SiteGround's GrowBig plan is the strongest value signal in this category. Unlimited sites, 20GB storage, daily backups, staging, and free migrations at a price below WP Engine's single-site entry plan. An agency managing several standard client sites gets more capability per dollar with SiteGround -- and the gap widens as the site count grows.
SiteGround's GrowBig plan delivers dramatically better per-feature value for agencies managing multiple standard client sites.
SiteGround's GrowBig plan (2nd tier) includes unlimited sites, 20GB storage, daily backups, staging, and free migrations at a price below WP Engine's single-site entry plan. For agencies managing multiple standard client sites, SiteGround's per-feature value is dramatically better than WP Engine's per-site premium pricing.
WP Engine's plans are priced per site, and its entry plan covers a single install. For agencies scaling across many client sites, the per-site cost compounds quickly. WP Engine's premium positioning is defensible for high-value, high-traffic sites, but it is not the value choice for standard client portfolios.
Route-specific evidence
SiteGround's GrowBig plan includes unlimited sites, while WP Engine's entry plan covers a single install. For agencies, the multi-site difference is decisive in total cost of ownership.
SiteGround includes free migrations on its plans, removing a common onboarding cost. WP Engine charges for migrations or limits free migrations depending on the plan.
SiteGround bundles daily backups, staging, email, and CDN into its plans. WP Engine separates several of these into add-ons or higher tiers, raising effective cost.
