Do be aware the likes and shares are not pages view stats. Likes and shares are misleading when you are talking about page view stats. Your followers and anyone with a WordPress.com blog who is logged into WordPress.com can “like” and “share” your posts in several locations such as in email and the Reader without ever clicking into your blog and creating a page view stat.
You can control the length of the entry sent out on your RSS feed here > Settings > Reading
and choose the “summary” setting for your RSS feed or the “full text”. If you set it to summary then visitors have to click into the blog to read the full post.
