giveaways are totally useless in term of marketing.
I got a dude saying he'd give me a positive review in exchange for the game and some keys and I couldn't help but feel a bit disgusted. Fortunately, I don't depend on my game to survive financially so I don't need to do shady
How Steam Keys Impact Review Score
Steam keys have always been free for developers to give out or sell through other online or retail stores. That isn't changing. However, it is too easy for these keys to end up being used in ways that artificially inflate review scores.
An analysis of games across Steam shows that at least 160 titles have a substantially greater percentage of positive reviews by users that activated the product with a cd key, compared to customers that purchased the game directly on Steam. There are, of course, legitimate reasons why this could be true for a game: Some games have strong audiences off Steam, and some games have passionate early adopters or Kickstarter backers that are much more invested in the game.
But in many cases, the abuse is clear and obvious, such as duplicated and/or generated reviews in large batches, or reviews from accounts linked to the developer. In those cases, we've now taken action by banning the false reviews and will be ending business relationships with developers that continue violating our rules.
While helpful users in the community have been valuable in reporting instances of abuse, it's becoming increasingly difficult to detect when this is happening, which reviews from Steam Keys are legitimate, and which are artificially influenced.
Changes To The Review Score
As a result of this, we are making some changes to how review scores are calculated. As of today, the recent and overall review scores we show at the top of a product page will no longer include reviews written by customers that activated the game through a Steam product key.
Customers that received the game from a source outside of Steam (e.g. via a giveaway site, purchased from another digital or retail store, or received for testing purposes from the developer) will still be able to write a review of the game on Steam to share their experience. These reviews will still be visible on the store page, but they will no longer contribute to the score.
