SiteGround vs WP Engine: Best WordPress Hosting for Agencies?
Let’s look at SiteGround vs WP Engine because we know that choosing a WordPress host is more than infrastructure – it’s about workflow efficiency, client satisfaction, and predictable scaling.
Agency owners and developers managing multiple clients need robust performance, streamlined workflows, agency-grade support, and transparent pricing.
When researching “SiteGround vs WP Engine” or “SiteGround vs WP Engine performance”, you’re not comparing generalist hosts – you’re choosing a platform that impacts your bottom line.
In this guide, we’ll:
- Compare SiteGround and WP Engine across key criteria
- Highlight where both can fall short for agencies
- Introduce a third option – Pressillion
“After moving to pressillion from WPengine. PHP worker limitation is completely mitigated. The website can now easily handle 300 orders per minute, where WPengine maxed out at about 7.”
Performance: SiteGround vs WP Engine Speed & Reliability
SiteGround is built on Google Cloud with SSD storage and proprietary SuperCacher tech. It performs well for small-to-midsize WordPress sites but can suffer under WooCommerce or dynamic loads.
WP Engine delivers excellent performance thanks to its EverCache system and Google Cloud backbone. However, performance can be throttled at scale unless you upgrade to more expensive plans with higher PHP worker limits.
Pressillion is optimized for speed and scalability. With containerized hosting, NGINX microcaching, Redis object caching, and FastCGI, it delivers faster load times and more consistent performance – especially under traffic spikes.
Developer Workflows: Built for Teams
SiteGround offers Git integration and staging, but only on higher-tier plans. SSH and WP-CLI access are limited, and workflows often rely on GUI-based management via Site Tools.
WP Engine provides Git, SSH, WP-CLI, and staging across all managed plans. It’s built for modern developer workflows, though scaling development teams increases your monthly cost.
Pressillion includes WP-CLI, SSH, and staging workflows by default. It’s built for teams who need power and flexibility without having to upgrade just to get basic tools.
WooCommerce Handling
SiteGround supports WooCommerce, but caching can interfere with cart and checkout pages unless manually excluded. It lacks built-in transactional email handling.
WP Engine offers WooCommerce-optimized plans with cache exclusions and plugin monitoring. However, performance still depends on plan tiers, and higher PHP worker limits come at a cost.
Pressillion is WooCommerce-ready out of the box. It includes cache exclusions for key e-commerce pages, Redis for object caching, and FastCGI microcaching – all pre-configured.
Pricing & Cost Transparency
SiteGround starts at low entry prices but renews at much higher rates. Essential features like staging, backups, and enhanced caching require higher plans.
WP Engine starts around £30/month and increases based on PHP workers, site count, or multisite support. Costs are predictable but scale quickly.
Pressillion uses a flat hosting pricing model – all features included. You get transparent, predictable costs without surprise fees or upsells.
Agency Scaling and Multi-Site Management
SiteGround isn’t built for agencies managing large portfolios. No central dashboard, limited multisite support, and individual plan scaling makes growth clunky.
WP Engine supports multiple sites and multisite networks, but scaling past 25–30 clients requires considerable plan upgrades.
Pressillion is designed to handle multiple high-performance sites per account. it supports multisite, offers flexible infrastructure, and maintains consistent performance regardless of scale.
Support Experience
SiteGround provides 24/7 support via live chat and ticketing. Response times are fast, but support is tiered, and deeper technical help is limited to higher plans.
WP Engine offers strong WordPress-focused support. Response quality is solid, but WooCommerce and complex issues may require escalations or plan upgrades.
Pressillion connects you directly to engineers via LiveChat and email. There are no tiers, queues, or scripts – just expert WordPress support designed for agencies managing real workloads.
Migration & Onboarding
SiteGround to WP Engine migrations can be done via plugins or manually – WooCommerce stores and large multisites require technical assistance.
WP Engine to SiteGround migrations typically involve backup exports, reconfiguration, and DNS changes – requiring hands-on effort.
Pressillion offers a white glove migration experience. The migration team handles every step: DNS, SSL, plugin auditing, and performance tuning. Zero-downtime is standard. No need for DIY or third-party tools.
