We'll create fresh WordPress site with LinkedIn Perfect Share installed. You have 20 minutes to test the plugin after that site we'll be deleted.
LinkedIn Perfect Share detects when LinkedIn is parsing/crawling the Open Graph tags of a post/page and provides a simplified version of the contents. This allows the scraper to see the correct sharing post’s data for the provided URL; the information includes the post title, the description and the Featured Image (that is the standard content for the WordPress’ og:image field).
