what is not recommended in SEO ?

Search engines perform several activities in order to deliver search results:

Flash and shockwave-spiders do not pick up these files. 

Image only sites - spiders do not pick up images 

Image maps -spiders cannot read image maps.Do not use them on your home page or critical pages. 

Frames -only one page can be titled (titling is critical in search rankings). If the spider cannot read the complete page (because of the frames), it will not be indexed properly. Some spiders may not even read a frames web site 

Password protected pages-spiders cannot enter password protected pages 

PDF files-can be problematic for spiders. Although some search engines can index them, the pages must be interpreted into HTML and can lose much of their content. place PDFs lower down in your site 

Dynamic pages-spiders cannot index some content on pages using ASP, CGI or other dynamic languages.Make sure important pages are HTML, no dynamically generated content. 

Drop down menus -spiders cannot read them
