Cost Per Click (CPC): Learn What Cost Per Click Means for PPC

Cost Per Click (CPC) refers to the actual price you pay for each click in your pay-per-click (PPC) marketing campaigns. In this lesson you'll learn:

  • A more thorough definition of cost per click.
  • Why CPC is important to you and your PPC campaigns.
  • How to lower your cost per click while maintaining (or even improving) traffic and conversion levels.

A "click" on one of your PPC text ads represents a visit, or an interaction with your company's product or service offering. Every click in a PPC campaign represents attention from a person who is searching for something that you offer. This attention is what you're buying, as an advertiser, so it's important to note two factors:

  • What type of attention you’re going after, and
  • How much you’re paying for it.

How Is Cost Per Click Calculated?

The actual formula for cost per click in AdWords is:

 

Cost per Click Formula

 

As an advertiser, your cost per click will always be less than or equal to your maximum bid, as it is an average of bids against a series of competitors over a period of time. Because of how Google's Adwords Auction works, your actual cost per click is heavily influenced by both you and your closest competitor's ad rank, maximum bid, and Quality Score.

The Importance of Cost Per Click in Search Advertising

Cost-per click is important because it is the number that is going to determine the financial success of your paid search campaigns.

Your return on investment, whether you're over- or underpaying for each action, will be determined by how much you are paying for clicks, and by what kind of quality you are getting for that investment.

Since the overall ROI of your campaigns is determined by how much you’re paying for clicks and the quality of traffic they’re bringing in, it is important to think about cost per click in terms of both cost and value. You want to identify and target clicks that are both inexpensive and valuable. 

Lowering CPC While Maintaining Value

So how do you go about lowering the price you're paying for each click, while sustaining (or even improving upon) the value of your visits? Two key paths of action come into play here:

Raise Your Quality Score – Google has created an automated system that offers pricing discounts to well-managed PPC campaigns with high Quality Scores. Currently, accounts with quality scores of 6 or higher (the average score today is 5) are granted a 16-50% decrease in CPC, whereas accounts with a 4 or lower Quality Score see a 25-400% increase in CPC! 

Google AdWords Cost Per Click

Boost your chances of a drastically discounted cost per click by adhering to Quality Score best practices:

Expand Your Reach – By discovering new, relevant and valuable clicks, the distribution of your budget will be improved substantially. To do this, you’ll have to find new PPC keywords and search advertising opportunities. But you can’t just expand without also paring back – you need to simultaneously eliminate irrelevant or overpriced clicks from your campaigns.

Refine Your Reach – Continually designating negative keywords in your AdWords account helps to control your CPC by filtering out traffic from searchers that are highly unlikely to convert. So as you add new keywords to your AdWords account, be sure to eliminate the losers. When you target only keywords that perform well and are relevant to your business, it ensures that:

  • Your spend is protected – Lowering your cost per click isn't useful if you're paying low prices for irrelevant clicks. Negative keywords tell your PPC campaigns which terms not to target, therefore reserving your budget for relevant terms only.
  • Your Quality Score improves – If your keywords are clearly related to your ad text, landing pages, and offering, your click-through rate and other Quality Score factors will be positively affected. This gets you more cost-efficient clicks (remember, up to a 50% decrease in CPC!), and on search terms that are more likely to convert.

A low cost per click is key to PPC success because it ultimately translates into your cost per conversion. You’ll learn more about that in the next lesson.
