[Zope] Indexing by search engine

I've got a zope site at myzopeserver:portnumber/mysite the url www.mysite.com is rerouted by Apache to zoperoot/mysite if i enter www.mysite.com in my webbrowser zope renders the index_html inside mysite. That's fine, however if i submit my site to a search engine the search engine indexes the folder's (mysite is the folder) title! my index_html has al necessary tags, i.e. title, meta tags etc. so somehow the search engine doesn't render my index page whereas my browser does. í am now using a dtml method as index_html, could this be the problem? or is there something else wrong here?
