Why it matters to a buyer
A page being crawled is not the same as it being indexed, and the gap between the two is where a lot of buyer confusion sits: Search Console will show a page as "crawled, currently not indexed," which is not an error message so much as Google deciding the page was not worth adding to its index yet, often because it looked thin or duplicative. For a buyer, understanding this stage explains why fixing a technical crawl issue does not always fix visibility on its own.
How it is measured or applied
After crawling, Google renders the page, evaluates its content and quality signals, and decides whether to add it to the index and under which canonical URL. Indexing is requested, not guaranteed, through submitting an XML sitemap and using Search Console's URL inspection tool to ask for a recrawl, but Google indexes at its own judgment and pace. Status is checked page by page in Search Console's URL inspection report, and in aggregate through the page indexing report, which groups all non-indexed URLs by the reason Google gives for excluding them.
