The verdict in three sentences
Migrating from WordPress to Next.js turns a slow, exposed site into a fast, secure one: LCP cut by 2 to 3x and a Lighthouse score climbing from 55 to 95+. The attack surface drops by around -70 % because there are no more plugins or front-facing database. But beware: for a simple, heavily-updated blog run by a non-technical editor, staying on WordPress can still be the smarter call.
WordPress vs Next.js: the quantified comparison
Both approaches serve different needs. Here's the performance and security gap observed in 2026.
| Criterion | Typical WordPress | Next.js |
|---|---|---|
| LCP (load) | 3.5 - 4.5 s | 1.2 - 1.8 s |
| Mobile Lighthouse score | 45 - 60 | 90 - 100 |
| Attack surface | high (plugins, DB) | reduced (-70 %) |
| Hosting cost / month | 25,000 - 75,000 FCFA | 0 - 30,000 FCFA |
| Security updates | weekly | rare |
| Content editing | very easy | via headless CMS |
The main trade-off is content editing: WordPress remains unbeatable for a non-technical editor publishing daily. Next.js with a headless CMS (Sanity, Strapi) closes that gap, but adds a layer to set up.
Migration cost and SEO preservation
A botched migration can destroy rankings. The key is preserving URLs via 301 redirects. Here are the 2026 orders of magnitude.
| Item | Timeline | Indicative 2026 price (FCFA) |
|---|---|---|
| Showcase site migration (< 20 pages) | 15-20 days | 800,000 - 1,300,000 |
| Site + blog migration (< 100 pages) | 20-30 days | 1,300,000 - 2,000,000 |
| Migration + headless CMS | 25-35 days | 1,800,000 - 2,500,000 |
| 301 redirect plan | included | preserves 90-100 % of SEO |
An exhaustive 301 redirect plan is non-negotiable: it maps each old URL to the new one and preserves 90 to 100 % of SEO equity. Without it, organic traffic can drop 30 to 50 % within weeks.
Mini case study
Seydou runs a consulting firm in Dakar. His WordPress site loaded in 4.2 s, scored 52 on Lighthouse, and suffered two hacking attempts a month via outdated plugins.
After migrating to Next.js at 1,500,000 FCFA, LCP drops to 1.4 s, the score climbs to 97, hosting goes from 50,000 to 10,000 FCFA/month (-480,000 FCFA/year) and security incidents vanish. Organic traffic, preserved via 301 redirects, even rises +22 % in three months thanks to better Core Web Vitals.

FAQ
Will I lose my rankings by migrating?
No, if an exhaustive 301 redirect plan is in place. It points each old URL to the new one and preserves 90 to 100 % of SEO equity. It's the most critical step of the migration.
How much does a WordPress-to-Next.js migration cost?
From 800,000 FCFA for a showcase site under 20 pages to 2,500,000 FCFA for a site with a blog and headless CMS. The timeline runs 15 to 35 working days.
Will I still edit content easily?
Yes, with a headless CMS (Sanity, Strapi) offering an editing interface as simple as WordPress, while keeping Next.js performance on the front end.
When is it better to stay on WordPress?
If you have a very active blog edited daily by a non-technical person, with no critical performance stake, an optimized WordPress (cache, CDN) may suffice and cost less in the short term.
What's the concrete security gain?
Next.js cuts the attack surface by roughly 70 %: no third-party plugins, no front-facing database, and far rarer security updates than WordPress's weekly patches.
