Website makeover

A complete makeover of your current website without losing the Google position you've built up. New look, new foundation, same address — and usually more visitors.

Modern design, better typography and subtle motion — a website you're happy to share.

Keep your Google position

Every old page is pointed to the new one, and I keep an eye on your rankings for 30 days after launch.
