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 Google Search Console Still Reporting Errors After Fixes
Hello, I'm working on a website that was too bloated with content. We deleted many pages and set up redirects to newer pages. We also resolved an unreasonable amount of 400 errors on the site. I also removed several ancient sitemaps that listed content deleted years ago that Google was crawling. According to Moz and Screaming Frog, these errors have been resolved. We've submitted the fixes for validation in GSC, but the validation repeatedly fails. What could be going on here? How can we resolve these error in GSC.

Google Search Console Not Sending Messages
One of our sites received a Manual Penalty for unnatural links by Google. However, we never received a message in Google Search Console or an email about the manual action. The only reason we knew about the penalty is by the obvious drop in rankings, then signing into search console to look for any manual actions, which we found. Since then, we have submitted a disavow file and a reconsideration request. However, once again we did not receive an email or message in search console that shows confirmation of the disavow or that they received the reconsideration request. The disavow file does show up after I upload it, and it says it was successfully uploaded... but no messages or emails. After many hours of investigating the various canonical versions of our website on Search Console, we found out that there were several “owners” of the various canonical versions of our site that had “could not find the email address” as a site owner. We found out that these were previous employees who no longer worked with the company and their email address was deleted. After unverifying these site owners, (all the ones that had “could not find the email address” as the site owner), the notifications, emails and messages in Search Console started to appear. However, the only place they did not appear, is the main canonical version of our site. Of course, the main canonical version of our site (https://www) is the version that we uploaded the disavow and reconsideration request. This is the canonical version of the site that we need to receive these messages to know if our reconsideration request was granted! We’ve just reuploaded the disavow file and reconsideration request to all of the other canonical versions (2 of the 3 received the message about the penalty)…. and we are currently awaiting a response. Has anybody else had problems with not receiving notifications in search console due to deleted email addresses?

Robots.txt & meta noindex--site still shows up on Google Search
I have set up my robots.txt like this: User-agent: *
Technical SEO | | RoxBrock
Disallow: / and I have this meta tag in my on a Wordpress site, set up with SEO Yoast name="robots" content="noindex,follow"/> I did "Fetch as Google" on my Google Search Console My website is still showing up in the search results and it says this: "A description for this result is not available because of this site's robots.txt" This site has not shown up for years and now it is ranking above my site that I want to rank for this keyword. How do I get Google to ignore this site? This seems really weird and I'm confused how a site with little content, that has not been updated for years can rank higher than a site that is constantly updated and improved.1 -

Log in, sign up, user registration and robots
Hi all, We have an accommodation site that asks users only to register when they want to book a room, in the last step. Though this is the ideal situation when you have tons of users, nowadays we are having around 1500 - 2000 per day and making tests we found out that if we ask for a registration (simple, 1 click FB) we mail them all and through a good customer service we are increasing our sales. That is why, we would like to ask users to register right after the home page ie Home/accommodation or and all the rest. I am not sure how can I make to make that content still visible to robots.

Will the authentication process block google crawling it? Maybe something we can do? We are not completely sure how to proceed so any tip would be appreciated. Thank you all for answering.3 -
Should I block Map pages with robots.txt?
Hello, I have a website that was started in 1999. On the website I have map pages for each of the offices listed on my site, for which there are about 120. Each of the 120 maps is in a whole separate html page. There is no content in the page other than the map. I know all of the offices love having the map pages so I don't want to remove the pages. So, my question is would these pages with no real content be hurting the rankings of the other pages on our site? Therefore, should I block the pages with my robots.txt? Would I also have to remove these pages (in webmaster tools?) from Google for blocking by robots.txt to really work? I appreciate your feedback, thanks!

Google indexing despite robots.txt block
Hi This subdomain has about 4'000 URLs indexed in Google, although it's blocked via robots.txt: https://www.google.com/search?safe=off&q=site%3Awww1.swisscom.ch&oq=site%3Awww1.swisscom.ch This has been the case for almost a year now, and it does not look like Google tends to respect the blocking in http://www1.swisscom.ch/robots.txt Any clues why this is or what I could do to resolve it? Thanks!

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?
