`add_keywords`Adds keywords to an app's tracked set in one storefront. Takes a list or a comma-separated paste. They arrive unscored - scoring costs requests to Apple and happens on the collector's schedule - so do not read a null popularity here as a zero.

`ranking_keywords`Which keywords an app is already ranking for, from the pooled record of every search this product has run.

Apple publishes no endpoint for this; the answer is only as wide as what has been observed, so an app nobody has swept near returns little.
