Top three things to fix

Turn on shape cleanup in your export tool, or drop the repeated points from shapes.txt.
Some route lines list the same point twice in a row. Repeated points don't hurt riders, but they can skew distance math and hint at a shaky export.
Effort: Usually one export setting.
Use mixed case for stop names and headsigns (e.g. 'Main St & 2nd Ave', not 'MAIN ST & 2ND AVE').
Some rider-facing names are in ALL CAPS or all lowercase. ALL-CAPS stop and headsign names are harder to read in apps and are read awkwardly by screen readers.
Effort: Often a bulk fix in your scheduling software.
Check the flagged column names for misspellings of standard GTFS fields; remove them if they are vendor extras.
Some files contain columns that are not part of the GTFS spec. Harmless to riders, but apps ignore these columns and they can hide typos in real column names.
Effort: A quick look at the flagged files.
