When a page does not show up in search as expected, debugging means finding out why. Sometimes the page renders differently for a crawler than for a person. Other times a script hides content, or a tag has a mistake in it.
Most of these videos come from Google's own channels, and the newest is a talk from a technical SEO conference. Anyone fairly new could start with Hunting a heinous hreflang headache, a story from 2022 in which Bastian Grimm traces a fault on a shop site. Martin Splitt of Google goes through diagnosing JavaScript problems in Debugging JavaScript SEO issues, a short session from 2020. Developers can go on to Rendering, Style, and Layout When Things Go Wrong, from 2025. The 2019 Chrome Dev Summit talk on Googlebot is the oldest here, so check its steps against current documentation.
