Why YouTube Descriptions Matter for SEO and Engagement

Before we jump into the AI-powered process, here’s why YouTube descriptions are important:

SEO Boost: Well-crafted descriptions help videos rank higher for relevant search terms

More Clicks and Views: A clear and engaging description helps viewers understand the content before clicking

Better Discoverability: YouTube uses descriptions to categorise and recommend videos

Saves Time: AI can generate structured descriptions faster than manual writing

Dominic explains, "YouTube descriptions aren’t just a formality but they also play a huge role in search visibility. A well-structured description can improve rankings, encourage engagement and particularly as we've seen in the Trout Tales Tasmania video case study, even drive conversions.

"The problem is, most creators don’t have the time to write optimised descriptions for every video.... and AI simplifies this process."

Step 1: Transcribe Your Video with Descript AI

Why Use Descript AI?

Among it's many other uses, Descript AI is a transcription tool that automatically converts speech into text.

It also allows users to edit video and audio by editing the transcript, making it useful for content creators.

How to Use Descript AI for Transcription

1. Upload Your Video – Drag and drop your YouTube video file into Descript AI
2. AI Transcription Begins – Descript will generate a transcript of your video
3. Edit & Clean Up – Remove filler words like “um” and “uh” using Descript’s built-in tools
4. Copy the Transcript – Once refined, copy the transcript to use in the next step

Dominic adds, "Descript AI doesn’t just transcribe—it lets you clean up and refine content before moving to the next stage. This removes the need to manually listen and type out everything, which is a massive time-saver."

Having a clean transcript makes the next step of generating a YouTube description much easier and with just a few additional steps, you can transform this text into a well-structured description ready for publishing.

Step 2: Generate an Optimised YouTube Description with ChatGPT

Now that we have the transcript, we’ll use ChatGPT to format and optimise it for YouTube.

How to Use ChatGPT for YouTube Descriptions

1. Open ChatGPT (or another AI tool like Jasper)
2. Input Prompt: Copy-paste the transcript and prompt ChatGPT with:

"From the transcript provided, generate an engaging YouTube description based on the transcript below. Make it SEO-friendly and structured."

1. Refine & Edit: Adjust the description as needed for clarity and engagement
2. Optimise for SEO: Ask ChatGPT to include target keywords (e.g., “fly fishing Tasmania,” “AI transcription”)

To speed up this process even further, you can create a Custom GPT that understands your preferred format, tone, and style.

This eliminates the need to prompt ChatGPT from scratch every time, allowing you to generate descriptions that are consistently structured and on-brand with minimal input.

"This step is where AI really helps," says Dominic. "Instead of starting from scratch, you get a structured draft that’s already close to what you need. You can tweak it to fit your style, but most of the work is already done."

"Particularly here with our clients at Wakeford Digital, we also find that using the transcript to generate the descriptions helps add personal inflections, tone, terminology and references into the content - helping it to stand out or not sound robotic."

Using ChatGPT ensures that your descriptions are engaging and informative while also being SEO-friendly.

Now with the textrefined, it’s time to focus on optimising titles and calls-to-action.

Step 3: Enhance with Clear Titles & Call-to-Actions

Optimise Your Title for Clicks

Ask ChatGPT:

"Generate five title variations using the transcript."

Examples:

• "A Guide to Fly Fishing in Tasmania – Key Tips and Insights"
• "Avoid These Common Fly Fishing Mistakes"

Add Call-to-Actions (CTAs)

A strong description should include a call-to-action to encourage viewer engagement. Examples:

• "Subscribe for more fishing updates"
• "Like & comment with your top fishing spots"
• "Check out our gear recommendations here: [link]"

Adding a well-thought-out title and CTA can make your video more appealing to viewers, increasing engagement and retention. AI-generated descriptions allow you to structure these elements effectively without spending extra time crafting them manually.

Step 4: Format and Upload the Description to YouTube

Now that your description is ready, upload it to YouTube:

1. Paste into YouTube – Add the description under your video
2. Use Formatting: Add bold keywords, line breaks, and bullet points for readability
3. Include Links & Hashtags: Example: #FlyFishing #TasmaniaFishing #FishingTips
4. Save & Publish

Formatting ensures that your description is easy to read and visually appealing. This final step ensures your video is well-presented and optimised for search and engagement.

Final Thoughts

Using AI tools like Descript AI and ChatGPT can significantly reduce the time it takes to create compelling, SEO-friendly YouTube descriptions.

With a clear workflow in place, content creators can focus on producing high-quality videos rather than spending unnecessary time writing descriptions manually.

Custom GPT models can also make this process even more seamless by providing structured outputs that match your preferred format.

By implementing this AI-driven approach, you ensure that your YouTube content is both accessible and optimised without requiring additional resources. This method not only saves time but also improves your video’s visibility, engagement, and overall impact.
