Next.js vs WordPress for a SaaS Marketing Site

This debate is usually argued on taste. Here's the version that matters to a founder deciding where the marketing site lives.

Speed, and why it's a revenue issue

A Next.js marketing page is pre-rendered to static HTML and served from a CDN edge near the visitor. A typical WordPress page is assembled per request by PHP hitting MySQL, then patched up with a caching plugin.

Well-tuned WordPress can be fast. The problem is that it rarely stays fast: every plugin adds CSS and JavaScript to the critical path, and a year of small additions quietly doubles your load time. Static output doesn't drift like that.

This matters because Core Web Vitals influence rankings, and because paid traffic is expensive — if a tenth of your ad clicks bounce before the hero renders, you're funding your competitors' auction prices.

SEO: a closer race than developers admit

WordPress with Yoast or RankMath gives a non-technical marketer excellent SEO tooling: redirects, meta editing, schema, readability prompts, all without a developer. That's a genuine advantage and it's why WordPress is still everywhere.

Next.js gives you the same capabilities through code — per-page metadata, generated sitemaps, canonicals, structured data, image optimisation — which is cleaner and faster but requires a developer for anything structural. If nobody on your team writes code, that's a real operational cost.

The argument that actually decides it for SaaS

Your product is almost certainly React. If your marketing site is also React, then your design system, components, types and tooling are shared — a button restyle applies everywhere, and the login page doesn't look like it belongs to a different company.

With WordPress you maintain two stacks, two deploy pipelines and two design implementations that drift apart every quarter. For a small team that's a meaningful ongoing tax, and it's the most honest reason to pick Next.js for SaaS specifically.

When WordPress is the right call

• No developer on the team and no budget for one on retainer.
• A marketer who must publish and restructure pages daily without waiting on anyone.
• A content-heavy operation — hundreds of posts, multiple authors, editorial workflow already established.
• You need membership, forums or e-commerce tomorrow and a plugin solves it today.

Those are good reasons, not compromises. A fast WordPress site that your team can actually update beats an elegant Next.js site nobody can edit.

What a migration really involves

1. 1Export every URL from Search Console, sorted by clicks.
2. 2Map old URLs to new ones and write the 301 redirects before launch, not after.
3. 3Move content into the new CMS, preserving titles, meta descriptions and canonical tags.
4. 4Keep image filenames and alt text — image search traffic is easy to lose and hard to notice.
5. 5Launch, then re-crawl and check for 404s and redirect chains in the first week.

Done properly, rankings dip for a week or two and recover. Done carelessly, you lose traffic that took years to build, and the cause is almost always missing redirects.
