Technical SEO: making sure Google can actually read your site
Most SaaS sites are JavaScript SPAs that render an empty `<div id="root"></div>` to crawlers. Google figures it out eventually — but the AI crawlers (ChatGPT, Perplexity, Claude) don't render JavaScript at all, so a React-only site is invisible to them. Add to that broken canonicals, app-subdomain pages bleeding into the index, and bloated crawl budgets, and you have a foundation that quietly kills every other SEO effort. The fix is unglamorous: server-side render the public pages, ship a clean sitemap, tighten internal linking, and add schema so Google knows you're a SoftwareApplication and not a blog. Get this right once, and every blog post and link you build afterward compounds. Skip it, and you'll spend years wondering why your competitors outrank thinner content.
