Splash pages, everywhere splash pages. Many people recommend to create a
splash or a squeeze page, but is that really necessary? There are two
sides of the medal. When you are using traffic exchanges to generate
page views, people have not much time when they surf to get through your
whole website and read all the text. A well designed splash page will
get attention and let people click to get more information.
On the other side, splash pages are not SEO friendly and search engines
like Google will not crawl your site because of less content on the
page. So using splash pages is okay in traffic exchanges but you should
still write good content for your own homepage. People will get directly to your website and to your content and what they don't want you see now is a splash page.
Use a splash or squeezepage where it makes sense and write good content to increase your Google ranking.
