are the links that show on the drop down menu on a homepage, counted as "first click" pages or "2nd click"? (I mean those menu items that show only when you press on a visible menu item)
If your drop down menu is made with CSS and not javascript or flash then yes because the search engines see it is a long list of links and not broken into categories. Take your site, turn off CSS and you can get an idea as to how the spiders see your website. You can also use a text browser like Lynx to look at your site.
I second that. Javascripts or flash can't be crawled by the search engines. And I guess making your site in CSS format is one advise that should be considered with regards to the proper search engine friendly design layouts.
java script will not crawl but any how after clicking page will go to the url, so google will crawl that URL
