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/jquery.cookie.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=1.1Wouldn'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?

Hey!
So, I listened to Matt's video. I see his point about wanting to crawl the JS files just in case something tricky is going on. Do understand that this is a risk you take. I don't see an issue blocking crawling of those files from a logical perspective, but if you or someone that takes over for you in the future does do something sneaky with JS and you are caught ... plus you have blacked access to the offending files ... it is going to take a lot more work to get back in good graces with them.
It's like a cop searching your car. You have every right to ban them from doing so, but if you have nothing to hide, why make trouble? Matt is right, banning crawling of these files is not going to save you much but if you think it's an issue, feel free. Just know that they might take it as a possible flag in the future.

Harald, it looks like the response you've quoted is from http://groups.google.com/a/googleproductforums.com/forum/#!category-topic/webmasters/crawling-indexing--ranking/9MGYEoROdkg, which is a question about a menu that has javascript. I think this poster has a slightly different question. I'll ask another associate to come on in and take a look.

Hi Discover,I think that whenever we access the web pages , we have seen number of times that there is run time error & they asking for debug. This error message is helpful for the developers only but not for the users.
I think that you should please refer to the following link:
The truth about non javascript
I hope that above content help to solve your query.

One robots.txt file for multiple sites?
I have 2 sites hosted with Blue Host and was told to put the robots.txt in the root folder and just use the one robots.txt for both sites. Is this right? It seems wrong. I want to block certain things on one site. Thanks for the help, Rena

Blocking Affiliate Links via robots.txt
Hi, I work with a client who has a large affiliate network pointing to their domain which is a large part of their inbound marketing strategy. All of these links point to a subdomain of affiliates.example.com, which then redirects the links through a 301 redirect to the relevant target page for the link. These links have been showing up in Webmaster Tools as top linking domains and also in the latest downloaded links reports. To follow guidelines and ensure that these links aren't counted by Google for either positive or negative impact on the site, we have added a block on the robots.txt of the affiliates.example.com subdomain, blocking search engines from crawling the full subddomain. The robots.txt file is the following code: User-agent: * Disallow: / We have authenticated the subdomain with Google Webmaster Tools and made certain that Google can reach and read the robots.txt file. We know they are being blocked from reading the affiliates subdomain. However, we added this affiliates subdomain block a few weeks ago to the robots.txt, but links are still showing up in the latest downloads report as first being discovered after we added the block. It's been a few weeks already, and we want to make sure that the block was implemented properly and that these links aren't being used to negatively impact the site. Any suggestions or clarification would be helpful - if the subdomain is being blocked for the search engines, why are the search engines following the links and reporting them in the www.example.com subdomain GWMT account as latest links. And if the block is implemented properly, will the total number of links pointing to our site as reported in the links to your site section be reduced, or does this not have an impact on that figure?From a development standpoint, it's a much easier fix for us to adjust the robots.txt file than to change the affiliate linking connection from a 301 to a 302, which is why we decided to go with this option.Any help you can offer will be greatly appreciated.Thanks,Mark

Can you have a /sitemap.xml and /sitemap.html on the same site?
Thanks in advance for any responses; we really appreciate the expertise of the SEOmoz community! My question: Since the file extensions are different, can a site have both a /sitemap.xml and /sitemap.html both siting at the root domain? For example, we've already put the html sitemap in place here: https://www.pioneermilitaryloans.com/sitemap Now, we're considering adding an XML sitemap. I know standard practice is to load it at the root (www.example.com/sitemap.xml), but am wondering if this will cause conflicts. I've been unable to find this topic addressed anywhere, or any real-life examples of sites currently doing this. What do you think?

Using Sitemap Generator - Good/Bad?
Hi all I recently purchased the full licence of XML Sitemap Generator (http://www.xml-sitemaps.com/standalone-google-sitemap-generator.html) but have yet used it. The idea behind this is that I can deploy the package on each large e-commerce website I build and the sitemap will be generated as often as I set it be and the search engines will also be pinged automatically to inform them of the update. No more manual XML sitemap creation for me! Now it sounds great but I do not know enough about pinging search engines with XML sitemap updates on a regular basis and if this is a good or bad thing? Can it have any detrimental effect when the sitemap is changing (potentially) every day with new URLs for products being added to the site? Any thoughts or optinions would be greatly appreciated.

Subdomain Removal in Robots.txt with Conditional Logic??
I would like to see if there is a way to add conditional logic to the robots.txt file so that when we push from DEV to PRODUCTION and the robots.txt file is pushed, we don't have to remember to NOT push the robots.txt file OR edit it when it goes live. My specific situation is this: I have www.website.com, dev.website.com and new.website.com and somehow google has indexed the DEV.website.com and NEW.website.com and I'd like these to be removed from google's index as they are causing duplicate content. Should I: a) add 2 new GWT entries for DEV.website.com and NEW.website.com and VERIFY ownership - if I do this, then when the files are pushed to LIVE won't the files contain the VERIFY META CODE for the DEV version even though it's now LIVE? (hope that makes sense) b) write a robots.txt file that specifies "DISALLOW: DEV.website.com/" is that possible? I have only seen examples of DISALLOW with a "/" in the beginning... Hope this makes sense, can really use the help! I'm on a Windows Server 2008 box running ColdFusion websites.

Is using a Href in Div OK?
Hi, I was just wondering what your thoughts are on using a Href in a Div, which contains anchor text. We currently use the Href on the div, as opposed to just the anchor text as I want the whole div to be clickable as opposed to just the anchor text. So currently I have: Keword 1
