SiteGround is the absolute best hosting company in the world. I have used nearly 4 other hosting companies, but once I found SiteGround the search was over. The hosting is fast and reasonably priced and the support is AMAZING. Literally, the support has saved me so much time and money over the months.
The support has helped me with errors I get on my site not even related to hosting. They are so knowledgeable, friendly, and even funny at times. Most hosting companies have terrible support from what I have found. SiteGround is top-notch!
Also, I should mention that if you use WordPress SiteGround offers an amazing site optimizer plugin and a security plugin. These are exclusive to SiteGround and are amazing!
