At first, thanks to Nuffnang Team for this sharing. So, I'm gonna share this with all of you. May it's worth for everyone.
Thanks for the details! One way is to increase your blog traffic :)
To increase your traffic, consistent updates on your blog is crucial. Also, write about topics and issues that you are interested in, that way you can attract more readers of the same interest hence strengthening your blog demographics. Make sure that your content is interesting to attract readers back to your blog. :)
With this, allow me to explain about CPC and CPUV ads. Hope this is not too long of an explanation.
Bloggers earn when they serve paid ads from our advertisers and not just by having empty ad units in their blogs.
There are 2 types of general paid ads from our advertisers, CPC (Cost Per Click) Campaigns and CPUV (Cost Per Unique View) Campaigns.
CPC (Cost Per Click) campaigns are launched on advertisers' request. It will show on all blogs under Nuffnang's network, which have 'Show Global CPC Ads' selected under their Blog Preferences in Blog Manager that are not serving any CPUV (Cost Per Unique View) campaigns during its launching period.
Bloggers will be paid based on the number of unique clicks by their blog's unique visitors. It will cease once it reaches its maximum clicks. If a blog showed CPC ads but did not generate any clicks towards the campaign, no earnings will be updated.
For CPUV (Cost Per Unique View) campaigns, advertisers choose which blogs they want to advertise based on several factors such as the demographics of your blog readers and the desirability of ad units. These ads pay according to the unique impressions the advertiser purchase from your blog, which are the readers that will be able to see the ad. It doesn't require any of your users to click on it in order for you to get paid.
As advertisers always have a target audience for their campaigns, they will choose blogs with suitable blog readers as their target audience. Should your blog readers fall into that category, rest assured that you're very likely to be picked by them. Many bloggers who do not fill in their blog surveys may find themselves not receiving ad campaigns from advertisers frequently.
This is because the survey actually helps advertisers know the bloggers' blogs better. Blogs registered without completed surveys are often ignored by advertisers as they do not know if your blog's reach is suitable for their campaign. As such, we'll highly recommend for you to ensure that all your blogs' surveys are filled and updated from time to time.
Desirability of ad placement is crucial in the advertising industry. Advertisers spend a lot of money to design an ad and buy ad space. They want to get their message across to their target audience as effectively as they could. This being said, they will always buy ad spaces which are optimized and desirably placed. A Skyscraper ad unit is supposed to be the first element of the sidebar and not anywhere else.
The same goes for Leaderboard as the first visible element upon visitor's entry to the site and Large Rectangle right after your first blog post. When your blog's ad units are not located at these placements, it would severely affect the advertisers' decision to advertise on your blog as there are plenty of other blogs under our network with perfect placement of the ad units.
In addition, availability of ad units plays an important role for bloggers to be chosen for campaigns as well. All our advertisers split their budget evenly across all our 3 ad units, Leaderboard, Skyscraper and Large Rectangle whenever they advertise with us. That being said, the budget would be limited and might not be able to cover that many blogs for a particular ad unit. If your blog have all 3 ad units in it, your chances of being selected for campaigns would be fully maximized.
We'll do our best to sell the ad units of our bloggers as long as they're optimized and within our protocols. If the ad units are not optimized or they're not in the best interest for the advertisers, we cannot defile the practice of our company's policies and have our advertisers advertise on blogs which do not yield the best results for their campaigns. I hope that you will understand that it is important for advertisers to achieve satisfactory results for their campaigns in order for them to advertise more on blogs.
Trust in our system that if your blog has earned from campaigns, they will be credited to your earnings in due time.
Thank you and have a nice day!
