A focused technical analysis that follows Google Search Essentials and prioritises issues by real impact.
The analysis process
1. Fetch and crawl
We request the submitted URL and follow internal links within reasonable limits.
2. Parse signals
On each page we extract title tags, meta descriptions, heading hierarchy, canonical tags, meta robots, structured data, and key performance indicators.
3. Apply rules
Findings are evaluated against a single clear H1, sequential heading nesting, unique metadata, valid structured data, and Core Web Vitals thresholds: LCP at or under 2.5s, INP at or under 200ms, CLS at or under 0.1.
4. Prioritise and report
Issues are grouped as Critical, Warning, or Notice. Each item includes a plain-language explanation and a recommended next step.
What we deliberately leave out
Syniic is a technical checker, not a full SEO suite. We do not currently analyse backlink profiles, keyword rankings, or content quality scores.
