Does drop down menu effect seo

I have about 1000 areas on the home page from a drop down form, does this effect seo or
dilute my keyword for the page. Thanks

Well, it will definitely spread your pr around.

 

I do not think it could cause your PR diluted. Those are just drop down option and not a link, not even an internal linking.

 

What about the keyword density of the page. 200 word of text and 1000 of text in the drop down which shows in the spider.

 

It is better to use less menu bars but they should be more precise, I think. Such a large massive of information can cause informational overload of your visitors, they can become confused and then won't make their choice.
