Prompt by role: turn DeepSeek into an SEO, content and ads expert for each campaign

To get the best performance out of DeepSeek, you need to understand role-based prompting. This technique makes DeepSeek act as an expert, so the tool produces specialized content.

That content fits each area of your marketing. It ensures high accuracy and makes the output more useful for every SEO, content or advertising campaign.

The Role-Play Prompt technique delivers 80% better results

The Role-Play Prompt technique assigns DeepSeek a specific role. You turn it into an expert, for example an SEO specialist or an experienced content creator.

This technique steers DeepSeek. It helps the AI give deeper analysis and suggestions, so the output is higher quality. Many users have noticed improvements of up to 80%.

This approach keeps DeepSeek focused and cuts out unnecessary information. At the same time, it adds expertise to every response. That matters a lot.

Example prompt for SEO and keyword research

When you need DeepSeek's help with SEO, put it in the role of an expert. Here is a concrete example:

• Sample prompt: “You are an expert SEO with 10 years of experience. My business is in warehouse management software. List 10 main keywords and 20 secondary keywords with high potential for the Vietnamese market in 2026. Also analyze the search intent for each keyword group.”

• Expected result: DeepSeek will give you a detailed keyword list along with an in-depth analysis of search intent. This makes it easy to build your SEO content strategy.

You can also ask DeepSeek to analyze competitors or find niche opportunities. It can help optimize meta descriptions too.

Example prompt for blog and social media content

DeepSeek is also a capable assistant for creating content. Let's try it in the role of a content expert:

• Sample prompt: “You are a content marketing specialist with 7 years of experience. My business provides website design professional services. Outline 5 blog post ideas about website trends in 2026. Each idea needs a compelling title and 3-5 key points. Also write 3 short posts for Facebook and LinkedIn from one of the ideas above.”

• Expected result: DeepSeek will return structured blog post ideas along with optimized social media posts. This saves a significant amount of planning time and keeps your brand voice consistent.

You can refine the role. Add specific requirements, and DeepSeek will respond accordingly.

The 3-layer prompt formula: Extract market and customer insight from raw data

To let DeepSeek make full use of its logical processing, you need a clear prompt structure. We distilled a formula: “Context, Data, Analysis”. It is how DeepSeek understands your request correctly and returns sharp results.

This formula turns scattered information into valuable perspectives. It forces DeepSeek to follow a coherent line of thought, so you get real insight instead of a generic summary.

Building the “Context, Data, Analysis” prompt framework

The 3-layer prompt framework starts with “Context”. You need to define DeepSeek's role and the goal of the analysis. Picture DeepSeek as a marketing expert, with a very clear goal.

Next comes “Data”. This is where you provide all the raw information. It can be a spreadsheet, text or a list. What matters is that the data is complete.

Finally, “Analysis” tells DeepSeek how to process the data. You specify the output format and list the points to watch. The result will be more accurate. MONA applies this in its internal automation software.

Here is an example prompt structure:

< Context>

• You are a market analyst at an F&B company.
• Goal: Extract the main pain points and hidden wishes from customer feedback.

< Data>

• [Paste all customer comments, surveys or product reviews here]

< Analysis>

• List the 5 most common pain points.
• List 3 customer wishes that are not yet met.
• Suggest 2 product improvement ideas.
• Format the output as a table with the columns “Pain point/Wish”, “Priority (High/Medium/Low)” and “Suggested improvement”.

Using customer feedback analysis to find pain points

Customer feedback is a goldmine of insight. But reading thousands of comments yourself takes a lot of time. DeepSeek solves this problem.

Gather all the comments from your website, social media and email. Then paste them into the “Data” section of the prompt. This step is important.

Ask DeepSeek to identify negative keywords and phrases that express disappointment, and to look for suggested improvements. The analysis will point out clear pain points. MONA has trained its team to use DeepSeek for SEO and content optimization very effectively.

Specific example prompt:

< Context>

• You are the customer experience manager of a coffee shop chain.
• Goal: Identify common problems and unmet expectations among customers.

