Don't worry about the amount of visitors, make sure that you have enough good quality content on your site...that is what will matter.
yes , just add article more about technology like mobile, laptop etc. that will get more easily ad-sense approval.
I started at 1 visitor a day(me). A month later and I'm at 500 visitors/day and growing, adsense still isn't making much just yet though. Not until I hit ~10k/day.
Nothing to worry about the visitors. Emphasize more on creating quality, interesting and unique content. Visitors will increase day by day. Try to optimize your site to the major search engines or try to apply some strong ways to increase traffic. There are lots of ways that are really helpful. I can prefer to read out this site - http://www.wikihow.com/Increase-Website-Traffic
I like the suggestions of increasing traffic, just make sure you increase the traffic naturally, and optimize you page so that it is adsense compliant, yet encourages an acceptable click through rate. I think 100 a day is acceptable on face value, I would like to know where the 100 are coming from as I believe that is very relevant.
It depends if it's worth it to you. You need to think of the trade off between displaying advertisements to all your visitors versus how much you will make with adsense. With 100 visitors per day it may be worth it.
Its not about the amount its about the quality of the visitors. The amount doesn't matter anyway, you can always apply for adsense and its up to them if you get approved or not.
You need to think about the balance between the ads that will appear on the amount you will receive when you have 100 visitors per day.
the amount of visitors no less important than the content ! but with good quality content and 100 visitors, you doing well
The key to google adsense success is really quality content, something most people ignore or don't put quality time on. Don't expect to make much from adsense if you are not willing to put the work into it.
Depending on how well you are creating content in line with your site concept will determine the appropriateness of the ads.... By all means go ahead and start placing them on your pages if you have some traffic.
i am getting 40 visitors per day and i have just registered for google adsense. I believe you should have started much earlier. better late than never .
