Descriptions bring clicks. Strategy converts them.
In a diagnostic call, we map your full YouTube acquisition system: topics, titles, descriptions, and the path from viewer to customer.
How it works
Paste your video URL
Drop in any YouTube video link and the landing page you want to drive traffic to. Two fields. Under 10 seconds.
We analyze your video
We fetch your video's title, existing description, and transcript. Then AI generates an optimized description with accurate timestamps based on your actual content.
Copy and publish
Copy the full description with one click. Paste it into YouTube Studio. Your CTA link already has UTM parameters so you can track traffic from each video.
Above the fold (first 150 chars)
"Best CRM for small business? We tested 5 options head-to-head."
Wasted above the fold
"In this video, I talk about CRM tools and share my thoughts..."
Why the first 150 characters of your YouTube description matter more than the rest
YouTube only shows the first 150 characters of your description below the video. Everything else is hidden behind the "Show more" link. That means only 150 characters are doing any work for you by default. The rest requires a deliberate click.
For business channels, those 150 characters need to do two things. First, include your target keyword so YouTube's algorithm understands what your video is about. Second, include a link to your website or landing page so interested viewers can take the next step without scrolling.
The majority of YouTube descriptions start with "In this video, I talk about..." which wastes the entire above-the-fold space on a sentence that says nothing. The viewer already knows what the video is about from the title. Your description's first sentence should add something the title could not: a specific hook and a clear path to learn more.
This tool generates the above-the-fold section separately from the full description. It shows you the character count so you know exactly what viewers will see before "Show more." No guesswork, no wasted characters.
YouTube description best practices for business channels
Writing a YouTube description is not the same as writing a blog post or social media caption. YouTube descriptions serve three audiences: the algorithm, the viewer, and Google Search (which also indexes YouTube descriptions). Here is what matters for each.
Put your keyword in the first sentence
YouTube weighs early words more heavily for ranking. If your target keyword is "best CRM for small business," it should appear in your first sentence, not buried in the third paragraph. This tool places the keyword in the above-the-fold hook automatically.
Place your CTA link above the fold
Your most important link belongs in the first 150 characters. A viewer reading your description is already interested. They clicked on your video. They started reading your description. That is buying intent. Do not make them scroll to find your link.
Use timestamps to boost click-through rate
YouTube displays timestamps as clickable chapters in the video player and in search results. Chapters make your video look more professional and help viewers find the section they care about. Videos with chapters tend to get higher click-through rates from search because the viewer can see the video covers their specific question. Our YouTube SEO guide covers how timestamps, descriptions, and tags work together for ranking.
Write 200-500 words, not 50
Many business channels write 1-2 sentences and a link. That is a missed opportunity. YouTube uses your description text to understand your video content and match it to search queries. More relevant text means more keyword signals for the algorithm. Aim for 200-500 words that expand on the video topic and naturally include keyword variations.
Include 5-8 relevant tags
Tags carry less weight than titles and descriptions, but they help YouTube understand your content category. Use your target keyword, 2-3 variations, and your brand name. Avoid stuffing 30 generic tags. Quality matters more than quantity.
What this description generator does differently
Generic YouTube description generators produce a block of text and leave you to figure out formatting, keyword placement, and structure. This tool is built specifically for business channels that use YouTube to drive website traffic and customer acquisition.
How this tool compares
| Feature | Typical generators | SellOnTube |
|---|---|---|
| Analyzes your actual video | No | Yes, via transcript |
| Above-the-fold optimization | No | Yes, with character count |
| CTA link with UTM tracking | Manual | Automatic |
| Timestamps | Not included | From transcript |
| Tags | Not included | 8-12 relevant tags |
| Built for | Creators | Business channels |
The tool outputs four separate sections instead of one block of text. The above-the-fold hook is written and measured independently because it is the only part most viewers will read. The full description body is optimized for keyword density without sounding robotic. Timestamps are generated from your video's actual transcript, not guessed from the title. Tags are selected for relevance, not volume.
The "Copy Full Description" button combines all four sections into a single formatted block you can paste directly into YouTube Studio. No reformatting needed.
Frequently asked questions
Is this YouTube description generator free?
Yes. You get 3 free generations without any signup. After that, enter your business email to continue generating descriptions at no cost. There is no paid tier and no feature gating.
How long should a YouTube description be?
YouTube allows up to 5,000 characters. For business channels, aim for 200-500 words in the full description. The critical part is the first 150 characters (above the fold), which is all viewers see before clicking "Show more." This tool optimizes that above-the-fold section separately so nothing gets wasted.
Do YouTube descriptions affect SEO?
Yes. YouTube uses descriptions to understand what your video is about and match it to search queries. Keywords in your description help YouTube surface your video in search results and suggested videos. The first 2-3 sentences carry the most weight for ranking. Google also indexes YouTube descriptions, so a well-written description can help your video appear in Google search results too.
Should I put links in my YouTube description?
Yes, and placement matters. Your most important link belongs in the first 150 characters, before the "Show more" fold. Viewers who check your description are showing buying intent. Make it easy for them to reach your website without scrolling. This tool places your CTA link in the above-the-fold section automatically.
Do timestamps and chapters help with YouTube SEO?
Yes. YouTube can display timestamps as chapters in the video player and in search results. Chapters increase click-through rate from search because viewers can see the video covers their specific question. They also improve watch time because viewers can jump to the section they care about instead of bouncing. This tool generates suggested timestamps that you can adjust to match your actual video.
What tags should I use on YouTube?
Tags have less ranking impact than titles and descriptions, but they still help YouTube understand your content. Use 5-8 tags that are specific to your video topic. Include your target keyword, variations of it, and your brand name. Avoid stuffing 30+ generic tags. This tool generates relevant tags automatically based on your video topic and target keyword.
Does this tool use AI to write descriptions?
Yes. The tool uses AI to analyze your video's title, existing description, and transcript. It then generates an original description optimized for YouTube search and click-through. The AI writes the above-the-fold hook, full description body, and suggested tags. Timestamps are extracted from the transcript, not generated.
