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.

Sudden Indexation of "Index of /wp-content/uploads/"
Hi all, I have suddenly noticed a massive jump in indexed pages. After performing a "site:" search, it was revealed that the sudden jump was due to the indexation of many pages beginning with the serp title "Index of /wp-content/uploads/" for many uploaded pieces of content & plugins. This has appeared approximately one month after switching to https. I have also noticed a decline in Bing rankings. Does anyone know what is causing/how to fix this? To be clear, these pages are **not **normal /wp-content/uploads/ but rather "index of" pages, being included in Google. Thank you.

Robots.txt in subfolders and hreflang issues
A client recently rolled out their UK business to the US. They decided to deploy with 2 WordPress installations: UK site - https://www.clientname.com/uk/ - robots.txt location: UK site - https://www.clientname.com/uk/robots.txt
Technical SEO | | lauralou82
US site - https://www.clientname.com/us/ - robots.txt location: UK site - https://www.clientname.com/us/robots.txt We've had various issues with /us/ pages being indexed in Google UK, and /uk/ pages being indexed in Google US. They have the following hreflang tags across all pages: We changed the x-default page to .com 2 weeks ago (we've tried both /uk/ and /us/ previously). Search Console says there are no hreflang tags at all. Additionally, we have a robots.txt file on each site which has a link to the corresponding sitemap files, but when viewing the robots.txt tester on Search Console, each property shows the robots.txt file for https://www.clientname.com only, even though when you actually navigate to this URL (https://www.clientname.com/robots.txt) you’ll get redirected to either https://www.clientname.com/uk/robots.txt or https://www.clientname.com/us/robots.txt depending on your location. Any suggestions how we can remove UK listings from Google US and vice versa?0 -

Url folder structure
I work for a travel site and we have pages for properties in destinations and am trying to decide how best to organize the URLs basically we have our main domain, resort pages and we'll also have articles about each resort so the URL structure will actually get longer:
Technical SEO | | Vacatia_SEO
A. domain.com/main-keyword/state/city-region/resort-name
_ domain.com/family-condo-for-rent/orlando-florida/liki-tiki-village_ _ domain.com/main-keyword-in-state-city/resort-name-feature _
_ domain.com/family-condo-for-rent/orlando-florida/liki-tiki-village/kid-friend-pool_ B. Another way to structure would be to remove the location and keyword folders and combine. Note that some of the resort names are long and spaces are being replaced dynamically with dashes.
ex. domain.com/main-keyword-in-state-city/resort-name
_ domain.com/family-condo-for-rent-in-orlando-florida/liki-tiki-village_ _ domain.com/main-keyword-in-state-city/resort-name-feature_
_ domain.com/family-condo-for-rent-in-orlando-florida/liki-tiki-village-kid-friend-pool_ Question: is that too many folders or should i combine or break up? What would you do with this? Trying to avoid too many dashes.0 -

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

Google Off/On Tags
I came across this article about telling google not to crawl a portion of a webpage, but I never hear anyone in the SEO community talk about them. http://perishablepress.com/press/2009/08/23/tell-google-to-not-index-certain-parts-of-your-page/ Does anyone use these and find them to be effective? If not, how do you suggest noindexing/canonicalizing a portion of a page to avoid duplicate content that shows up on multiple pages?
