¿Verdadero o falso? Es posible que tengas que ofertar más a medida que las palabras clave se hagan más restrictivas y competitivas para ver los resultados.

This statement is true. As keywords become more restrictive (e.g., long-tail keywords with more specific intent) and competitive (more advertisers bidding on them), the cost-per-click (CPC) generally increases. To ensure your ads appear prominently and achieve desired visibility and results, you often need to increase your bid. This is because a higher bid signals to the ad auction system that you are willing to pay more for that specific click, making your ad more likely to win the auction against competitors. Conversely, if you don't increase your bid, your ads may not show as frequently or at all, leading to a lack of results.
