Before citing any number in an SEO context, it helps to understand where it came from. This page draws on three categories of evidence: publicly available search trend data (from tools like Google Trends and keyword research platforms), industry-wide estimates published by search marketing research organizations, and observed ranges from campaigns we've managed for interior design and adjacent professional-service firms.
Where a statistic comes from one of those sources, we say so. Where we're drawing on campaign experience, we use language like "in our experience" or "across the engagements we've run." We do not blend those categories or present observed ranges as universal benchmarks.
A standing disclaimer: Benchmarks vary significantly by market, firm size, and service mix. A boutique residential designer in a mid-size city competes in a fundamentally different search environment than a commercial fit-out firm in a major metro. Use these figures as orientation, not prediction.
If you see a precise percentage cited elsewhere without a named source and methodology, treat it with skepticism. SEO statistics for niche verticals are frequently recycled, outdated, or extrapolated from unrelated industries.
