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.

Hide sitelinks from Google search results
Does anyone have any recommendations on how you can tell Google (hopefully via a URL) not to index that page of a website? I have tried through SEO Yoast to hide certain sitemaps (which has worked to a degree) but certain functionalities of Wordpress websites show links without them actually being part of a "sitemap" so those links are harder to hide. I'm having an issue with one of my websites - the sitelinks that Google is suggesting are nowhere near the most popular pages and I know that you can't make recommendations through Google not to show certain pages through Search Console. anymore. Any suggestions are greatly appreciated! Thanks!

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?

Robots.txt and Multiple Sitemaps
Hello, I have a hopefully simple question but I wanted to ask to get a "second opinion" on what to do in this situation. I am working on a clients robots.txt and we have multiple sitemaps. Using yoast I have my sitemap_index.xml and I also have a sitemap-image.xml I do put them in google and bing by hand but wanted to have it added into the robots.txt for insurance. So my question is, when having multiple sitemaps called out on a robots.txt file does it matter if one is before the other? From my reading it looks like you can have multiple sitemaps called out, but I wasn't sure the best practice when writing it up in the file. Example: User-agent: * Disallow: Disallow: /cgi-bin/ Disallow: /wp-admin/ Disallow: /wp-content/plugins/ Sitemap: http://sitename.com/sitemap_index.xml Sitemap: http://sitename.com/sitemap-image.xml Thanks a ton for the feedback, I really appreciate it! :) J

Does Bing ignore robots txt files?
Bonjour from "Its a miracle is not raining" Wetherby Uk 🙂 Ok here goes... Why despite a robots text file excluding indexing to site http://lewispr.netconstruct-preview.co.uk/ is the site url being indexed in Bing bit not Google? Does bing ignore robots text files or is there something missing from http://lewispr.netconstruct-preview.co.uk/robots.txt I need to add to stop bing indexing a preview site as illustrated below. http://i216.photobucket.com/albums/cc53/zymurgy_bucket/preview-bing-indexed.jpg Any insights welcome 🙂

OK to block /js/ folder using robots.txt?
I know Matt Cutts suggestions we allow bots to crawl css and javascript folders (http://www.youtube.com/watch?v=PNEipHjsEPU) But what if you have lots and lots of JS and you dont want to waste precious crawl resources? Also, as we update and improve the javascript on our site, we iterate the version number ?v=1.1... 1.2... 1.3... etc. And the legacy versions show up in Google Webmaster Tools as 404s. For example: http://www.discoverafrica.com/js/global_functions.js?v=1.1
Technical SEO | | AndreVanKets
http://www.discoverafrica.com/js/jquery.cookie.js?v=1.1
http://www.discoverafrica.com/js/global.js?v=1.2
http://www.discoverafrica.com/js/jquery.validate.min.js?v=1.1
http://www.discoverafrica.com/js/json2.js?v=1.1 Wouldn't it just be easier to prevent Googlebot from crawling the js folder altogether? Isn't that what robots.txt was made for? Just to be clear - we are NOT doing any sneaky redirects or other dodgy javascript hacks. We're just trying to power our content and UX elegantly with javascript. What do you guys say: Obey Matt? Or run the javascript gauntlet?0
