SEO Score

SEO Score — Instant On-Page SEO Analyzer for Any Webpage Analyze any webpage's SEO in one click. SEO Score runs 37 professional-grade checks across 6 categories, scores the page out of 100, and gives you clear, actionable recommendations to fix every issue — all without leaving your browser. No accounts. No subscriptions. No data sent anywhere. Everything runs client-side, directly in your browser. ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ WHY SEO SCORE? Most SEO tools want your email, your credit card, or your patience while they spin up a server somewhere to crawl a page you're already looking at. SEO Score takes a different approach: it reads the page already loaded in your tab, runs every check locally, and gives you a score in milliseconds. No network requests. No cloud processing. No waiting. Whether you're a developer shipping a site, a content writer checking your latest post, a marketer auditing a landing page, or an SEO professional running a quick sanity check — SEO Score gives you the answer instantly. ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ WHAT YOU GET One click opens a dark, professional interface showing: A score out of 100 displayed in an animated ring, color-coded: green for 80+, amber for 50–79, red for below 50. You know instantly where you stand. Six category breakdowns with progress bars and fraction scores so you see exactly which areas need attention: Meta Tags, Headings, Content, Social Media, Technical, and Performance. 37 individual checks — each shows a pass, warn, or fail status with the actual value found on the page and a specific recommendation for how to fix it. No vague advice. Every recommendation is tied to what the check actually found. The worst-performing category auto-expands so you see the most critical issues first. Click any category bar to jump to its detail section. Collapse and expand as you work through each issue. Analysis time displayed in the footer in milliseconds. ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ EVERY CHECK — IN DETAIL SEO Score runs 37 checks organized into 6 categories. Points add up to 100. ────────────────────────────────── META TAGS — 20 Points (8 checks) ────────────────────────────────── Covers the foundational HTML metadata that search engines read first when crawling your page. Title Exists (4 pts) — Verifies a non-empty title tag is present. The title tag is the single most important on-page SEO element. It appears in search results, browser tabs, and social shares. Title Length (4 pts) — Measures character count. Pass: 30–60 chars. Warn: 20–29 or 61–70. Fail: outside range. Search engines truncate titles beyond 60 characters. Meta Description Exists (3 pts) — Checks for a non-empty meta description. The description appears as snippet text in search results and directly affects click-through rate. Description Length (3 pts) — Pass: 120–160 chars. Warn: 80–119 or 161–200. Fail: outside range. Google typically displays 150–160 characters on desktop. Canonical URL (2 pts) — Checks for link rel="canonical". Without it, you risk splitting ranking power across duplicate pages. Meta Robots (1 pt) — Reads meta robots for noindex/nofollow directives. A noindex tells search engines not to index the page — critical if unintentional. Viewport Meta (2 pts) — Checks for viewport with width=device-width. Essential for mobile responsiveness. Google uses mobile-first indexing, so this directly impacts rankings. Charset (1 pt) — Verifies character set declaration via meta charset or http-equiv. Without it, browsers may misinterpret special characters. ────────────────────────────────── HEADINGS — 15 Points (4 checks) ────────────────────────────────── Evaluates heading structure (H1–H6) for content hierarchy and accessibility. H1 Exists (5 pts) — Pass: exactly one H1. Warn: two or more. Fail: none. The H1 is the primary heading and should clearly describe the page's main topic. H1 Length (3 pts) — Pass: 20–70 chars. Warn: 10–19 or 71–100. Fail: outside range. An effective H1 is concise but descriptive. Heading Hierarchy (4 pts) — Checks for skipped heading levels (e.g., H2 to H4). Pass: none skipped. Warn: one skip. Fail: two or more. Proper hierarchy helps search engines and screen readers. Heading Count (3 pts) — Pass: 2–15 headings. Warn: 1 or 16–30. Fail: 0 or 30+. Too few means no structure; too many dilutes significance. ────────────────────────────────── CONTENT — 20 Points (6 checks) ────────────────────────────────── Evaluates substance, linking, and image optimization. Word Count (5 pts) — Pass: 300+ words. Warn: 100–299. Fail: under 100. Thin content struggles to rank because it lacks substance for search engines to evaluate. Internal Links (3 pts) — Counts same-domain links. Pass: 3+. Warn: 1–2. Fail: 0. Internal links distribute link equity and help crawlers discover pages. External Links (2 pts) — Counts links to other domains. Pass: 1+. Fail: 0. External links to authoritative sources signal well-researched content. Images Alt Text (5 pts) — Checks percentage of images with non-empty alt attributes. Pass: 100%. Warn: 50–99%. Fail: under 50%. Critical for accessibility and image search traffic. Has Images (2 pts) — Pass: 1+ images. Fail: none. Pages with images have lower bounce rates and can appear in image search. Anchor Links Valid (3 pts) — Verifies in-page anchor links (#) point to existing IDs. Pass: all resolve. Warn: 1 broken. Fail: 2+ broken. ────────────────────────────────── SOCIAL MEDIA — 10 Points (6 checks) ────────────────────────────────── Checks Open Graph and Twitter Card meta tags that control social share previews. og:title (2 pts) — The title shown when shared on Facebook, LinkedIn, and other Open Graph platforms. og:description (2 pts) — The description text in social share previews. og:image (2 pts) — The preview image for social shares. Posts with images receive significantly more engagement. og:url (1 pt) — Canonical URL …
