Robots Disallow Backslash - Is it right command
-
Bit skeptical, as due to dynamic url and some other linkage issue, google has crawled url with backslash and asterisk character
ex - www.xyz.com/\/index.php?option=com_product
www.xyz.com/\"/index.php?option=com_product
Now %5c is the encoded version of \ - backslash & %22 is encoded version of asterisk
Need to know for command :-
User-agent: * Disallow: \As am disallowing all backslash url through this - will it only remove the backslash url which are duplicates or the entire site,
-
Thanks, you seem lucky to me.. Almost after 2 month i have got the code for making all these encoded url's redirect correctly. Finally, now if one types
http://www.mycarhelpline.com/\"/index.php?option=com_latestnews&view=list&Itemid=10
then he's redirected through 301 to the correct url
http://www.mycarhelpline.com/index.php?option=com_latestnews&view=list&Itemid=10

Hello Gagan,
I think the best way to handle this would be using the rel canonical tag or rewriting the URLs to get rid of the parameters and replace them with something more user-friendly.
The rel canonical tag would be the easiest way out of those two. I notice the version without the encoding (e.g. http://www.mycarhelpline.com/index.php?option=com_latestnews&view=list&Itemid=10 ) have a rel canonical tag that correctly references itself as the canonical version. However, the encoded URLs (e.g. http://www.mycarhelpline.com/\"/index.php?option=com_latestnews&view=list&Itemid=10) which is actually http://www.mycarhelpline.com/\"/index.php?option=com_latestnews&view=list&Itemid=10 does NOT have a rel canonical tag.
If the version with the backslash had a rel canonical tag stating that the following URL is canonical it would solve your issue, I think.
Canonical URL:
http://www.mycarhelpline.com/index.php?option=com_latestnews&view=list&Itemid=10 -
Sure, If i show you some url they are crawled as :-
Sample Incorrect URLs crawled and reported as duplicate one in Google Webmaster & Moz too

http://www.mycarhelpline.com/\"/index.php?option=com_latestnews&view=list&Itemid=10
| http://www.mycarhelpline.com/\"/index.php?option=com_newcar&view=category&Itemid=2 |
|
Correct URL
http://www.mycarhelpline.com/index.php?option=com_latestnews&view=list&Itemid=10
http://www.mycarhelpline.com/index.php?option=com_newcar&view=search&Itemid=2
What we found online
Since URLs often contain characters outside the ASCII set, the URL has to be converted into a valid ASCII format. URL encoding replaces unsafe ASCII characters with a "%" followed by two hexadecimal digits. URLs cannot contain spaces.
%22 reflects - " and %5c as \ (forward slash)
We intend to remove these duplicate one created having %22 and %5c within them..
Many thanks

I am not entirely sure I understood your question as intended, but I will do my best to answer.
I would not put this in my robots.txt flie because it could possibly be misunderstood as a forward slash, in which case your entire domain would be blocked:
Disallow: \
We can possibly provide you with some alternative suggestions on how to keep Google from crawling those pages if you could share some real examples.
It may be best to rewrite/redirect those URls instead since they don't seem to be the canonical version you intend to be presented to the user.

Will disallowing URL's in the robots.txt file stop those URL's being indexed by Google
I found a lot of duplicate title tags showing in Google Webmaster Tools. When I visited the URL's that these duplicates belonged to, I found that they were just images from a gallery that we didn't particularly want Google to index. There is no benefit to the end user in these image pages being indexed in Google. Our developer has told us that these urls are created by a module and are not "real" pages in the CMS. They would like to add the following to our robots.txt file Disallow: /catalog/product/gallery/ QUESTION: If the these pages are already indexed by Google, will this adjustment to the robots.txt file help to remove the pages from the index? We don't want these pages to be found.

Wildcarding Robots.txt for Particular Word in URL
Hey All, So I know that this isn't a standard robots.txt, I'm aware of how to block or wildcard certain folders but I'm wondering whether it's possible to block all URL's with a certain word in it? We have a client that was hacked a year ago and now they want us to help remove some of the pages that were being autogenerated with the word "viagra" in it. I saw this article and tried implementing it https://builtvisible.com/wildcards-in-robots-txt/ and it seems that I've been able to remove some of the URL's (although I can't confirm yet until I do a full pull of the SERPs on the domain). However, when I test certain URL's inside of WMT it still says that they are allowed which makes me think that it's not working fully or working at all. In this case these are the lines I've added to the robots.txt Disallow: /*&viagra Disallow: /*&Viagra I know I have the solution of individually requesting URL's to be removed from the index but I want to see if anybody has every had success with wildcarding URL's with a certain word in their robots.txt? The individual URL route could be very tedious. Thanks! Jon

