How do I migrate from WordPress to Webflow?
The safe way is to rebuild the design in Webflow, move your content into Webflow's CMS, map every old URL to its new one with 301 redirects so you keep your search rankings, then point your domain across once everything is tested.
In practice it runs in four steps. First, the design gets rebuilt in Webflow, either as a fresh redesign or visually very close to what you have now, not always pixel-for-pixel, but close. Second, your content moves into Webflow's CMS, and blog posts can be imported in bulk via CSV rather than pasted one by one. Third, and this is the step that matters most, every old URL is mapped to its new one with 301 redirects. Fourth, everything is tested on a staging URL before your domain is pointed across, so the switch is clean.
The single thing that protects your SEO through a migration is that redirect map. Skipping it is the most common way a site loses traffic after a move, because search engines lose track of pages they'd already ranked. Done properly, you keep your rankings and gain a faster, easier-to-manage site.
One honest note on "pixel-perfect": a migration can look visually very similar to your current site, but I won't promise an exact clone. Usually that's a good thing, because it's a chance to fix what wasn't working.
