Only about 150 characters show before the fold and in search results, so your opening lines have to state what the video delivers and carry your main keyword. Treat them like a second title, not a throwaway.
Everything below the fold helps the algorithm understand what your video is about and which searches to match it to. A few hundred relevant words, with your keyword used naturally, gives you far more to rank on than a single line.
Chapters let viewers jump to the part they want instead of bouncing, and they hand YouTube structured context about your content. Three or more timestamps starting at 0:00 unlock clickable chapters on the progress bar.
A subscribe prompt, your other videos, and your socials turn one view into a follow and a longer session. Keep links relevant and disclose anything affiliate or sponsored.
A great description helps you rank, but the title and thumbnail earn the click. YTGrowth scores all three.

A good description does two jobs at once. The first one or two lines work like a search snippet and a hook, so they should state what the video delivers and include your main keyword naturally, because only the first 150 or so characters show before the fold. Below that, a full description gives YouTube and Google the context to rank you, helps viewers navigate with timestamps, and routes them to your other content, links, and socials. This generator lays out that structure for you so nothing important gets left out.
Use the space. YouTube allows up to 5,000 characters, and longer, well-structured descriptions give the algorithm more context to understand and recommend your video. You do not need to hit the cap, but a few hundred well-chosen words beat a single line every time. Front-load the part that matters (hook plus keyword in the first two lines), then add your summary, timestamps, links, and a subscribe prompt underneath.
Put your main keyword in the first sentence, then use it and close variations naturally two or three more times through the body. Do not stuff it. YouTube reads the description to match your video to searches, so genuine, relevant keyword use helps, while repeating the same phrase ten times reads as spam and can hurt you. Write for the viewer first, then make sure the keyword is present where it fits.
Yes. Adding timestamps (also called chapters) creates clickable chapter markers on the progress bar, which improves the viewing experience and can lift watch time because viewers jump to what they want instead of bouncing. They also give YouTube extra structured context about your content. To enable chapters, the first timestamp must be 0:00 and you need at least three timestamps, each at least 10 seconds apart, which is exactly the format this tool sets up.
The hook, summary, timestamps, and keywords should be unique to each video, because that is the part YouTube reads for ranking and that viewers read to decide. The boilerplate at the bottom (your subscribe line, social links, and recurring resources) can stay the same across videos to save time. The generator separates the two, so you write the unique top fresh each time and keep a consistent footer.
Add three to five relevant hashtags, either at the very end of the description or worked into the text. The first three hashtags in your description appear as clickable links above your video title. Use too many (YouTube counts more than 15 as a violation and may ignore them all) and you weaken the signal, so keep it tight and relevant to the video's topic.
No, links are fine and expected. Adding your socials, a resource list, or affiliate links is standard practice and does not penalize the video. Two notes: disclose affiliate or sponsored links to stay within YouTube and FTC rules, and avoid linking out so aggressively that you pull viewers off the platform before they have watched, since watch time still matters most.
This tool is deterministic and runs entirely in your browser. It builds a proven description structure (hook, keyword-rich summary, timestamps, links, subscribe prompt, hashtags) from your inputs, instantly, with no hallucination and nothing sent to a server. Treat the output as a strong, ready-to-edit template: drop in your real timestamps and links, adjust the wording to your voice, and publish.
Free forever, no signup, no email. The generator runs entirely in your browser, so nothing you type is sent to or stored on our servers. We built it as a genuine free tool because a good description is one of the easiest ranking wins creators leave on the table. If you want your titles and descriptions scored against the videos already ranking for your keyword, you can connect your channel for a free AI audit, but that is entirely optional.
