rankd — Content Quality Scorer

rankd — Content Quality Scorer

Details
View on WordPress

rankd scores the post you are writing on a 0-100 quality scale, in the editor sidebar. Six axes — readability, structure, length, links, images, title — plus actionable suggestions on what to fix before you hit publish.

The plugin connects to your rankd account. Each WordPress verdict uses the same rankd quota as the web product: free accounts get 2 verdicts per day; Pro gets 500 verdicts per month.

What it does

  • Editor sidebar verdict — opens as a meta box on every post and page edit screen
  • Six axes scored 0-100 — readability, structure, length, links, images, title
  • Actionable suggestions — short, specific, ranked by impact
  • Quota-aware — runs only when you click, so typing does not burn verdicts
  • Works in Gutenberg and Classic Editor — auto-detects which one you are using

External service and pricing

This plugin sends the post title, post content, and site URL to https://rankd.voiddo.com/api/wp/content-score when you click run rankd verdict. It does not send content while you type. It does not write post meta, publish content, or alter your post.

A rankd account and WordPress API token are required. Free rankd accounts include 2 verdicts per day. rankd Pro includes 500 verdicts per month and is available at $4.99/month or $49.99/year. Pricing and quota may be changed on the rankd pricing page, and the active quota returned by rankd is shown after each verdict.

Why a sidebar scorer

Existing SEO plugins focus on keyword targeting and serialize their advice across multiple panels. rankd answers a different question: “is this post structurally good before I worry about keywords?” — readability, sectioning, link density, image alt text, title length. The basics that lift any post regardless of niche.

Six axes scored

  • Readability — sentence length and word complexity (lower is easier)
  • Structure — H2/H3 distribution and section count
  • Length — sweet-spot around 800-2000 words; penalty at the extremes
  • Links — outbound + internal density (1 per ~250 words is healthy)
  • Images — at least one image with alt text on posts over ~200 words
  • Title — 30-65 characters is the SEO sweet spot

The composite is a weighted average; each axis is exposed individually so you can see what is dragging.

How it differs from generic readability tools

  • Lives where you write — the WordPress editor sidebar — not a separate site
  • Uses the same rankd quota and upgrade path as the main product
  • Runs on explicit click only — no quota burn while typing
  • Keeps the verdict separate from publishing — you decide what to change
