Search engines seldom announce a penalty here — they just rank a less certain record lower. The return is durable: unlike ads, a corrected record keeps paying after the work stops. In other words, keep the description factual; the categories carry the relevance work.
Photograph or screenshot each profile before editing — reversions do happen. By and large, local directories weigh source quality as well as source count, therefore where a citation sits matters. Even therefore, a tidy citation profile makes every other local effort work harder.
