Same thing happened to me, Aman. I've been rocking along consistently since Dec/Jan and about a week or week-and-a-half ago, it tanked. I'm still selling something everyday, but it is at a snail's pace now.
WAIT A MINUTE!! My best sales months were June, July, and August last year. They were huge. April just kicked March's backside and should pass Feb. by tonight. I've had my first month with a thousand sales in the UK. Germany has also had the second best month so far. My borrows are the second best since the program started. Six more before the nights over and it will be the best.
All I'm trying to say is that it won't be as bad as you think. people will be out of school and have time to read on vacation. Just hang in there. Publish a new book to boost your others. I really believe it won't be so bad.
I suspect this may be due in part to Google's latest search algorithm update. They implemented an update a few weeks back to weed out sites that they deemed to be ranked due to link spam, and it tanked a lot of small mom and pop businesses.
If your book sales have been driven by blog traffic or rankings in Google search results, check your rankings to see if your blog or Amazon sales pages have dropped.
In the past, these updates have tended to work themselves out over time. Google usually tweaks their search algorithm updates and things go back to the way they were, in most cases.
I'm being a smug bitch, my new book is doing rather well. Only the second day but I'll take whatever I get I spent in excess of £200 on the cover image and I've made that back already, so now it's all going towards my hourly rate lol. I've decided I'm making my own luck during the slow months - next release planned for August!!
Maybe not in the Winterless North (North Island of New Zealand), but heading south, it gets progressively colder through the central North Island ski fields to the South Island ski fields (probably as cold as the UK - or near as dammit!). We're sort of like a one stop weather shop!
I'm wondering if my winter is not already here! I have around 30 titles on my bookshelf. I sell between 15 and 20 of those in any one month, with a total of around 100+ sales per month (i.e. 3+ per day). Yet I have not had a single sale since 28 April - this is now day 4 of my winter. My walls are resolutely beige.
Should I be panicking? Heading for warmer climes? Or is there some other explanation for my sales just stopping stone winter-cold dead?
