Positive keywords tell Google which searches to show your ads for. Negative keywords tell Google which searches to actively exclude. Without them, your ads will appear for searches that are technically related to your keywords — but completely irrelevant to your business.
Example: You sell premium CRM software. You bid on "CRM software." Without negatives, your ad appears for "free CRM software," "CRM software tutorial," "open source CRM software GitHub," and "CRM software jobs." Every click from those irrelevant queries costs money and provides zero purchase intent.
For most accounts running broad match or phrase match, 15–30% of total spend goes to irrelevant queries during the first 30 days. Aggressive negative keyword management in the first month typically reduces wasted spend to under 5% — a significant efficiency gain on the same budget.
Phrase negatives provide the right balance of coverage and precision for most situations. Use broad negatives for single words that are universally irrelevant (like "jobs" or "free"). Use exact negatives when you need to block a specific query without blocking related variations.
| Level | Where Added | Scope | Best For |
|---|---|---|---|
| Campaign Level | Campaign Settings → Negative Keywords | Blocks across all ad groups in that campaign | Universal exclusions — "free," "jobs," "tutorial" |
| Ad Group Level | Ad Group → Negative Keywords | Only blocks within that specific ad group | Preventing cross-group traffic stealing (funneling) |
| Shared List | Tools → Negative Keyword Lists | Apply one list to multiple campaigns at once | Universal master list applied across all campaigns |
Most advertisers add negatives campaign by campaign. Shared negative keyword lists let you maintain one master exclusion list and apply it to every campaign with a single click. When you discover a new irrelevant term, add it to the shared list and it's immediately blocked everywhere.
These negatives are irrelevant for virtually all commercial Google Ads accounts. Add them before your first campaign goes live — they're the foundation of clean traffic from day one.
Create a shared negative keyword list with all 50+ terms above. Apply it to every new campaign at launch. This list should grow over time as you mine the search terms report and find new irrelevant categories.
The Search Terms report shows every actual query that triggered your ads. It's your most valuable source of new negative keywords — real data from real users telling you exactly what irrelevant searches are burning your budget.
Negative keywords are powerful — and like all powerful tools, they can be misused. Over-blocking is a silent performance killer that's harder to detect than under-blocking.
| Mistake | What It Causes | The Fix |
|---|---|---|
| Adding "free" as broad negative when you offer a free trial | Blocks "free trial CRM" — your best transactional queries | Add "[free CRM]" as exact negative, not "free" broadly |
| Blocking competitor brand names in competitor campaigns | Defeats the purpose of the entire campaign | Competitor campaign gets their own exclusion list |
| Using broad negatives for product features | Blocks queries like "CRM analytics" when you have analytics features | Use phrase or exact negatives for nuanced terms |
| Never reviewing the negative list | Old negatives may block newly relevant queries after business pivots | Audit the full negative list quarterly |
Las keywords positivas le dicen a Google para qué búsquedas mostrar tus anuncios. Las keywords negativas le dicen a Google qué búsquedas excluir activamente. Sin ellas, tus anuncios aparecerán para búsquedas técnicamente relacionadas con tus keywords — pero completamente irrelevantes para tu negocio.
Ejemplo: Vendes software CRM premium. Pujas por "software CRM." Sin negativos, tu anuncio aparece para "software CRM gratis," "tutorial de software CRM," "software CRM código abierto GitHub" y "empleos software CRM." Cada clic de esas consultas irrelevantes cuesta dinero y aporta cero intención de compra.
Para la mayoría de cuentas con concordancia amplia o de frase, el 15–30% del gasto total va a consultas irrelevantes durante los primeros 30 días. Una gestión agresiva de negativos en el primer mes suele reducir el gasto desperdiciado a menos del 5%.
Los negativos de frase ofrecen el equilibrio correcto entre cobertura y precisión para la mayoría de situaciones. Usa negativos amplios para palabras únicas universalmente irrelevantes (como "empleos" o "gratis"). Usa exactos cuando necesites bloquear una consulta específica sin bloquear variaciones relacionadas.
| Nivel | Dónde Se Añaden | Alcance | Mejor Para |
|---|---|---|---|
| Nivel de Campaña | Configuración de Campaña → Keywords Negativas | Bloquea en todos los grupos de esa campaña | Exclusiones universales — "gratis," "empleos," "tutorial" |
| Nivel de Grupo | Grupo de Anuncios → Keywords Negativas | Solo bloquea dentro de ese grupo específico | Prevenir que el tráfico de un grupo "robe" otro |
| Lista Compartida | Herramientas → Listas de Keywords Negativas | Aplica una lista a múltiples campañas a la vez | Lista maestra universal aplicada a todas las campañas |
Estos negativos son irrelevantes para prácticamente todas las cuentas comerciales de Google Ads. Añádelos antes de que arranque tu primera campaña.

| Error | Qué Causa | La Solución |
|---|---|---|
| Añadir "gratis" como negativo amplio cuando ofreces una prueba gratuita | Bloquea "prueba CRM gratis" — tus mejores consultas transaccionales | Añade "[CRM gratuito]" como exacto, no "gratis" en amplio |
| Bloquear marcas de competidores en campañas de competidores | Anula el propósito de toda la campaña | La campaña de competidores tiene su propia lista de exclusión |
| Negativos amplios para funcionalidades de producto | Bloquea "CRM analítica" cuando tienes funciones de analítica | Usa negativos de frase o exactos para términos matizados |
| No revisar nunca la lista de negativos | Negativos antiguos pueden bloquear consultas relevantes tras pivots de negocio | Audita la lista completa de negativos trimestralmente |
