Webmaster Forum / HTML, CSS, Scripts / JavaScript / July 2007How do I hide javascript content from googlebot?
I have a piece of code that I'd rather google's spider did not follow. Is this possible please?

Sorry, you're right. I have a bit of javascript code that I dont want to google to index. Is there a Javascript method to hide this code from the crawler?

You could test for the word "googlebot" with serverside jscriptin Request.ServerVariables("HTTP_USER_AGENT"), but I doubt Google will ever visit your site, if they find out. Anyhow, why would you want to do that? Is your scripting so unique and valuable, that anyone would be interested? If so, use serverside techniques, which codes are hidden by default.

Ah yes! Good thinkin - I'll do it with PHP.

You shouldn't do that. The Robots Exclusion Protocol contains widely accepted rules how to keep crawlers away from your website, or from some parts of it. Just create a file named "robots.txt" in your website's root directory. This "robots.txt"-file keeps all robots out of .js files: User-agent: * Disallow: /*.js$ This "robots.txt"-file tells (only) Google to stay away from directory /javascript/: User-agent: Googlebot Disallow: /javascript/ Information: http://en.wikipedia.org/wiki/Robots_Exclusion_Standard http://www.google.com/support/webmasters/bin/answer.py?answer=33570 -- Bart Bart Van der Donck wrote on 29 jul 2007 in comp.lang.javascript: >>> I have a piece of code that I'd rather google's spider did >>> not follow.

Ever visit his site when you are Google? I think it's better to use robots.txt rather than reading out the UA, and then decide to (whether or not) output javascript code based on that info. The general goal is not clear for me. Crawlers don't do much with javascript; at best they may detect some hyperlinks to index them. So what's the use of hiding js code for crawlers ? Preventing the code to be displayed in search results ? I'ld say a well-programmed crawler wouldn't do that. Preventing source code to influence algorithms like PageRank ? > My interpretation of "a piece of code" is inHTML code, > not a complete .js file. When I read the orignal poster's sentence "I have a piece of code that I'd rather google's spider did not follow", I surmised he meant a a separate .js file, because that's the only thing a bot could follow. -- Bart >> Bart Van der Donck wrote on 29 jul 2007 in comp.lang.javascript: >> [quoted text clipped - 29 lines] > -- > Bart Hi guys, I've already sorted this out using PHP but to clarify: I have a JS link that records votes on my site. googlebot was clicking it and voting over and over so I wanted to hide it. Now hold that thought! I know I shouldn't be doing stuff like that with javascript but I did it years ago when I didnt really know what I was doing. It's not a big important project and I'm far to lazy to go back and change the whole system now. Thanks for the help! Ciarán |
