Google on toggled content

Question

I have optimized a website and have included toggled content. By toggled content I mean content that becomes visible after clicking a link (Expand and Collaps). The code is as followings:

<li id="article-1"> 
<h3><a href="" onClick="$('#article-1 p').not(':first').toggle(); return false;">Article title</a></h3> 
<p>First paragraph</p> 
<p>Second paragraph</p> 
<p>Third paragraph</p> 
</li>

Would Google consider this content less valuable since it is not 'directly' visible? Are there any key concepts to keep in mind when working with toggled content?

Answer 1

This content isn't special, good or bad, in any way. The only time hidden content becomes a problem is when it is hidden for sole purpose of manipulating the search results.

No.

Are there any key concepts to keep in mind when working with toggled content?

Yes, the main one is making sure your content can be indexed, which you're already concerned about. The secondary one is usability. You should put yourself in the position of someone using all types of browsers on various kinds of platforms, including mobile, and find out if that content is both visible and accessible to all the people you want to reach.
