WHY PPC IS CONCAVE TO THE ORIGIN
What is PPC?
PPC, or pay-per-click, is an online advertising model in which advertisers pay a publisher (typically a website, app, or search engine) each time a user clicks on one of their ads. This model is commonly used in search engine advertising (SEA), display advertising, and social media advertising.
How Does PPC Work?
PPC advertising works on an auction system. Advertisers compete against each other to have their ads displayed in the most prominent positions on a publisher's website or app. The highest bidder typically wins the auction and pays a cost-per-click (CPC) to the publisher. The CPC is the amount that the advertiser is willing to pay each time a user clicks on their ad.
Why is PPC Concave to the Origin?
The PPC curve is concave to the origin because the marginal cost of clicks (MC) increases as the number of clicks (Q) increases. This means that the more clicks an advertiser gets, the more they have to pay for each click.
There are a few reasons why the MC of clicks increases as Q increases:
- Competition: As more advertisers compete for the same keywords, the price of those keywords increases. This is because advertisers are willing to pay more to get their ads displayed in the most prominent positions.
- Quality Score: Search engines like Google use a quality score to determine the relevance and quality of ads. Ads with a higher quality score are more likely to be displayed in the most prominent positions and are charged a lower CPC. This means that advertisers need to improve the quality of their ads to get a lower CPC.
- Ad Fatigue: As users see the same ads repeatedly, they become less likely to click on them. This means that advertisers need to rotate their ads regularly to keep them fresh and engaging.
Implications of the Concavity of the PPC Curve
The concavity of the PPC curve has a number of implications for advertisers:
- Diminishing Returns: The law of diminishing returns states that as more of a resource is used, the additional benefit from each additional unit of the resource decreases. This means that the more clicks an advertiser gets, the less valuable each additional click is.
- Optimal Advertising Budget: The optimal advertising budget is the point at which the marginal cost of clicks equals the marginal revenue from clicks. At this point, the advertiser is getting the most value for their advertising spend.
- Importance of Targeting: Targeting is the process of selecting the right audience for your ads. By targeting your ads to users who are most likely to be interested in your products or services, you can increase the effectiveness of your advertising and get more clicks for your money.
The concavity of the PPC curve is an important concept for advertisers to understand. By understanding this concept, advertisers can make more informed decisions about their advertising budgets and strategies.
