All sharing is effective, but LinkedIn takes the CTR prize
Sharing via Facebook and Twitter nearly doubles email CTR rates—but the CTR leverage of sharing via LinkedIn is unmatched—even though the number of messages sent with LinkedIn sharing buttons plummeted 25% last year.
That drop merely "emphasizes the jump in effectiveness of the LinkedIn link," notes Hannah Andrzejewska, communication and marketing specialist for GetResponse. That's because at the same time "the CTR for emails that include [LinkedIn share buttons] has soared by almost 400%, making LinkedIn the top performer in CTR—that's a result worth fighting for," she points out.
