  • Keep your customer personas organized and readily available for your team by saving them to Google Drive.

Useful AI skills that will drastically improve your customer avatars 

The instructions in this post are based on one topic Mercer covered in an AI training. 

This schematic overview gives you a quick understanding of where the process of creating avatars fits in the bigger picture of gaining powerful AI skills. 

To get the most out of this guide, I recommend you watch the video or read the instructions first. 

They will give you a good grasp of what is possible with AI by applying Mercer’s expert advice like: 

When prompting Gemini, focus on the outcome you desire for your customer avatar, rather than getting bogged down in explaining the ‘how' to the AI.

Then, you can best watch this extensive Gemini workshop to dive deeper into the exact techniques Mercer invented and demonstrates.

How to create a customer avatar with Google Gemini?

Step 1: Copy your Deep Research avatar instructions

Copy the Gemini Deep Research instructions to create your ideal customer profile.

Step 2: Use Gemini Flash, Flash Thinking or Pro for your prompt

Start a new chat in Gemini that uses another model than Deep Research. Attach the instructions from your research (step 1) and prompt AI to create your avatar. 

Pro tip: As Mercer shows, you can best ask AI to create different personas. That will give you later a much broader perspective on your marketing efforts.

Step 3: Review and improve your prompt

Although Gemini does the heavy lifting, you always need to review prompts before executing them. If needed, adapt them.

Mercer wrote two super prompts to do this “What’s the best result prompt” and “Create the better result” prompt.

Step 4: Review the AI output

The next step is to instruct Gemini to “pretend” it got details of our target audience. That saves you tons of time. 

Don’t forget to check if the output matches your desired result. 

Step 5: Save your avatars to Google Drive

The last step is to save each customer avatar in a separate Google Doc. That will make it easier to access them later or even share them with your team members.

And that’s it. Instead of guessing, you used Gemini to create detailed drafts for several avatars. 

What to do after creating your first customer personas with AI?

You've now witnessed how to go from your initial research to tangible customer avatars using the speed and power of Google Gemini. 

But the journey doesn't end here! In Part 3 of our series, we'll take these AI-generated avatars and explore advanced techniques for refining them and even getting direct feedback from our AI customer focus group. 

This final step is where you'll turn your good avatars into truly exceptional marketing assets.

Answers to your common questions about developing customer avatars in Gemini

What's the benefit of creating multiple buyer personas?

Creating multiple buyer personas allows you to represent different segments or key types within your ideal customer base. This helps you tailor your marketing messages and strategies more effectively to resonate with each specific group.

What Gemini model should I use to generate customer avatars? 

Although you can start with a simple prompt, you will get the best results by combining Deep Research and any of the other Gemini models. It's worth experimenting to see which model provides the best results for your specific needs. Keep in mind that the models (Flash, Flash Think, Pro) are constantly improving and that results may vary over time.
