Is WordPress still the best platform to start a blog in 2025?
Yes, WordPress continues to be the most popular and beginner-friendly blogging platform in 2025. It offers thousands of free themes and plugins, complete control over design, and full ownership of your content — something most free blogging platforms don’t provide. Whether you’re writing tutorials, travel stories, or reviews, WordPress gives you the flexibility to grow from a simple personal blog into a professional website as your audience increases.
Why should I use Hostinger to start my WordPress blog?
Hostinger is ideal for beginners because it combines performance, affordability, and simplicity. It offers fast LiteSpeed servers, one-click WordPress installation, automatic updates, and a free domain name — all at a fraction of the price of most other hosts. Its user-friendly dashboard makes managing your blog effortless, even if you’ve never built a website before, and their 24×7 support ensures you’re never stuck.
How much does it cost to start a blog on WordPress with Hostinger?
You can start a fully functional WordPress blog for less than the cost of a coffee each month. Hostinger’s WordPress Starter Plan typically starts under $3/month and includes free domain registration, SSL certificate, and email hosting. That means your total first-year setup often costs less than $40–50, which is an incredible deal for a fast, secure, and professional-looking blog.
Do I need to know coding to create a blog on WordPress?
No, coding knowledge isn’t required to start or manage a WordPress blog. The platform is designed with non-technical users in mind. You can choose a theme, customize layouts through a drag-and-drop editor, and publish posts without touching a single line of code. If you ever want to enhance functionality, WordPress plugins handle almost every feature — from SEO to forms — with a few clicks.
How long does it take to set up a WordPress blog on Hostinger?
Most beginners can set up a complete WordPress blog in under 30 minutes using Hostinger’s guided setup. After signing up, you simply select a domain name, install WordPress with one click, and choose a theme. Once your site is live, you can immediately start publishing posts and customizing the design at your own pace.
Can I make money from my WordPress blog later?

You can earn through Google AdSense, affiliate marketing, sponsored content, digital products, or even online courses. Starting with Hostinger gives you the flexibility to scale easily as your audience and income grow.
What are the common mistakes beginners make when starting a blog?
New bloggers often spend too much time on design and too little on writing consistent, valuable content. Others use free subdomains instead of registering their own, which limits branding potential. Choosing a reliable host like Hostinger from the start ensures your site loads fast, stays secure, and looks professional, helping you avoid many beginner pitfalls.
