The fastest technical SEO wins are the ones that fix obvious errors or add missing signals Google already wants. Start with broken links—run a crawl with Screaming Frog or Sitebulb, export any 404s from internal links, and either redirect or fix them. This usually takes under an hour for sites with fewer than 500 pages and stops you from wasting crawl budget on dead ends. Next, tackle image optimization. Download your ten highest-traffic pages, check if images are over 200KB, and compress them with TinyPNG or ShortPixel. Add descriptive alt text to any image missing it—this helps accessibility and gives Google more context. For an e-commerce site, this alone can shave 1–2 seconds off load time. Schema markup is low-hanging fruit that most sites ignore. Add Organization schema to your homepage, Article schema to blog posts, or Product schema to store pages. Google's Rich Results Test will tell you if it's valid. You don't need to mark up everything—focus on your money pages. We've seen CTR lifts of 15–30% when star ratings or FAQ snippets appear in search results. Other quick wins: - Submit or update your XML sitemap in Google Search Console if you haven't in six months - Fix duplicate title tags and meta descriptions flagged in GSC's Pages report - Enable HTTPS if you're still on HTTP (2024 and beyond, this is non-negotiable) - Add canonical tags to paginated archives or filtered product pages - Check mobile usability in GSC and fix any tap-target or viewport issues At Ottawa SEO, we run a technical audit checklist on new client sites and knock out these fixes in the first week. The goal isn't perfection—it's removing obstacles so Google can crawl, understand, and rank your content without friction. Most of these changes cost zero dollars and require basic CMS access or a developer for 2–3 hours. You'll see indexing improvements in days and ranking movement in 3–8 weeks depending on crawl frequency.
