A Website Development Company That Builds for Results
Your website is usually the first conversation a customer has with your business. If it loads slowly, looks dated on a phone, or can't be found on Google, that conversation never happens. We build custom websites that fix all three: fast, modern, and structured from the first line of code to rank in search.
PrimaryDM is a small, senior team of developers based in Mississauga and Sault Ste. Marie, Ontario. We have built more than 500 websites for service businesses, professional firms, e-commerce brands and non-profits across Canada and the US. Every project is designed and developed in-house, and you work directly with the people writing your code.
We are not tied to one platform. We build on WordPress when you want to manage content yourself, on Shopify and WooCommerce when you sell online, and with React when your site needs custom features an off-the-shelf theme can't handle. We recommend the platform that fits your goals and budget, not the one that's easiest for us.
Included in every website we build
- Custom design built around your brand
- Mobile-first, responsive layouts
- On-page SEO and schema markup
- Core Web Vitals and speed optimization
- Google Analytics and Search Console setup
- Contact forms and lead tracking
- Training so your team can edit content
- Launch support and post-launch fixes

How we build SEO into every website
Keyword research first
We map the searches your customers actually use to specific pages before design starts, so every page has a job to rank for.
Fast Core Web Vitals
Optimized images, clean code and caching keep load times low. Google rewards fast sites, and so do visitors.
Technical SEO done right
Clean URLs, XML sitemaps, canonical tags, structured data and proper heading structure, all handled at build time.
Local SEO
Location pages, Google Business Profile alignment and local schema help you show up in the map pack in your area.
Content that converts
Pages written for people and search engines alike, with clear calls to action that turn visitors into leads.
Tracking from launch
Google Analytics and Search Console are set up on day one, so you can see rankings, traffic and leads grow.
Our Website Development Process
A clear, proven process that keeps your project on schedule and on budget, with no surprises along the way.
Discovery
