SEO Fundamentals
Core SEO definitions and quality checks for understanding links, authority metrics, crawlability, and search visibility without shortcuts.
Start with definitions that match how search evidence is measured
This hub collects foundational SEO concepts that often get misused in link building reports. Use it to separate Google-owned evidence from third-party metrics, understand what links can and cannot prove, and keep strategy grounded in verifiable page-level checks.
Concept rules
- -Use Google Search Console for actual Google performance evidence; use third-party crawlers for discovery and prioritization.
- -Treat backlinks as references that need context: source quality, relevance, anchor text, rel attributes, canonical behavior, and whether the source page is indexable.
- -Use Domain Rating and similar scores as comparative crawler metrics, not as Google authority scores or guaranteed ranking inputs.
- -Prefer clear definitions, source review, and practical verification over private-system speculation or one-number SEO claims.
Evidence checks
- -Can the claim be verified from a live URL, Search Console export, crawl result, or documented Google policy?
- -Does the page explain what the metric measures and what it does not measure?
- -Are link attributes, canonical tags, noindex signals, and redirects checked before judging a backlink?
- -Does the recommendation reduce risk and improve decision quality, or only inflate a vanity metric?
