Sorry, I misinterpreted the comments on your item. It seems you were missing login info for your demo, rather than the demo itself being down.
But the basic idea is unchanged – how do you know that the missing login info didn’t cost you five potential sales? Sure, it may sound ridiculous, but you cannot say with certainty that it’s false. The point is, nobody knows why sales are down for a particular item or author. It’s too complex of a question, and too impossible to answer.
Anyway, the laws of supply and demand dictate that in a large market, there must be products that get little or no sales. I don’t have time to look much into your particular item or scenario, but one of three things is happening here:
- Your item is less attractive than another competing item, or;
- Your item is in a category with low demand and high supply (i.e. there’s not enough people to buy all the items that are available), or;
- Your item has poor exposure (what are your analytics like compared to your other items?)
CodeCanyon provides free exposure through on-site search, follow feeds, recommendations, and SEO. This is generally more of a slow exposure over time, though. If this is why your item is failing, you can expect sales over time.
Ultimately the one piece of advice that is most repeated on these forums is applicable here: Keep creating. If you consistently put out new items, you will gather more attention - not only to those new items, but your existing items as well. And who knows? Maybe one of your future items will hit a jackpot and shoot you straight up to Level 12.
