What does the "cost" metric in competitor analysis represent?

The "cost" metric in competitor analysis, particularly within tools like SEMrush, represents the estimated amount a competitor would have to pay if they were acquiring their organic search traffic through paid advertising (e.g., Google Ads). This metric is calculated by multiplying the estimated organic traffic volume for specific keywords by the average Cost Per Click (CPC) for those keywords. It provides a valuable benchmark for understanding the monetary value of a competitor's organic visibility. It is not the actual advertising budget, as competitors may or may not be running ads. It also doesn't reflect the cost to build a website or their spending on SEO tools, which are unrelated to the value of organic traffic.
