Speed up WordPress Website | Decrease Loading Time | Increase Website Performance

All of these methods can be and should be used together !
————O————

 #1.  Check  WordPress performance with the following tools

              •  Web performance tools at Google
              •  GTmetrix website performance test
              •   Pingdom Website speed test

 #2.  Compress Images

              •   Compress images to web quality
              •   You can use following plugins to compress all the images and future uploads
=   EWWW Image Optimizer
                   =   WP-Smush – Image Optimization

 #3.  Utilize Caching

              •   A Cache is something that stores data on the viewer’s machine, so future requests for that data can be served faster.
              •   On WordPress, a caching plugin with store your posts and pages as static files so that your server doesn’t need to think every time it serves a page

              •   You can use the plugin GZip
              •   Alternatively, most caching plugins such as W3 Total Cache also offer this

                      /%category%/%postname&/
                      “http;//dev.bdhostit.com/contact”
              •   Use a numerical field such as
                      /%year%/%monthnum%/%postname%/
                      “http://dev.bdhostit.com/2018/3/earn-money”

 #6.  Use a content delivery network (CDN)

              •   A CDN uses several servers around the world to better serve data to your viewer’s dependant on their location
