Game sites – Reviews and articles
Simply put, you want to attract gamers to your game and/or deliver your game to gamers. A great way to do both is to have exposure on game sites, either for an article or a review. They can reach large audiences. Even better, it will catch the eyes of gamers that are specifically interested in the genre of your game. So part of your marketing process must include reaching out to games sites and journalists. But where can you find them? Compiling a list of contacts is tedious work when you start from scratch, but it is important and will help you organize your PR efforts.
Here are some of the best mobile game review sites compilations that I have found to start building your PR mailing list. You can go through these spreadsheets, find the sites that are best suited for your game genre and platform. Check the lists one by one to filter out the broken links and repeats.
