As the digital marketing landscape continues to evolve, AI-powered language models have transitioned from being a mere novelty to an indispensable tool for optimising operations and enhancing strategies. With the introduction of ChatGPT 4, the industry is witnessing a revolution, as this cutting-edge AI model surpasses its predecessor, ChatGPT 3.5, in various tasks.

Join me as I explore the fascinating world of ChatGPT 4, unveiling its full potential and demonstrating how it outperforms ChatGPT 3.5 in various digital marketing applications, including answering questions, providing creative recommendations, analysing datasets, and generating code.

Ability to answer general digital marketing questions

I asked both ChatGPT 3.5 and 4 to answer the question: 

“Could you please explain to me in simple words the difference between Universal GA and GA4?”

Here are the results:

ChatGPT 4:

The first notable distinction between the two results is that ChatGPT 4 begins its response by affirming its intention to use straightforward language.

This subtle enhancement in ChatGPT’s feedback significantly improves the overall user experience, as it reassures that the guidelines outlined in my prompt have been acknowledged and adhered to.

ChatGPT4’s introduction is considerably more concise than GPT3’s, clearly explaining the two Google Analytics versions in just one sentence.

Additionally, ChatGPT4 offers a more thorough comparison of the two GA versions by including an insightful point about the integration of Google Ads in GA4.

Ability to come up with digital marketing creative recommendations

What happens when we ask both GPT versions to come up with SEO strategy recommendations with the below prompt:

“Can you please define an SEO strategy for my website? I sell health supplements.”

ChatGPT 4:

When asking both GPT versions for SEO strategy recommendations, ChatGPT 4’s response is more structured, detailed, and comprehensive, covering a broader range of SEO aspects and offering a more actionable strategy for a health supplement website.

ChatGPT 4’s response is easier to follow with clearly defined sections and subheadings. It provides a more comprehensive SEO strategy, offering additional details and recommendations, such:

  • local SEO
  • influencer marketing
  • online directories

While both versions cover on-page and off-page optimization, ChatGPT 4 delves deeper into technical SEO aspects like site speed, mobile-friendliness, secure connections, XML sitemaps, and schema markup.

ChatGPT 4 suggests a wider variety of content types, including videos and infographics, whereas ChatGPT 3.5 mainly focuses on blog posts and product descriptions. Both responses emphasize the importance of keyword research, but ChatGPT 4 specifically mentions targeting both short-tail and long-tail keywords.

ChatGPT 4 emphasises on monitoring and analyzing website performance and adjusting strategies accordingly, while ChatGPT 3.5 briefly mentions using analytics tools..

Ability to comment on datasets

In my next prompt, I asked ChatGPT the following:

I would like you to comment on the below data coming from my Google Search Console account showing the 100 most clicked keywords in the last 28 days. My goal is to identify keywords that could benefit from on-page optimisations to rank higher.

I then pasted the 100 keywords data and hit enter.

ChatGPT 4:

Both GPT3.5 and GPT4 provided valuable insights into the keyword data I provided. However, there were noticeable differences in the quality and focus of the responses.

GPT3.5 provided a more general analysis of the keywords and offered strategic suggestions for on-page optimizations. It focused on identifying keywords based on their click-through rate, the presence of “price” or “cost” terms, dog breeds and health issues, and long-tail keywords with a high click-through rate. 

GPT4, on the other hand, focused on specific keywords and their corresponding average positions and click-through rates. It identified ten keywords that could benefit from on-page optimizations to rank higher. 

GPT4’s response was more actionable. It listed specific keywords to optimize and provided a brief overview of content optimization techniques like improving page titles, meta descriptions, header tags, and multimedia elements.

Since I was looking for actionable insights and specific keywords to optimise my content for, ChatGPT 4 has provided a much better response here.

Ability to code properly

I have minimal knowledge of programming languages. I used ChatGPT to help me code a WordPress plugin last year, and I was very impressed with the results. Let’s check how the two versions compare when it comes to code with the below prompt:

For my WordPress website, I wish to create a visually appealing and user-friendly calculator tool to allow my audience to calculate how much they should spend on SEO services monthly based on their monthly website revenue and total marketing budget.