Should I disallow all URL query strings/parameters in Robots.txt?
Webmaster Tools correctly identifies the query strings/parameters used in my URLs, but still reports duplicate title tags and meta descriptions for the original URL and the versions with parameters. For example, Webmaster Tools would report duplicates for the following URLs, despite it correctly identifying the "cat_id" and "kw" parameters: /Mulligan-Practitioner-CD-ROM
Intermediate & Advanced SEO | | jmorehouse
/Mulligan-Practitioner-CD-ROM?cat_id=87
/Mulligan-Practitioner-CD-ROM?kw=CROM Additionally, theses pages have self-referential canonical tags, so I would think I'd be covered, but I recently read that another Mozzer saw a great improvement after disallowing all query/parameter URLs, despite Webmaster Tools not reporting any errors. As I see it, I have two options: Manually tell Google that these parameters have no effect on page content via the URL Parameters section in Webmaster Tools (in case Google is unable to automatically detect this, and I am being penalized as a result). Add "Disallow: *?" to hide all query/parameter URLs from Google. My concern here is that most backlinks include the parameters, and in some cases these parameter URLs outrank the original. Any thoughts?0 -

Dilemma about "images" folder in robots.txt
Hi, Hope you're doing well. I am sure, you guys must be aware that Google has updated their webmaster technical guidelines saying that users should allow access to their css files and java-scripts file if it's possible. Used to be that Google would render the web pages only text based. Now it claims that it can read the css and java-scripts. According to their own terms, not allowing access to the css files can result in sub-optimal rankings. "Disallowing crawling of Javascript or CSS files in your site’s robots.txt directly harms how well our algorithms render and index your content and can result in suboptimal rankings."http://googlewebmastercentral.blogspot.com/2014/10/updating-our-technical-webmaster.htmlWe have allowed access to our CSS files. and Google bot, is seeing our webapges more like a normal user would do. (tested it in GWT)Anyhow, this is my dilemma. I am sure lot of other users might be facing the same situation. Like any other e commerce companies/websites.. we have lot of images. Used to be that our css files were inside our images folder, so I have allowed access to that. Here's the robots.txt --> http://www.modbargains.com/robots.txtRight now we are blocking images folder, as it is very huge, very heavy, and some of the images are very high res. The reason we are blocking that is because we feel that Google bot might spend almost all of its time trying to crawl that "images" folder only, that it might not have enough time to crawl other important pages. Not to mention, a very heavy server load on Google's and ours. we do have good high quality original pictures. We feel that we are losing potential rankings since we are blocking images. I was thinking to allow ONLY google-image bot, access to it. But I still feel that google might spend lot of time doing that. **I was wondering if Google makes a decision saying, hey let me spend 10 minutes for google image bot, and let me spend 20 minutes for google-mobile bot etc.. or something like that.. , or does it have separate "time spending" allocations for all of it's bot types. I want to unblock the images folder, for now only the google image bot, but at the same time, I fear that it might drastically hamper indexing of our important pages, as I mentioned before, because of having tons & tons of images, and Google spending enough time already just to crawl that folder.**Any advice? recommendations? suggestions? technical guidance? Plan of action? Pretty sure I answered my own question, but I need a confirmation from an Expert, if I am right, saying that allow only Google image access to my images folder. Sincerely,Shaleen Shah

Disallowed Pages Still Showing Up in Google Index. What do we do?
We recently disallowed a wide variety of pages for www.udemy.com which we do not want google indexing (e.g., /tags or /lectures). Basically we don't want to spread our link juice around to all these pages that are never going to rank. We want to keep it focused on our core pages which are for our courses. We've added them as disallows in robots.txt, but after 2-3 weeks google is still showing them in it's index. When we lookup "site: udemy.com", for example, Google currently shows ~650,000 pages indexed... when really it should only be showing ~5,000 pages indexed. As another example, if you search for "site:udemy.com/tag", google shows 129,000 results. We've definitely added "/tag" into our robots.txt properly, so this should not be happening... Google showed be showing 0 results. Any ideas re: how we get Google to pay attention and re-index our site properly?

Block an entire subdomain with robots.txt?
Is it possible to block an entire subdomain with robots.txt? I write for a blog that has their root domain as well as a subdomain pointing to the exact same IP. Getting rid of the option is not an option so I'd like to explore other options to avoid duplicate content. Any ideas?