< Data>

• “Coffee is too sweet, not enough ice”, “Service is slow, long wait”, “Noisy space, hard to work”, “Want more kinds of pastries”, “Price is a bit high for the quality”, “Weak Wi-Fi, keeps dropping”.

< Analysis>

• Summarize the customers' main pain points.
• Group the pain points into “Product”, “Service” and “Space”.
• Suggest 3 improvement solutions for each group.
• Format the output as clear bullet points.

Analyzing competitors with a feature list

Understanding your competitors is the key to gaining an edge. You can use DeepSeek to analyze their strengths and weaknesses. It is an effective approach.

Collect information on competitors' products, services, pricing and marketing strategy. Then list these features in the “Data” section. DeepSeek will process the information.

In the “Analysis” section, ask DeepSeek to compare and give its assessment. It can help you find points of difference, which is a big competitive advantage.

MONA regularly uses AI tools like DeepSeek in its website design and marketing strategy to stay competitive.

Example prompt for competitor analysis:

< Context>

• You are the Marketing Director of a restaurant management software company.
• Goal: Analyze 2 main competitors to find our strengths and weaknesses.

< Data>

• Competitor A: Software X, 500k/month, features: table management, ordering, inventory, basic reports. Outdated interface, slow support.
• Competitor B: Software Y, 700k/month, features: table management, ordering, inventory, mini CRM, delivery integration. Attractive interface, 24/7 support.
• Our software: Software Z, 600k/month, features: table management, ordering, inventory, POS integration, in-depth revenue analytics. Modern interface, fast support.

< Analysis>

• Compare the main features of the 3 products.
• Identify the strengths and weaknesses of Software Z against A and B.
• Suggest 2 positioning strategies for Software Z.
• Format the output as a comparison table with your assessment.

The 1-hour workflow: automate 30 varied ad headlines and descriptions

Our marketing team often spends a lot of time brainstorming and writing ad headlines and descriptions. Keeping them varied and suited to each audience or platform is even harder.

Free DeepSeek is a big opportunity to streamline this process. We share the 3-step workflow below. You can produce dozens of quality ad variations in just one hour of work.

Step 1: Prepare product information and the target audience

Before you start, gather complete information about the product or service. This helps DeepSeek understand the context and produce accurate content.

• Standout features and core benefits of the product.
• Target audience: age, interests, the pain points they face.
• What sets the product apart from competitors.
• The desired call to action (buy, sign up, learn more).

This is like writing a brief for a professional copywriter. The more detail, the higher the quality of the result. brief Step 2: Build the “Create variations” prompt

Step 2: Build the ‘Create variations’ prompt

This is the key step for getting the most out of DeepSeek. You need a clear, structured prompt so DeepSeek understands the request.

You can use this prompt structure:

"You are a marketing expert with 10 years of experience. Your task is to create 30 headlines and 30 creative, varied ad descriptions for [Product/service name]. The product is: [Product description, features, benefits]. Target audience: [Detailed audience description]. Tone: [Playful, professional, urgent, humorous...]. Usage context: [Facebook ads, Google Ads, Zalo Ads...]. Requirements: 1. Each headline is no more than 30 characters and each description no more than 90 characters. 2. Create many variations in angle (for example: focus on benefits, pain points, urgency, promotions). 3. Make sure the content is engaging, attention-grabbing and has a clear call to action. Begin."

Replace the parts in square brackets `[…]` with the information you prepared in Step 1. DeepSeek will quickly return useful suggestions.

Step 3: Iterate and refine for high quality

DeepSeek will give you a batch of first drafts. You need to review and adjust them to ensure quality. DeepSeek doesn't always get what you mean on the first try.

• Read each suggestion carefully and pick the ideas that fit best.
• Ask DeepSeek for more variations based on a few samples you like. For example: “Create 10 more variations of headline number 5 with a friendlier tone.”
• Adjust small details of wording and punctuation to fit the brand voice and the specific marketing campaign.

This iterative workflow gets you a large number of varied ad samples in a short time. Your marketing team can then focus on testing what performs.

