Andy Brice of the Successful Software blog has written a list of 100 ways to increase software sales in 2009. They come in 5 categories: website traffic, trial conversion rate, sales conversion rate, value per sale, and alternative sales channels. Not everyone idea is a priceless gem, but a surprising number of them are. Some of which might be just right for your product and others may lead you to think of similar ideas that would work well.

Things I plan to try from the list are TrialPay and promoting software on one day sale sites, such as BitsDuJour or GiveAwayOfTheDay.

Some of the 100 ideas are specific to downloadable software, and some of them are specific to micro-ISVs. Even if 99 of these 100 ideas are not right for your product, that means one of them is and you have an immediate action you can take to boost sales in 2009. Go check out the list.
