The Pros and Cons of Free vs Premium Plugins

One big choice is whether to use free plugins from the WordPress repository or invest in premium plugins. Here‘s an overview of the pros and cons of each approach:

Free Plugins

Pros

• No cost to install and use them.
• Offer basic functionality out of the box.
• Great for getting started quickly.

Cons

• Limited features compared to premium plugins.
• Less frequent updates and bug fixes.
• Lower quality support.
• Some free plugins have security risks.
• May lack documentation and tutorials.

Premium Plugins

Pros

• More features, options and settings.
• Better designed user interfaces.
• Fast and frequent updates for bugs and features.
• Direct email and chat support channels.
• Detailed documentation and tutorials.
• Low risk – established reputable companies.

Cons

• Monthly or one-time cost to purchase and use them.
• Need to renew support subscriptions annually.
• Changing platforms can be costly if locked into one vendor.

For professional sites, premium plugins provide more value, security and peace of mind. But free plugins work for simpler sites. Test both until you find the right balance for each project and client.

Installing Plugins on WordPress

Once you‘ve found the right plugins for your site, installation takes just a few clicks:

1. In your WP dashboard, go to Plugins > Add New.
2. Search for plugins or browse popular ones.
3. Click Install Now on the plugin page.
4. After installation completes, click Activate to activate it.

You can also manually upload plugin ZIP files instead of installing from the directory.

I recommend installing plugins one at a time, testing thoroughly before installing the next plugin. This helps identify any conflicts or issues quickly.

Managing Your Plugins

Properly managing plugins is just as important as choosing and installing them. Here are some best practices:

• Activate only essential plugins – Keep inactive plugins deactivated to avoid bloat.

• Configure each plugin‘s settings – Take time to optimize each plugin‘s functionality.

• Update plugins regularly – Outdated plugins risk bugs, vulnerabilities and site issues.

• Delete unused plugins – Remove plugins you no longer need to improve security and performance.

• Limit your use of plugins – Too many plugins can slow down your site, avoid going overboard.

• Test for conflicts – Make sure plugins you use function well together.

• Back up before making changes – In case you need to revert back after installing plugins.

Following these plugin management practices will keep your site running smoothly.

Securing Your Site with Plugins

Plugins introduce some security vulnerabilities to WordPress sites:

• Poorly coded plugins serve as an entryway for attacks.
• Too many plugins increase your attack surface.
• Outdated plugins harbor bugs and exploits.

That being said, security plugins also lock down sites against threats:

• Firewall plugins like Wordfence block hack attempts.
• Malware scanners detect malicious code injected into files.
• Login limiters fight brute force login attacks.
• Security hardeners like iThemes Security make sites less hackable.

My recommendation is to use only essential security plugins from trusted vendors. Avoid using too many different security plugins as they can conflict.

And make sure to keep WordPress, themes, and plugins updated at all times. Updates patch the vulnerabilities that allow sites to get hacked in the first place.

Conclusion – Start Using Plugins to Their Full Potential

Hopefully this guide provided a comprehensive overview of WordPress plugins. The key takeaways are:

• Plugins allow you to add features, automate tasks, customize design, improve performance, heighten security and connect apps.

• Most WordPress pros use a combination of free and premium plugins.

• Study ratings, downloads and reviews to choose the best plugins.
