Text Analysis and SEO Optimization Guide
Whether you're a content creator, marketer, or copywriter, understanding how your text performs is essential. Our text and SEO tools help you analyse readability, keyword density, character count, and search engine preview — all in real time. Use these tools to refine your content before publishing and improve your chances of ranking well in search results.
Content Optimization Tips
- Aim for a Flesch readability score of 60-70 for general web content — this ensures most readers can understand your writing comfortably.
- Check keyword density to avoid keyword stuffing. A natural density of 1-2% for your primary keyword is usually sufficient.
- Always preview your SERP snippet before publishing. Titles should be under 60 characters, and meta descriptions under 155 characters to avoid truncation.
- Use the word counter to ensure your content meets minimum length requirements — longer, comprehensive articles tend to rank better for competitive keywords.
- Convert between text cases (UPPERCASE, lowercase, Title Case) to maintain consistent formatting across your content.

Frequently Asked Questions
How accurate are the readability scores?
Our tools use established formulas like Flesch-Kincaid, Gunning Fog, and Coleman-Liau. These are the same algorithms used by professional writing tools and provide reliable estimates of content readability.
Can I check SEO for languages other than English?
Word count, character count, and keyword density work for any language. However, readability scores like Flesch-Kincaid are calibrated for English and may not be accurate for other languages.
How often should I check keyword density?
Check during the editing phase, after your first draft. Focus on writing naturally first, then verify that your keyword usage is within a healthy range (1-3% for primary keywords).
