Twitter Daily #Hashtags for Writers
One way to have personal tweets stand out is by using hashtags. Anyone who uses Twitter for a day knows that hashtags are a way to target a tweet to particular interests, i.e #mystery or #romance.
You can go beyond category hashtags, however, with a whole week of hashtags designed to introduce your content to engaged readers, you could continue to use hashtags only to boost your current Twitter book marketing.
Using the chart below, tweet what is relevant to that hashtag on the specific day:
#MondayBlogs: Tweet a link to a blog post from your blog or another author’s. Ideally the blog is published on that Monday.
#TeaserTues: Tweet a link to an excerpt, with a brief but tantalizing quote from it.
#WW or #WriterWednesday: Give a shoutout to fellow authors, with a short reason for following them. You can list more than one author in a tweet. It’s a nice thing to do, plus a great way to build a following.
#IndieThursday: Tweet a shout or a link for a fellow indie author, or just a link to your own indie-pubbed book.
#FridayReads: Tweet suggested weekend reading. Yours of course, but also books you recommend.
#SampleSaturday: Share a one sentence writing sample, put it in quotes, and add the link to the book.
#Sample Sunday: the same as Saturday but possibly a bit more well known to readers surfing for their next read.
Click on some of these and see what you get. Savvy Tweeters will notice some of these links are accounts (@) and some are Hashtags (#) Often the Account sponsors the Hashtag, and retweets you when you use it.
