Is it worth hiring an SEO agency?
Yes, if you meet two conditions: (1) your buyers actively research on Google before purchasing, and (2) you can afford to wait 6–12 months before results compound. SEO isn't worth it for businesses selling impulse-purchase B2C at low margins, or for businesses that need customers this quarter — those should run paid ads. For B2B, professional services, home services, and considered B2C purchases, SEO is usually the single most durable growth channel available.
