SiteGround vs Hostinger for WordPress

SiteGround and Hostinger both sell WordPress as the default first install. They do not sell the same second year. Hostinger’s cheap WordPress story is a 48-month prepay and a $10.99 Premium renewal. SiteGround’s cheap WordPress story is a 12-month teaser and a $17.99–$29.99 renewal depending on whether you stayed on StartUp or did what their own pages steer growing sites toward: GrowBig.

If you pick the wrong one, you either overpay for support you never use or you underpay for backups and staging you needed the first time a plugin update landed on a Friday.

HostSignal compared them as a WordPress purchase, not as a brand-loyalty argument. Figures are vendor-published as of 10 September 2026. SiteGround prices below are from the WordPress hosting page (ex-VAT). Hostinger prices are from the public pricing page. Promos move.

Which SKUs are the real comparison

	Hostinger Premium	Hostinger Unlimited	SiteGround StartUp	SiteGround GrowBig
Published intro	$2.99/mo	$3.99/mo	$2.99/mo	$4.99/mo
Term for that intro	48 months ($143.52)	48 months ($191.52)	12 months prepaid	12 months prepaid
Renewal	$10.99/mo	$16.99/mo	$17.99/mo	$29.99/mo
WordPress sites	3	Unlimited (fair use)	1	Unlimited on current cards
Storage	20 GB SSD	50 GB NVMe	10 GB Google storage	50 GB
Backups	Weekly	Daily + restore tooling	Daily, geo-distributed in current copy	Daily + on-demand
Staging	On Hostinger’s broader feature list — confirm it is on this SKU before you need it	Same family; treat “free safe staging” as a product claim to verify in hPanel	Not the GrowBig exclusive	Yes — this is why GrowBig exists
PHP / cache story	LiteSpeed-class shared, you still configure a cache plugin	Same, more workers on the published grid (60 vs Premium’s 40)	Multilevel cache + Speed Optimizer plugin	“30% faster PHP” on the plan card + staging
Support shape	Chat / ticket	Chat / ticket	Chat / ticket / phone on the product’s current positioning	Same, plus the reason people pay the renewal
Money-back	30 days	30 days	30 days is the usual window — confirm at checkout	Same

StartUp vs Premium is the ad comparison. GrowBig vs Unlimited is the WordPress comparison once the site is a business.

GoGeek at $7.99/mo intro / $44.99/mo renewal (100 GB, Git, white-label, priority support) is an agency SKU. Hostinger Cloud Startup at $7.99/mo intro / $25.99/mo renewal is the “get me off the noisy neighbor” SKU. Neither is a first brochure site.

The WordPress question is operations, not the installer

Both hosts one-click WordPress. Both will migrate. Hostinger advertises free automatic migrations. SiteGround advertises a Migrator plugin and expert transfers, and says the plugin copies into an empty SiteGround site so the live origin stays up during the copy. Those are real features. They are not a promise that a 12 GB uploads directory or a custom table plugin will be instant. Use the no-downtime migration checklist either way.

The difference starts after the clone:

Updates. SiteGround’s current WordPress pages lean on managed autoupdates, in-house Speed Optimizer and Security Optimizer plugins, WP-CLI/SSH, and an “AI agent for WordPress” layer. Treat the AI agent as a convenience product, not a sysadmin. The useful part is still: core updates, a WAF story, and a support team that expects WordPress tickets.

Staging. GrowBig is the SiteGround plan that includes staging (and on-demand backups, and the faster PHP claim). If you edit a live theme because StartUp did not give you a sandbox, you did not save $12/mo. You bought a restore. Hostinger lists free staging / 1-click cloning on its broader “every plan” feature marketing. Verify the button exists on the plan you paid for before you need it. Marketing grids and SKU gates diverge.

Backups. Daily (SiteGround StartUp and up; Hostinger Unlimited and Cloud) beats weekly (Hostinger Premium) if you publish or take payments. Weekly is acceptable if you keep your own export and you rarely change the site. WooCommerce on weekly backups is how you restore into last Tuesday’s orders.

Isolation and workers. Hostinger publishes PHP-worker counts on the pricing compare grid: 40 on Premium, 60 on Unlimited, 100 on Cloud Startup. SiteGround sells visit guidance instead (~10k on StartUp in the copy we have used elsewhere on this site; GrowBig is the “growing business” tier). Worker limits are why people leave both for Kinsta or WP Engine. If you already see “resource limit reached,” stop comparing $3 intros.

