As brands look for measurable market share, they cannot continue to use fragmentation within vendor relationships to develop disconnected messages, fragmented data and lost revenue.
This guide will help you understand the various operating models, pricing models and verified performance evidence from the leading integrated marketing agencies built to centralize your marketing strategy.
The Modern Integrated Marketing Agency Landscape
Finding a single full-service agency partner is not a simple task. Clients prefer to reduce the headache of managing multiple vendors, e.g. SEO, paid media, creative vendors and so forth, and want one accountable vendor to manage all of their media/advertising strategies.
However, the agency marketplace is full of competing firms that offer "one-stop-shop" capabilities. Many also use nearly identical language to promote near-identical products (data-driven, cross-channel success) without making clear the ways in which their operations support those claims.
A complete integrated system does not imply just offering several services through one company. The significant difference is how an integrated marketing agency connects those services. True integration occurs when an agency develops a single shared strategic brief that is used by all its departments.
Your campaign planning, audience modeling, and measurement definitions would all come from a single centralized source. If the public relations team does not have shared commercial KPIs with the paid media buyers, then the agency is simply a collection of silos. A buyer's decision must be based on evidence when separating types of agencies.
In addition to verifying the respective agencies' outcomes, understanding their pricing structures and requesting proof of each agency's capabilities, it is essential to consider how an agency ties together data, technology, and creative execution as a means to support pipeline growth.

How to Evaluate Integrated Marketing Agencies
To properly evaluate the capabilities of an integrated marketing agency, be cautious of relying solely on numbers. Credible case studies should detail the entire process from start to finish, what time period the project occurred, what media was used, and who the target audiences were.
It is important to differentiate between incremental results and agencies taking credit for simply leveraging existing brand search volumes. Price is not the first indicator of capability; understanding the level of integration that can be achieved per fee level is more useful.
A low retainer is likely to provide access to only very few channels, whereas a high project fee usually provides only for the creative launch and does not include paid media, SEO, CRM management, and/or conversion rate optimization.
Agencies must each itemize their financials digitally and include items related to the following: strategy, creativity and production. Each media spend must be separated from the agency's fee. In the event that the relationship ends, be sure to clarify who owns the assets, data and ad accounts. Agencies with the strongest capabilities should demonstrate the correlation between marketing metrics and real CRM outcomes through the use of first-party data and a process called marketing mix modelling (MMM).
The 90-Day Transition Plan
Transitioning from a group of different vendors to one unified vendor will significantly change how you do business. The real problem for the person searching for a vendor, in most cases, is how to coordinate among all the different vendors.

You will likely have too many handoffs as well as competing campaign priorities and fragmented reporting among vendors. Having a structured onboarding process ensures that the vendor's objectives align with the client's commercial objectives before funds are spent.
30 Days After Engagement: The agency must conduct an audit of the client's existing channels, analytics, CRM configuration, and creative assets, confirm the client's audience positioning and provide strict definitions of KPIs and identify any gaps in tracking for the client's campaign objectives.
30-60 Days After Engagement: The agency will begin building the campaign's centralized architecture. The agency will identify each channel's role in the campaign, video, display etc., create reusable content modules and build dashboards to track pipeline metrics, as well as clicks.
60-90 Days After Engagement: This period is for execution. The agency will commence implementation of multifaceted and coordinated campaign launch efforts, conduct landing page tests, and conduct an initial evaluation of incoming leads from the new campaign. Total re-allocation of the budget continues based on factual evidence and revenue feedback as they come in.
Final Thoughts on Vendor Consolidation
The integration of marketing is not about how many services an agency provides, but rather how the agency’s strategic function, creative function, media channels, data management and commercial measurement integrate and function together as one system.
The current landscape is rife with directories that offer up global networks side-by-side with small boutique shops. Therefore, you need to look beyond a label such as "full-service" when selecting integrated marketing agencies and instead force the agency to explain how its team works in an integrated manner.
You must understand whether or not all the specialist functions are working together under one accountable lead and if they can validate their value to you through running incrementality tests. The strongest partners will have an established process for taking a single strategy and evolving it across all the various touch points to maintain brand integrity and operational efficiency with your spend.
Common Questions About Making the Switch
How do you measure success when combining channels?
To measure incrementality when consolidating channels under one roof, it is critical to have a clear understanding of how the agency will set the baseline for their metric identification process. Without this baseline, the agency may take credit for a single sale from multiple channels (paid social, organic search, emails) and the risk of duplicate attribution increases.
To prevent this, you must require the agency to define their baseline before commencing with campaign activity. Use a combination of both holdout groups and marketing mix modelling to identify the true incremental lift. You need to ensure the agency will prove that all of its collective efforts will create new revenues that would not have occurred but for its involvement in the process.
What is the most common failure point in the first 60 days?
The single largest bottleneck during the first 60 days of integration is always a lack of access and alignment between the tracking capabilities or platforms being utilized. Agencies frequently build a complex set of campaign architectures based on media channels only to find that the client’s CRM tracking is either messy or broken at the server level.
If the agency is not able to provide a clear path or line of sight back to the first click through closed deal in the CRM, then the model is destined to fail. It is critical to identify all critical tracking gaps prior to the launching of any new media within the first two weeks of the integration project.
Should media spending remain separate from the main management fee?
You should always keep your media spending separate from your agency's management costs and your creative production costs. Bundling media spending in with your agency management costs creates a conflict of interest and therefore hides the true cost of delivery for you.
You want total transparency regarding how much money goes to the media channels, and how much money the agency charges to manage the media spending you are allocating to it.
If we decide to terminate our agreement with the agency, who owns the data and accounts?
This must be articulated in your contract from the outset of your agreement with the agency. Many agencies will use their proprietary accounts to build campaigns, and therefore the loss of the campaign history, audience lists and ad performance history upon termination will occur.
You must require that all of your ad accounts, analytics properties, and CRM integrations be owned by you at all times and that your agency is given access as an administrator.
