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.

Can you disallow links via Search Console?
Hey guys, Is it possible in anyway to nofollow links via search console (not disavow) but just nofollow external links pointing to your site? Cheers.

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 -
Meta Robot Tag:Index, Follow, Noodp, Noydir
When should "Noodp" and "Noydir" meta robot tag be used? I have hundreds or URLs for real estate listings on my site that simply use "Index", Follow" without using Noodp and Noydir. Should the listing pages use these Noodp and Noydr also? All major landing pages use Index, Follow, Noodp, Noydir. Is this the best setting in terms of ranking and SEO. Thanks, Alan

Should I use meta noindex and robots.txt disallow?
Hi, we have an alternate "list view" version of every one of our search results pages The list view has its own URL, indicated by a URL parameter I'm concerned about wasting our crawl budget on all these list view pages, which effectively doubles the amount of pages that need crawling When they were first launched, I had the noindex meta tag be placed on all list view pages, but I'm concerned that they are still being crawled Should I therefore go ahead and also apply a robots.txt disallow on that parameter to ensure that no crawling occurs? Or, will Googlebot/Bingbot also stop crawling that page over time? I assume that noindex still means "crawl"... Thanks 🙂

Robots.txt, does it need preceding directory structure?
Do you need the entire preceding path in robots.txt for it to match? e.g: I know if i add Disallow: /fish to robots.txt it will block /fish
Intermediate & Advanced SEO | | Milian
/fish.html
/fish/salmon.html
/fishheads
/fishheads/yummy.html
/fish.php?id=anything But would it block?: en/fish
en/fish.html
en/fish/salmon.html
en/fishheads
en/fishheads/yummy.html
**en/fish.php?id=anything (taken from Robots.txt Specifications)** I'm hoping it actually wont match, that way writing this particular robots.txt will be much easier! As basically I'm wanting to block many URL that have BTS- in such as: http://www.example.com/BTS-something
http://www.example.com/BTS-somethingelse
http://www.example.com/BTS-thingybob But have other pages that I do not want blocked, in subfolders that also have BTS- in, such as: http://www.example.com/somesubfolder/BTS-thingy
http://www.example.com/anothersubfolder/BTS-otherthingy Thanks for listening0 -
