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.

SEO Best Practices regarding Robots.txt disallow
I cannot find hard and fast direction about the following issue: It looks like the Robots.txt file on my server has been set up to disallow "account" and "search" pages within my site, so I am receiving warnings from the Google Search console that URLs are being blocked by Robots.txt. (Disallow: /Account/ and Disallow: /?search=). Do you recommend unblocking these URLs? I'm getting a warning that over 18,000 Urls are blocked by robots.txt. ("Sitemap contains urls which are blocked by robots.txt"). Seems that I wouldn't want that many urls blocked. ? Thank you!!

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.

How to handle a blog subdomain on the main sitemap and robots file?
Hi, I have some confusion about how our blog subdomain is handled in our sitemap. We have our main website, example.com, and our blog, blog.example.com. Should we list the blog subdomain URL in our main sitemap? In other words, is listing a subdomain allowed in the root sitemap? What does the final structure look like in terms of the sitemap and robots file? Specifically: **example.com/sitemap.xml ** would I include a link to our blog subdomain (blog.example.com)? example.com/robots.xml would I include a link to BOTH our main sitemap and blog sitemap? blog.example.com/sitemap.xml would I include a link to our main website URL (even though it's not a subdomain)? blog.example.com/robots.xml does a subdomain need its own robots file? I'm a technical SEO and understand the mechanics of much of on-page SEO.... but for some reason I never found an answer to this specific question and I am wondering how the pros do it. I appreciate your help with this.

Should comments and feeds be disallowed in robots.txt?
Hi My robots file is currently set up as listed below. From an SEO point of view is it good to disallow feeds, rss and comments? I feel allowing comments would be a good thing because it's new content that may rank in the search engines as the comments left on my blog often refer to questions or companies folks are searching for more information on. And the comments are added regularly. What's your take? I'm also concerned about the /page being blocked. Not sure how that benefits my blog from an SEO point of view as well. Look forward to your feedback. Thanks. Eddy User-agent: Googlebot Crawl-delay: 10 Allow: /* User-agent: * Crawl-delay: 10 Disallow: /wp- Disallow: /feed/ Disallow: /trackback/ Disallow: /rss/ Disallow: /comments/feed/ Disallow: /page/ Disallow: /date/ Disallow: /comments/ # Allow Everything Allow: /*

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!

Soft 404's from pages blocked by robots.txt -- cause for concern?
We're seeing soft 404 errors appear in our google webmaster tools section on pages that are blocked by robots.txt (our search result pages). Should we be concerned? Is there anything we can do about this?
