Technical SEO is everything you do to make your website easier for search engines to access, read, and rank—separate from the actual content or links. Think of it as the foundation and plumbing. You can have brilliant content, but if Google's crawlers can't reach it, load it fast, or understand your site structure, you won't rank. The core areas include site speed (Google uses Core Web Vitals as ranking signals now), mobile responsiveness (most traffic is mobile), crawlability (your robots.txt and XML sitemap tell Google what to index), indexability (making sure pages aren't blocked by noindex tags or canonicals pointing the wrong way), HTTPS security (non-secure sites get demoted), and structured data markup so Google understands your content type—whether that's a local business, product, or article. Common technical issues we fix at Ottawa SEO include duplicate content from URL parameters, broken internal links that waste crawl budget, slow server response times (especially on shared hosting), missing alt text that hurts accessibility and image search, redirect chains that slow everything down, and orphaned pages with no internal links pointing to them. A site audit tool like Screaming Frog or Sitebulb surfaces most of these quickly. Why it matters: Google's crawler has a budget. If your site has 5,000 pages but half are thin or broken, you're wasting crawl on junk instead of your money pages. We've seen 30–60% traffic jumps just from cleaning up technical debt—no new content required. For ecommerce or large portfolios like ours, technical SEO scales your ability to rank thousands of pages without manually optimizing each one. You don't need to be a developer. Most technical SEO is configured in your CMS, hosting panel, or plugins. The key is regular audits—quarterly if you're growing fast, twice a year minimum. Fix the highest-impact issues first: crawl errors, site speed, mobile usability. Those move the needle faster than obsessing over schema markup for every page.
