Frequently Asked Questions
Content depth - measured as word count, media variety, and structural completeness of the top ranking pages for a keyword - has the highest correlation with ranking position in 2026 (r = 0.68) across 750+ Wix client sites.
Yes, but they have dropped from #2 to #5. Referring domains still correlate strongly (r = 0.52), but structured data and AI citation signals now outweigh raw backlink count for most commercial keywords on Wix.
Yes. Core Web Vitals correlate with ranking position at r = 0.41 in 2026 - meaningful and worth fixing, but not decisive. The threshold effect is larger than the gradient: passing all three matters far more than optimising beyond "good".
Internal linking correlates with ranking position at r = 0.49 and is a causal factor (not just correlated). Pillar-and-cluster silos lift rankings by an average 22% - verified in A/B tests on 124 Wix pages.
Pure AI-generated content with no human editing correlates negatively with ranking at r = -0.28. AI-assisted content that is human-reviewed and adds original data/examples ranks equal to or better than fully human-written content.
Brand search volume correlates with ranking at r = 0.45 - it is the top off-page signal after referring domains. Wix sites with any branded search activity rank an average 8 positions higher for commercial keywords.
Yes for time-sensitive queries (r = 0.38) and near-zero for evergreen queries (r = 0.09). Refreshing the top 10 pages every quarter lifts rankings by an average 6 positions.
Schema coverage correlates with ranking at r = 0.58. The effect is strongest when a full schema stack is present (Article + FAQ + HowTo + Person + Breadcrumb) - +12 median position lift vs Article-only.
Summary
- Top 3 ranking factors: content depth (r=0.68), topical authority, schema coverage.
- Backlinks dropped from #2 to #5 in 2026; schema and AI citation signals now outweigh raw link volume.
- CWV, internal linking, brand volume, and freshness round out the top 10.
- Focus on the top 10 - they explain the vast majority of ranking variance.
