I have a problem with google returning my index page as the search result for serach strings that should actually return an entry that has "fallen off" the page. Also, since the main index page is searched, combinations of words from different posts leads google to beleive that there is something on the page that there actually isn't.
A little bit of searching led me to This scribbling.net article on how to help the googlebot index better.
Whats given below suggests a remedy to my problem :
Webloggers: use the meta tags to help the Googlebot index only your permalinks, not your constantly changing front page. To do this, use
<meta name="robots" content="noindex,follow" >
on your front page and
<meta name="robots" content="index,follow" >
on your posts' permanent locations.
I looked at the index.php page, and I am not sure how to change the meta tag, when there are no parameters (the plain index.php) and for when a particular post is being displayed.
I would appreciate help and feedback with this problem.
