      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"?

          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.

                Desktop & Mobile XML Sitemap Submitted But Only Desktop Sitemap Indexed On Google Search Console

                Hi! The Problem We have submitted to GSC a sitemap index. Within that index there are 4 XML Sitemaps. Including one for the desktop site and one for the mobile site. The desktop sitemap has 3300 URLs, of which Google has indexed (according to GSC) 3,000 (approx). The mobile sitemap has 1,000 URLs of which Google has indexed 74 of them. The pages are crawlable, the site structure is logical. And performing a Landing Page URL search (showing only Google/Organic source/medium) on Google Analytics I can see that hundreds of those mobile URLs are being landed on. A search on mobile for a longtail keyword from a (randomly selected) page shows a result in the SERPs for the mobile page that judging by GSC has not been indexed. Could this be because we have recently added rel=alternate tags on our desktop pages (and of course corresponding canonical ones on mobile). Would Google then 'not index' rel=alternate page versions? Thanks for any input on this one. PmHmG

                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.

                How to set up internal linking with subcategories?

                I'm building a new website and am setting up internal link structure with subcategories and hoping to do so with best Seo practices in mind.  When linking to a subcategory's main page, would I make the internal link  www.xxx.com/fishing/ or www.xxx.com/fishing/index.html or does it matter?  I'm just trying to avoid duplicate content I guess, if Google saw each page as a separate page.  Any other cautions when using subdirectories in my navigation?

                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

                Links under Meta Description when performing a search

                Doing research for clients, I have came across seeing sites displaying hyperlinks underneath their own meta description. keywords that I have googled that result with hyperlinks displaying under meta descriptions: Google'd: iacquire (brand) bmw wheels (Beyern Wheels, position 1) aftermarket bmw wheels (MMR Wheels, position 2) These companys have hyperlinks underneath their descriptions. Anyone have any ideas why this happens or how it happens?

                Mobile URL parameter (Redirection to desktop)

                Hello, We have a parallel mobile website and recently we implemented a link pointing to the desktop website. This redirect is happening via a javascript code and results in a url followed by this paramenter: ?m=off Example:
                http://www.m.website.com                                 redirects to:
                http://www.website.com/?m=off Questions: Will the "http://www.website.com/?m=off" be considered duplicate content with "http://www.website.com" since they both return the same content? Is there any possibility that Google will take into consideration the url ending in "/?m=off"? How should we treat this new url? The webmaster tools URL parameter configuration at the moment isn't experiencing problems but should we submit the parameter anyway in order not to be indexed or should we wait first and see the error response? In case we should submit this for removal... what's the best way to do it? Like this? Parameter: ?m=off Does this parameter change page content seen by the user? - doesn't affect page content Any help is much appreciated.
                Thank you!

                Removing robots.txt on WordPress site problem

                Hi..am a little confused since I ticked the box in WordPress to allow search engines to now crawl my site (previously asked for them not to) but Google webmaster tools is telling me I still have robots.txt blocking them so am unable to submit the sitemap. Checked source code and the robots instruction has gone so a little lost. Any ideas please?
