Four YouTube keyword research tools that actually drive views

Executive overview

Most YouTube keyword tools show search volume and competition scores that are unreliable. Four tools — used in combination — give you enough signal to pick topics with genuine search demand.

The real edge comes from combining tools: use one for rank tracking, one for trend spotting, one for keyword volume, and one to capture Google traffic.

TubeBuddy

• Ignore the search volume numbers — they're wildly inflated (e.g., claims 7.1M monthly searches for "SEO"; actual impressions from a #1 ranking were under 69K)
• Competition scores are opaque; methodology isn't published
• Rank Tracker is useful: add keywords, schedule weekly/monthly reports, track your rankings and competitors'
• Most Used Tags widget shows tags competing videos apply — helps YouTube categorise your content for suggested views

vidIQ

• Global search volume estimates are closer to reality than TubeBuddy's, but still inflated
• Competition score is based on engagement, subscriber counts, and social shares — misses ranking factors like topical relevance and session watch time
• Trending videos by channel is the standout feature: shows any channel's top videos by view velocity (views per hour)
• Filter for videos published months ago that are still generating consistent views — these are ranking in search or suggested, signalling lasting demand
