Do share buttons (facebook, stumbleupon, twitter, etc) incur a page-load penalty from Google? <p><strong>Our site saw traffic from Google drop significantly yesterday (only 5% traffic left in overnight)</strong>. I asked around. People say that site loading performance could caused the issue.</p> <p>I've looked at the performance. Site is loading in 1 or 2 seconds if no external links such as Google ads or share button. I cannot improve the Google Ads.</p> <p>For the share button, if you view the site <strong>Multiple Share buttons</strong> are loaded and it takes long time to load all of them. But, <strong>All of them are loaded in iframe</strong> (iframe page to different page but in same domain) to avoid slowing down page load.</p> <p>I think users are OK with this because all pages are loaded fast except the share buttons which come from each service site.</p> <p>But, my concern is that if <strong>Google care about all site loading including those in iframe</strong>, then it's big problem since it takes 10 seconds. If not, I will keep those share buttons.</p> <p><strong>Should I keep the share buttons or need to get rid of those?</strong> (I used addthis, it's super slow. And I added each buttons myself)</p>
