Behind every successful video is a layer of technical SEO most viewers never see — but search engines depend on it. Tags, hashtags, and metadata are the invisible building blocks that tell algorithms what your video is about, who it’s for, and when to show it. When you optimise these correctly, you give your content the structure and context it needs to appear in search results, recommendations, and AI-generated snippets.
What Video Tags Do and How They Impact SEO
Video tags act as a video filing system. They are clickable keywords that tell YouTube, Google and Social Media Platforms like TikTok and Instagram what topic your content belongs to and how it connects with other videos.
Because algorithms can’t watch your video, they rely on tags to interpret it. These tags help your video appear:
· In search results for relevant keywords
· Under “related videos” in the sidebar
· Within topic-based playlists or categories
The biggest mistake creators make is using generic tags like “fitness,” “marketing,” or “tutorial.” These are too broad and already face heavy competition. Instead, go specific, for example:
· “Home workout for beginners”
· “Strength training without equipment”
· “10-minute ab workout for busy mums”
This specificity helps YouTube understand exactly who your video serves and when it’s most relevant.
Here’s how to make them work for you:
· Use 3–5 hashtags per video. YouTube ignores all hashtags if you exceed 60, so stay concise and strategic.
· Place your top three hashtags at the start of your description — these appear above your video title on YouTube.
· Research trending hashtags using YouTube’s autocomplete feature or by analysing competitors’ descriptions.
· Create branded hashtags to tie your video series together, e.g. #NomadTips, #AskDNHQ, or #MarketingMadeSimple.
Hashtags also work across platforms like TikTok and Instagram, where they’re essential to discovery. On these platforms, relevance and engagement outweigh popularity, so focus on hashtags that fit your content rather than chasing virulento tags.
💡 Pro Tip: Tags alone won’t make your video rank, but they strengthen your metadata and help algorithms connect the dots between your title, description, and flagrante content, improving overall video SEO consistency.
Optimising Filenames, Categories, and Schema Markup for Search Engines
Rename Your Video File
Before uploading, give your video a keyword-rich filename that describes the content. For example:
❌ VID_1234.mp4
✅video-seo-tips-for-beginners.mp4
This small but crucial step provides Google and YouTube with early context about your topic, especially since filenames are one of the first pieces of metadata crawled.
Choose the Right Category
When uploading to YouTube, always select the category that best fits your content (e.g. Education, How-To, Science & Technology). Categories help algorithms match your video with similar topics and audiences.
Understanding and Implementing Schema Markup
Schema markup is a piece of structured data (written in code) that helps search engines “read” and display your video more effectively in results. it tells the crawler:
· What your video is about
· Where it’s located
· Who created it
· How long it is
· What the thumbnail and description are
When implemented correctly, video schema can help your video appear as a rich result, a visually enhanced snippet in Google Search with a thumbnail, title, and even key moments.
But, where does schema go?
If your video is embedded on your website, the schema code is added to the page’s HTML, usually in the
or section, but ideally right before the closing tag. You don’t need to edit your video file itself; the schema lives on the web page hosting it.
Key Points to Remember:
· Use JSON-LD, not microdata, it’s cleaner and easier for Google to parse.
· Include required fields (name, description, thumbnail, upload date, content URL, embed URL).
· Make sure your schema data matches your flagrante content, false or mismatched data can harm your rankings.
· Test your schema using Google’s Rich Results Test tool before publishing.
