What does SiteGround do well? The best hosting out there and best customer service! They go beyond their means sometimes to help me out with tech issues. I mean, their support will be with you step-by-step to fix your website concerns.
What does SiteGround not do well? I am a happy customer for 5 years now and has several accounts with them. Siteground is reliable. They are a bit pricey after a year but it's worth it so far, I just hope they give discounts to loyal customers like me.
What do you wish you had known about SiteGround before using? I am a happy user from the very beginning. And I highly recommend them to others!
Have you used a competitor to SiteGround? If so, how does it compare? Yes, I've used at least 2 other hosting companies prior to Siteground and their customer support is pretty bad.
