Most problematic WordPress websites have one thing in common:
Loads of ACTIVE plugins.
Installing a plugin should not be an easy decision. Poorly written plugins or those that might not work together with other features on your site can lead to:
- Security Issues: you’re giving a third party access to your website.
- Bugs: If you’re not working with an experienced developer, some of the plugins you use might not be compatible with your theme or with each other.
- Speed: If the plugin you’re using takes time to load, then you’re compromising speed on your site.
If you attend a blogging course and you’re advised to install a bunch of plugins, be cautious and take your time before you install and activate.
Consult with a developer for plugins that sell security, so you understand how exactly the software is securing your website.
I’m not saying you should stay away from plugins all together, but assess the quality of the plugin and if there are other ways to achieve the feature you want, without compromising your website’s security and functionality.
Questions to ask if you’re stuck and unsure about which plugins to use. Is it necessary? Is this for style or to improve user experience on your site? Do I understand how this plugin works? Is there another way to get the function or effect I want without installing a plugin?
