WordPress to Webflow: what actually protects your SEO

Most migration horror stories are not platform problems. They are redirect problems, and they are avoidable with a map written before anything moves.

Replatforming is where search equity goes to die — not because the new platform is worse, but because nobody wrote down where every old URL was supposed to land. The fix is unglamorous and entirely procedural.

Write the redirect map before you build

Export every indexed URL from the existing site, not just the ones in the navigation. Old campaign pages, orphaned blog posts and parameter variants all carry equity you already paid for. Each one needs a destination on the new site, chosen deliberately rather than dumped on the homepage.

A homepage catch-all is the single most common mistake. It tells search engines the page is gone and the replacement is generic, which is exactly the signal you do not want.

Keep the content model, improve the structure

Webflow CMS gives you a chance to model content properly rather than reproducing a decade of WordPress categories. Take it — but do it as a deliberate mapping exercise, so the new collection fields carry the same semantics the old taxonomy did.

Measure the window, not the launch

Migration effects show up over two to six weeks, not on day one. Hold a baseline of impressions and rankings before the switch, then watch the same set afterwards. Without the baseline you cannot tell a seasonal dip from a structural mistake.

This is the part clients are rarely offered, and it is the part that turns a replatform into a measurable improvement rather than a leap of faith.
