Although cost-per-click, or CPC, advertising is enjoying great popularity, CPM (cost per thousand impressions) advertising is still an effective way of reaching potential customers on the Web. Instead
CPM-based advertising can be a cost-effective alternative to CPC deals. To illustrate this point, let's compare the overall expense of two similar campaigns.
In CPC-based advertising, you pay for each click your ad receives. Let us say that you are spending $1 for each click; 10 clicks costs you $10.
In a CPM-based campaign, you may pay $3 for 1,000 impressions. If your ad receives a click-through ratio of just 1 percent, you're paying $3 for the same 10 clicks.
Current results have shown that text-based CPM ads often receive more attention that traditional banner ads. In fact, the average view time for a text based ad averaged 7 seconds, while a graphical ad only averaged 1.6 seconds. Text CPM ads are starting to become more popular and may be a viable alternative to CPC-based advertising.
