Theme choice impacts website speed. WordPress is an open market, thus developers take varied approaches to theme creation. Good-looking themes are often unoptimized and slow to load.

1. Use Fast and Lightweight Theme/Framework

WordPress is popular because plugins bring additional functionalities. If you need to optimize photos, find a plugin. Poor code results from plugins that don't follow development principles. To maximize efficiency, developers must optimize plugins like themes.

Any website—blog or business—needs images. Unoptimized photos might slow down your site, so optimize them. Image optimization has two methods. You can optimize images manually or with a plugin.
