Can anybody please explain the correct robots.txt command for the following scenario.
I would like to allow access to:
/directory/subdirectory/..
But I would also like to restrict access to /directory/ not withstanding the above exception.
Be aware that there is no real official standard and that any web crawler may happily ignore your robots.txt
According to a Google groups post, the following works at least with GoogleBot;
User-agent: Googlebot
Disallow: /directory/
Allow: /directory/subdirectory/
I would recommend using Google's robot tester. Utilize Google Webmaster tools - https://support.google.com/webmasters/answer/6062598?hl=en
You can edit and test URLs right in the tool, plus you get a wealth of other tools as well.
If these are truly directories then the accepted answer is probably your best choice. But, if you're writing an application and the directories are dynamically generated paths (a.k.a. contexts, routes, etc), then you might want to use meta tags instead of defining it in the robots.txt. This gives you the advantage of not having to worry about how different browsers may interpret/prioritize the access to the subdirectory path.
You might try something like this in the code:
if is_parent_directory_path
<meta name="robots" content="noindex, nofollow">
end

full disclaimer, I am not a programer, I am an SEO trying to learn how to not rely on my developer for every little question I have.
Currently my issue is this. I use Screaming Frog to crawl my sites to layout the page titles, meta descriptions, h1, h2, etc so I can more easily plan out my changes.
The other day I wanted to run a report for my client and my own company website and got the following back.
So I know robots.txt is a way to make pages on your site but not have google crawl them. What I don't know is why an entire site would have this message as opposed to just some pages.
Can anyone give advice on how to fix this or links to how to's? I get this issue a lot and would like to educate myself so I don't have to wait for someone else. I get these as well when I try indexing websites on Google Search Console.
Many Thanks
What I don't know is why an entire site would have this message as
apposed to just some pages.
The robots.txt for your website has not been written properly if the intention is to index its content.
Or Screaming Frog might have a but if indeed the robots.txt file is written properly.
Or some webmaster decided the content was not worth indexing on Google or that bots would eat too much bandwidth (as in not being selective to restrict access).
Checking the current robots.txt file on that website, I see this content:
User-Agent: *
Disallow:
Which means the any page of that website is allowed to be crawled by any crawler (here the explanation of that file's syntax: https://moz.com/learn/seo/robotstxt)
So the current file should not cause that error OP mentions. Seeing that this question is from June 30/2017 and the robots.txt file was last modified on Jul 11/2017, it seems since this question was opened the OP may have already fixed whatever problem they had.
I came across a site that uses the following in its robots.txt file:
User-agent: *
Disallow: /*.php$
So what does it do?
Will it prevent web crawlers from crawling the following URLs?
https://example.com/index.php
https://example.com/index.php?page=Events&action=Upcoming
Will it block subdomains too?
https://subdomain.example.com/index.php
So what does it do?
By spec it means "URLs starting with /*.php$", which isn't very useful. There might be engines out that which support some custom syntax for it. I know some support wild cards, but that looks like regular expression syntax and I've not heard of anything that supports that in robots.txt.
Will it prevent web crawlers from crawling the following URLs?
By spec: No.
If anything supports regexs, then it will block the first one but not the second one.
Will it block subdomains too?
No. Each origin is independent when it comes to robots.txt. The subdomain site would need its own copy of the resource.
It looks like regular expressions but regular expressions are not in the spec. But Google and Bing both honours wildcards (*) and end-of-url markers ($). You can try your robots.txt rules here.
I'm working with an e-commerce system at the moment that is throwing up hundreds of potential duplicate page urls and trying to work out how to hide them via robots.txt untill the developers are able to sort there ...... out.
I have managed to block most of them but got stuck on the last type so the question is:
I have 4 urls to the same product page with the below structure, how do I block the first one but not the others.
www.example.com/ProductPage
www.example.com/category/ProductPage
www.example.com/category/subcategory/ProductPage
www.example.com/category/subcategory/ProductPage/assessorypage
So far the only idea I can come up with is using:
Disallow: /*?id=*/
this however blocks everything…
EDIT: I believe I may have found a way to do it by setting up a robots.txt file to disallow all then just allow the specific paths I want again below that and then…once again disallow any specific paths after that.
Anyone know if this has a negative effect on SEO using disallow > allow > disallow.
You could set the meta tag for the rel="canonical" property. This will help search engines know which url is the 'right' one and not have more than one URL per product in search results.
Read here for more information
http://plus.google.com/robots.txt has the following contents:
User-agent: *
Disallow: /_/
I'm assuming this means search engines are allowed to index anything in the first level off the root and nothing further?
I believe those lines are used to deny robots access to URLs like
https://plus.google.com/_/apps-static/_/ss/landing/...
and
https://plus.google.com/_/apps-static/_/js/landing/....
These URLs mainly appear to be CSS, Javascript, and JSON, but there might be other things (that are more valuable to search engines) which aren't immediately obvious.
hi sirs what's the best way to prevent google from showing of a folder in the search engine ?, like e.g www.example.com/support , what should i do if I want the support folder to disappear in google ?
the first thing I did was place a 'robots.txt' file and include this code
User-agent: *
Disallow: /support/etc
but the results is a total disaster, am not able to use the support page anymore unless i remove the robots.txt
what's the best thing to do ?
robots.txt shouldnt affect the way your page function. If in doubt, you can use tools to generate like http://www.searchenginepromotionhelp.com/m/robots-text-creator/simple-robots-creator.php or http://www.seochat.com/seo-tools/robots-generator/
When dissallowing in robots file, you can explicitly specify a file or subfolder rather than just a folder.
You can also use meta tag in your document to tell the crawler not to use it
<META NAME="ROBOTS" CONTENT="NOINDEX, NOFOLLOW">

A robots.txt file is the right way to do this. Your example is correct for blocking the /support/etc directory and its descendants.

It doesn't make sense that a robots.txt file would affect the way your site functions, and certainly it should never affect which pages can be accessed by a human. I suspect something else is awry -- check your server logs to see what kinds of errors are being recorded.
While not the preferred method of limiting robot access, Google talks about using a noindex meta tag here. This will also prevent the various pages from showing up if they are linked to by a site other than your own.
A good discussion of limiting bots that visit your site can be found here.
