I&#x27;m curious how google strongly penalizes SPAs for being slow to load.<p>The content may be indexed, but if your visitors are on a mobile network, that initial visit (or a visit with stale cache) is going to be crappy. It&#x27;s great that they can read in they content (though bing cannot), but if it&#x27;s buried on page two, does it even matter?<p>As someone who is a proponent of web perf, these kind of articles make me worried that server side rendering will be ignored because &quot;SEO works now for Javascript&quot;, even if it&#x27;s slow and google is only 70% desktop &amp; 80% mobile search.
