NLP content auditing uses advanced natural language processing to analyse how search engines understand your pages. Get insights into entity recognition, topical coverage, semantic relationships and content optimisation opportunities, all from a single URL-based brief.
Create a brief from any URL on your domain and see your content performance score within minutes.
Create a brief from any URL on your domain, select a lead or custom query and target market, and we run a complete NLP audit. See entities Google recognises, topical depth, readability and how your content compares against the pages currently ranking.
Once a brief is processed, view a comprehensive overview including content scores, SERP orientation, user intent classification, readability, search engine understanding metrics, topic analysis and detailed entity research, all in one place.

Real NLP analysis, built from how search engines actually parse your pages.
Most content tools score keyword density. NLP auditing goes further: it identifies the entities, topics and semantic relationships Google extracts from your content, scores how salient each one is, and surfaces gaps between your page and the ones currently ranking. No keyword-stuffing checks, no surface-level grading - the actual signals search engines use to understand what your content is about.
This data feeds directly into content briefs, rewrites, internal linking and schema strategy.
Run an NLP audit on your URL and the pages currently ranking for your target query, side by side. SEO Stack surfaces the entities and topics your competitors cover in depth that your content barely mentions, or misses entirely.
Salience scores show you which entities Google considers important for the query, so you know which gaps actually move the needle and which are noise.
Pair that with readability, SERP orientation and user intent scoring and you have a clear, prioritised optimisation list.
Close the gaps that matter, not the ones a keyword density check tells you to.
