There are over 55,000 plugins in the WordPress directory. That’s enough to make anyone a little nauseous. A quick search for optimization plugins in WordPress’s official plugin marketplace turns up over 130 pages of results. At Site Assembly, we’ve used all the best plugins on our Managed Sites. As a result, we’re here to recommend the top WordPress optimization plugins every site needs to stay fast and secure.

Before we begin, always make sure you’re making site changes on a STAGING website. If you’re not familiar with STAGING environments or don’t have a STAGING website set up, I recommend setting one up before continuing. If you are unable to set up a STAGING site, at the very least you should back-up your site in case anything goes wrong.
