大学生经常去哪些网站或论坛？
1.QQ我想每个上网的都差不多有吧！QQ空间和游戏里大学生应该不少。2大学生上网常做的事，上QQ,听音乐，看电影，玩游戏，看电子书，也有爱聊天的，要么查资料，所以有这些东西的网站特别是知名的以及搜索引擎排名靠前的网站是首选。3网吧，这个地方是大部分大学生上网的主要据点，可以考虑在网吧以搞活动的方式宣传，比如利用流行的电子竞技搞比赛等。至此，仅供参考
如何拓展校园市场
想要拓展校园市场，宣传是必不可少的。一个好的产品经营，必然是需要人才能够完善市场，也只有这样才能够真正获得更多的进步，也才能够打入校园市场内部，了解更多商机。好的产品必然是需要市场打磨，市场的拓展必然还是需要人才的带领，因此，必须要找到窍门才能够做好更多的成绩。
在校园内做市场，必然团队之间的协作也是非常重要， 定期地做一些促销和活动，必然是需要大家一起合作，这样才能够真正出成绩。
学生兼职，对于校园的市场也是有一定的帮助，可以从一定程度上帮助自己更好地掌握校园市场和用户者心理，这样也有利于市场的稳定。而对于很多人来说，如果能够在校园里拥有一个商品店，必然也是有很多生意可做，如果能够定期做些促销活动，是不错的办法。
虽然我们都是学生，但是说到生意上的市场必然还是需要进行一番调研的，只有这样才知道走什么样的产品合适，才能把市场拓展开，这一点是非常重要的。
