Content Clarity Suite – Write Cleaner, Rank-Ready Content

We review a lot of small business content as part of our SEO work (service page copy, blog posts, homepage descriptions) and the same problems come up repeatedly: sentences that are too long, passive voice that buries the offer, keyword usage that’s either absent or stuffed, and heading structures that are either missing or incoherent. The Content Clarity Suite combines the checks we run manually into one tool, with bilingual readability scoring for our Spanish-language clients.

What each tab checks

Stats: word count, character count, sentence count, paragraph count, and estimated reading time. Also calculates average words per sentence, average syllables per word, percentage of complex words, and readability scores in both English (Flesch Reading Ease) and Spanish (Szigriszt-Pazos).

Sentence heat map: color-codes your text by sentence length. Short sentences (under 15 words) appear in green; medium sentences (15-24 words) in yellow; long sentences (25+ words) in red. Scan it visually to find where your writing gets dense and hard to follow, no reading required.

Passive voice: flags sentences matching common passive voice patterns (“was written,” “is known,” “has been reviewed”). Passive voice isn’t always wrong, but it tends to bury the subject and weaken service page copy particularly. Aim for under 20% passive sentences on persuasive pages.

Keyword density: enter a target keyword and see how many times it appears and at what density percentage. Target range: 0.5%-3% of total words. Below 0.5% is undersaturation (the page may not send a clear topical signal). Above 3% starts to look like keyword stuffing. Neither extreme is helpful.

Headings: extracts and displays your heading structure from markdown (# H1, ## H2) or ALL CAPS lines. Use this tab to verify the logical hierarchy before publishing, H1 → H2 → H3, no skipped levels, headings that actually describe the section content.

SERP preview: enter a title tag and meta description and see how they’ll look in a Google search result, with live character counts and color indicators for under/over the recommended length.

Bilingual readability: Flesch and Szigriszt-Pazos

The Flesch Reading Ease formula was built for English and doesn’t translate accurately to Spanish — different average word lengths and syllable patterns make the English score meaningless when applied to Spanish text. The Szigriszt-Pazos formula is the validated Spanish equivalent, calibrated specifically for Spanish phoneme patterns.

Both scales run 0–100. Higher scores = easier to read. Target 50–70 for general web content in either language. Below 30 is academic/legal difficulty. Above 80 is elementary reading level.

This is the only free readability tool we know of that handles both languages in the same interface.

FAQ

• What Flesch Reading Ease score should my web content target? For general web content (service pages, blog posts, landing pages) target between 50 and 70. Scores in the 60-70 range are considered “standard” and appropriate for a general adult audience. Below 30 is very difficult (academic journals, legal contracts). Above 80 is very easy (children’s content). Most effective small business web copy scores between 55 and 65.
• Does keyword density still matter for SEO in 2025? Yes, but not as a mechanical target. Google’s algorithms are sophisticated enough to recognize topical relevance from context, synonyms, and related concepts, not just raw keyword repetition. The density check in this tool is a diagnostic: if your target keyword appears 0 times on a 1,200-word service page, that’s a problem. If it appears 25 times, that’s also a problem. The 0.5%-3% range is a reasonable guardrail, not an optimization target to chase.
• What is the Szigriszt-Pazos readability formula? The Szigriszt-Pazos formula (also called INFLESZ in some implementations) is the primary validated readability formula for Spanish-language text. It was developed in Spain in the 1990s and uses syllable counts and sentence lengths calibrated to Spanish phonology. The scale runs 0-100 like Flesch, with higher scores meaning easier text. It’s the formula used in Spanish academic publishing and healthcare communication standards.
• How accurate is the passive voice detection? The tool uses pattern matching against common passive constructions (“was [past participle],” “is being [past participle],” “has been [past participle]”). This catches the majority of passive voice patterns in English but produces some false positives (phrases like “is known for” or “was meant to” that aren’t passive in the grammatical sense). Use the highlights as a guide for sentences to review, not a definitive count.
• Can I use this tool to check my meta description length? Yes, go to the SERP Preview tab, paste your title tag and meta description, and see the live character count alongside a preview of how it renders in a Google search result. The character count updates live with color coding: green for ideal length, yellow for borderline, red for over the recommended maximum.
