Deciding what to change
Re-running consumes an entitlement per product, so it is worth knowing what to change first. Re-running the same products with the same inputs and the same data produces much the same output.
Let the scores narrow it first
Which factor scored low points at which input to fix: accuracy at your source data, consistency at the record or the batch mix, brand adherence at your guidelines. See Understanding quality scores.
That narrows the question. The next step is deciding which of the two levers to pull.
Which lever is short?
Two things determine output. Read a weak result and decide which one failed.
Source data sets what there is to say. If the output is accurate but empty — correct sentences carrying no information — the record had nothing in it. No amount of input tuning fixes that.
Inputs set how it is said. If the output is substantive but sounds wrong — off-tone, generic, using words you avoid — the facts were there and the instructions were not specific enough.
What costs what
This shapes the order of operations: edit what is nearly right, and re-run only after changing something that will produce a different result.
Re-running with new inputs
You can repeat an enrichment on the same products with revised brand voice and context. Change one thing at a time where you can — revising guidelines, keywords, and context simultaneously tells you the output improved without telling you why.
Test on a smaller batch
Before re-running 250 products, re-run 25 with the revised inputs. If the change worked, apply it to the rest. If not, you have spent 25 entitlements learning that rather than 250.
