常见问题

How long should a YouTube description be?

Aim for 500-1000 words. YouTube uses the full description for SEO indexing, so longer descriptions with natural keyword usage tend to rank better. The tool optimizes length for maximum discoverability.

Do timestamps really help?

Yes! Timestamps create chapters in your video, which improve viewer experience and can appear as key moments in search results. This typically increases both watch time and click-through rate.

How many tags should I use?

YouTube allows up to 500 characters of tags. Use 15-20 relevant tags mixing broad and specific terms. The tool generates an optimized tag set based on your target keyword.

Should I include links in my description?

Yes, but keep them organized. Links to resources mentioned in the video, your social media, and related content add value. Just ensure the most important content is above the fold (first 3 lines).
