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.

What do you do with product pages that are no longer used ? Delete/redirect to category/404 etc
We have a store with thousands of active items and thousands of sold items. Each product is unique so only one of each. All products are pinned and pushed online ... and then they sell and we have a product page for a sold item. All products are keyword researched and often can rank well for longtail keywords Would you :- 1. delete the page and let it 404 (we will get thousands) 2. See if the page has a decent PA, incoming links and traffic and if so redirect to a RELEVANT category page ? ~(again there will be thousands) 3. Re use the page for another product - for example a sold ruby ring gets replaces with ta new ruby ring and we use that same page /url for the new item. Gemma

Robots txt. in page with 301 redirect
We currently have a a series of help pages that we would like to disallow from our robots txt. The thing is that these help pages are located in our old website, which now has a 301 redirect to current site. Which is the proper way to go around? 1- Add the pages we want to disallow to the robots.txt of the new website? 2- Break the redirect momentarily and add the pages to the robots.txt of the old one? Thanks

2 sitemaps on my robots.txt?
Hi, I thought that I just could link one sitemap from my site's robots.txt but... I may be wrong. So, I need to confirm if this kind of implementation is right or wrong: robots.txt for Magento Community and Enterprise ...

Would using javascript onclick functions to override href target be ok?
Hi all, I am currently working on a new search facility for me ecommerce site... it has very quickly dawned on me that this new facility is far better than my standard product pages - from a user point of view - i.e lots of product attributes for customers to find what they need faster, ability to compare products etc... All in all just better. BUT NO SEO VALUE!!! i want to use this search facility instead of my category/product pages... however as they are search pages i have "robots noindex them" and dont think its wise to change that... I have spoken to the developers of this software and they suggested i could use some javascript in the navigation to change the onlclick function to take the user to the search equivelant of the page... They said this way my normal pages are the ones that are still indexed by google etc, but the user has the benefit of using the improved search pages... This sounds perfect, however it also sounds a little deceptive... and i know google has loads of rules about these kinds of things, the last thing i want is to get any kind of penalty or any negative reaction from an SEO point of view... I am only considering this as it will improve the user experience on my website... Can any one advise if this is OK, or a "no no"... P.s for those wondering i use an "off the shelf" cart system and it would cost me an arm and a leg to have these features built into my actual category / product pages.

Oh no googlebot can not access my robots.txt file
I just receive a n error message from google webmaster Wonder it was something to do with Yoast plugin. Could somebody help me with troubleshooting this? Here's original message Over the last 24 hours, Googlebot encountered 189 errors while attempting to access your robots.txt. To ensure that we didn't crawl any pages listed in that file, we postponed our crawl. Your site's overall robots.txt error rate is 100.0%. Recommended action If the site error rate is 100%: Using a web browser, attempt to access http://www.soobumimphotography.com//robots.txt. If you are able to access it from your browser, then your site may be configured to deny access to googlebot. Check the configuration of your firewall and site to ensure that you are not denying access to googlebot. If your robots.txt is a static page, verify that your web service has proper permissions to access the file. If your robots.txt is dynamically generated, verify that the scripts that generate the robots.txt are properly configured and have permission to run. Check the logs for your website to see if your scripts are failing, and if so attempt to diagnose the cause of the failure. If the site error rate is less than 100%: Using Webmaster Tools, find a day with a high error rate and examine the logs for your web server for that day. Look for errors accessing robots.txt in the logs for that day and fix the causes of those errors. The most likely explanation is that your site is overloaded. Contact your hosting provider and discuss reconfiguring your web server or adding more resources to your website. After you think you've fixed the problem, use Fetch as Google to fetch http://www.soobumimphotography.com//robots.txt to verify that Googlebot can properly access your site.

Redirecting blog.<mydomain>.com to www.<mydomain>.com\blog</mydomain></mydomain>
This is more of a technical question than pure SEO per se, but I am guessing that some folks here may have covered this and so I would appreciate any questions. I am moving from a WordPress.com-based blog (hosted on WordPress) to a WordPress installation on my own server (as suggested by folks in another thread here). As part of this I want to move from the format blog.<mydomain>.com to www.mydomain.com\blog. I have installed WordPress on my server and have imported posts from the hosted site to my own server. How should I manage the transition from first format to the second? I have a bunch of links on Facebook, etc that refer to URLs of the blog..com format so it's important that I redirect.</mydomain> I am running DotNetNuke/WordPress on my own IIS/ASP.Net servers. Thanks. Mark
