数据 API / DataForSEO / On Page
Keyword Density
Word and phrase frequency across a crawl, with keyword_length choosing n-gram size. Returns total_items_count, items_count and items. Reads a finished crawl, so it needs the id from post_dataforseo_on_page_submit and returns crawl_progress plus a crawl_status of max_crawl_pages, pages_in_queue and pages_crawled - check those before trusting a small result, because a crawl still running simply has less to report. This describes what a site says about itself; for what the web says about it use post_dataforseo_backlinks_anchors_live, and for what people search use post_dataforseo_keywords_gads_search_volume_live. 💰 Free upstream: querying a finished crawl costs nothing, only the crawl itself does.
