Title and description hygiene of the product catalog in the Google Merchant Center account linked to a GSC Wizard site: title length distribution (0-29 / 30-69 / 70-150 / 151+ characters), description length distribution (0-49 / 50-499 / 500-5000 / 5001+) and how many offers have no description, mean and median title length, duplicate titles (offers sharing the same normalised title, largest groups first), offers whose title repeats a word, and the most frequent title words with brand tokens flagged. Computed over a sample of the live catalog: the first limit products in feed order (default 2000, max 5000); truncated: true means the catalog had more. topWords[].share is a 0-1 FRACTION of the sampled offers, not the 0-100 ctr percentage; lengths are in characters, CJK titles included. A catalog snapshot, so it takes no date range. Returns a notConfigured result (not an error) when Merchant Center is not connected or no Merchant Center account is linked to the site in the GSC Wizard app.
