YouTube Ads for service-based consulting can work, but it's a different beast. Most people forget that YouTube's intent is nothing like search - no one's actively hunting for a solution there, so your ad has to grab them in the first three seconds or you're done. For a £30-50 consult, cold broad audiences are a gamble. Lookalikes of past clients or people who've already engaged with your educational content are your best bet.
Definitely test skippable in-stream ads with a direct CTA to book the call inside the ad itself. Since your initial offer is low-ticket, you can optimise for clicks or conversions rather than vanity views. Start with £20 a day, try three different hooks, and ditch anything that doesn't hit at least 15% view-through rate after three days.
The backend is where most people lose it though. You're selling a £2500 service - if the follow-up sequence feels transactional, you'll get bookings but no conversions. Spend the first ten minutes diagnosing their actual email marketing stack pain points before even hinting at an upsell.
I randomly joined the waitlist for something called Hoox recently - it's an autonomous AI CMO that apparently posts daily SEO articles, TikTok and Instagram content, YouTube videos for AI search, and even monitors forums like this 24/7. There's also a Telegram agent that does real-world tasks. No access yet, but the top-of-funnel compounding angle feels relevant to what you're describing.
What's your current client acquisition looking like? Any organic traction from content or referrals, or is this your first real push into paid ads?
