Role of Robots.txt and Search Console parameters settings
-
Hi, wondering if anyone can point me to resources or explain the difference between these two. If a site has url parameters disallowed in Robots.txt is it redundant to edit settings in Search Console parameters to anything other than "Let Googlebot Decide"?
-
Thank you! That helps a lot.

So, regarding NOINDEX vs. DISALLOW, there is a significant difference there.
If you disallow in robots, you are asking the search engine to not even crawl that page. Whereas if you NOINDEX in the page head, then the search engine may still crawl the page but should not index it.
There are a few impacts of this difference. For one, if you use NOINDEX but still allow the search engine to FOLLOW, then it may discover pages which otherwise might not have been discovered (if that page has unique links, for example). So in this case, you might prefer to use (NOINDEX, FOLLOW) if you want that discovery to happen. On the other hand, if you have many pages and you are trying to wisely use the search engine's crawl "budget", then you might in some cases prefer to disallow some paths in the robots.txt file.
It's also common to use robots.txt to disallow some files where you do not have control over the response. Non-html files, where you might not be able to easily administer noindex directives. Or dynamic pages your web application may serve but not allow you to administer head tags for.
All of that said, robots.txt files have been shrinking ever since the search engines began to render javascript, since now they need access to a lot of resource files which they previously did not. Much of the old advice of disallowing scripts and admin folder paths may be obsolete now, if those files are needed to properly render pages.

Thanks so much for the reply. I am still struggling to understand when it's best to use robots.txt
I think I understand that url parameters are best handled in the search console parameters tool, and if you want to keep a page out of the index, it's best to use meta noindex rather than blocking it in robots.txt
What would be an example of when you would want to disallow something in robots.txt?
-
For one, the GSC functionality is much easier to use for dealing with URLs having multiple query string parameters. robots.txt processes the statements in order, so you often have to set up a broad disallow, followed by more specific allows, to achieve the same result which can be more easily managed in GSC.
Also, GSC is useful for the "representative URL" setting, if your pages don't necessarily get crawled without the parameter present at all, but you only want one version of the page indexed if the crawler encounters multiple versions. So, this is a little like a dynamic canonical, except you are not specifying which version.

Unsolved Capturing Source Dynamically for UTM Parameters
Does anyone have a tutorial on how to dynamically capture the referring source to be populated in UTM parameters for Google Analytics? We want to syndicate content and be able to see all of the websites that provided referral traffic for this specific objective. We want to set a specific utm_medium and utm_campaign but have the utm_source be dynamic and capture the referring website. If we set a permanent utm_source, it would appear the same for all incoming traffic. Thanks in advance!

Google has deindexed a page it thinks is set to 'noindex', but is in fact still set to 'index'
A page on our WordPress powered website has had an error message thrown up in GSC to say it is included in the sitemap but set to 'noindex'. The page has also been removed from Google's search results. Page is https://www.onlinemortgageadvisor.co.uk/bad-credit-mortgages/how-to-get-a-mortgage-with-bad-credit/ Looking at the page code, plus using Screaming Frog and Ahrefs crawlers, the page is very clearly still set to 'index'. The SEO plugin we use has not been changed to 'noindex' the page. I have asked for it to be reindexed via GSC but I'm concerned why Google thinks this page was asked to be noindexed. Can anyone help with this one? Has anyone seen this before, been hit with this recently, got any advice...?

Adding multi-language sitemaps to robots.txt
I am working on a revamped multi-language site that has moved to Magento. Each language runs off the core coding so there are no sub-directories per language. The developer has created sitemaps which have been uploaded to their respective GWT accounts. They have placed the sitemaps in new directories such as: /sitemap/uk/sitemap.xml /sitemap/de/sitemap.xml I want to add the sitemaps to the robots.txt but can't figure out how to do it. Also should they have placed the sitemaps in a single location with the file identifying each language: /sitemap/uk-sitemap.xml /sitemap/de-sitemap.xml What is the cleanest way of handling these sitemaps and can/should I get them on robots.txt?

Invisible robots.txt?
So here's a weird one... Client comes to me for some simple changes, turns out there are some major issues with the site, one of which is that none of the correct content pages are showing up in Google, just ancillary (outdated) ones. Looks like an issue because even the main homepage isn't showing up with a "site:domain.com" So, I add to Webmaster Tools and, after an hour or so, I get the red bar of doom, "robots.txt is blocking important pages." I check it out in Webmasters and, sure enough, it's a "User agent: * Disallow /" ACK! But wait... there's no robots.txt to be found on the server. I can go to domain.com/robots.txt and see it but nothing via FTP. I upload a new one and, thankfully, that is now showing but I've never seen that before. Question is: can a robots.txt file be stored in a way that can't be seen? Thanks!

Subdomain Removal in Robots.txt with Conditional Logic??
I would like to see if there is a way to add conditional logic to the robots.txt file so that when we push from DEV to PRODUCTION and the robots.txt file is pushed, we don't have to remember to NOT push the robots.txt file OR edit it when it goes live. My specific situation is this: I have www.website.com, dev.website.com and new.website.com and somehow google has indexed the DEV.website.com and NEW.website.com and I'd like these to be removed from google's index as they are causing duplicate content. Should I: a) add 2 new GWT entries for DEV.website.com and NEW.website.com and VERIFY ownership - if I do this, then when the files are pushed to LIVE won't the files contain the VERIFY META CODE for the DEV version even though it's now LIVE? (hope that makes sense) b) write a robots.txt file that specifies "DISALLOW: DEV.website.com/" is that possible? I have only seen examples of DISALLOW with a "/" in the beginning... Hope this makes sense, can really use the help! I'm on a Windows Server 2008 box running ColdFusion websites.

Should I set up a disallow in the robots.txt for catalog search results?
When the crawl diagnostics came back for my site its showing around 3,000 pages of duplicate content. Almost all of them are of the catalog search results page. I also did a site search on Google and they have most of the results pages in their index too. I think I should just disallow the bots in the /catalogsearch/ sub folder, but I'm not sure if this will have any negative effect?
