Best Practices for Publishers: Save Users Time
Lunes, 10 de Septiembre de 2012 08:42

Fast Load Times

At what point during page load are you displaying your social tools? Provide your users with a quick page launch by loading your social widget at the end. This prevents long wait periods and keeps your users happy and engaged with your content. To ensure that your content always load first, the ShareThis widget code defaults to this setting. In addition, there is an option to load the ShareThis widget at the very end, after all your ads, plugins and data intensive elements have loaded.


Multi-Post Sign In

Users often share to multiple social channels. Provide the sign-in options that work best for your site. Using Open Authorization allows users to share to multiple social channels at the same time without having to leave your site. ShareThis publishers, such as 
The Daily Beast, employ this sign-in option on their site.

I hope the Best Practices for Publishers series was helpful and informative. Again, here is a recap of what you’ve learned.

Increase Social Engagement on your site.
1. Use the right social tool Form Factor for your website
2. Place buttons in locations where users can easily share your content.
