Mastering SEO involves understanding a wide range of concepts like keyword analysis, page optimization, and user engagement strategies. If you’re just starting or want to refine your expertise, our series of SEO glossaries will be a beneficial tool for grasping the essential terminology and principles that influence effective SEO. Among these concepts, high CPC keywords are particularly noteworthy – what makes them critical? How do they function, and how can you identify and leverage them?
What are high CPC keywords
First, let’s start with definitions of CPC. Simply speaking, CPC – Cost Per Click – represents one of the most common programmatic media buying pricing models; it tells the average cost an advertiser pays when a user clicks an ad. However, publishers should also be aware of the risk of users’ misclicks. If they happen too often, and due to, for instance, implementing practices prohibited by Google, the company might decide to inflict Confirmed Click, a feature asking users who clicked an ad if they really want to be redirected to the advertiser’s site.
Now that you know what CPC is, it’s time to define high CPC keywords. They are search terms that allow to earn higher than usual sums of money. Their high value may be caused by several factors:
- High industry demand refers to the popularity and importance of specific industries where many companies want to advertise their products or services. Because so many businesses compete to reach the same audience, they are willing to pay more to show their ads for specific search terms (keywords);
- Another type of keywords that usually have high CPC is keywords connected to fields in which people are quickly ready to buy or commit to a service. An example of such a service would be legal advice, as legal issues typically cause stress, and individuals are eager to resolve their problems as fast as possible;
- In a niche market, if the audience is highly valuable, it usually doesn’t matter if keywords don’t have very large search volumes, the publisher can still be handsomely paid if the users click an ad. An example of such a niche would be some specific tech solutions.
The role of negative keywords
Another term publishers should understand in the context of high CPC keywords is negative keywords. These are keywords that advertisers use to filter out irrelevant traffic from their Google Ads campaign. For example, an advertiser selling luxury handbags might set terms like “Birkin bag alternative” or “cheap handbags” as negative keywords to avoid clicks from users unlikely to make a purchase. Ok, but what can a publisher do with such a piece of knowledge? You can try to put yourself in advertisers’ “shoes” and avoid putting certain phrases in your content in order not to attract irrelevant, low-value traffic. An example of applying such a strategy would be avoiding phrases like “cheap watches” when you wish to maintain a premium audience for your website about luxury accessories.
Why should publishers care about CPC keywords
In the digital marketing world, understanding and utilizing high CPC keywords is essential not just for SEO strategies but also for website monetization efforts:
- When it comes to the SEO context of high CPC keywords, by optimizing for such high-intent keywords, websites can attract qualified traffic. What’s more, crafting content that answers user queries around these terms can position a site as a trusted resource, driving more organic traffic over time. Importantly, not all such keywords have a very high search volume, as there are some specialized industries or niches that might have strong competition but have a relatively small number of queries;
- As for the monetization context of high CPC keywords, websites that include such keywords can attract more valuable ads and, thus, generate higher ad revenue, as each click should offer a competitive rate. What’s more, advertisers are usually ready to spend more for clicks on ads tied to those phrases.
So, in summary, while you perform keyword research, it’s recommended to find precious high CPC keywords, as these words can benefit both worlds – SEO and monetization!

Where to look for high CPC keywords
If you are planning to do your own keyword research, it’s best to choose the tool that will help you the most. One of the most popular and helpful solutions for finding the most expensive Google keywords is Google’s Keyword Planner, but also Ahrefs, SEMrush, and Ubersuggest. The advantage of a Keyword Planner is that it’s free, all you need is a Google Ads account. In the case of Ahrefs, the company shares a free keyword generator, but all the most useful options are only available to premium users. Both SEMrush and Ubersuggest are paid solutions, but they offer free trials.
How does Google Ads determine keyword costs
The final keyword cost is calculated by Google based on various factors. The two most relevant ones are:
- Quality Score – Google Ads evaluates the ad relevance, chances of people clicking an ad, and UX of the advertiser’s landing page;
- Ad Rank is the formula for determining whether the ads are appropriate for a display and, if so, how high or low they are placed on the page compared to competing ads.
What is the most expensive keyword category
As with everything else, there are some categories of keywords that are more valuable than others. If you are wondering what the most expensive keyword categories are, below you’ll find four of those:
Loan keywords
Loan keywords position themselves as one of the most expensive keyword categories. One of the reasons for that is for sure their high value but also fierce competition among advertisers. Here are a few examples of such keywords: “the best student loan companies”, “apply for business term loan”, or “low rate small business loans”.
Legal keywords
Some of the most expensive keywords are those from the legal industry. Undoubtedly, this field has a lot of money in it, and usually, people are quick to pay for the service. An example of high CPC keywords from the law industry might be “accident lawyer woodland hills”, “motorcycle crash attorney atlanta” or “pedestrian accident attorney”.
Insurance keywords
Insurance keywords are so expensive, mainly due to high demand, the fact that these keywords are premium, and such services can create significant revenue over time. High CPC keywords examples are, for instance, “century insurance claims”, “what to do if i lost my insurance card” or “allstate insurance apple valley”.
Education keywords
Education is yet another field where high CPC keywords can be found. Many people are searching for degree programs that might help them on their professional journey. “online schools for education majors”, “online colleges for masters in social work” and “online schools early childhood education” are a few examples of high CPC keywords.
