Most audits fall short because they treat your site like a static document instead of a dynamic ecosystem. The checklist from shortlist.io nails this – their “50+ things” approach forces you to think beyond the obvious. You can’t just verify canonical tags exist and call it a day. Crawlability isn’t binary.
Start with crawl budget starvation. Use Screaming Frog or DeepCrawl to simulate search engine bots. If your homepage has 20 internal links pointing to low-value product variants, those bots are wasting cycles clicking through them instead of finding your best content. Clean up the internal architecture before Google even gets there.
Then audit your robots.txt. A single malformed rule can block access to critical assets like /api/product-data or /images/hero-banner.jpg, killing both indexing and page speed signals. GRM Digital rightly flags this as foundational. Test it live with curl -I https://yoursite.com/robots.txt to see what Google sees.
Finally, never ignore renderability. Even if Lighthouse reports 98/100, check real-world rendering with Chrome DevTools’ Coverage tab or Puppeteer headless tests. A site claiming fast load times but serving unstyled HTML to crawlers is lying to everyone – including its own conversion funnel.
Run these checks monthly, not annually. Technical debt compounds faster than you realize. Your next audit should break more problems than it fixes.
