Use of JavaScript or Other Unspiderable Code
If your website includes JavaScript code or other codes that prevent the Search Engines Bot's from spidering or blocking them from reading your pages then you are limiting you acceptance and indexing by the search engines such as Google, Yahoo, MSN of all of your pages and content.
If you must use JavaScript try to use it sparingly or preferably not at all. Search Engines cannot read JavaScript and it is therefore impossible for them to effectively 'Read' your pages and in many cases it acts like a locked door to block a path to further pages on your site.
!If you really want to use JavaScript you can safely use it by putting the code into a separate JS file and you can load it into the page with a single line of code between your – <head> and </head> tags within your web page.
The code used within your <head> section should look like:
<script language="javascript" type="text/javascript" src="replace-with-JavaScript-file-name.js"></script>
