Advertising and marketing services, compared for buyers

Agencies with a verified published price

How to buy advertising and marketing services without guessing

1. Write down the outcome before you read any proposal. One sentence: what has to be true in twelve months for this to have been worth it. More qualified enquiries, a lower cost per booked job, entry into a new region, a rebrand that stops confusing buyers. Agencies will happily shape a proposal around a vague brief, and you will then be comparing two different jobs against each other.
2. Split the work into media, creative and strategy. Media is money that leaves your account and goes to a platform. Creative is production of the things that run. Strategy is thinking, research and planning that produces neither directly. Ask each candidate to price the three separately, because bundling them into one monthly figure is what makes proposals impossible to compare and margins impossible to see.
3. Ask exactly how the firm is paid. A flat retainer, an hourly rate, a percentage of media spend, a commission from a platform or publisher, or some combination. Each creates a different incentive, and a percentage of spend rewards spending more. None of them is wrong, but a firm that will not answer plainly is telling you something. Get it in the contract alongside what happens when spend rises.
4. Check who is actually doing the work. Ask which services are delivered in house, which are subcontracted, and who your day to day contact will be once the people who pitched you have moved on. Then ask to meet that person. A large share of full service proposals are assembled from freelancers, which is fine when disclosed and expensive when discovered late.

What the label actually covers

Advertising is the paid part: search and social ads, display, video, out of home, radio, print, and the buying and planning that puts money behind them. Marketing services is everything else a firm might sell around that, from positioning and messaging through website work, content, email, search visibility and public relations. Some firms genuinely deliver most of this under one roof. Many resell the parts they do not do, and the honest ones say so when asked directly.

For a buyer, the practical consequence is that the first meeting should be spent narrowing, not exploring. Decide which two or three services you are actually buying this year, then ask each candidate to price those and only those. A proposal that expands to cover everything is easy to sell and almost impossible to hold anyone accountable for, because no single line in it owns the result.

What we record about the agencies here

Our index records what each firm publishes about itself, with the date we checked: stated service lines, published starting prices where they exist, disclosed minimum engagements, and named clients. Where a firm publishes nothing on price, we record that absence rather than estimating, because a made up figure would make the comparison worse rather than better.

Full service firms publish price less often than specialists do, which is a structural fact about how they sell rather than a mark against them. It does mean that building a shortlist in this category usually requires you to ask for the minimum engagement directly. It is a single email, and the replies will thin the list considerably.

Claims, disclosures and the things a good firm raises first

Advertising that reaches consumers carries legal obligations that fall on the advertiser as well as the agency. The Federal Trade Commission publishes guidance for businesses on advertising and marketing, covering substantiation of claims, endorsements and testimonials, and disclosures in social content. A candidate who raises substantiation and disclosure unprompted, before you ask, is a candidate who has been through it before.

Ask any firm proposing influencer or creator work how disclosures will be handled and who approves them, and ask any firm proposing comparative claims what evidence they expect you to hold. These questions cost nothing and reveal a great deal about whether the shop has adult supervision or is optimising for the version of the ad that performs best in a preview deck.

Questions people actually ask

Is a full service agency better than hiring specialists?

It is simpler, not automatically better. One firm means one contact, one invoice and consistent messaging. Specialists usually go deeper in their discipline and are easier to replace individually. The deciding factor is normally whether you have someone internally who can coordinate three suppliers. If you do not, a single accountable firm is worth the premium.

Should the agency hold our ad accounts?

Set them up under your own billing and grant the agency access. Your data and your spend history stay yours, you can see actual spend against actual results at any time, and a change of supplier becomes an access change rather than a rebuild. Reputable firms agree to this readily. Resistance is the answer to a different question.

How much should we hold back for creative production?

Enough that the money you spend on media has something worth running behind it. Buyers routinely allocate almost everything to placement and then wonder why performance is flat. Ask each candidate what proportion of the budget they would put into production for your category and why, and compare the reasoning rather than the number.

What is a reasonable first commitment?

Long enough to produce evidence and short enough to leave if it does not. For paid media that is often one quarter, since data accumulates quickly. For brand or search work it is longer, because nothing meaningful is visible in a month. Ask for a break clause tied to agreed reporting rather than a discount for signing a year.
