Advanced Prompt engineering for SEO content: the guide to unique results with AI

From generic content to Google mastery

The artificial intelligence (AI) has gone from being a novelty to an essential tool in digital marketing. However, in a world where thousands of agencies and brands use chatGPT on a daily basis, the question is no longer whether to use AI, but how to use it so as not to sound generic. If your AI-generated content seems «flat,» repetitive or fails to rank, it's not the tool that's the problem, it's the quality of your content. prompt engineering.

He prompt engineering (PE) is the art and science of communicating with language models (LLMs) to direct their output towards specific, high-value targets. In SEO, this means transforming a simple «write an article about digital marketing» into a sophisticated and optimised content plan.

At karmina, we have already explored in depth the impact of AI on positioning in our article [Artificial intelligence as the new frontier of SEO: an advanced guide for marketing agencies].. Now, we move up a level. This guide does not deal with basic commands; it is a advanced manual for your team to turn AI into a true co-creator of unique content that complies with the standards of E-E-A-A-T (experience, expertise, authority and trustworthiness) of Google.

The failure of the standard prompt: why don't you position?

Most marketers make a fatal mistake: their prompt is a command, not a detailed instruction.

The generic prompt (low value example):

“Write me 5 compelling titles about digital transformation.”

The problem: the LLM generates titles that already exist because you haven't provided it with the context, the audience, the tone, nor the search intent (search intent). The result is content that clutters the internet, offers no unique perspective and is immediately penalised by Google's algorithms for originality.

The solution lies in the task decomposition. We must feed the AI with the same parameters that an expert human SEO copywriter would use.

The CPTF methodology: the advanced prompt engineering framework for SEO

To ensure that every interaction with chatGPT or a similar model generates value, we have developed the framework CPTF (context, person, task and format). Always apply these four pillars to your prompt teacher.

C: context and objective (context and goal)

Before anything else, define the why. What is the intention to search (informational, transactional, navigational) of the user?

Key question: What problem does this content solve for the reader and at what stage of the funnel (sales funnel) is located?
Example of context: «The aim is to position for the keyword main ‘local SEO tools in barcelona’ with an informative and comparative search intent, aimed at SME owners».»

P: person and tone (role and tone)

Assign the AI a role of authority. This is the crucial point that raises the E-E-A-T quality of the content.

Key question: Who should be the ideal author of this content?
Example of a person: «He acts as a senior SEO consultant in a digital marketing agency with 10 years of experience in the Barcelona market, using a professional, didactic tone with a touch of subtle humour.»

T: task (specific action and constraints)

The task should be a list of specific actions, not a vague request. This includes SEO constraints.

Essential task constraints:
- Keyword density: mention the keyword (KWP) at least 6 times.
- Secondary keywords (LSI): include semantically related terms.
- Length: specify the number of words.
- Data and links: instruct the AI to leave gaps for data and references (the human touch!).
- Example of a task: «Write a 1500-word draft. The KWP should appear in the title, meta-description and at least 3 h2 subheadings. Be sure to include and link to the LSI terms: ‘business geolocation’, ‘Google my business 2025’ and ‘hyperlocal strategy’.»

F: format and output (output structure)

Define exactly how you want to receive the content. If the format is a draft for a blog post, ask for a perfect SEO structure.

Perfect SEO structure: H1 title, meta-description, introduction (with KWP and hook), subtitles (H2), key points (H3), summary (takeaways) and a conclusion with a call to action (CTA).

Practical examples of advanced prompts

Below are templates that use the CPTF framework for specific tasks that any agency needs to perform:

Example A: Niche analysis and cluster of content

This prompt helps the AI to think strategically, rather than just writing a post.

[PERSON] [PERSON] [PERSON] [PERSON] [PERSON] [PERSON] [PERSON] [PERSON] [PERSON] You are an expert in SEO, with the authority of an chief marketing officer.

[CONTEXT]. We are launching a cluster of content on ‘360º strategy’. The main KWP is ‘360º digital marketing’. The intention is informative and to generate leads.

[TASK] [TASK] [TASK] [TASK] [TASK Analyse this KWP and generate 5 H2 subheadings that function as pillar articles within the KWP. cluster. For each H2, give me 3 possible secondary KWPs (long-tail) and a unique angle for the content.

[FORMAT] [FORMAT] [FORMAT] [FORMAT] [FORMAT] [FORMAT] [FORMAT Displays the results in a 3-column markdown table (H2 pillar, 3 secondary KWPs, single angle).

Example B: High-performance SEO draft (using full CPTF)

This is the prompt teacher for the creation of an article, such as this one you are reading.

[PERSON] [PERSON] [PERSON] [PERSON] [PERSON] [PERSON] [PERSON] [PERSON] [PERSON] You are an SEO copywriter and content marketing specialist at Karmina. You have the ability to synthesise complex information into didactic and highly optimised texts.

[CONTEXT]. The article is for our blog. KWP is ‘advanced prompt engineering’. The audience is business owners and marketers who already use AI but need to improve the performance of their content.

[TASK] [TASK] [TASK] [TASK] [TASK Create a full 1600-word draft. I need:

A persuasive H1.
A meta description of 155 characters.
An introduction that engages and raises the issue.
Develop the main section detailing the CPTF framework (context, person, task, format).
It includes 3 examples of prompts practical (as in example A and B).
INCLUDES AN ETHICS SECTION on human review.
Make sure the tone is professional and empathetic.
In the text, you refer to ‘visual AI tools, such as chatGPT with images, are speeding up production’.

[FORMAT] [FORMAT] [FORMAT] [FORMAT] [FORMAT] [FORMAT] [FORMAT Deliver only body text structured with H1, H2, H3 and bold for keywords.

The human touch: E-E-A-T, data and final editing

The best strategy for prompt engineering in SEO stops when the AI model finalises its draft. The AI has no real experience. To meet Google's rigorous standards (E-E-A-T), human intervention is essential:

Data verification: AI often «hallucinates» with figures and statistics. Your team must verify every fact, study or quote.
Add experience (E-E-A-T): insert case studies, personal opinions, screenshots of the agency's own results or examples real that only karmina can provide. This is what Google rewards!
Authoritative external links: high quality content referencing credible sources. Insert links to market research, industry reports, or to Google's official guidelines on quality of content and E-E-A-T.

By combining the efficiency of AI through advanced EP with human validation, expertise and ethics, your agency will not only produce more content, it will generate authoritative content that really positions.

Conclusion

He prompt engineering is the difference between competing for residual traffic and dominating search results. By implementing the CPTF and maintain the human touch in the final review, your karmina agency will position itself as a leader in strategic AI integration.
