    JavaScript isn't good neither bad for SEO. It's just that search engines like Google and their crawlers/spiders are not able to easily crawl/read the coding/script.

    But that doesn't mean you can't use it on your website. You can use a tiny fraction of JavaScript where needed but make sure the JavaScript coding you are using is clean.

    Hope this helps.

    I don't know why this myth continues to be perpetuated by so many people. Google has been indexing pages that are only linked to via Ajax/JavaScript for years now (at least since early 2008).
    Obviously, doing stupid things with JavaScript will harm your SEO efforts. In the same way an idiot has the potential to harm himself with a pointy stick.

    This is not a binary question, it isn't a yes or no answer. Use your common sense and don't be a fool with it, and you'll do well :).

    if your site has thousands visitors a day ,and a lot of back links ,no matter how many javascript you use ,Google will index you fast .

    With that said, Google has been indexing pages or links under the influence of Ajax/JavaScript however there is still another form of java scripting that is still not sure that Googlebots will be able to crawl.

    If you have a URL in the markup, contained in javascript

    
       <a href="#" onclick="window.open('somewebsite, 'currentWindow')">
       Link Text
       </a>
    
    Code (markup):
    Then Googlebots can see the markup and the javascript, and possibly understand the URL.

    If you use something like doc.write

    
       <script type="text/javascript">
          document.write('<a href="www.domain.com" ">Link Text<\/a>');
       </script>
    
    Code (markup):
    Then I don't think Googlebot will see this information.

    Using JavaScript is not really bad for SEO however, if done in the wrong way can obviously get you in trouble.

    You can use Javascript code, but use it below your content or I would recommended not to use.

    IT is not good because user agents like . googlebots do not recognize it. it is better to use javascript or css as a external file then call on your page.

    Are you even reading this thread? Javascript has been crawlable by Googlebots since late 2008. However on my post, I am still unsure that if you use doc.write on your javascript will still be crawlable for Googlebots.

    Java script is not SEO friendly because search engine crawler prefer simple script & W3C validated code for crawling. So not use Java script if it is not necessary.

    I have no doubt that googlebot can also read document.write()'s. What would make them so invisible? in fact - they would probably be easier to read... just grab what ever text string is evaluated between the braces and hey presto!

    I just found another post on webmaster world from 2006 where they found googlebot was following some of their javascript links, that's four years! Google has the best software engineers in the world, I think they could figure out how to make their crawler read javascript if they could make Chrome read it as fast as it does :).

    Also, check out some of SEOMoz's experiments - they caught it reading some pretty complex javascript involving string manipulation and JQuery, and it still managed to get the URL. Hell, check out my personal website! I have a dynamic quote, pulled in through Ajax using JQuery and google has index EVERY single quote from my site.

    Moral of the story: do what's good for the user and google will find it. If you have an entire javascript/ajax based interface where you can't even bookmark certain sections of the site - then users are going to get pissed off and google won't like you. Keep it lightweight, fast and simple.

    Some times you can say java script is good for Seo because with the help of java script you can puts a validation on our query forms and users are understands to easy way what is mistake for me.

    Well that's him and the rest of DP noobs who don't even read the thread and they'll just post something which is untrue. These noobs really need educating! lol. As for the javascript, I wouldn't be surprised what Google can index in the near future, they're also starting to index flash! Now that is really something!

    Agreed! what really has me stunned is how they tell pornographic images from everything else. They have a method of measuring the hues in the picture, if too many are fleshy coloured then they assume it's a pornographic picture and flag it to show only when the moderation filter is off. This works with a 90%+ accuracy. I've lost the link to the paper about this, if anybody finds it - please post! :)
