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.

If I block a URL via the robots.txt - how long will it take for Google to stop indexing that URL?

If Robots.txt have blocked an Image (Image URL) but the other page which can be indexed has this image, how is the image treated?
Hi MOZers, This probably is a dumb question but I have a case where the robots.tags has an image url blocked but this image is used on a page (lets call it Page A) which can be indexed. If the image on Page A has an Alt tags, then how is this information digested by crawlers? A) would Google totally ignore the image and the ALT tags information? OR B) Google would consider the ALT tags information? I am asking this because all the images on the website are blocked by robots.txt at the moment but I would really like website crawlers to crawl the alt tags information. Chances are that I will ask the webmaster to allow indexing of images too but I would like to understand what's happening currently. Looking forward to all your responses 🙂 Malika

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

Block in robots.txt instead of using canonical?
When I use a canonical tag for pages that are variations of the same page, it basically means that I don't want Google to index this page. But at the same time, spiders will go ahead and crawl the page. Isn't this a waste of my crawl budget? Wouldn't it be better to just disallow the page in robots.txt and let Google focus on crawling the pages that I do want indexed? In other words, why should I ever use rel=canonical as opposed to simply disallowing in robots.txt?

Robots.txt: how to exclude sub-directories correctly?
Hello here, I am trying to figure out the correct way to tell SEs to crawls this: http://www.mysite.com/directory/ But not this: http://www.mysite.com/directory/sub-directory/ or this: http://www.mysite.com/directory/sub-directory2/sub-directory/... But with the fact I have thousands of sub-directories with almost infinite combinations, I can't put the following definitions in a manageable way: disallow: /directory/sub-directory/ disallow: /directory/sub-directory2/ disallow: /directory/sub-directory/sub-directory/ disallow: /directory/sub-directory2/subdirectory/ etc... I would end up having thousands of definitions to disallow all the possible sub-directory combinations. So, is the following way a correct, better and shorter way to define what I want above: allow: /directory/$ disallow: /directory/* Would the above work? Any thoughts are very welcome! Thank you in advance. Best, Fab.

Recovering from robots.txt error
Hello, A client of mine is going through a bit of a crisis. A developer (at their end) added Disallow: / to the robots.txt file. Luckily the SEOMoz crawl ran a couple of days after this happened and alerted me to the error. The robots.txt file was quickly updated but the client has found the vast majority of their rankings have gone. It took a further 5 days for GWMT to file that the robots.txt file had been updated and since then we have "Fetched as Google" and "Submitted URL and linked pages" in GWMT. In GWMT it is still showing that that vast majority of pages are blocked in the "Blocked URLs" section, although the robots.txt file below it is now ok. I guess what I want to ask is: What else is there that we can do to recover these rankings quickly? What time scales can we expect for recovery? More importantly has anyone had any experience with this sort of situation and is full recovery normal? Thanks in advance!

Blocking Pages Via Robots, Can Images On Those Pages Be Included In Image Search
Hi! I have pages within my forum where visitors can upload photos. When they upload photos they provide a simple statement about the photo but no real information about the image,definitely not enough for the page to be deemed worthy of being indexed. The industry however is one that really leans on images and having the images in Google Image search is important to us. The url structure is like such: domain.com/community/photos/~username~/picture111111.aspx I wish to block the whole folder from Googlebot to prevent these low quality pages from being added to Google's main SERP results. This would be something like this: User-agent: googlebot Disallow: /community/photos/ Can I disallow Googlebot specifically rather than just using User-agent: * which would then allow googlebot-image to pick up the photos? I plan on configuring a way to add meaningful alt attributes and image names to assist in visibility, but the actual act of blocking the pages and getting the images picked up... Is this possible? Thanks! Leona

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?
