Absolutely nothing - lol!
I am still clueless about relevancy, and what keywords work, and what I should concentrate on. Most of my keywords only get 1 or two hits, in a month...so it's hard a decision to decide which ones to dump, since they all seem to be on par with one another!
Influx of sales in a week - Yep I have no clue why some weeks I will get more sales, and the following week it's dead as a doornail. Yes I could look at Google Analytic, but I can't decipher that program either.
Renewing- Who know's of that helps at all? Well I know it helps with one keyword, but it's not like when I renew something that I get an influx of sales. But who knows someone could see my item recently renewed and keep it in the back of their mind for a later date???
Working hard - It's seems the harder I try the less effective it is. Although I admit, doing new pieces of artwork quite regularly seems to build momentum. I know customers check back to see if I have done new 'works' recently.
Blog advertising - I have no real clue if that helps either, although I did see a good increase in facebook likes, and so may get potential customers later down the track.
Giveaways - Well that's one thing that I do see benefit to, whenever I do giveaways (on large blogs) I do get extra sales. Find a blog with lots of followers on facebook, twitter etc in your target market,
So yeah...there you have it I am clueless and not that business savy.
But one thing I have learnt, if I hadn't as a joke' put these illustrations up a year and half ago online, I would of never realised my passion, and what I am good at! So there is a lesson, 'try everything and anything, take risks, don't be afraid to fail and make mistakes, refine and master your skill'.
