The essentials
- The answer: both, at two different levels. A consolidated dashboard to decide (leadership, budget), channel views to optimise (team, agencies).
- A single dashboard alone: readable but too thin for optimisation; it forces you back into each platform.
- By channel alone: precise but incomparable; every channel proves it deserves more budget, nobody sees the whole.
- 2026 costs: a two-level architecture costs €1,500 to €5,000 to build in Looker Studio or Power BI, or €40 to €200 per month on an integrated platform.
Centralising or separating dashboards is a question every decision-maker faces as soon as the channels multiply: SEO, Google Ads, social media, email, GEO. A single dashboard promises an overview; channel dashboards promise precision. This article compares the two approaches, describes the cases where each one fits and proposes the two-level architecture that reconciles them. Building a consolidated view in practice is detailed in creating a multichannel dashboard, and the readability principles in creating a clear dashboard for a leadership team.
The single dashboard: what it brings and what it cannot do
| Advantages | Limits |
|---|---|
| An overview: results, cost per result and each channel's share side by side | Not enough depth to optimise a campaign or a page |
| A neutral source for comparing channels (GA4, CRM) | Each platform measures differently; consolidation requires conventions |
| A common language for leadership, marketing and agencies | A single dashboard that tries to show everything becomes unreadable |
| Visible synergies (a social campaign that lifts brand searches) | Maintenance: every API or connector change breaks a source |
| One target per metric, one definition | Update lag tied to the slowest connector |
Channel dashboards: what they bring and what they cost
| Advantages | Limits |
|---|---|
| The platform's precision: search terms, creatives, placements, frequency | Each channel counts its conversions its own way; the sum exceeds reality by 30 to 80% |
| Immediate update, in the native tool | No comparison possible between channels |
| Suited to campaign managers and agencies | Every channel proves it deserves more budget |
| Free (native reports from Google Ads, Meta, Search Console) | Leadership receives five reports instead of one answer |
| No connector maintenance | Synergies between channels are invisible |
The cases where each is enough
- A single active channel: a very small business doing only Google Ads or only SEO has no need for consolidation; the native report and a summary page are enough.
- One agency per channel, with no internal steering: the channel dashboards are supplied by each agency, but the budget cannot be arbitrated; this is a situation to move on from.
- A leadership team that only wants an answer: a single dashboard of five to seven metrics is enough for leadership, provided the team keeps its detailed views elsewhere.
- Two channels or more, with a budget to arbitrate: the general case for small businesses in 2026, which makes consolidation necessary.
The two-level architecture
- Level 1, the consolidated view: a leadership page (5 to 7 result metrics with targets), a “channels” page (full spend, results from a neutral source, cost per result, each channel's share, trend), a measurement page (data reliability). Source: GA4 or the CRM for the results, the platforms for the spend. Read monthly, arbitrated quarterly.
- Level 2, the channel views: one page per channel with its optimisation metrics (SEO and GEO, SEA, social, email, site), in the same tool if the connectors exist, or in the platforms' native reports otherwise. Read weekly by the team and the agencies.
- The link between the two: same definitions, same UTM conventions, same periods; a gap at level 1 is understood at level 2. The glossary is shared.
- Alerts: on level 1 for leadership (results, costs), on level 2 for the team (spend, frequency, tag failure).
This architecture answers both needs without mixing them: leadership reads one page, the team optimises in detail, and the budget is arbitrated on comparable figures. The metrics to keep per channel are listed in the KPIs to measure by advertising channel.
2026 tools and costs
| Option | Level 1 (consolidated) | Level 2 (per channel) | 2026 cost |
|---|---|---|---|
| Looker Studio with connectors | Yes, with third-party connectors for Meta, LinkedIn, CRM | Yes, pages per channel | €1,500 to €4,000 to build, €50 to €300 per month for connectors and maintenance |
| Power BI or Tableau | Yes, with modelling | Yes | €3,000 to €10,000, internal skills required |
| Integrated marketing platform | Yes, native | Yes, channel views included | €40 to €200 per month, little building |
| Native reports plus a spreadsheet | Manual, monthly | Platform reports | Internal time, frequent errors |
The tool comparison is in the tools for creating a marketing dashboard, and the neighbouring question of centralising tools in all-in-one marketing tool: centralise or not.
The frequent mistakes
- A consolidated view that shows everything: 40 charts on one page; level 1 sticks to the results and the costs per result.
- Consolidating the platforms' conversions: adding up Google, Meta and LinkedIn conversions gives a false total; the neutral source is mandatory.
- Different definitions between levels: a conversion rate calculated on sessions at level 1 and on clicks at level 2 makes the gaps incomprehensible.
- An abandoned level 2: leadership reads the consolidated view, nobody optimises; results decline.
- One dashboard per agency: each with their own, with their own definitions; consolidation belongs to the company.

Frequently asked questions
Do you need a single marketing dashboard or one per channel?
Both, at different levels: a consolidated dashboard of a few pages to decide (leadership, budget arbitration, results from a neutral source) and channel views to optimise (team, agencies, metrics specific to each platform). Both share the same definitions.
Why not just use each platform's reports?
Because each platform counts its conversions its own way and their sum exceeds reality by 30 to 80%; no comparison between channels is possible, every channel proves it deserves more budget, and leadership receives five reports instead of one answer.
What does the consolidated dashboard contain?
A leadership page with 5 to 7 result metrics and their targets, a channels page with full spend, results from a neutral source, cost per result, each channel's share and trend, and a measurement page on data reliability. It is read monthly and serves the quarterly arbitration.
What does a two-level architecture cost in 2026?
From €1,500 to €4,000 to build in Looker Studio with third-party connectors, then €50 to €300 per month for connectors and maintenance; €3,000 to €10,000 with Power BI; €40 to €200 per month on an integrated marketing platform with no build.
Where do you start when you have nothing?
With a five-column channels page (channel, full spend, results from a neutral source, cost per result, trend), fed each month, even by hand. It is enough to arbitrate the budget; the connectors, the channel views and the alerts are added once it has proved its usefulness.