The calculator should be Gutenberg Block Editor WordPress-friendly so I can copy and paste it into an HTML block to make it work. Users should input their monthly website revenue and total marketing budget, and the calculator should provide a range of recommended SEO budgets.

The low part of the range would be ideal for maintaining the current SEO performance, the middle part would be constant SEO growth, and the highest would be significant SEO growth.

The calculator should display the results as a range in the form of percentages or monetary values and include clear labels and instructions to help users understand the recommendations.

For the SEO budget calculation, the recommendations should be based on the following:

1. Protect current SEO performance:

Focus on basic activities such as on-page optimisation, content updates, and technical SEO to maintain your current SEO performance. A budget of 5-10% of your total marketing budget or 1-3% of your website revenue could be sufficient.

2. Gradual organic growth:

Invest in more advanced SEO strategies, like content development, link building, and user experience improvements for moderate growth. Allocate 10-20% of your marketing budget or 3-6% of your website revenue to expect SEO growth.

3. Substantial organic growth:

You should invest in comprehensive SEO campaigns and long-term strategies to achieve significant growth. This includes extensive keyword research, competitive analysis, and content marketing. Consider allocating 20-40% of your marketing budget or 6-12% of your website revenue to SEO activities.

Please ensure that the calculator meets these requirements and is easy to use and understand for my audience.

ChatGPT 3.5:

ChatGPT 4:

GPT-3.5 and GPT-4 have provided responses that attempted to address my request. However, there are some differences in the quality and usability of the responses.

The GPT-3.5 response provided an HTML, CSS, and JavaScript code snippet for creating a calculator that aligns with my requirements.

The design and structure of the code were easy to understand, with separate sections for HTML, CSS, and JavaScript. However,  the provided code did not work when the “Calculate” button was clicked.

The main issue with the GPT-3.5 response is that the text of the provided response was cut off at the end, which left the code snippet incomplete. I asked it to complete it, and the code ended up working:

The GPT-4 response provided a complete and functional code snippet, including HTML, CSS, and JavaScript. The code looked organized and formatted correctly. It worked as expected when the “Calculate SEO Budget” button was clicked as shown in the screenshot above. The results are displayed according to the ranges and percentages I specified in my requirements.

However, the current design is minimal and functional, and it could be enhanced to provide a more visually appealing and user-friendly experience for users. I know that I could easily get GPT4 to propose visual enhancements by proposing CSS edits.

While both responses attempted to address your requirements, the GPT-4 response provided a more complete and functional solution. The GPT-3.5 response contained some issues that made the code non-functional, although, with minor adjustments, it could also work as expected.

In terms of quality, the GPT-4 response was superior due to its functionality and organization, but both versions had merits. The GPT-3.5 response demonstrated a clear understanding of the requirements. It also provided a well-structured response, while the GPT-4 response successfully delivered a working solution that could be implemented on a WordPress website.

I would say it was an even match in this case.

Conclusion: Is It worth paying for the $20 subscription to get early access to ChatGPT 4?

After thoroughly comparing the responses of ChatGPT 3.5 and ChatGPT 4, it’s clear that the GPT-4 model is a significant improvement over its predecessor. There are, however, some observations to consider:

GPT4 responses tend to be slower than GPT3.5, which could be a downside for those who value response speed. However, this slower performance may be an acceptable trade-off for the higher quality output.

GPT4 prioritises resource efficiency, especially when it comes to generating code. This is evident in how it often provides precise instructions to users rather than rewriting the entire piece of code. This approach could benefit those who want to save time and resources on their projects.

GPT4 facilitates creative thinking, making it an invaluable tool for users seeking innovative ideas or assistance in brainstorming.

Based on these observations, the choice ultimately comes down to your individual needs and priorities.

Suppose you accept a slower response time in exchange for higher-quality results and resource efficiency. In that case, the $20 subscription for early access to ChatGPT 4 may be well worth the investment. 

Moreover, if you value creative thinking and need a tool to aid in brainstorming, GPT4 can provide significant benefits over its predecessor. In summary, for many users, the advantages of ChatGPT 4 outweigh the drawbacks, making the subscription a worthwhile investment.
