What's Actually Changed in Web Standards Since 2015

A site built a decade ago was built to a genuinely different set of expectations — knowing what's changed helps prioritise what to fix.

A site built a decade ago was built to a genuinely different set of expectations — not just aesthetically dated, but built against baseline standards that have since shifted substantially, in ways that matter commercially, not just visually.

Mobile-first is now the baseline, not an extra

In 2015, "mobile-friendly" was still often treated as a secondary consideration to a desktop-first design. Today, for most industries, the majority of traffic is mobile — a site not genuinely designed mobile-first is failing its primary audience, not a secondary one.

HTTPS is expected, not optional

What was once an optional security enhancement is now a baseline trust and ranking signal — a site still on HTTP actively triggers browser security warnings that actively damage credibility on first load, an issue that essentially didn't exist a decade ago.

Page speed expectations have risen significantly

Visitor patience for slow-loading pages has measurably decreased as broadband and mobile connections have improved elsewhere — a load time that was acceptable in 2015 now reads as genuinely slow relative to current visitor expectations.

Accessibility has moved from niche to expected

Accessibility considerations that were once a specialist, often-skipped concern are increasingly a baseline expectation — both from visitors and, in a growing number of jurisdictions, from a legal compliance standpoint that simply didn't apply the same way a decade ago.
