Try typing ‘How to tweet’ into Google. Finished? Now try to plod through the 153m results… if all of these meet the ideal seven-minute read rule, you would need more than 1bn minutes to read the lot – that’s approximately 1,901 years, or roughly 21 times the life span of Thora Hird, who died a few weeks before her 92nd birthday.

Luckily, a free ebook can shorten that 1bn minutes to the mere time it takes to ascend 270m on a Stannah Chairlift (i.e. 30 minutes).

The title isn’t catchy, but then ’23 Quick & Easy Ways to Get More Twitter Retweets’ does what it says on the tin. Written by Boom! Social CEO Kim Garst (@kimgarst), the book provides much of the material you need to know – in fact, merely glancing at the book’s 27 chapter titles yields some useful lessons.

Here is a selection of the best:

1. Use mentions
2. Use hashtags
3. Reach other time zones
4. Tweet great content
5. Include a number
6. Use caps
7. Say thanks
