Drop Down Link Box Issues

Issues a/b drop downs - link follow, crawlability, spam

[x3nos]

I use drop down menus like this:

<form name="formname">
<select name="url" onChange="if(options[selectedIndex].value) window.location.href=(options[selectedIndex].value)">
<option value="#">Option #1</option>
</select>
<input type="submit" value="go" name="submit">
</form>

Do the links get crawled in this type of "Jump Menu", does the text get craweld and does having several links across domains for a single client service constitute spam?

I have had several related sites from a single client that are implementing this type of cross linking and considering their true value, as I have a gut feeling they are doing nothing #1 and #2 are spam, if not in letter of the rules then at least in spirit.

Appreciate an open discussion on this type of issue.

I don't think those links will be followed by spiders. I've seen quite a few multi-site rings using that type of linking. I think they do it to avoid crosslinking penalties.

BirdMan - I am curious mostly about the optimization poss. of the drop downs, so if not link value do they carry keyword value? as in <option value="#">Widgets For Sale</option>. In other words would "Widgets" be counted against other references in the content of widgets and thereby increase keyword prominence?
