Comparison of the search and citation mechanics of ChatGPT and Claude: search rates, year-number injection, domain overlap (8%), UGC share.
Year-number injection is the rule in our data for product, price, news and comparison questions, not for local and entity questions. The share is therefore above Blyskal's 17%, which may be down to the topic mix.
