title: Do search engines process Javascript?
body: <p>According to <a href="http://www.websiteceo.com/articles/js-indexing.htm" rel="noreferrer">this page</a> it would seem like they don't, in the sense that they don't actually run it, but that page is 2 years old (judging from the copyright info).</p>
  
  <p>The reason I'm asking this question is because we use Javascript to replace text on our site with other more typographically sound content. We're worried that this may affect the crawlability/seo of our sites, since generally what we're replacing is headers; ie. <code>&lt;h1&gt;</code>, <code>&lt;h2&gt;</code>, etc.</p>
  
  <p>Will search engine bots see our original code, or will they run the Javascript and see the replaced text?</p>
