Paid placements are labeled Sponsored, and this category has none at the moment, so what you're browsing is the plain list, not a bought slot. If you run one of these agencies and your number or site link is out of date, you can claim the listing yourself and correct it so people searching for advertising help in Los Angeles reach the right desk. Call two or three that sit in your part of the city, check their sites, and start the conversation from there. This page won't rank or recommend any one shop for you.
