Squarespace is a capable platform. It handles SSL, mobile responsiveness, and clean URL structures out of the box. But capable doesn't mean optimized. The platform makes design easy and SEO optional — which means most users ship sites with a stack of avoidable mistakes baked in from day one.
The mistakes on this page aren't exotic edge cases. They're the patterns we see repeatedly when auditing Squarespace sites: settings left at defaults, features used without understanding their crawling implications, and content structures that confuse Google's indexer.
The good news: almost everything here is fixable. The bad news: some of these mistakes compound over time. Every month Google crawls a misconfigured site is another month of ranking potential lost. If you've been wondering why your Squarespace site isn't showing up where you'd expect it to, the answers are likely somewhere in this list.
A note on severity: not every mistake here carries the same weight. We've grouped them roughly from most damaging to easiest to overlook, but your specific situation matters. A site with thin content and a cover page blocking crawlers has a different priority order than a site with solid content but missing schema. Read through all ten before deciding where to start.
