Vista Web Tool

Vista web tool provides a real-time SEO health assessment for public websites. It solves the need for quick, structured insight into on-page and technical factors, enabling SEOs, webmasters, and content teams to identify issues, quantify impact, and prioritize fixes. It operates without private access, relying on public page content, headers, structured data signals, and performance metrics to drive actionable guidance.
It analyzes the input URL and applies a taxonomy of checks across on-page signals (title tag length and relevance, meta description quality, H1/H2 usage, image alt attributes, canonical links, hreflang presence), technical signals (robots.txt status, sitemap availability, canonicalization, crawlability, structured data coverage, mobile-friendliness), and performance indicators (speed index, largest contentful paint, time to first byte). The tool returns an overall SEO score plus sub-scores for on-page, technical, and content quality, plus a prioritized list of issues and recommended actions.
Required input is a single URL string with validation. Outputs include overall_score, on_page_score, technical_score, content_score, issues array, and actions array; formatting rules ensure numbers are 0-100 and issues reference specific checks.
Scoring combines independent checks with weighted factors: keyword presence and tag validity (0.25), metadata quality (0.25), structural signals (0.15), performance metrics (0.15), accessibility and crawlability (0.1). Ranges map to 0-100; ideal lengths and presence thresholds defined by industry guidelines.
Assumptions & Exclusions: Only publicly accessible pages are analyzed; no login-protected content; data is indicative, not a guaranteed ranking predictor; historical trend data is optional and not assumed by default.
