use Capsai to create perfectly time‑synced, keyword‑rich subtitles in multiple languages. upload your video or paste its URL, generate subtitles, then edit to include your target search terms naturally
link: https://capsai.co/ - research and select target keywords
use tools like Google Keyword Planner or Capsai’s keyword intelligence to find high‑value search phrases related to your topic - for example “ai subtitle generator” or “how to add hinglish captions” - integrate keywords into your transcript
edit your generated subtitles so that your primary keyword appears at least once every 30–60 seconds of spoken content, without sounding forced or repetitive - optimize your subtitle file metadata
when exporting SRT or VTT, name the file with your main keyword - for examplehow-to-add-captions.ai-subtitles.srt -and reference it in your HTML or platform upload settings - mirror on‑screen text with captions
if you display key phrases as text overlays (titles, call‑outs), make sure the same words are present in your subtitle file so search engines can index them - include synonyms and long‑tail variants
to capture related searches, sprinkle in natural variations of your main keyword - such as “video captions seo,” “youtube subtitle optimization” - across different parts of the transcript - add speaker labels and descriptive cues
use labels like SPEAKER: or cues such as [background music] to improve context and keyword density, which some platforms index for relevance - structure your captions for readability
keep each line under 40 characters, use proper punctuation, and split at sentence breaks so indexing algorithms parse your content accurately - upload subtitles as separate tracks when possible
on YouTube Studio or Vimeo, add your SRT/VTT under Subtitles → Add Language rather than hard‑coding, enabling search engines and viewers to toggle captions - monitor search performance and iterate
use analytics to track which subtitle keywords drive impressions and watch time. refine your transcript wording every quarter, adding new trending terms to stay ahead of search trends.
