Marketing
Full-service and specialist marketing agencies — strategy, campaigns, digital execution, and analytics — the index’s second-largest category at 550 US firms.
The wall
The marketing wall is rarely a lack of activity — it is activity without compounding. Campaigns run, content ships, budgets get spent, and the pipeline stays flat. Companies hit it when the generalist who ran marketing at $2M cannot orchestrate the specialist channels required at $10M, or when a first agency delivered deliverables instead of outcomes.
What the discipline is
The Marketing category holds full-service and multi-channel agencies: firms that own strategy and execution across several channels at once — positioning, campaigns, paid media, email, web, and analytics — rather than specializing in a single discipline. Single-discipline specialists live in their own pillars (SEO, Content Marketing, Social Media Marketing, Creative Strategy).
How vendors in this category work
Most firms here sell monthly retainers scoped to a channel mix, with project pricing for defined builds like a website or a rebrand. Across the index's engagement data, the most common hourly band among US agencies is $150–$199, the most common minimum project size is $5,000, and the typical firm runs a 10–49 person team — useful baselines for judging any specific quote.

Questions buyers ask
Questions sourced from live Google "People Also Ask" data for this discipline (harvested August 2026); answers are The Wall's own.
What does a marketing agency do?
A marketing agency plans and executes the work that attracts and converts customers: strategy and positioning, campaign planning, paid and organic channel execution, creative production, and performance measurement. Full-service firms own several of these at once; specialist firms go deep on one.
Is it worth using a marketing agency?
It is worth it when three things are true: the product already sells (an agency amplifies what works — it cannot invent product-market fit), the budget can sustain a real engagement for at least a quarter or two, and the internal team lacks the time or specialist skill the channel requires. When any of those is false, fixing that first outperforms hiring anyone.
How do marketing agencies make money?
Four models dominate: monthly retainers for ongoing scope, fixed project fees for defined deliverables, a percentage of managed ad spend (commonly 10–20%), and performance pricing tied to leads or revenue. Retainers remain the default for ongoing multi-channel work; ad-spend percentage is standard where paid media is the core service.
How do I choose a marketing agency?
Define the outcome first, then filter structurally: specialty match, engagement data (rate band, minimum, team size), and evidence of work on companies your size. In conversations, weight the firms that diagnose before prescribing. Ratings will not narrow the field — across this index, category average ratings all sit between 4.88 and 4.94 — so structured facts and fit questions do the real filtering.
How many marketing agencies are there in the US?
Counts vary with the definition: industry trackers estimate roughly 41,000 dedicated marketing firms, and well over 100,000 businesses when advertising and digital agencies are included. The Wall’s Marketing category deliberately lists a vetted 550 — US-based, verified live, and structured for comparison — rather than attempting an exhaustive census.
