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.

Blocking Affiliate Links via robots.txt
Hi, I work with a client who has a large affiliate network pointing to their domain which is a large part of their inbound marketing strategy. All of these links point to a subdomain of affiliates.example.com, which then redirects the links through a 301 redirect to the relevant target page for the link. These links have been showing up in Webmaster Tools as top linking domains and also in the latest downloaded links reports. To follow guidelines and ensure that these links aren't counted by Google for either positive or negative impact on the site, we have added a block on the robots.txt of the affiliates.example.com subdomain, blocking search engines from crawling the full subddomain. The robots.txt file is the following code: User-agent: * Disallow: / We have authenticated the subdomain with Google Webmaster Tools and made certain that Google can reach and read the robots.txt file. We know they are being blocked from reading the affiliates subdomain. However, we added this affiliates subdomain block a few weeks ago to the robots.txt, but links are still showing up in the latest downloads report as first being discovered after we added the block. It's been a few weeks already, and we want to make sure that the block was implemented properly and that these links aren't being used to negatively impact the site. Any suggestions or clarification would be helpful - if the subdomain is being blocked for the search engines, why are the search engines following the links and reporting them in the www.example.com subdomain GWMT account as latest links. And if the block is implemented properly, will the total number of links pointing to our site as reported in the links to your site section be reduced, or does this not have an impact on that figure?From a development standpoint, it's a much easier fix for us to adjust the robots.txt file than to change the affiliate linking connection from a 301 to a 302, which is why we decided to go with this option.Any help you can offer will be greatly appreciated.Thanks,Mark

Are my Domain URLs correctly set up?
Hi Im struggling with this probably easy concept, so I am sure one of you guys out there can answer it fairly easy! My website is over50choices.co.uk and whilst using the free tools in Majestic it said that I had: 77 Referring Domains pointing to www.over50choices.co.uk and only 35 pointing to www.over50choices.co.uk/ And in Moz it said: The URL you've entered redirects to another URL. We're showing results for www.over50choices.co.uk/ since it is likely to have more accurate link metrics. See data for over50choices.co.uk instead? Does this mean that my domains arent set up correctly and are acting as separate domains - should one be pointing to the other? Your help appreciated. Ash

Do I need robots.txt and meta robots?
If I can manage to tell crawlers what I do and don't want them to crawl for my whole site via my robots.txt file, do I still need meta robots instructions?

Wordpress Robots.txt Sitemap submission?
Alright, my question comes directly from this article by SEOmoz http://www.seomoz.org/learn-seo/r... Yes, I have submitted the sitemap to google, bing's webmaster tools and and I want to add the location of our site's sitemaps and does it mean that I erase everything in the robots.txt right now and replace it with? <code>User-agent: * Disallow: Sitemap: http://www.example.com/none-standard-location/sitemap.xml</code> <code>???</code> because Wordpress comes with some default disallows like wp-admin, trackback, plugins. I have also read this, but was wondering if this is the correct way to add sitemap on Wordpress Robots.txt. [http://www.seomoz.org/q/removing-...](http://www.seomoz.org/q/removing-robots-txt-on-wordpress-site-problem) I am using Multisite with Yoast plugin so I have more than one sitemap.xml to submit Do I erase everything in Robots.txt and replace it with how SEOmoz recommended? hmm that sounds not right. like <code> <code>

Google (GWT) says my homepage and posts are blocked by Robots.txt
I guys.. I have a very annoying issue.. My Wordpress-blog over at www.Trovatten.com has some indexation-problems.. Google Webmaster Tools data:
Technical SEO | | FrederikTrovatten22
GWT says the following: "Sitemap contains urls which are blocked by robots.txt." and shows me my homepage and my blogposts.. This is my Robots.txt: http://www.trovatten.com/robots.txt
"User-agent: *
Disallow: /wp-admin/
Disallow: /wp-includes/ Do you have any idea why it says that the URL's are being blocked by robots.txt when that looks how it should?
I've read a couple of places that it can be because of a Wordpress Plugin that is creating a virtuel robots.txt, but I can't validate it.. 1. I have set WP-Privacy to crawl my site
2. I have deactivated all WP-plugins and I still get same GWT-Warnings. Looking forward to hear if you have an idea that might work!0 -
What is the sense of robots.txt?
Using robots.txt to prevent search engine from indexing the page is not a good idea. so what is the sense of robots.txt? just for attracting robots to crawl sitemap?
