Dropdown menu forms being followed by Googlebot

Is it passing PR?

[Nostalgic Dave]

Hello all... I just added 2 drop-down menus to the main page of my website, and right away I noticed that Googlebot was following the menu items. I didn't think it could do this. So now I am worried... is my PR being passed too? I don't want to waste any of my precious PR! If it is being passed, how can I (or should I?) prevent it?

It all depends on the technology you're using -- how those links in the dropdown are coded. But I wouldn't be too concerned about "wasting" PR. A page's PR is not diminished by voting PR to another page. What can happen is that the total "PR vote" is split into more parts, so then each vote counts a bit less towards each link's target url.

Tedster, my main page has a PR of 4 and I had a problem with many of my pages falling into supplemental. I was able to get many of my important pages out of supplemental by reducing the number of links on the main page. Now I fear that these new drop-downs will spread the PR too thin over too many links from the main page and I'll be back in the poor house.

Here is what I am doing in HTML:

<form name="form1" method="get" action="http://www.sample.com/index.asp">
<select name="pulldown1" onchange="this.form.submit()">
<option value="choice1" selected>choice1</option>
<option value="choice2">choice2</option>
</select>
<input type="submit" value="Submit">
</form>

If Googlebot followed the links, I am just assuming that they could as easily pass PR, but... do they with this way of coding? Any recommendations on how to do it in a non-PR-passing way without violating any of G's rules?

Advice is appreciated as always.

Thanks
