The bottom line
GreenGeeks' angle is sustainability: it buys renewable energy credits equal to three times its usage. Plans include daily backups and cPanel; renewals are steep (Lite goes from $2.95 to $13.95).
SiteGround is the premium shared host: daily backups, staging and excellent WordPress tooling, with a cheap first year that only needs a 12-month prepay. Renewals are the steepest we track: StartUp goes from $2.99 to $17.99 a month.
Frequently asked questions
Is GreenGeeks cheaper than SiteGround?
Over three years, GreenGeeks costs less on the cheapest comparable plans: about $370 versus $468, counting the intro price for its required term and then the renewal price. Month one is misleading: compare the 3-year totals.
Which has the better money-back guarantee?
GreenGeeks: 30 days. SiteGround: 30 days. Domain fees are usually not refundable.
Can I move from GreenGeeks to SiteGround later?
Yes. Moving a site means copying its files and database, then pointing your domain at the new host. SiteGround advertises free migration: Free WordPress migrator plugin. See our guide to switching hosts.
