rankd — Content Quality Scorer
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

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
