This can negatively affect the click-through rate and conversion rate of the advertisements, leading to a decrease in the overall performance of the campaign.2. Increase in CostKeyword Cannibalization can intensify competition by bidding on the same keyword, potentially leading to an increase in the cost per click. As a result, advertisers may end up paying more to acquire the same traffic.3. Decrease in ROIThe decrease in effectiveness and increase in cost can potentially lead to a decrease in Return on Investment (ROI). Due to Keyword Cannibalization, the advertising budget may not be used efficiently, potentially leading to a decrease in profitability.4. Difficulty in Data AnalysisWhen multiple advertisements compete for the same keyword, it becomes difficult to determine which advertisement is the most effective.
