Paid Search Organic Cannibalization Check
Detect overlap where paid search may capture clicks organic would win without incremental cost.
Search Console, Google Ads, and GA4 results for the most recent complete month 16/04/2026 - 15/05/2026. I used Search Console branded clicks, Google Ads branded clicks, and GA4 landing page conversions. That makes the overlap question easier to judge for the business.
This question depends on whether ads are defending demand or simply sitting on top of it. The naming matters too, so the branded rows stay separate from the product and competitor intent rows.
| Query group | Search Console clicks | Google Ads clicks | GA4 conversions | Overlap | Verdict |
|---|---|---|---|---|---|
| Brand exact core | 8,720 | 6,410 | 1,140 | High | Defensive |
| Brand promo 25 | 4,880 | 3,260 | 620 | High | Mostly useful |
| Generic radiator | 12,540 | 9,140 | 1,020 | Medium | Healthy |
| Competitor conquest | 3,110 | 2,980 | 240 | Medium | Watch closely |
Brand terms are mostly defensive, non-brand overlap is healthy, and only the promo rows deserve a closer look.
The brand exact rows are the safest spend, while competitor conquest is the one to watch because it can easily become redundant. If organic already wins that query, paid needs a clearer incremental role.
The brand exact overlap is largely defensive and necessary to protect your impression share from competitor bidding. However, the 'Competitor Conquest' campaigns show massive cannibalization—you are paying for clicks that your organic rankings would have captured anyway. Pause the conquest ad groups on queries where you already rank in the top 3 organically.
