Entity coverage: Knowledge Graph lookup vs. NLP API

Entity coverage: Knowledge Graph lookup vs. NLP API
This week on the radar — proving your page covers the entities an update now rewards.

🔗 [Google's NLP demo / Entity API] — shows the entities and salience Google extracts from your text; closest to how it parses you.
🔗 [Knowledge Graph Search API] — confirms whether an entity you mention is one Google recognizes and how it's typed.
🔗 [SERP entity analysis of top pages] — reveals which entities the winners cover that you omit.

The tradeoff: the NLP API tells you what Google sees in your draft; the Knowledge Graph tells you what Google believes about the world; SERP analysis tells you the gap. Optimizing salience without checking competitor coverage means you can rank a well-understood page for the wrong entity set.
