Browser view-source
Right-click any page and choose "View page source" to see the raw title, a meta description, and Open Graph tags exist. It is free and instant, but you are reading raw markup by eye — easy to miss a missing alt or a broken canonical.
Developer tools
Browser DevTools let you inspect the DOM, check the rendered </code>, and test how tags look. More powerful than view-source, but still manual: you decide what is wrong, and there is no recorded report to compare later.</p>
<h2>Google Search Console</h2>
<p>Search Console shows how Google sees your pages, flags some HTML issues, and reports indexed URLs. It is free and authoritative for <em>Google's</em> view, but it focuses on what Google already crawled — it won't give you a clean PASS/WARN/FAIL checklist for tags you haven't published yet, and it isn't a per-page copy-paste scanner.</p>
<h2>Manual checklists and spreadsheets</h2>
<p>A written checklist (title present? meta present? one H1? alt on images?) works for learning and a first pass. The cost is repetition: a spreadsheet won't re-run itself, and consistency depends on whoever fills it in.</p>
<h2>Where a lightweight tool helps</h2>
<p>A tool like SEOAudit sits between "free but manual" and "expensive but heavy." You paste one page's HTML and get a deterministic PASS/WARN/FAIL report across 10 named rules, plus a ranked fixes list — reproducible enough to re-check after edits.</p>
<h2>Limits to keep in mind</h2>
<p>Free and paid tools alike only see what you give them. They check on-page tags, not content quality, backlinks, or rankings. Treat any result as a decision-support view, not a promise of where you'll rank.</p>
