Digital marketing services, hired on evidence

Agencies with a verified published price

How to buy digital marketing services

1. Decompose the label before you shop. Name the channel that must work first for your business: local visibility, organic search, paid acquisition, or retention. That decision determines which specialists belong on the shortlist and prevents the classic failure of paying a full-service retainer for one channel's worth of attention spread thin across five.
2. Shortlist specialists over generalists, evidence permitting. The pattern across the verified index is that agencies are strongest where they specialise by channel or industry. An agency visibly succeeding at its own specialty, in its own market, is showing its ceiling; a generalist can match that only with equivalent published proof: named clients, readable work, checkable results.
3. Interview with Google's published hiring questions. Google's guidance for hiring search help generalises: examples and success stories, adherence to published guidelines, expected results and timeframe as realistic estimates, measurement method, industry experience. Its red flags generalise too: unsolicited pitches, secret methods, and guarantees, since no one can guarantee a #1 ranking.
4. Price each service against printed floors. A bundled full-service number cannot be compared with anything. Have finalists price each channel separately, then position those parts against the printed pricing agencies publish in this index. Bundles should be visibly cheaper than the sum of parts, or the bundle is the margin.

Full-service versus best-of-breed

One agency across all channels buys coordination: one roadmap, one report, one throat to choke, at the cost of depth wherever the agency is merely adequate. Specialists per channel buy depth at the cost of seams: attribution arguments, divided accountability and more management overhead. The evidence-led resolution is to let published proof decide per channel; hire the full-service shop only where its evidence is genuinely strong across every channel you need, which is rarer than the label suggests.

Whichever structure wins, the measurement standard is identical: results tied to enquiries, sales or pipeline rather than impressions and traffic, reported against the query and page data underneath. Google's starter guide sets honest timeline expectations for the organic side, hours to months depending on the change, and its helpful-content guidance defines the quality bar any content deliverable must clear.

Contract terms that protect the buyer

Ownership first: domain, website, content, ad accounts, analytics and data must belong to the business regardless of who operates them, in writing, before the first invoice. Agencies that run ads from their own accounts or hold content hostage at exit convert switching costs into retention, and unwinding that later costs more than any onboarding discount saved.

Then transparency: itemised monthly scope, direct access to every platform's native reporting rather than agency dashboards alone, and disclosure of markups on ad spend and of any affiliate or referral relationships, which FTC endorsement guidance requires to be disclosed when they shape recommendations. Month-to-month after an initial term keeps incentives aligned; long lock-ins are priced for the agency's benefit, not the buyer's.

Questions people actually ask

What do digital marketing services cost per month?

Printed retainers in the index run from hundreds of dollars monthly for single-channel local scopes into four and five figures for multi-channel engagements. Compare per-channel itemised quotes against published floors rather than bundled numbers.

Should I hire one agency for everything?

Only if its published evidence is strong in every channel you need. Otherwise hire the specialist for the channel that must work first and add others as each channel proves out; depth beats breadth when budgets are finite.

What results can an agency legitimately promise?

Method, effort and realistic estimates, never outcomes. Google states no one can guarantee a #1 ranking, and equivalent honesty applies across channels; a guarantee is a sales device, and Google's own hiring guidance treats it as a warning sign.

How do I verify an agency before the first call?

From its own pages: address, named team, printed pricing or floors, case detail naming clients, and visible success at its own specialty. Every agency in this index is listed on exactly that standard, and the check takes minutes on any candidate.
