SDO is a web design company in Markham building custom, responsive, SEO-ready websites for local businesses — sites that load fast, rank on Google, and turn visitors into paying customers.
Markham is one of the most competitive business markets in the GTA — home to thousands of tech firms, clinics, retailers, restaurants, and professional services all competing for the same local customers. A generic website simply doesn't cut it here.
As a web design agency in Markham, we build custom, mobile-first websites optimized for local search — so people searching in Unionville, Cornell, Berczy Village, and Thornhill find your business first, not your competitor's.
Local keywords, Google Business Profile setup, and map-pack optimization built into every site.
Everything a local business needs to look credible online and get found in Markham searches.
A one-of-a-kind site designed around your Markham business - built to stand out from competitors using the same tired templates.
Easy-to-manage WordPress sites you can update yourself - add staff, services, or promotions without calling a developer.
Online stores for Markham retailers - Shopify and WooCommerce builds with smooth checkout, local pickup, and delivery options.
Focused pages for your Google or Meta ads - built to capture leads from local campaigns instead of losing the click.
Still running a site from 2015? We'll modernize the design, speed it up, and make it work properly on mobile.
Google Business Profile setup, local keywords, and map-pack optimization - so Markham customers find you before your competitors.
