when it will be sufficient

when it will be sufficient to join my blog with google adsense.i would like to tell you that at that time my site is no longer days to go and i have no more visitors.so please help me learn more

Good question,

If I understand you correctly, you want to know when you should apply AdSense ads to your blog? Theoretically you could apply AdSense ads any time you want however you will not start seeing revenue until you have a moderate amount of traffic every month. The amount of traffic that you need to generate in order to have visitors clicking on ads will vary based on your site's content and the types of ads being shown.

There are a variety of ways that you can drive traffic to your blog but your number one way will be to generate interesting content that people want. Whether it's purely writing, video, images or some combination, you need to find a way to get people interested in the blog and then they will visit on a regular basis and some may click ads that you have running.

Here are links to information on driving more traffic to your blog,
