What is CPC?

Cost per click (CPC) is a key metric in digital marketing. Advertisers pay publishers under this pricing model every time a user clicks on their ad. Since it sets the price an advertiser has to pay to send traffic to their website, cost per click (CPC) is a vital part of the digital advertising industry. The industry, the target market and the level of competition are some of the factors that affect the cost per click. Digital marketers who want to maximize their ad spend and optimize their campaigns must understand cost-per-click (CPC).

Factors affecting CPC

Many elements shape your CPC in digital ad campaigns. Marketers aiming to boost ROI must grasp these drivers. From fierce keyword competition in India’s ₹59,200 crore ad market to crafting compelling ad copy, each factor counts. This section explores what influences CPC in 2025, like AI-driven targeting or vernacular ads, and shares practical tips to lower costs.

Ad relevance

One of the biggest factor that can affect your CPC is how relevant your ad is to the target audience. A more relevant ad to the user increases the chances of them to interact with it resulting to a higher click-through rate (CTR) and lower cost per click. Make sure your ad copy and targeting is relevant to those who are interested in fitness for instance if you are running an ad for a fitness product.

Competition

Your industry’s level of competition can also affect your CPC. If multiple advertisers are bidding for the same keywords, the cost per click is expected to increase. This is especially true in highly competitive industries like insurance or banking. Targeting long-tail keywords that are less competitive but still relevant to your audience is crucial in these cases.

Ad placement

Your CPC can also be affected by where your ad appears on the search engine results page (SERP). Ads above the fold tend to have higher CPC than those below. This is because ads above the fold are more likely to be clicked and are more visible. Remember though that there are times when there’s no direct link between ad position and CPC and finding the best ad placement requires some trial and error.

Quality score

Another big factor that can impact your CPC is your ad’s quality score. A metric called quality score measures the quality and relevance of your landing page, keywords and ad. Ads with higher quality score are thought to be more relevant and helpful to the user so they have lower cost per click. Focus on writing relevant ad copy, choosing the right keywords and improving your landing page to increase your quality score.

How to Calculate CPC (Cost Per Click)

In the world of digital marketing, CPC or Cost Per Click is a metric you can’t afford to ignore. It tells you exactly how much you’re paying every time someone clicks on your ad. Knowing your CPC helps you measure how efficiently your ad budget is being used and whether it is bringing you real value.

Calculating CPC is straightforward. It measures ad spend efficiency.

• Formula: CPC = Total Campaign Cost ÷ Total Clicks.

• Step 1: Sum campaign costs (ads, creative fees). Example: ₹15,000.

• Step 2: Check clicks on Google Ads dashboard. Example: 600 clicks.

• Step 3: Divide cost by clicks. ₹15,000 ÷ 600 = ₹25 CPC.

• Analysis: Compare CPC to industry benchmarks. ₹25 is low for Google.

• Tools: Use Google Analytics or Meta Business Suite for data.

How to Optimize CPC

Maximise your ad spend by optimising your cost-per-click (CPC). The cost per click (CPC) you pay when someone clicks on one of your ads. Make sure you’re getting the most clicks for your money by optimising your CPC. Your CPC is affected by many factors such as your bid, ad relevance and user experience on the landing page.

Here are the ways to optimise CPC:
