You can also create it automatically Twitter cards for your pages, allows you to track the Twitter Analytics feature, embeds videos, and adds a button for tweets to posts from the manager's interface.
There is an option that allows you to configure the appearance of embedded tweets on your site to match the theme you use, along with a number of features that help users start advertising on Twitter (the latter does not work in Greece) .
You can download the Twitter plugin from official WordPress page.