Optimizing internal performance: DeepSeek helps your marketing team review and fix its own work

Raising the quality of marketing content is a priority for every business. DeepSeek gives you a useful tool for your team to review and evaluate drafts before publishing. This helps us spot and fix weaknesses proactively, and output quality improves significantly.

At MONA, we also apply language models like DeepSeek in our internal workflow. We use AI to run an initial quality check on SEO articles hay marketing campaign. Our experts then refine them, making sure the content meets the highest standard for clients.

The “Evaluate by criteria” prompt for articles

For DeepSeek to evaluate an article effectively, you need to give it clear criteria. This helps the AI understand what you want and give more accurate feedback. Consider the example prompt below.

You can use a prompt like: “Evaluate this article against the following criteria: (1) Clarity and ease of understanding; (2) Coherence of ideas; (3) Ability to engage readers; (4) Matches the brand voice; (5) Is it optimized for SEO? Article: [Paste the article here].”

Also, always remember to assign the AI a role. For example, “You are an experienced marketing expert. Please evaluate the following article…” This helps DeepSeek give more professional feedback.

Using DeepSeek to detect grammar and style errors

Spelling mistakes, grammar errors and inconsistent style can hurt your content's credibility. DeepSeek is a capable helper for reviewing and catching these errors. Take advantage of the AI's language ability.

A simple way is to use this prompt: “Check this article for grammar errors, spelling mistakes and awkward sentences. Suggest fixes so the writing reads smoothly and professionally. Article: [Paste content].”

DeepSeek will save your team significant time on proofreading. We can focus on creating big ideas instead of fixing small details.

Suggesting content improvements based on campaign goals

Every piece of marketing content needs to serve a specific goal. DeepSeek can analyze your content and suggest improvements. This keeps your content aligned with the goals you set.

For example, if the goal is to increase newsletter sign-ups, you can prompt: “This article aims to increase the newsletter sign-up rate. Suggest ways to improve the call to action (CTA) and make the content more appealing to potential readers. Article: [Paste content].”

DeepSeek can also suggest better website structure or landing pages. In turn, it improves the user experience and helps your campaign reach peak performance.

When free DeepSeek hits its ceiling: upgrade your marketing chain with production automation software

Free DeepSeek delivers great value. It is a capable support tool for many marketing tasks. You and your team can use DeepSeek to brainstorm and outline content, and it writes first drafts quickly. However, the tool still has clear limits. We need to recognize them to optimize our long-term strategy.

Where free DeepSeek stops: see the hidden costs

Although DeepSeek offers many free benefits, it is not a complete solution. The free version usually limits the number of uses or premium features. That forces you to weigh the cost of upgrading or look for other tools. Relying on many separate tools creates hidden costs. Your team loses time switching between platforms, and every tool has a different interface and way of working. That cuts productivity significantly.

DeepSeek, or any single AI tool, only solves part of the workflow. It helps with content creation but cannot manage the whole marketing chain. You will need more tools for analytics, distribution and customer management. All of it adds up to a patchwork chain, which carries many risks.

Scattered data: the enemy of automated marketing performance

Another big challenge is data fragmentation. When you use many different tools, your marketing data ends up scattered. Customer information, campaign performance and cross-channel engagement are hard to pull together. You lose the big picture, which gets in the way of timely decisions. We can't analyze deeply enough to optimize. Scattered data also raises the risk of errors, and protecting customer information becomes a problem too.

A patchwork marketing chain can't scale. It depends too heavily on manual work, and return on investment (ROI) drops as a result.

The MONA automation chain: where AI becomes a combined force

To fully solve these limits, MONA develops production automation software. We don't sell AI tools one by one. Instead, we build closed-loop chains of modules. This software integrates AI deeply into your entire marketing workflow. DeepSeek and other advanced AI models are just the means that unlock it. They let machines do work that takes thinking and creativity.

MONA's software keeps data seamless. All information is centralized and secure. You get an overview of every campaign. The marketing workflow, from ideation and content production to distribution, is automated. This cuts manual work significantly, and your team's output multiplies.

With over 10 years of experience and a team of 60+ staff, MONA has built systems for 14,000+ projects. Together we are heading toward an automated marketing future.
