Even though there are more than 55,000 plugins available in the official directory, you surely don't need all of them on your WordPress site at the same time. There is a small set that we might call the must-have pack. My list of must-have plugins can be different from the next guy's, so treat the following information more as guidance rather than as a written-in-stone necessity. That being said, if I am honest here, and despite the fact that some of my blogs feature more than 25 plugins all working at the same time, the essential must-have list consists of only seven plugins. All these plugins handle a specific task geared toward making a WordPress site better and more functional.
