Creating a WordPress website is simple, but even experienced developers make mistakes that end up costing a lot: lost traffic, slow loading, Google penalties. I’m a WordPress developer with 5+ years of experience — I’ve seen hundreds of such sites and fixed 90 % of them. In this article — the top-10 mistakes when creating a WordPress website in 2025 and how to avoid them. If you don’t want to risk it — message @gurtop, I’ll build a site without mistakes for $250+.

Why WordPress Website Creation Mistakes Are Still Relevant in 2025

WordPress powers 43 % of all websites worldwide, but 70 % of beginners make basic blunders. Result: the site doesn’t index, conversion drops by 50 %, hosting crashes under load. My clients see +30–100 % traffic growth after fixes.

TOP-10 WordPress Website Creation Mistakes and How to Avoid Them

1. Choosing a Heavy Theme or Plugins
   Mistake: Installing 20+ plugins (Elementor Pro + 10 widgets) + a premium theme like Avada. The site “lags” to 5–7 s load time.
   How to Avoid: Use Hello Elementor (lightweight, free) + Elementor Free. Add only 5–7 plugins (Rank Math, Contact Form 7, WP Rocket). Test speed in PageSpeed Insights — aim for 95+.
2. Ignoring Mobile Responsiveness
   Mistake: Design only for desktop — on mobile, text “crawls,” buttons aren’t clickable. 60 % of mobile traffic is lost.
   How to Avoid: In Elementor, switch to Mobile/Tablet while editing. Use responsive breakpoints (768px, 480px). Test in Chrome DevTools.
3. No Basic SEO
   Mistake: No title/description, alt texts, sitemap. The site doesn’t index, traffic is zero.
   How to Avoid: Install Rank Math — it generates meta tags automatically. Add alt to images (“WordPress Landing Page — Example”). Submit sitemap to GSC/Yandex.
4. Weak Security
   Mistake: No SSL, weak passwords, outdated plugins. 30 % of sites are hacked in the first year.
   How to Avoid: SSL from hosting (HostIQ.ua free). Wordfence plugin (free). Update WP/plugins monthly. Use 2FA for admin.
5. Image Overload
   Mistake: Photos 1–5 MB without compression — LCP > 4 s, PageSpeed < 70.
   How to Avoid: Convert to WebP (ShortPixel free). Add lazy-load in Elementor. Size < 100 KB per image.
6. No URL Structure and Menu
   Mistake: URLs like /post?id=123, menu not on all pages. Search engines get confused.
   How to Avoid: Pretty Permalinks (Post name). Menu in Elementor → Nav Menu. Add breadcrumbs (Yoast).
7. Ignoring Speed and Core Web Vitals
   Mistake: No minification, extra JS/CSS — FID > 100 ms.
   How to Avoid: Add defer JS in functions.php (code above). Test in PageSpeed — fix LCP/CLS/FID.
8. No Backups and Monitoring
   Mistake: Site “crashes” — everything lost.
   How to Avoid: UpdraftPlus (free) — backups to Google Drive. Jetpack for Uptime monitoring.
9. Poor Content and E-E-A-T
   Mistake: Short texts without keywords, no reviews. Google doesn’t trust.
   How to Avoid: 1500–3000 characters/page with keywords. Add reviews (Trustpilot), schema.org (FAQ).
10. No Integrations and Analytics
    Mistake: No GA4, Telegram notifications — leads lost.
    How to Avoid: Google Analytics 4 + MonsterInsights. Zapier for leads to Telegram.
