Full service agency vs specialist agencies: where social campaigns break

A full service agency runs every part of a campaign as one team, while specialist agencies each own one piece (video, paid ads, influencers, the landing page) and you connect them. Specialists can go deeper in a single channel; one full service team avoids the hand-offs where most campaigns lose money.

What a specialist agency stack looks like

A typical brand running social campaigns with specialists has four vendors. A creative studio or video shop makes the content. A paid social agency runs the ads, commonly priced at around 10% to 20% of monthly ad spend, often with a minimum fee. An influencer agency finds and manages creators. A web freelancer or dev shop builds the landing page.

Each one can be excellent at its job. But nobody in that list owns the whole path from scroll to sale. That job falls to you, usually a founder or a marketing lead who already has a full calendar.

Where campaigns break at the hand-offs

Creative made without ad data

The video shop delivers a polished set of ads. The ads agency learns in week one that the second hook wins, but the next round needs a new brief, a new quote and two weeks.

The ad and the page say different things

The ad promises a launch price; the landing page, built separately, leads with the brand story. Clicks arrive and bounce.

Nobody owns tracking

The ads agency assumes the developer installed the pixel events. The developer assumed the ads agency would. You find out after spending the budget.

Four reports, four definitions of success

Views from the video shop, ROAS from the ads agency, reach from the influencer agency, page speed from the developer. No single number tells you whether the campaign made money.

The blame loop

When sales are low, each vendor can point at another. The weakest step never gets fixed because no one is responsible for finding it.

The cost math: specialist stack vs full service

Take a brand spending $10,000 a month on paid social. At a 10% to 20% management fee, the ads agency alone costs $1,000 to $2,000 a month. At $20,000 in spend it is $2,000 to $4,000. That fee covers running ads, not making them, so you still need a creative retainer for fresh videos every month, creator fees and someone to build and update landing pages. Each vendor has its own minimum, and those minimums add up before the work does.

Our always-on campaigns start from $3,500 a month and include fresh creative every month, ad management, weekly testing and reporting, and posting. A one-off campaign launch starts from $5,000, landing page included. In both cases ad spend and creator fees are separate and paid directly. For a broader view of fee models, see how much a social media agency costs.

When specialist agencies are the right call

One team is not always the answer. Pick specialists when:

  • You spend heavily in one channel and need the deepest possible expertise there, such as a large paid search or paid social program
  • You run a creator program with dozens of creators every month and need a dedicated influencer operation
  • You have a strong in-house marketing lead whose job is to connect vendors and own the numbers
  • You only need one piece, for example ad management for creative your team already makes
  • A specialist already performs well for you; do not replace a working piece just to consolidate

How to test a full service agency's claims

Full service can mean a real integrated team or a sales layer over subcontractors. Ask:

  • Who makes the video, and who builds the landing page? The same team or outside vendors?
  • Can you show one report that goes from ad spend to revenue?
  • How long from spotting a losing ad to a new one being live?
  • Who sets up the pixel and conversion events, and who checks they fire?
  • Will we own the ad accounts, pages and creative files?
  • What is not included: ad spend, creator fees, extra rounds of creative?

Where Lumiflo fits

We are full service for one job: social campaigns that sell. One team does the creative strategy, video and UGC, paid social, creator work and the landing page and funnel, then tests and reports weekly. We started as a sales-funnel team, so the page behind the ads is part of the campaign, not an afterthought. The case study below shows what that looks like when the whole path from video to email to purchase is built together.

There is one gap most full service agencies leave open too. Growth agencies sell followers and stop there. Funnel agencies build pages and email sequences but need traffic the client doesn't have. Almost no one does both, works with creators, and ties its fee to sales. We grow the audience with organic content, build the funnel behind it, and offer a revenue share to creators and brands that fit.

Case study: a new product launch

We launched a new product. In 2 weeks, these are the results.

  1. 115kfollowers, starting from zero
  2. 7,000+emails collected
  3. 100+purchases across an app, a book and a paid community

No audience, no list and no sales on day one. Organic content earned the follow, a landing page captured the email, and three offers closed the sale. Read the case study.

Questions

What is the difference between a full service agency and a specialist agency?

A full service agency handles every part of a campaign as one team. A specialist agency does one part, such as paid ads, video or influencers, very deeply, and you coordinate it with your other vendors.

Is a full service agency more expensive than specialists?

Not usually once you add up the stack. A paid social agency alone commonly charges around 10% to 20% of ad spend before any creative or landing page work. Our always-on campaigns start from $3,500 a month with creative, ads and reporting included.

When should you hire specialist agencies instead?

When one channel is a very large share of your budget, when you run a big creator program, or when you have an in-house lead who connects vendors and owns the numbers.

Do full service agencies do everything well?

Not always. Some sell full service and subcontract the work. Ask who makes the video, who builds the landing page and whether one report covers ad spend to revenue.

Can I keep my current specialist and add a full service agency?

Yes. If a specialist is performing, keep them and agree clearly who owns what, especially tracking and the landing page.

How many agencies should a brand work with for social campaigns?

For most brands spending under a few tens of thousands a month on social, one team that owns creative, ads and the landing page is simpler and easier to hold accountable. Add a specialist when one channel grows large enough to need dedicated depth.
