❓ Your questions

Everything about Content Sentiment Analyzer

What exactly does the Content Sentiment Analyzer measure?+

It measures emotional polarity (positive/negative/neutral), specific emotion intensities (joy, anger, sadness, fear, surprise), and readability indexes (Flesch-Kincaid, Coleman-Liau). It also highlights sentences by sentiment color, enabling instant copy optimization.

Is it completely free? Are there any hidden limits?+

Yes, SEOScaleUp’s sentiment analyzer is 100% free with no registration. You can analyze unlimited URLs or text samples, and we never ask for credit card info. Core features like emotion scoring, bulk compare, and exports remain free.

Can I use it for non-English content?+

Absolutely. Our NLP model supports 190+ languages, including Spanish, German, French, Chinese, Arabic, and Hindi, with localized sentiment detection trained on cultural nuances.

How accurate is the sentiment detection compared to human review?+

Our model achieves 89-94% agreement with human annotators on benchmark datasets (SST-5, GoEmotions). For marketing/SEO content, it’s highly reliable for polarity shifts, but we recommend pairing with your domain expertise.

Does it store my data or text?+

No. All text is processed in real-time via encrypted requests and never persisted. We don’t train models on user data, and no logs retain your content after analysis.

Can I analyze a whole website or sitemap?+

Yes, use the bulk mode: upload a CSV of URLs or paste up to 20 links at once. You'll receive a consolidated sentiment report with average polarity per page.

What formats can I export?+

Export results as CSV, JSON, or PDF with visual sentiment charts. Ideal for client reports or internal content audits.

How often is the sentiment model updated?+

We retrain quarterly using new linguistic corpora and social media trends to stay accurate for modern slang and internet culture.
