I have books on SFbooks.com so I know what you mean and I appreciate the difficulty. I only hope your readers and future readers appreciate this as well.
Not sure having my books on this site created much of a sales spike so I would recommend that you must really push it on Twitter and other sources whilst it is hot news. I may not have done that. Perhaps ask other authors how best to promote a "special" review. Keep me notified as I need to learn from this. Once again though, well done. Put a link on your web but also put a recognisable picture from their web with it (like the Twitter bird symbol if you know what I mean). Best wishes
It's all a slow burn, I think - but I do tweet and facebook and am trying out some of the promo sites for my next 99p week in a couple of weeks (will be the last for a while, so want to hit it well if I can.) Have a look at some of @FibonacciEddie
's threads - he has some great tips for what works and what doesn't.
I didn't get a spike in sales from this review, but I think the culmative effect of the reviews is having an impact. (I'm on 5* over 9 reviews on Amazon UK and I'm hoping it keeps going to 10 so I can do a bit of singing and dancing with it) as there was a good spike this week. But it's about getting word of mouth out there and, also, building a name - I'm in this for another few books at least with 2 hitting next year and a couple more churning around agents and publishers and what not.
And Allen Stroud, the reviewer, also promoted the review, which was good.
Good luck with your own books.
