SEO Tip: Don’t Use Too Much JavaScript

Searchbots are not designed to read, follow or index JavaScript code. If your website contains a few lines of text in the JavaScript code, chances are the searchbots will ignore the entire block of code along with your text.

JavaScript menus are the same as Flash menus; unreadable. The search engines will not follow your page links. It is best to avoid JavaScript menus entirely. If you feel you must have the multi-tier drop-downs, provide HTML text links in the footer or in the content of your home page. Some of the AJAX menu and billboard slideshow code now includes unordered lists of HTML links, and is advertised as being ‘search engine friendly’. If the links appear within JavaScript those lists are almost certainly being ignored by the searchbots.

Try to keep the use of JavaScript to a minimum. If the use of JavaScript is unavoidable consider creating an external JavaScript file and link to it.
