Wix SEO Performance in 2024 and 2025: A Quiet Shift in the Data

For a long time, discussions about website platforms and SEO have been shaped more by reputation than evidence. Wix, in particular, has often been talked about using assumptions that no longer reflect how the platform actually performs.

Independent data now tells a clearer story.

According to the HTTP Archive Web Almanac, Wix was the only CMS to achieve a perfect median Lighthouse SEO score of 100 on both desktop and mobile in 2024 — and then repeat that result again in 2025.

Two consecutive years.

That matters, not because Lighthouse scores equal rankings, but because this research looks at how platforms perform in the real world, across millions of live websites, using a consistent methodology. This isn’t a showcase of best-in-class builds or carefully curated examples. It’s a reflection of what typical sites on each platform are actually delivering.

What stands out is not that Wix can perform well — that has been true for some time — but that it does so consistently at the median level. In both reports, other major platforms such as WordPress, Shopify and Squarespace show strong results, but none match Wix’s ability to hold a perfect median score across both years and both device categories.

A median score is important because it removes edge cases. It tells us less about what’s technically possible with unlimited customisation, and more about what businesses are likely to get in practice. In that context, Wix’s results point to solid technical SEO foundations being built into the platform as standard, rather than achieved through heavy intervention.

It’s also worth being clear about what this does — and does not — imply. A high Lighthouse SEO score doesn’t guarantee search visibility, nor does it replace the need for clear structure, intent-led pages, credible content or strong internal linking. SEO outcomes are still driven by strategy, clarity and relevance. What this data shows is that the platform itself is no longer a limiting factor.

For businesses making platform decisions in 2026, that distinction matters. The long-running debate about whether Wix is “SEO-friendly” is increasingly redundant. The more relevant question is whether a website is structured properly, communicates authority, and makes it easy for the right users to take the next step.

When a Wix site underperforms today, the cause is far more likely to be messaging, structure or content than technology. Pages targeting the wrong intent, thin service descriptions, weak internal linking or unclear calls to action will hold a site back on any platform.

The Web Almanac results from 2024 and 2025 don’t change how SEO works.

What they do change is the conversation. Wix has quietly removed itself from the list of technical constraints — leaving strategy, not software, as the deciding factor.