Speed: vendor claims vs what you can use

SiteGround’s WordPress hosting page currently publishes a migrated-site study (1 January–30 June 2025, SiteGround Migrator, Lighthouse TTFB and Speed Index, medians). Their own footnote says they do not claim industry-leading TTFB, and that results vary by site and region. The same page still shows Hostinger and Bluehost with much slower sample TTFB than SiteGround in that dataset.

We will print that as SiteGround’s study, not as HostSignal’s lab. We did not reproduce it. Shared-host speed is a function of cache hit, image weight, region, and neighbors. A 78% “faster on SiteGround” headline is a sales artifact with a method. It can still be directionally true for a neglected shared box. It can also be a theme problem that GrowBig will not fix.

Hostinger’s performance story is LiteSpeed + CDN + a cheap plan with enough disk that you are not swapping yourself into sludge. That is enough for a brochure and a light blog. It is not a substitute for Query Monitor.

If the site is already ad-funded or running checkout, skip this pairwise and read best managed WordPress hosting, Hostinger vs SiteGround vs Kinsta, and Kinsta vs WP Engine. GrowBig’s $29.99 renewal sits next to Kinsta’s annualized ~$30. The difference is isolation, not the sticker.

Support, which is SiteGround’s product

Hostinger is efficient when the question is common and the user can follow a script. That is a valid WordPress host for a technically calm owner.

SiteGround is the host people stay with when they want a human who lives in WordPress. Phone is part of the current positioning in a way Hostinger’s cheap tiers are not. That is the thing the $17.99 and $29.99 renewals are buying when the cache is fine and the ticket is “why is checkout 8 seconds after the last plugin bundle.”

If you will never open a ticket, you are donating that premium to a brand feeling. If you open tickets at 11 p.m., Hostinger’s chat-shaped cheap tier is the risk.

Three-year cash (WordPress-shaped, before tax)

Assume published rates hold and you take the intro term:

Hostinger Premium: $143.52 for 48 months. Through month 36 you are still inside the prepay. Call the three-year hosting line ~$108.

Hostinger Unlimited: $191.52 for 48 months. Same structure; you bought daily backups.

SiteGround StartUp: ~$35.88 + $17.99 × 24 ≈ $467 through month 36, for one site and 10 GB.

SiteGround GrowBig: ~$59.88 + $29.99 × 24 ≈ $780 through month 36, for unlimited sites, 50 GB, staging, on-demand backups.

GrowBig year one is cheap. GrowBig years two and three are a managed-shared invoice. That can be rational for a lead-gen WordPress site that needs staging. It is a poor way to host a hobby recipe blog.

Hostinger Premium through the same horizon is the TCO winner by a wide margin. It is also the plan with weekly backups and no phone.

Who should pick which

Pick Hostinger Premium if the WordPress site is one to three small properties, you will keep it for years, you can follow a chat script, and you will keep your own backup. This is the default HostSignal cheap-WordPress answer. See also Bluehost vs Hostinger 2026 if the alternative in your tab is Bluehost, not SiteGround.

Pick Hostinger Unlimited if you need daily backups or more than three sites and you still refuse SiteGround’s renewal. $16.99/mo later is in StartUp’s neighborhood without SiteGround’s support story.

Pick SiteGround StartUp only for a single WordPress site that is a business surface, you want daily backups and their WP tooling in year one, and you have already accepted $17.99/mo as the real price. Do not pick it as a hobby host because the tile says $2.99.

Pick SiteGround GrowBig if you need staging, more than one site, and on-demand restores, and $29.99/mo later is acceptable. This is the “I outgrew cheap shared but I am not ready for Kinsta” SKU. It is the wrong SKU if you are already hitting PHP-worker walls or running a busy Woo catalog.

Pick neither if you need agency isolation, APM, or commerce concurrency. That is managed WordPress money.

A blunt WordPress checklist before you pay

Count sites you will actually keep, not sites you might launch in a mood.
Write down backup cadence and whether staging is on the SKU.
Write down intro, prepaid term, renewal, and money-back days.
Decline email and extra-backup add-ons you can attach next week.
If mail lives on the old cPanel, do not let MX become the outage.

SiteGround wins as a WordPress operations host. Hostinger wins as a WordPress invoice host. The installer is the same click on both. The year-two PDF is not.
