Who builds custom websites on Long Island? Designs By Dave O., a Roslyn Heights agency designing and developing conversion-first sites since 2007. We design around your customers’ buying journey, build on WordPress, Shopify, or Next.js, and stay on after launch to host, maintain, and grow the site.

A website that earns its keep.
Your website is your hardest working employee. It greets every prospect, answers questions at 2am, and closes business while you sleep. But only if it was built to. Most websites are built to look good in a portfolio. We build websites that are engineered to convert: structured around how your customers actually buy, written to answer what they actually ask, and measured so you know exactly what is working.
Every project starts with strategy, not colors. We learn your business, your customers, and your competition. Then we design from a blank canvas, develop on the platform that fits (WordPress for content driven sites, Shopify for retail, Next.js for performance critical builds), and launch with analytics, conversion tracking, and clean redirects in place. Nothing is templated. Everything is measured.

What businesses ask about website design & development.
How long does a website take from start to launch?
Most projects run 6-10 weeks. Strategy, design, development, and launch. E-commerce and custom applications can take longer; we set a real timeline in your proposal.
Which platform should my business use?
It depends on your content, commerce, and team. WordPress for content-heavy marketing sites, Shopify for retail, Next.js for performance-critical or custom applications. We recommend after a discovery call.
Do you redesign existing websites?
Yes. Much of our work is modernizing existing sites while preserving SEO equity through proper redirects and content mapping.
Will I be able to edit the site myself?
Yes. We build with editor-friendly tooling and provide training so your team can manage day-to-day content.
What makes a website "high-converting"?
Clear messaging above the fold, one primary call-to-action, fast load times, trust signals, and friction-free forms. Standard in every build we ship.
