Choosing a marketing agency can become one of the best investments for a company… or one of its biggest headaches.

Others offer to manage all your social media for less than $10,000 pesos. also you will find freelancers, agencias boutique, consultants independent y large firms con equipos de dozens de people.

Entonces, ¿how saber cuál actually es la right?

La answer no is solely en el price.

is en la structure, la experience y la ability de become en un partner strategic para tu business.

 

1. researches who is behind de la agency

Lo primero que should doing es investigar quiénes son.

• ¿how many years llevan operando?

• ¿Quiénes son sus fundadores?

• ¿Qué tipo de clientes manejan?

Una agency con track record usually tener processes more solid y experience handling different tipos de projects.

 

2. Make Sure It Has a real Team

Today there are many "agencies" that are actually one person coordinating freelancers.

Eso no means que el work vaya a ser wrong, pero sí represents un risk when el project starts a grow.

Una agency established usually has con specialists en different areas such as:

• marketing strategy.

• design gráfico.

3. ask who will do actually tu project

Muchas times who sells no será who executes.

Before signing a contract, ask:

• ¿who will manage mi has?

• ¿who will design mis posts?

• ¿who will take las fotografías o will produce los videos?

• ¿who will optimize las campaigns publicitarias?

• ¿who will respond when exista una emergency?

Knowing the team builds trust and avoids surprises.

 

4. Revisa su portfolio, pero also sus results

A nice portfolio does not always mean an agency generates results.

Ask for real case studies.

• ¿Qué objetivos ayudaron a achieve?

• ¿how much crecieron las sales?

• ¿how many leads generaron?

• ¿how improved el rankings en Google?

Los numbers cuentan una historia a lot more completa que unas a few imágenes attractive.

 

5. evaluate si understands tu industria

No es necessary que has worked con companies identical a la yours, pero sí must demonstrate que understands tu market, a tu client ideal y a tus competitors.

Una agency que researches before de propose usually building estrategias a lot more effective que una que offers exactly el same service para everyone.

 

6. ask how trabaja

A good agency has clear processes.

usually you will find stages such as:

• Initial briefing.

• research y analysis.

• Strategy.

• planning de content.

• production.

• Design.

• execution de campaigns.

• Monthly reports.

• optimization continuous.

Si la answer solely es "publish tres times por semana", probably estás hiring un service operational, no una estrategia de marketing.

7. No choose solely por price

Uno de los mistakes more common es hiring la option more cheap.

El marketing requires specialists, tools, software, production audiovisual, design, analysis y follow-up.

All of that has a cost.

Si una agency offers un service full-service por un price too low, it is worth asking how manages sustain esa operación.

Muchas times you will discover que outsources practically everything o que one person performs todas las functions.

 

8. make sure de que exista una structure

Una good sign es que la agency tenga processes internos defined, tools de management, meetings regular y, de preferably, una office physical donde can meet con el team when sea necessary.

No se is about solely del espacio.

Se is about de demonstrate stability, organization y commitment con sus clientes.

 

9. Analiza how hace marketing para sí misma

A simple question:

If they are marketing experts...

¿they themselves do good marketing?

Review their website.

Their Google rankings.

Their social media.

Their content.

Sus cases de success.

Their digital presence says a lot about the quality of their work.

 

10. Busca una relación de long term

marketing does not work like a switch that you turn on to generate immediate results.

building una marca, posicionarse en Google, optimize campaigns y generate confianza requires time.

Por eso, more que hiring un vendor, busca una agency que can become en un ally strategic para el growth de tu empresa.

 

Señales de alerta before de hiring

If you notice several of these situations, it is worth considering other options:

• They promise guaranteed results in a few weeks.

• No can show cases de success reales.

• No exists un team identified behind de la agency.

• They constantly change staff.

• Everything depends on external freelancers.

• They do not have clear processes.

• They do not provide reports.

• La communication es slow o disorganized.

• Sus social media social y site web están neglected.

Elegir una agency de marketing no debería basarse solely en who charges less.

Una good agency brings estrategia, experience, structure y un team multidisciplinary capable de supporting el growth de tu empresa.

before de sign cualquier contract, researches who is behind de la agency, conoce a las people que trabajarán en tu project, revisa cases de success y make sure de que cuenten con processes solid.

Al final, la mejor agency no es necesariamente la more grande ni la more expensive, but rather la que understands tu business, trabaja con transparency y demonstrates, con results, que can help you a grow.
