RankStudio SEO scores your article with adeterministic 0-100 Scorebuilt on 5 pillars with public weights, gets it ready tocompete for AI Overviews citations—a roughly 40-60 word passage with verifiable data— and checks that your ad and your pagepromise the same thing.
Everything a content team pays for separately — optimization, briefs, claim review — in one deterministic engine that runs in your browser.→ Before reading, calculate how much dead content you produce per month
Five pillars withpublic weights: direct answer 25%, scannability 20%, citability 20%, demonstrable experience 20% and semantic depth 15%. The same article always producesthe same score— rules auditable line by line.
The engine's rule is concrete and measurable: aroughly 40-60 word passage with a verifiable data point, ready to compete for the citation. It's not "improve your structure": it's a rule that either passes or doesn't.
The ad promises, the article delivers. If they say different things, you pay for the click twice.No content optimizer can do this: we also built the ads one.
If your niche ishealth, finance or legal (YMYL), every unbacked figure and every hard promise gets flagged — the same anti-smoke layer as the Ads engine.
Articles organized by intent —BOFU, MOFU, TOFU— with a radar of terms your competition covers and you don't. Plus an audit of youralready-published article, by URL.
Our SEO won't let you pile up drafts faster than the search engine indexes them:the anti-mass philosophy is a product rule, not a sermon. AI rewrites with you; your experience — your own cases and numbers — is a requirement, not decoration.
The same audit in Spanish, English, Portuguese, French, German and Italian — preserving the direct answer, the citable passage and your experience. For teams with LATAM + US Hispanic audiences.
The same question answered two ways: the intro that writes "in today's digital world" vs. the one that answers first and brings citable data. Scores come from this page's engine.

Move the controls with your operation's numbers. The math is 100% yours: we don't insert improvement rates or promise rankings — we just make visible what you're already spending on articles the search engine never returns.
Deterministic calculation with your numbers:articles × % that doesn't rank × (hours × hourly cost + external cost). No improvement promises — the engine only tells you, before publishing, whether the article answers, reads well and gets cited.
