I have to say that being prepared early is definitely a great idea, last year was my best Christmas sales ever. I started my first Christmas lens at the end of Jun/beginning of July and the niche I developed started selling in September and continued into February. My lenses had had enough time to be seen as established and they were also interlinked well so that they feed each other. I was extremely happy.
Now that’s not to say last minute lenses can’t do well. During September one of my popular lenses started to get a lot of hits for people looking for Halloween lenses in this niche. I set up a lens in response thinking that I’d left it a little late……every day except one (and I think there may have been problems with reporting on that day) I made a sale throughout October and that lens continues to have made me the most money out of any of my other lenses.
I guess what this means is that there’s no clear ‘best time’ to write any lens. Personally the last few weeks I’ve been (in what time I’ve managed to find) alternating between Halloween, Christmas and evergreen lenses. What that means is that I’ve been juggling so many ideas I was shocked to discover it was April!!
Good luck with whatever kind of lenses you’re working on at the moment and remember if you have a lens that offers help with Squidoo or lens promotion then drop me a line and I may just feature you here.
