RankParse SEO Toolkit EN

RankParse SEO Toolkit is a free SEO Edge extension that gives you instant on-page SEO analysis, domain authority scores, backlink data, and SERP metrics - all without leaving the page you're on.

Used by SEOs, content marketers, and developers who want a fast, no-bloat alternative to bulky SEO toolbars.

FREE ON-PAGE SEO ANALYSIS
──────────────────────
Run a full SEO audit on any webpage instantly:

• Meta tag analyzer — checks title length, meta description, and OG tags; flags missing values
• Canonical tag checker — detects non-self canonicals that bleed link equity to other URLs
• Robots meta tag inspector — surfaces noindex and nofollow directives immediately
• Heading structure audit — H1, H2, and H3 counts with H1 text preview
• Image SEO audit — finds every image missing alt text, with width × height dimensions
• Link analysis — total, internal, external, dofollow, nofollow, sponsored, and UGC link counts
• Broken link checker — HEAD-checks up to 20 external links on demand, no server needed
• Schema markup detector — confirms whether structured data is present on the page

No API key required. All page-level analysis runs locally in your browser.

DOMAIN AUTHORITY CHECKER + BACKLINK CHECKER
──────────────────────
Connect your free RankParse API key to unlock:

• Domain Authority score (DA 0–100) — built on open database link graph, updated quarterly
• Backlink count and referring domain count for any site

• Domain age and registrar lookup (via RDAP)
• Top 100 backlinks with per-domain DA scores and anchor text — exportable to CSV

Results are cached for 24 hours. You're never charged twice for the same domain.

No API key? The free tier shows DA + backlinks for up to 10 domains per day at no cost.

SERP SEO METRICS — GOOGLE SEARCH INTEGRATION
──────────────────────
• Domain authority scores appear directly on Google search results for all 10 organic listings
• Built-in SERP country and language switcher — flip the gl/hl parameters without editing the URL

PERSISTENT METRICS BAR
──────────────────────
Enable the metrics bar to show DA, backlinks, and referring domains pinned to the top of every site you visit — no popup needed.

WHY RANKPARSE?
──────────────────────
Most SEO browser extensions are either paywalled from day one or rely on expensive third-party APIs that inflate pricing. RankParse is powered by open source public databases — which lets us offer real backlink and domain authority data at a fraction of the cost of Ahrefs, Moz, or Semrush browser extensions.

──────────────────────
PRIVACY & DATA
──────────────────────
• On-page SEO analysis runs entirely in your browser — zero data leaves your device
• Domain data is only fetched from api.rankparse.com when you explicitly request it
• No browsing history is stored or transmitted
• Your API key is saved locally in storage — never sent to any third party
