WordPress is the world's most popular open source
content management system (CMS), but its standard set of features
leave a bit to be desired for organizations using WordPress to
power their blog or entire website. However, thanks to a few free
WordPress plugins, you can help boost your search engine
friendliness, do a better job with web analytics, create better
copy, and much more.
Before you start installing any plugins, it's a good idea to do
a full backup of your WordPress directory and database. Ideally,
you should have a test deployment of WordPress alongside your
production site to test plugins and other changes before you make
them live. In seven years of using WordPress, I've never had a
problem installing plugins – but there's always a first time.
'Better safe than sorry,' may be a cliché, but it became a
cliché because it's true.
