Why most SEO hires disappoint
Most SEO engagements underperform for one of three reasons: the senior who won the pitch hands the work to juniors, the provider optimises for vanity metrics instead of revenue, or they chase volume (mass content, cheap links) that Google later punishes. None of these are visible in a polished sales deck.
The fix is to buy outcomes and seniority, not promises and headcount. The rest of this guide is how to tell them apart before money changes hands.
