How to Use the Competitor Ad Spend Estimator
You can't know exactly what a competitor spends on ads, but combining total market impression volume, their estimated impression share, and average industry CPM gives you a reasonable ballpark figure. This calculator multiplies total monthly market impressions by the competitor's share to estimate how many impressions they're likely capturing, then applies the average CPM to calculate estimated monthly and annual spend.
You can estimate impression share using ad library tools, how often their ads appear in relevant search results, or share-of-voice (SOV) data from market research reports.
Actual bid prices can vary widely from the industry average depending on targeting precision and creative quality, so treat this output as a directional signal of competitive intensity rather than a precise budget figure; real campaign data should take priority for actual planning.

No, it's a rough estimate based on impression share and typical CPM rates. Actual spend varies with real bidding strategy and targeting, so treat this as a directional benchmark rather than an exact figure.
