Robots.txt and Magento
-
HI,
I am working on getting my robots.txt up and running and I'm having lots of problems with the robots.txt my developers generated. www.plasticplace.com/robots.txt
I ran the robots.txt through a syntax checking tool (http://www.sxw.org.uk/computing/robots/check.html) This is what the tool came back with: http://www.dcs.ed.ac.uk/cgi/sxw/parserobots.pl?site=plasticplace.com There seems to be many errors on the file.
Additionally, I looked at our robots.txt in the WMT and they said the crawl was postponed because the robots.txt is inaccessible. What does that mean?
A few questions:
1. Is there a need for all the lines of code that have the “#” before it? I don’t think it’s necessary but correct me if I'm wrong.
2. Furthermore, why are we blocking so many things on our website? The robots can’t get past anything that requires a password to access anyhow but again correct me if I'm wrong.
3. Is there a reason Why can't it just look like this:
User-agent: *
Disallow: /onepagecheckout/
Disallow: /checkout/cart/
I do understand that Magento has certain folders that you don't want crawled, but is this necessary and why are there so many errors?

Yes your short robots.txt idea would create a huge problem.
In your Magento admin if you click in the menu Catalog > URL Rewrite Management
You will see the magento feature that creates all the "pretty urls", in that page you will see a table. If get value from Target path column and copy and paste after your site domain, for example domain.com/value_in_target_path...
You'll see that the page loads fine, you don't want Google to rank those pages with the "messy" URL so that's why you need all those stuff in your robots.txt
-
I am bit confused. Are you saying that technically my Magento site has two different urls that can both be indexed; one with a (messy) url and another with a vanity url? This would create major duplicate content issues! The robots.txt would not solve such a complex issue.
Am I missing something?
-
My developer said they custom configured it to block the files they needed according to Magento.
You think I can simply make it look like this:
User-agent: *
Disallow: /onepagecheckout/
Disallow: /checkout/cart/
and then disable it in WMT?

3. Is there a reason Why can't it just look like this:
Yes, It would generate a lot of duplicates issues, for example your robots.txt you have the follow line:
Disallow: /catalog/category/view/ -> That's the "real" category URL, you can access any category on magento by /catalog/category/view/id or by the "pretty" URL. Because you disallow the "real: URL only the pretty URL will be viable for search engines. This same rule apply for many other parts of the robots.txt.
-
I assume this is a robots.txt that has been automatically created by Magento? - or has it been created by a developer?
I ran it through a tool and it showed 1 error and 10 warnings - so i would say you definitely need to do something about it.
The reason for all those disallows is to try and stop search engine indexing them (whether they would even find them to index them if they were not there is debatable).
What you could do is set up robots.txt as you have suggested and then stop the SE's indexing the directories or pages you don't want in appropriate webmaster tools.
I don't like displaying a lot of 'don't index' paths in the robots texts as it is pretty much telling any hacker or nasty spider where your weak points may be.

Should I block robots from URLs containing query strings?
I'm about to block off all URLs that have a query string using robots.txt. They're mostly URLs with coremetrics tags and other referrer info. I figured that search engines don't need to see these as they're always better off with the original URL. Might there be any downside to this that I need to consider? Appreciate your help / experiences on this one. Thanks Jenni

Question about Robot.txt
I just started my own e-commerce website and I hosted it to one of the popular e-commerce platform Pinnacle Cart. It has a lot of functions like, page sorting, mobile website, etc. After adjusting the URL parameters in Google webmaster last 3 weeks ago, I still get the same duplicate errors on meta titles and descriptions based from Google Crawl and SEOMOZ crawl. I am not sure if I made a mistake of choosing pinnacle cart because it is not that flexible in terms of editing the core website pages. There is now way to adjust the canonical, to insert robot.txt on every pages etc. however it has a function to submit just one page of robot.txt. and edit the .htcaccess. The website pages is in PHP format. For example this URL: www.mycompany.com has a duplicate title and description with www.mycompany.com/site-map.html (there is no way of editing the title and description of my sitemap) Another error is www.mycompany.com has a duplicate title and description with http://www.mycompany.com/brands?url=brands Is it possible to exclude those website with "url=" and my "sitemap.html" in the robot.txt? or the URL parameters from Google is enough and it just takes a lot of time. Can somebody help me on the format of Robot.txt. Please? thanks

Robots.txt Showing in SERP Results
Currently doing a technical audit for a website and when I search "Site:website.com -www" the only result is website.com/robots.txt I was wondering if anyone else has come across this before -- or what this may mean from a technical audit standpoint. Thank you!

How to allow one directory in robots.txt
Hello, is there a way to allow a certain child directory in robots.txt but keep all others blocked? For instance, we've got external links pointing to /user/password/, but we're blocking everything under /user/. And there are too many /user/somethings/ to just block every one BUT /user/password/. I hope that makes sense... Thanks!

OK to block /js/ folder using robots.txt?
I know Matt Cutts suggestions we allow bots to crawl css and javascript folders (http://www.youtube.com/watch?v=PNEipHjsEPU) But what if you have lots and lots of JS and you dont want to waste precious crawl resources? Also, as we update and improve the javascript on our site, we iterate the version number ?v=1.1... 1.2... 1.3... etc. And the legacy versions show up in Google Webmaster Tools as 404s. For example: http://www.discoverafrica.com/js/global_functions.js?v=1.1

http://www.discoverafrica.com/js/global.js?v=1.2
http://www.discoverafrica.com/js/jquery.validate.min.js?v=1.1
http://www.discoverafrica.com/js/json2.js?v=1.1 Wouldn't it just be easier to prevent Googlebot from crawling the js folder altogether? Isn't that what robots.txt was made for? Just to be clear - we are NOT doing any sneaky redirects or other dodgy javascript hacks. We're just trying to power our content and UX elegantly with javascript. What do you guys say: Obey Matt? Or run the javascript gauntlet?0 -
Robots exclusion
Hi All, I have an issue whereby print versions of my articles are being flagged up as "duplicate" content / page titles. In order to get around this, I feel that the easiest way is to just add them to my robots.txt document with a disallow. Here is my URL make up: Normal article: www.mysite.com/displayarticle=12345 Print version of my article www.mysite.com/displayarticle=12345&printversion=yes I know that having dynamic parameters in my URL is not best practise to say the least, but I'm stuck with this for the time being... My question is, how do I add just the print versions of articles to my robots file without disallowing articles too? Can I just add the parameter to the document like so? Disallow: &printversion=yes I also know that I can do add a meta noindex, nofollow tag into the head of my print versions, but I feel a robots.txt disallow will be somewhat easier... Many thanks in advance. Matt

Robots.txt blocking site or not?
Here is the robots.txt from a client site. Am I reading this right --
Technical SEO | | 540SEO
that the robots.txt is saying to ignore the entire site, but the
#'s are saying to ignore the robots.txt command? See http://www.robotstxt.org/wc/norobots.html for documentation on how to use the robots.txt file To ban all spiders from the entire site uncomment the next two lines: User-Agent: * Disallow: /0 -
Robots.txt Syntax
Does the order of the robots.txt syntax matter in SEO? For example (are there potential problems with this format): User-agent: * Sitemap: Disallow: /form.htm Allow: / Disallow: /cgnet_directory
