WordPress powers over 43% of all websites on the internet. That makes it the most popular CMS in the world. But popularity doesn’t always mean it’s the best choice. Let’s take a detailed look at when WordPress makes sense and when a custom website is better, including hidden costs, security, and real-world experience.
When to Choose WordPress
WordPress is the right choice in several specific situations:
You need a blog or news section. WordPress was built as a blogging platform and content management is its strength. The Gutenberg editor lets you create articles with blocks, images, and videos without any coding knowledge. For businesses that publish regularly (e.g., weekly articles), it’s an ideal solution.
You want to manage content yourself. The admin panel is intuitive and easy to learn. Most clients can add a new article or edit text within 15 minutes of their first login.
You have a limited budget. Themes and plugins enable a quick start at lower cost. A basic WordPress site can be built from €600, while a custom website typically starts from €1,200.
You need an online store. WooCommerce is a proven solution for smaller shops. With plugins like Stripe and PayPal, you can start selling within days.
You need a quickly launched project. Thanks to thousands of ready-made templates, you can have a functional website within a week. For a custom website, expect 3–6 weeks.
When to Choose a Custom Website
A custom website is an investment that pays off in these cases:
Speed matters to you. A custom website has no unnecessary code. The average WordPress site loads 2–3× more data than an optimized custom website. In practice, a WordPress page weighs 2–4 MB while a custom site fits under 500 KB. This has a direct impact on conversions, and every extra second reduces conversion rate by up to 7%.
You need a unique design. Templates limit creativity. A custom website looks exactly the way you want. No compromises, no “the template can’t do this.” Every pixel is under your control.
Security is a concern. WordPress is a frequent target of attacks precisely because of its popularity. According to Sucuri, WordPress accounts for 95.5% of hacked CMS websites. Every plugin is a potential security vulnerability. A custom site without a CMS has no database, no login form, and a minimal attack surface.
You don’t want to deal with updates. WordPress requires regular updates to its core, theme, and plugins. Neglecting updates leads to security risks and incompatibilities. A custom site in pure HTML/CSS/JS is practically maintenance-free and works for years without intervention.
SEO is your priority. A custom website gives you full control over structured data, semantic HTML, and technical SEO. No plugin conflicts, no unnecessary scripts slowing down page load.

Hidden WordPress Costs
The main appeal of WordPress is its low initial price. But beware: total cost of ownership is often higher than it seems:
Premium theme: a quality theme costs €60–€120/year (licenses renew annually)
Plugins: backup plugin, SEO plugin, security plugin, cache plugin. Each PRO version €20–€80/year. For an average website you need 5–10 plugins.
Hosting: WordPress requires PHP and MySQL, meaning more expensive hosting. Shared hosting from €40/year, but for decent performance you need VPS from €120/year.
Updates and maintenance: regular WordPress, theme, and plugin updates take 2–4 hours monthly. If you can’t handle it yourself, maintenance costs €20–€60/month.
Security incidents: fixing a hacked WordPress site typically costs €200–€800. Not counting losses from downtime.
Total 3-Year Cost Comparison
Let’s look at a realistic comparison of total costs for a business presentation website (5–10 pages):
Custom website: initial build €1,800 + hosting €20/year + maintenance €0 = approx. €1,860 over 3 years
A custom website comes out about 30% cheaper when looking at the three-year period. And that doesn’t count higher conversions thanks to faster loading.
From My Experience
In 3 years of building websites, I’ve worked with both approaches. One client came with a WordPress site that loaded in 6 seconds and had 23 active plugins. After converting to a custom website, load time dropped to 0.8 seconds and bounce rate decreased by 35%.
Another client needed an e-shop with 500+ products and regularly added new items. For them, WordPress with WooCommerce was the clear choice, since managing a product catalog manually in HTML would have been impractical.
The rule I use: if a client needs to change content more often than once a month, choosing a CMS makes sense. If content stays more or less the same, a custom website is more efficient.
How to Decide
Ask yourself three questions:
How often will I change content? Weekly or more? WordPress. Monthly or less? Custom website.
How many pages will the site have? Dozens to hundreds? WordPress. Under 20? Custom website.
What’s more important, speed of deployment or long-term quality? Need a site in a week? WordPress. Can wait a month and want a better result? Custom website.
Migrating from WordPress to Custom
Switching from WordPress to a custom website is simpler than it seems. The typical process looks like this:
Analyzing the existing site: mapping all pages, forms, and features the website uses. Most business presentations have 5–15 pages and a contact form.
Content export: texts and images are exported from the WordPress database. Content stays the same, only the technical implementation changes.
New design and code: the website is built from scratch in pure HTML/CSS/JS. This phase typically takes 2–4 weeks.
URL redirects: 301 redirects are set up from old WordPress URLs to new addresses to preserve SEO value and prevent users from landing on error pages.
Testing and launch: checking all pages, forms, speed, and SEO. Migration is typically completed within a month.
Clients who migrated from WordPress often cite freedom from update stress and security threats as the biggest benefit.
WordPress Security in Detail
Security deserves a closer look. The biggest WordPress risks are:
Outdated plugins: the average WordPress site uses 20–30 plugins. Each can contain vulnerabilities. In 2024, over 4,000 security flaws were discovered in WordPress plugins.
Brute-force attacks: the wp-login.php page is publicly accessible. Bots attack it automatically, trying thousands of password combinations daily.
SQL injection and XSS: a poorly written plugin can allow attackers to access the database or inject malicious code into the website.
Defacement: attackers change website content, damaging the company’s credibility and potentially leading to Google penalties.
A custom website without a database and admin panel practically eliminates these risks. A static HTML site cannot be hacked the same way as a dynamic CMS.
Impact on SEO and Google Rankings
Since 2021, Google has used Core Web Vitals as a ranking factor. Key metrics include:
LCP (Largest Contentful Paint) measures how quickly the main content appears. Target: under 2.5 seconds. WordPress sites often exceed 4 seconds, while custom sites typically load under 1 second.
INP (Interaction to Next Paint) measures how quickly the site responds to clicks. Loading dozens of plugin JavaScripts significantly slows response time.
CLS (Cumulative Layout Shift) measures the visual stability of the page. WordPress themes with external fonts and ads often have high CLS.
Better Core Web Vitals means higher search positions. For a business that depends on organic traffic, this can mean a difference of thousands of euros monthly.
Comparison in Practice
For a business presentation website with 5–10 pages, a custom website is often the better choice. It will be faster, more secure, and won’t tie you to a plugin ecosystem. For content-heavy websites with dozens of pages, WordPress can be more efficient.
It always depends on the specific project. There is no universally correct answer, only the right answer for your situation.
