Here are the best hosting services for WordPress, from my point of view, and for different reasons. I often hear people having issues with their hosting so I would like to recommend you some.
WPEngine (~29$ / month)
It is simply the best. No need to install optimization, security or backup plugins, everything is done for you. It’s really good, creating a new install takes seconds, making backups and reverting changes is so easy, and if you have a question you can always talk to someone via a chat. The team is very competent and always here to help. But… it’s far from being the cheapest. I have the current website running on it and my main blog (Offbeat Japan) on it as well. More information here: WPEngine.
SiteGround (~9.95$ / month & 60% discount)
Very close to WPEngine in term of quality. It seems to me it is a bit faster than WPEngine in fact, but the security features are less obvious (though I never had any issues). The caching is included, the backup system is not as nice as WPEngine but works well. The price is much lower that WPEngine, so it is actually a better deal. I have been keeping my website Haikyo (Abandoned Places in Japan) on it for a few years and I am glad I did. More information here: SiteGround (60% off with this link).
HostGator (~3.95$ / month)
The cheapest. Unlimited everything. That is basically what
