Commodity content is content that repeats what many other pages already say without adding first-hand experience or knowledge no one else has. It may be technically accurate and well-written, but it is easily replaceable: a reader who saw the existing results gains nothing new from it.
The term became load-bearing in mid-2026 as generative AI lowered the cost of producing pages. When anyone can generate a competent article on any topic, generic coverage stops being scarce, and both search and AI engines raise the bar for what earns a place. Google guidance reported from an April 2026 Search Central event described leaving such pages in the "Crawled – currently not indexed" bucket: fetched, judged not useful enough, and not added to the index. Because AI Overviews and AI Mode draw only from that index, commodity content is invisible to them by extension, and other AI engines tend to skip it as a citation for the same reason.
The fix is not stylistic. It is to add what a commodity lacks: original data, testing, first-hand experience, and specifics that raise E-E-A-T and entity authority. Content that only rehashes is also prone to faster decay, since anything newer and more original displaces it.
