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.

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 -
How do I "undo" or remove a Google Search Console change of address?
I have a client that set a change of address in Google Search Console where they informed Google that their preferred domain was a subdomain, and now they want Google to also consider their base domain (without the change of address). How do I get the change of address in Google search console removed?

Set Canonical for Paginated Content
Hi Guys, This is a follow up on this thread: http://moz.com/community/q/dynamic-url-parameters-woocommerce-create-404-errors# I would like to know how I can set a canonical link in Wordpress/Woocommerce which points to "View All" on category pages on our webshop.
Technical SEO | | jeeyer
The categories on my website can be viewed as 24/48 or All products but because the quanity constantly changes viewing 24 or 48 products isn't always possible. To point Google in the right direction I want to let them know that "View All" is the best way to go.
I've read that Google's crawler tries to do this automatically but not sure if this is the case on on my website. Here is some more info on the issue: https://support.google.com/webmasters/answer/1663744?hl=en

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!

Site disappearing from search for a certain keyword
I was wondering if someone has encountered the same problem as me. I was doing some changes on the frontpage of one of my clients' website, especially some redirections, and my site has disappeared from Google for the main keyword on the page. So, if I look for my page on Google, instead of seeing my page first, I no longer see my page, at all. All I've done was a 301 redirection from index.html to the domain name. Now, I changed everything back to how it was before. More precisely, I've done that 2 weeks ago. But, no change in Google. I checked Bing and Yahoo, my site appears first when I search for that specific keyword. Any ideas how long will it take for Google to see that I am not doing anything wrong with redirections? Or any idea at all?

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!
