Related Posts For showing up on front page from search engine but not directly

When I type in several of my clients site in say google and then click on the link to come to the main/home page of the website it shows “Related Posts For” or “We are planning to write more posts about “designerkitchensdirect com au” next week. Subscribe to the RSS feed for getting informed about it.” above all the text on the site, which should NOT be there at all.

But when I type in the site directly it does not show at all, which is what I want.

WP Version 2.6 one has “Your latest posts” selected and the other has static home page activated under Options -> Reading.

one site is:

http://www.designerkitchensdirect.com.au (when you do this you get the 2nd message) and when you type in designer kitchen direct you get the first message.

The other is (static home page selected under Options -> Reading):
Same happens with http://www.bspes.com or when you type in “Braithwaite Steiner Pretty” it produces different results.

Any light on this issue would be good..

Thanks
Carl
