About CheckSite Websites & SEO

We help Niagara businesses get found and get hired.

CheckSite Websites & SEO — or just CheckSite for short — was built for one reason: too many great local businesses have terrible websites. We fix that with WordPress sites that load fast, rank high, and turn visitors into paying customers. Web development isn't just our job — it's our craft, and we love it.

Les Corrigan — Principal Developer & Owner

Les is the principal developer and owner of CheckSite Websites & SEO. He's the one writing the code, tuning the SEO, and picking up the phone when you call.

We're based in St. Catharines, Ontario and have been building WordPress websites and ranking Niagara businesses on Google since 2002— over two decades of local web development experience right here in the Niagara Region.

Talk to Les Directly

Built by people who genuinely love web development — and actually answer the phone.

CheckSite Websites & SEO isn't a faceless agency in another country. We're a small, tight-knit Niagara team of web designers, WordPress developers, SEO specialists, and conversion nerds who care a lot about your business doing well — and who genuinely get a kick out of the work itself.

Web development is a craft we're obsessed with. We sweat the details most agencies skip: hand-coded templates instead of bloated page builders, accessibility baked in from the start, Core Web Vitals tuned until PageSpeed scores live in the 90s, schema markup written by humans, and clean WordPress builds that you'll actually be able to update yourself five years from now. CheckSite was founded on the belief that small business websites deserve the same engineering care that enterprise products get.

Over the years, CheckSite has worked with contractors, limo companies, real estate agents, home services, restaurants, professional offices, and dozens of other local operators across St. Catharines, Niagara Falls, Welland, Thorold, Niagara-on-the-Lake and the rest of the region. We know the Niagara market because we live in it — your customers are our neighbours, and we treat every project like the storefront of someone we'd bump into at the grocery store.

The pattern is always the same: a beautiful website on its own doesn't grow a business. A website built around how customers actually buy — combined with steady, transparent SEO and a team that picks up when you call — does. That's the entire reason CheckSite Websites & SEO exists, and it's what every project we ship is engineered to deliver.
