Two "index" pages. Would this penalize?

Hello everybody:
I've just registered and this is my first post.
First thing I must say, before you realize it by your own in a minute, is that I'm a novice on optimization, the same on web design, and I don't speak english well. So, excuse me if my question has been answered before or if you can't understand me well.
My question is:
Could I make two "index pages", each one targeting different keywords, but both linking to the same pages of the site.
In my site, I'm thinking to make another page, with the main target keyword as the name of the page, and targeting different keywords than the actual index page. The links in that new page would point to the same pages the actual index page now points.
Say it would be two "entry" points to the site.
Is it bad?
If both pages where almost identical, would it be duplicate content?

The site I'm speaking:
http://www.telefonica.net/web2/sanabara/lyon

 

If they're *almost identical* then, yes. It's up to you to change the content of the pages to make sure this doesn't happen - if you're targeting different phrases then the content should be different anyway! Make sure both pages are linked up and I think it should be fine...

 

Make sure that your pages not only link to other areas of the site, but have links to them from other areas of the site. If you don't have links to and from a page, it can be viewed as a doorway page and a penalty could result. That's one of the problems I frequently see with splash pages.

 

I have a similar issue

I think the problem I had with my site is that dreamweaver saved my pages as
.htm

so I had index.htm for a long time before adding .html to my site
so most of my pages have two versions and I need to do more to make them different content wise

I did not want to delete them because so many linked to the .htm content

 

yes, that in SE's term is BAD. A well known directory recently did a 302 rewrite from domain.com to www .domain. com, and they got penalized. All these things matter.

Make sure u only either link to domain.com from everywhere or www .domain. com or www . domain.com/index.php, although they might all work the same. Spiders might index all 3 differently, which is NOT soooo good.
