Actually they suffer from a number of wrong notions.
Many people believe that different search engines have different algorithms to determine the page ranking of a website and that is why the same page is not going to get better rankings in all the different search engines.
They also feel that the keyword rich page that they have created for search engines can't be put on the site where it could be accessed by visitors and certainly it can't be put on the front pages.
