Generally it depends on the topic of my video each week. Some weeks I can get around 100 - 150 views before I upload the following weeks video and some weeks only 40 - 60 views. It simply just depends on the popularity of the topic you're discussing and also how well you promote your video throughout the week. Sometimes I will publish my video on other social media such as twitter, tumblr and instagram around 3 times that week sometimes only once. The impact of cross promoting on other social media platforms is amazing. If I didn't post my videos on these sites then my view counts would be considerably lower. It's also a good idea to consider following a number of twitter accounts which are dedicated to helping you promote your channel and it's videos for free. Every time you upload a new video and tweet about it, if you mention them in the tweet, they will most likely re-tweet it on their page which will be seen by a number of fellow new youtubers who also follow these accounts. It's also a great way to discover new youtubers and interact with them.
