🙂

Should we use "and" or "&"?
Our client has an ampersand in their brand name. The logo has "&", their url is spelled out. I'm trying to get them to standardize the use of the name for directories/listings. Should we use "and" or "&"?
