From flat spend
to targeted
budget.

A travel startup's marketing budget, rebuilt from equal monthly instalments into a data-driven allocation model — using 18 months of booking and enquiry data.

At a
glance.

Five numbers that summarise the whole story — the rest of the page explains how they were achieved.

1,213bookings analysed across 18 months of data
31.58%average enquiry-to-booking conversion
268bookings for top destination (Turkey) — 2x the runner-up
67%of bookings made more than 121 days ahead
55% → 12%conversion swing between peak and low season

The "1,213" figure covers all bookings recorded between August 2023 and June 2025. The 31.58% conversion rate is calculated across all 16 months with enquiry data.

01 —
Executive
summary.

The client is a young travel startup operating for approximately two years, specialising in a narrow, well-defined customer segment. The existing marketing model allocated budget equally across every month — a flat spend that ignored seasonal demand patterns, destination performance, and customer behaviour.

I analysed 18 months of transactional and enquiry data to build an analytical pipeline that revealed how customers actually behave — which destinations they book, how far in advance they plan, which months convert best, and how age segments differ. The result is a data-driven allocation model that replaces guesswork with measurable evidence.

02 —
The
challenge.

The company had no substantiated view of audience behaviour, seasonal demand fluctuations, or the effectiveness of individual destinations. The marketing budget was distributed in equal monthly instalments — wasting resources during low-demand periods and failing to capture potential customers during peak decision windows.

Before — flat spend

The same budget every month, no regard for seasonality or destination performance.

Equal monthly spend, regardless of demand

After — data-driven allocation

Budget follows the data — concentrated where enquiries, conversion, and lead times justify investment.

Concentrated in peak enquiry + conversion months

The question: could 18 months of transactional and enquiry data reveal a spending pattern that actually matches customer behaviour?

03 —
Data &
methodology.

The study is based on 18 months of operational data from two internal sources: sales reports (transaction records, departure dates, prices, commissions, group sizes) and enquiry forms (submission dates, selected destinations, demographic data).

Raw collection
Cleaning
Anonymisation
SQL aggregation (Superset)
Visualisation (Tableau)

Data sources

  • Sales reports — transaction records, prices, commissions
  • Enquiry forms — submission dates, destinations, demographics

Privacy & confidentiality

Analysis was performed entirely on local AI infrastructure — no data was sent to external or commercial AI models. All personal identifiers were anonymised before processing. 100% data confidentiality was a core project goal.

Five analytical
blocks.

The dashboard was built around five analytical blocks, each answering a specific business question about marketing effectiveness and budget optimisation.

04.1 — Destinations

Turkey dominates with 268 bookings — more than 2x the runner-up Thailand (113). The top 3 destinations account for nearly half of all bookings, while the bottom 5 generate only around 10% combined.

Insight: Top 3 destinations account for ~48% of all bookings. Turkey alone generates 22%. The bottom 5 destinations combined generate only ~10% — marketing budget should follow the leaders.

04.2 — Booking window

This agency's clients are classic "planners" — 808 sales (67%) occur more than 121 days in advance. Last-minute bookings (0-7 days) represent just 0.25% of sales.

Customer
age.

Two groups dominate the customer base: 35-44 (89 people, 38.7%) and 45-54 (78 people, 33.9%), together forming approximately 70%. This is critical information for positioning marketing messaging and visual design.

Insight: Groups 35-44 and 45-54 form ~72% of the customer base. The ring sizes are proportional to group size — you can see at a glance that these two segments dominate. All marketing messaging and visuals should target this mature, financially stable audience.

04.4 —
Seasonality vs
conversion.

The enquiry-to-conversion relationship reveals a clear inverse pattern: when enquiries peak in summer, conversion drops. The highest enquiry volumes occur in February (80) and April (72), with conversion swinging from 55% in June down to 12% in August.

80 60 40 20 Jan Feb Mar Apr May Jun Jul Aug Sep Oct Nov Dec 12% 6% 73% CONVERSION %
Enquiry volume Conversion rate

Spring (Jan-Apr) is the optimal window for both volume and conversion (58-73%). Summer conversion drops from 55% (June) to 12% (August).

04.5 —
Destination
efficiency.

Conversion efficiency measures how many enquiries turn into actual bookings for each destination. A high score means every marketing euro spent returns bookings. A low score means you're paying for leads that never convert.

High Efficiency — Scale Up

Turkey

268 bookings · highest conversion rate

Every marketing euro invested in Turkey returns the most bookings. This is the destination to scale — increase budget, run retargeting campaigns, expand ad spend.

High Efficiency — Maintain

Thailand

113 bookings · strong lead-to-booking ratio

Converts leads consistently. Maintain current spend and optimize creative — the funnel works, just keep it warm.

Low Efficiency — Investigate

Egypt

74 bookings · lowest conversion rate

High enquiry interest but people don't book. Possible causes: pricing mismatch, weak landing page, or competitive pressure. Audit before investing more.

How to read this: High Efficiency = enquiries convert to bookings at a strong rate — invest more. Low Efficiency = enquiries arrive but don't convert — investigate and fix before scaling spend.

05 —
Business
impact.

Front-loaded budget

Campaigns concentrated in February-May, when both enquiry volume and conversion are highest.

Conversion-based allocation

Budget shifted from low-efficiency destinations (Egypt) to proven converters (Turkey, Thailand).

Segment-targeted messaging

Visuals and copywriting tailored to the dominant 35-54 age bracket — no wasted spend on mismatched audiences.

Full data confidentiality

All analysis performed on local infrastructure — zero data exposure to external services.

My
role.

Data Analysis · Business Intelligence · Marketing Strategy · Local AI Infrastructure

  • Collected and cleaned 18 months of operational data from two internal sources
  • Anonymised all personal identifiers before processing
  • Built SQL aggregation pipeline using Apache Superset
  • Designed and implemented Tableau visualisation dashboard
  • Analysed 5 analytical blocks: destinations, booking window, demographics, seasonality, efficiency
  • Identified seasonal patterns and conversion trends
  • Delivered data-driven budget allocation recommendations
  • Maintained full data confidentiality via local AI infrastructure
  • Presented findings and strategic recommendations to the client

What I
learned.

  • Volume is not value. A destination with many enquiries is not necessarily profitable — Egypt had high interest but the lowest conversion. Always measure efficiency, not just volume.
  • Long lead times change everything. 67% of bookings were made 121+ days in advance. This means marketing must start months before the season — last-minute campaigns are a waste of budget for this segment.
  • Interest does not equal efficiency. High enquiry counts do not guarantee bookings. The Egypt paradox — high interest, low conversion — showed that a destination can look popular on paper while failing to deliver returns.
  • Privacy is a design constraint. Running all analysis on local infrastructure was not optional — it was a core requirement. This shaped the entire approach: local SQL aggregation, local visualisation, no external data transfer.

Consultant
perspective.

How I would approach a similar data-driven marketing transformation:

  1. 01 — AuditMap current spend and existing data sources.
  2. 02 — CollectGather transactional and enquiry data from internal systems.
  3. 03 — Clean & anonymiseRemove technical noise, protect personal data.
  4. 04 — AnalyseRun SQL aggregation, identify patterns and inefficiencies.
  5. 05 — VisualiseBuild dashboards that make the data actionable for decision-makers.
  6. 06 — RecommendTranslate findings into concrete budget allocation decisions.

And this is where I work best — at the intersection of business needs and data-driven evidence.
