I am doing some market research, and aim to create several landing pages aimed at long tail searches.
Do these landing pages need to be in the navigation, or have an incoming link from somewhere else on the website, in order to be included in Google's index?
I don't want to include them in the navigation, because some of the landing pages will be addressing similar search terms, and they will look silly being listed next to each other if they are so similar.
Likewise, I don't want to necessarily use a Sitemap page, which links to the landing pages. I don't want a website visitor know I use a variety of landing pages to entice traffic.
So, is it possible for isolated, stand alone webpages to be included in the Google index?
