The most popular WordPress plugins - such as Yoast SEO for search engine optimization, Contact Form 7 for forms, WP Rocket for caching, and Elementor for page building - are everyday tools for most administrators. Free versions of these plugins are sufficient for many to start with, but sometimes a quality paid plugin can save you time and frustration.
However, when selecting plugins, you should be careful. Too many installed plugins slow down your site and can also cause compatibility or security issues. The most important thing is to identify which plugins are genuinely necessary for your site and focus on those.
Essential WordPress Plugins for All Websites
Effective operation of a WordPress site requires the right tools and plugins. Here are the most important plugins that every WordPress user should install to make their site visible in search engines and to function quickly, securely, and user-friendly.
Visibility through Search Engine Optimization
Search engine optimization is the cornerstone of your website's visibility. Yoast SEO and Rank Math are the best-known SEO plugins that help optimize your content for search engines.
These plugins provide you with features such as:
-
Keyword analysis and content assessment tools
-
Meta-data management for articles and pages
-
XML sitemaps for search engines
-
Optimization for social media sharing
Yoast SEO is easy to master, especially for beginners. Rank Math offers more features even in the free version. Both clearly show how to improve content for search engine visibility. However, install only one of these SEO plugins - not both!
Usually the free version will get you far, but the paid version can save you valuable time.
Additionally, you should install some visitor tracking on your site, e.g. Google Analytics plugin. It tells you important information about where visitors come from and what they do on your site.
Hostaan's WordPress hosting packages automatically install the Rank Math SEO plugin, so your WP site is immediately ready for optimization.
Performance is Key
Your website's loading speed matters a lot: both in the eyes of visitors and search engines. WP Optimize is an excellent plugin that, in addition to caching, takes care of optimizing your images.
If you want to try another alternative, consider these:
-
W3 Total Cache – versatile caching solution
-
WP Rocket is a plugin that speeds up your site automatically.
-
But remember again: install only one
With these plugins your site:
-
Loads pages faster from cache
-
Automatically reduces images and other files to download
-
Delays loading of heavy elements until they are needed (lazy load)
Hostaan web hosting offers excellent performance and reliable service for your WordPress site thanks to fast SSD drives and 24/7 monitoring. With caching plugins, you get even more out of your site's speed. Hostaan's web hosting packages automatically install the user-friendly WP Optimize.
Security Above All
Online security is now more important than ever. Sucuri and Wordfence are the two most common security plugins for WordPress.
Their most important features:
-
Login attempt limitations
-
Malware scanning and removal
-
Security update management
-
Firewall to prevent attacks
UpdraftPlus or another backup plugin is also almost mandatory. It allows you to automatically save your site to cloud services like Google Drive or Dropbox. You never know when a backup will actually be needed.
Hostaan's web hosting packages take care of your site's security with an application firewall and WPS Hide Login plugin. In addition, in our SmartWP hosting packages, security updates are also handled with functional testing and certainty.
Reservations, Contacts and E-commerce
Customer service is the foundation of all business. Contact Form 7 is a popular contact form plugin that can be easily customized to your needs.
Contact Form 7 is automatically installed in all our WP hosting packages.
E-commerce and reservations are handled with these:
-
WooCommerce – the market's most popular e-commerce solution
-
Bookly, Amelia, Bookingpress, Booking Calendar – appointment scheduling system for WordPress
These plugins integrate seamlessly with your WordPress site and make communication with customers easy. Mobile compatibility is considered in all of these – and that's absolutely necessary nowadays.
WordPress Plugin for All Needs
The versatility of WordPress is particularly evident when you need something a bit out of the ordinary. Whether it's an online store or content production challenges, there are almost always ready-made tools for special situations... and if something doesn't exist yet, you'll surely find a suitable WordPress developer for your project.
E-commerce Plugins
WooCommerce is the king of online stores in WordPress. This easy-to-use plugin turns your regular WordPress site into a functioning online store in just a few minutes.
The best part is that WooCommerce is completely free!
WooCommerce also has a huge number of extensions:
-
Payment methods: Klarna, PayPal, Stripe, Paytrail, Visma Pay, card payments
-
Shipping integrations: Posti, Matkahuolto, DB Schenker
Complete customization is perhaps WooCommerce's biggest advantage, but it also brings challenges. You can choose a suitable theme for your store and easily customize it according to your company's brand. But - if problems arise, you cannot call the online store application's customer support.
All our WooCommerce hosting packages automatically install the most important WooCommerce plugins, such as Posti Shipping, Visma Pay and Complianz (GDPR cookie banner)
Content Production Plugins
Elementor is a content creator's dream tool. With this visual page builder, you can create even complex pages without coding skills. Another alternative is Divi, which also offers an easy way to get started.
Divi's "drag and drop" functionality makes content editing really easy. You don't need to be a nerd to create impressive pages.
Do you publish a lot? Editorial Calendar helps visualize publishing schedules. You can see a whole month's publications at a glance and easily move articles to different days.
