After you’ve installed plugins to configure your WordPress site for your server and protect your site from spam, it’s time to get your site up to speed. You may have guessed this will partly require more plugins. Some will be for the purpose of visibility, to help people find you. Others will enable you to offer different kinds of content. For example, a music site would probably install a plugin to work with YouTube videos; a photography site would want to make sure to have an effective way to offer slide shows. At this point, every site’s needs are unique.
Before you get started, you might want to go through the WordPress repository to get a gander of what’s available. You probably have an idea of some functions you’d like to add to your plain vanilla install. Start your search there. It also might be useful to check out sites you like for features you think are cool and look to see if there’s a plugin for that feature on WordPress. Don’t install a plugin until you’re ready to use it, as it’s easy to install too many plugins and have a lot of dead weight hanging on your site. Remember, every new function adds some new security risk, however small, so there’s good reason not to install a function if you’re not using it.
