Login and Other User Entry Form Pages
If your site requires user registration before it will display content, I have news for you – it won't be indexed by the search engine spiders.
Spiders do not submit forms, so any content that requires a login or asks the user to enter a country before showing a page will not be indexed.
JavaScript
JavaScript is a scripting language originally developed by Netscape for use within HTML web pages – JavaScript and Java are not related. Overall, the search engine spiders do not execute JavaScript. If your site has a JavaScript menu system, the spiders will ignore it. There are workarounds to this issue. You can provide an alternative navigation system, hard coded in HTML, and use standard anchor tags to enable the search engine spiders to index your site.
Flash Sites
Flash is a graphics animation program that uses vector graphics. Flash files occur most commonly in animated advertisements on web pages and rich-media web sites.
Search engine spiders have limited ability to read Flash. They can decipher some of the content but, as a general rule of thumb, you should assume that the search engines ignore Flash.
If your menu system is in Flash, provide a secondary HTML menu system.
If your site’s content is in Flash, provide HTML versions of the page for the spiders to index.
Both of these tactics will help users who have Flash turned off on their browser, including users who can't run Flash and visually impaired visitors who use screen reading software.
