CPC vs Buffered Earning vs Metered Earning

Khas buat kawan2 yg belum faham apa perbesaan spt di atas tu, ini aku copy dari nuffnang:

• There are 2 types of general paid ads from our advertisers, CPC (Cost Per Click) Campaigns and CPM (Cost Per Impression) Campaigns. The MCPM (Metered CPM) is a branch of CPM campaigns.
• CPC Campaigns
  Launched on advertisers' request. It will show on all blogs under Nuffnang network which have 'Show Global CPC Ads' selected under their Blog Preferences in Blog Manager. CPC Campaigns will only be shown on blogs which are not serving any CPM campaigns at the moment. Bloggers are payed based on the number of unique clicks by their blog's unique visitors. A CPC Campaign will ceased once it reaches its maximum clicks and commences update to all bloggers' account whose blogs generated genuine clicks during the campaign. If a blog has served the CPC Campaign ads but did not generate any clicks towards the campaign, no earnings will be updated to the blog owner's account.
• CPM Campaigns
  Our Advertisers will choose which blogs they want to advertise on as they pay much higher compared to CPC-type campaign. Their decisions may rely on several factors such as the demographics of your blog readers, the desirability of ad units, membership exclusivity and the availability of ad units. If you're chosen for one, you'll either receive an email notification regarding the campaign or find it in your "Buffered Earnings" section under the "Earnings" page.
  • As the Advertisers always have a target audience for their campaigns to address to, they will choose blogs with suitable blog readers as their target audience. Should your blog readers fall into that category, rest assure that you're very likely to be picked by them.
  • Desirability of ad placement is crucial in the advertising industry. Our Advertisers have spent 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. Just ensure that your ad units are at their intended place and this factor would be satisfied in the eyes of the advertisers. 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. Should your blog's ad units are not located at these placements, it would severely affect the Advertisers' decision to choose your blog and they might choose other blogs under our network instead with a more subtle ad placement.

How much do I earn?

For CPM campaigns

• What you earn depends on the number of Average Unique visitors you received in the week that the ad campaign is built.
• You will then be arranged into specific “Blogger bands” that directly correspond to your number of Average Unique visitors.
• For each campaign, you will be paid a fixed amount for every ad unit. The amount depends on what your Blogger band is. The higher your Blogger band (i.e. more unique visitors), the higher your earnings.
• All information on your blogger band and your earnings can be viewed within your CMS Earnings Page. All information will be updated within 3 working days after the ad campaign is completed.

For CPC campaigns

• You earn by the number of unique clicks generated by your unique visitors on the ad unit that is running the CPC campaign.
• Your earnings will be credited 3 days after the CPC campaign ends. A CPC campaign ends when it reaches its maximum number of clicks.
• Should your blog display a CPC ad but not generate any clicks on the ad unit, no earnings will be accumulated and updated.

For MCPM (Metered CPM) campaigns

• Advertisers buy a set of unique visitors from your blog that will be able to see their ads on your blog for a certain number of weeks.
• The earnings for your mCPM campaign will be held in Buffered Earnings while the campaign is running till your blog finish serving the number of uniques the advertisers bought from your blog. Once your blog finish serving the number of uniques, the earnings will be credited to your Current Earnings.
