The language decides how words and sentences are split, which stop words are filtered, and which readability formulas are valid.

How it works

How this is measured

Readability scores, but only the ones that were actually validated for the language you select. English gets Flesch Reading Ease, Flesch-Kincaid Grade, Gunning Fog, SMOG, Coleman-Liau and ARI; Polish gets FOG-PL; German, Dutch, French, Spanish and Italian each get the formula built for them.

Running an English formula on another language produces a number, not a measurement: Flesch Reading Ease reports a German children's book as very difficult, simply because German words are longer. For a language with no validated formula here, the tool reports the structural counts and LIX - a cross-language measure - and says that is what it is doing.

Below 100 words no score is shown at all, because every one of these formulas swings wildly on a single long sentence at that length. The structural measurements are still reported.

SSR vs CSR vs SSG vs ISR: what to choose for SEO and performance

SSR, CSR, SSG and ISR differ mainly in where and when HTML is generated. For SEO, the key question is whether important content and metadata are available without waiting for client-side JavaScript.

robots.txt and sitemap.xml: a complete technical SEO guide

robots.txt and sitemap.xml solve two different technical SEO problems. The first controls which URLs crawlers may fetch, while the second helps search engines discover important URLs and their metadata. Problems begin when robots.txt is used to block indexing or when a sitemap contains redirects, duplicates and noindex URLs. A solid setup combines crawl control, consistent canonical URLs, accurate sitemaps and Search Console monitoring.

Core Web Vitals in 2026: LCP, INP and CLS in practice

Core Web Vitals in 2026 still consist of three metrics: LCP for loading the main content, INP for interaction responsiveness and CLS for layout stability. The scores alone do not tell you what to fix. Effective optimization requires separating real-user field data from lab tests, finding the actual LCP element, slow interaction or layout shift source, and then monitoring the result after deployment.
