      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.

                Unsolved Google Search Console Still Reporting Errors After Fixes

                google search console sitemaps 400 errors

                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.

                Should search pages be indexed?

                Hey guys, I've always believed that search pages should be no-indexed but now I'm wondering if there is an argument to index them? Appreciate any thoughts!

                "Search Box Optimization"

                A client of ours recently received en email from a random SEO "company" claiming they could increase website traffic using a technique known as "search box optimization". Essentially, they are claiming they can insert a company name into the autocomplete results on Google. Clearly, this isn't a legitimate service - however, is it a well known technique? Despite our recommendation to not move forward with it, the client is still very intrigued. Here is a video of a similar service:

                Will an XML sitemap override a robots.txt

                I have a client that has a robots.txt file that is blocking an entire subdomain, entirely by accident. Their original solution, not realizing the robots.txt error, was to submit an xml sitemap to get their pages indexed. I did not think this tactic would work, as the robots.txt would take precedent over the xmls sitemap. But it worked... I have no explanation as to how or why. Does anyone have an answer to this? or any experience with a website that has had a clear Disallow: / for months , that somehow has pages in the index?

                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?

                CGI Parameters: should we worry about duplicate content?

                Hi, My question is directed to CGI Parameters. I was able to dig up a bit of content on this but I want to make sure I understand the concept of CGI parameters and how they can affect indexing pages. Here are two pages: No CGI parameter appended to end of the URL: http://www.nytimes.com/2011/04/13/world/asia/13japan.html CGI parameter appended to the end of the URL: http://www.nytimes.com/2011/04/13/world/asia/13japan.html?pagewanted=2&ref=homepage&src=mv Questions: Can we safely say that CGI parameters = URL parameters that append to the end of a URL? Or are they different? And given that you have rel canonical implemented correctly on your pages, search engines will move ahead and index only the URL that is specified in that tag? Thanks in advance for giving your insights. Look forward to your response. Best regards, Jackson
