WEBVTT 1 00:00:00.000 --> 00:00:03.924 Crawlability, indexation, and ranking are three separate diagnostic layers. 2 00:00:03.924 --> 00:00:08.284 First ask whether a search engine can fetch the page. 3 00:00:08.284 --> 00:00:12.208 Check status codes, robots rules, links, rendering, and logs. 4 00:00:12.208 --> 00:00:17.876 If fetching works, ask whether the engine kept the page in its index. 5 00:00:17.876 --> 00:00:21.365 Check canonicals, duplicates, soft errors, and page value. 6 00:00:21.365 --> 00:00:27.033 Only after both layers pass should you investigate relevance, authority, intent, and competition. 7 00:00:27.033 --> 00:00:30.085 Fixing titles cannot solve a blocked crawl. 8 00:00:30.085 --> 00:00:33.137 Resubmitting cannot make a weak duplicate rank. 9 00:00:33.137 --> 00:00:34.445 Diagnose in order.
