This may be old news to some of you. However, it was a new discovery for me this week.
At the beginning of every year, LinkedIn publish a content calendar in Slideshare. The idea is that publishers (such as me and you) will produce an article on LinkedIn (publish a post), which will include the topic and hashtag. These articles will have priority (but you need to make sure that the hashtag is listed at the bottom of the article).
We have now changed our blogging strategy at GUHQ, along with the clients that we blog for, to include an article on the chosen topic once a month.
