Did you know, by default, your new WordPress installation is not visible to the search engines? Yep it’s true!
Until you check the box under > settings > privacy, changing it from:
“I would like to block search engines, but allow normal visitors”
“I would like my blog to be visible to everyone, including search engines (like Google, Bing, Technorati) and archivers”,
all of your blog pages, posts and links are nofollowed.
Which means Google and most of the other search engines will never find them.
