Do spiders crawl popups & drop down menus?

Hi guys :)

I was under the impression that spiders can't crawl JavaScript popups and drop down menus.

But when I recently looked in WMT, we have Duplicate Title Tag issues from popup and drop down URLs.

For example, on our site, you can choose how many results to view (10, 20, 30, etc.) via a drop-down menu. The URLs of these pages vary slightly but all have the same title tag. The only way of accessing the links is through the drop down menu.

Should I <META NAME="ROBOTS" CONTENT="NOINDEX, NOFOLLOW"> these pages to get rid of the duplicate title tag issue?

Any insight is really appreciated.

Thanks a ton!

Generally speaking, spiders can extract URLs and similar from javascript, which means that links in drop-down menus and similar can be spidered and indexed.

In addition, Googlebot has somewhat 'experimental' crawling of HTML forms [webmasterworld.com].

So, realistically, you have to consider content accessible via forms (javascript-based or not) to be spiderable, and if you don't want such content indexed, robots exclusion is the way to go. You could do this via a robots.txt file (typically utilising the major search engines' support for wildcard entries) or a meta tag is fine. If you think there are links from the pages that are worth spidering, you might consider noindex,follow.
