Can I use JavaScript?

JavaScript can make your web page look fantastic, but an excessive use of JavaScript often hinders a search engine spider. This in turn lowers your chances of being indexed by the search engines. In fact, excessive use of JavaScript is the most common reason why web pages are not indexed. Furthermore, if your URLs are embedded in JavaScript, most search engines will neither recognize them nor Index them pages at all.

If you are serious about getting your pages indexed by the search engines and wish to obtain a good position on the MAJOR search engines such as  Google, MSN Search, AltaVista, Yahoo in addition to many others, you must consider changing your website. You can achieve this by either placing the links on your pages in simple HTML format or by including alternative links at the bottom of your pages, just for the search engines to spider and navigate through.

There shouldn't be any serious problems in using JavaScript on your page. There are indeed many important advantages to incorporating it into your site; just don't overdo it. Try to keep your page as simple as possible when it comes to HTML and try to use more tables, fewer images, and use JavaScript only where it is necessary. Constructing an entire page with JavaScript can make it almost invisible to most major search engines these days. Moreover, it's better to put your JavaScripts into an external .js file and hide them from search engine spiders by placing them in a Directory that is protected by a Robot text file.

This is an example of an external javascript. Set this in the head section of your html code:

<Script type="text/javascript" src="http://www.domain.com/javascript.js">script>
