Recommended WordPress Plugins and Places to Buy Plugins
One important caveat about plugins before we go into the recommendations: only use the plugins that you really need for your site. Many site owners go crazy adding every plugin they can find, not realizing that each new plugin represents more potential maintenance, and sometimes even a security risk.
In terms of free plugins, you can find some great ones, no doubt; but just be sure that the plugin developer is actively updating the plugin. If they’re not making any money, there’s a good chance they’ll abandon the plugin at some point, leaving a security hole in your website.
That being said, the following specific plugin recommendations, for the time being, are totally safe and will benefit many sites. Most, but not all, of them are free.
