I've hardly ever used paid advertising during my umpteen years of publishing on Amazon, and in fact I hardly need to for my long-running mystery series as the readers just seem to go on to the next one as it comes out (though only in the UK on Amazon and sometimes in Canada on Kobo). So I released the 18th in the mystery series towards the end of May and it has probably sold at least 1,000 or so copies without any advertising except a post on my Facebook page, not boosted or anything, which is fine.
For various reasons I had the second in a historical series ready a couple of weeks later, decided to do what I did with the first in that series this time last year, which was to put it in KU so that I could enter it for the Storyteller contest, and it sold about 5 copies and got a few hundred page reads. I realised it was quickly sinking without trace so I thought I had better do something to increase its visibility for the contest and in the hope of some reviews.
I rashly used my KU free days for both the books in the series all at once and did the following miniscule promotions:
Boosted Facebook post announcing the freebies, starting on the first free day, max cost GBP35.
Result so far (this is still going on) - noticeable immediate boost on Amazon Uk and quite a lot of engagement on FB.
Fussy Librarian ad on 2nd free day - cost USD35
And
Awesome Gang on same day for USD10
(I think I should probably have separated these out but never mind)
Thanks to Denise for her recent post mentioning Fussy Librarian as I wouldn't have thought of trying it. I was favourably impressed with some features of Awesome Gang , i.e. author interviews.
Result so far - noticeable boost in USA, about 1,000 downloads of the two books of which only the second was actually advertised.
Oddly enough both in the USA and UK the books have both risen from almost nowhere to the top 300 in the free store and to 4 or 5 in their 'historical Regency' sub-category, although the number of downloads isn't nearly as large in the UK.
I'm pleased with these results so far, not expecting much more for this free run but I will leave the FB boost going to try and get more UK readers.
I know this is very small compared with some of the promos other people have reported on but I thought it might encourage some others who don't really do marketing to give it a try.
