SiteGround's pricing model is significantly more accessible for agencies. Free migrations, included email hosting, and no per-site premium billing make the economics of managing a standard client portfolio much cleaner compared to Kinsta's plan structure.
SiteGround's GrowBig plan covers most agency use cases at a fraction of Kinsta's entry Business plan — with free migrations and included email hosting.
A direct pricing comparison reveals a significant value gap. SiteGround's GrowBig plan covers the majority of standard agency client site requirements — multiple sites, SuperCacher, staging, daily backups, CDN — at a price point well below Kinsta's entry Business plan. SiteGround also includes free professional migrations, email hosting (no additional G Suite or Microsoft 365 cost), and a CDN in the base plan price. Kinsta's per-site billing model and Google Cloud infrastructure premium make it a difficult economic case for agencies managing five to twenty standard client sites.
Kinsta's pricing reflects genuine Google Cloud C2 infrastructure investment. For performance-critical sites where the infrastructure cost is justified by client requirements, Kinsta's plan value is clearer. The premium is harder to justify for standard brochure sites and lower-traffic client work.
Route-specific evidence
SiteGround includes free professional migrations on GrowBig and GoGeek plans. Moving a client portfolio from another host involves no per-migration fee — a meaningful budget line when moving five or more sites.
SiteGround includes email hosting in its managed WordPress plans. Kinsta does not include email hosting — agencies must budget separately for Google Workspace or another email provider for every client domain.
Kinsta's billing is per-site and per-visit-tier. SiteGround's GrowBig plan allows multiple sites with a shared resource model that better suits agencies managing a range of standard-traffic client sites.
