If advertisers want to place ads in search engines, they must be created in an advertising system such as Google or Microsoft Ads. The respective advertising system handles the distribution of the ads in the previously defined advertising network. Once a user clicks on an ad, the advertiser must pay a set amount, which was previously determined by the “cost-per-click” model. The exact click price is defined by several factors. The advertiser sets a maximum CPC bid for each keyword. The bid is offset against the quality factor , resulting in the ad rank.
In addition to CPC, other billing models such as “CPO – Cost per Order”, “CPM – Cost per Mille”, or “CPV – Cost per View” are also used in online marketing. If you want to know how to leverage CPC and search engine advertising for your business, contact us.
How are the costs for CPC determined?
Various factors play a role in determining the CPC. Since Google Ads is a type of auction house for advertisements, the highest bid significantly influences how high the costs ultimately are. However, the highest bidder does not always win the auction, and the highest bid does not always reflect the actual CPC that is to be paid at the end. The Quality Score is also a crucial factor. Google assigns this to advertisers, with user experience, quality, and relevance serving as evaluation criteria.
An example: Bidder A has a Quality Score of 5 and bids €3. Bidder B has a Quality Score of 6 but only bids €2.70. Although Bidder A has placed a higher bid, Bidder B wins the auction because: A: 5×3= 15; B: 6×2.70= 16.2.
Even if the highest bidder wins, it does not necessarily mean that the submitted highest bid corresponds to the actual CPC. This is actually based on the bid of the next highest bidder and can therefore be significantly lower than the maximum bid.
Advantages and Disadvantages of CPC
Cost per Click offers advertisers significant advantages. They only pay when a user has actually seen the ad and shown interest in it. This fundamentally distinguishes CPC from other payment methods in online marketing, such as CPM.
However, Cost per Click also brings disadvantages. For instance, fraud is very easy to commit, as clicks can be generated quite simply. Additionally, advertisers must pay for every click. So even if a single user clicks on the ad multiple times, the advertiser has to pay each time. This can quickly deplete the advertising budget. Also not to be overlooked are accidental clicks. Studies have shown that users, especially on the mobile version, tend to click accidentally and thus incur costs.
Alternatives to the CPC Method
In addition to Cost per Click, there are other payment methods for billing digital advertisements. Previously, CPM was mentioned. This abbreviation stands for Cost per Mille. Unlike CPC, CPM is based on impressions, meaning the ads displayed on a website. The advertiser pays a fixed amount for which Google has shown their ad a thousand times on various websites. It is completely irrelevant whether users have noticed the ad, let alone clicked on it.
The CPA model appears to be somewhat more sophisticated. In the so-called Cost per Acquisition, advertisers pay for each conversion. What exactly this means in a specific case can be determined by the advertiser themselves. This could be, for example, the completion of a purchase in an online shop, but also a download or signing up for a newsletter. CPA is indeed more expensive than CPC and CPM, but it is usually also significantly more effective. In connection with CPA, there is also often talk of CPO (Cost per Order) and CPL (Cost per Lead), where you pay for each generated contact address.
