The term plugin (also called an extension or add-on) comes from computing. It refers to a non-standalone program that works with another program to extend or enhance its original features.
What are plugins?
In practice, plugins are add-on components, pieces of code written by third-party developers.
As mentioned in the introduction, they serve one key purpose: extending the functions of the browser or program they’re connected to.
They come in every imaginable type: to optimize SEO, add contact forms, create photo galleries, improve file management… even to turn any website into a full-fledged online store. And many, many more.
The important thing is to choose plugins that fit your needs.
Tips for choosing plugins
Despite the wide range of plugins available, you shouldn’t go overboard, even with free ones.
Installing many extensions at once can cause problems, such as slowing down the site or causing all sorts of malfunctions.
But there’s no need to worry. Just pay attention and take a few extra precautions.
Here are some rules to follow before installing:
- Check the information, technical specs and reviews of the plugin you’ve chosen.
- Avoid installing extensions that haven’t been updated in a long time, because they could pose security risks.
- Install only official plugins or ones downloaded from trusted sites.
How WordPress plugins work
Everyone knows WordPress, the world’s most widely used CMS for building blogs and websites. But this platform has an obvious “flaw”: without its plugins, it would be quite limited.
That’s why it offers more than 50,000 free plugins, plus thousands more in freemium or paid versions.
Among the best known currently available, it’s worth mentioning:
- W3 Total Cache, designed to speed up the loading of your web pages;
- Easy Social Share Buttons is ideal if you want to add social sharing buttons;
- All In One SEO Pack, very similar to Yoast SEO, helps you create search engine optimized content;
- WPTouch to create mobile or responsive versions of your website.
