How We Calculate Traffic Rankings
Methodology
SimilarWeb data inputs
Direct measurement
Contributory network
Partner data
Public sources
Multi-source signals are modeled to estimate visits.
Modeling & QA
SimilarWeb blends observed signals with statistical models and machine learning to estimate monthly visits.
We use the latest available month.
What we do on this page
We roll up regional domains into one company view and focus on standalone car-rental OTAs only.
No suppliers, aggregators, or multi‑product companies.
Domain Rollup
Regional and localized domains are merged into a single broker footprint so the share reflects true brand demand.
Standalone OTAs
We list car-rental comparison OTAs, not suppliers or multi‑product travel giants, to keep the comparison fair.
Why SimilarWeb
SimilarWeb is a widely used benchmark and publishes its methodology; it cites a SparkToro study showing estimates closest to Google Analytics among major providers.
Traffic on this page is based on SimilarWeb’s monthly visit estimates. The data combines direct measurement, contributory panel signals, partner data, and public sources, then models them into a single visit figure.
We consolidate all regional domains into one company view. That makes the market share comparable across global brands that operate multiple country sites.
The list is limited to standalone car-rental OTAs. We exclude suppliers, aggregators, and multi‑product companies so the ranking reflects pure car‑rental demand.

Traffic FAQ
FAQ
How should I read market share vs month-over-month change?
Market share shows who is biggest today, while month-over-month change shows short-term momentum. Use both together.
Why can traffic drop but rankings stay similar?
When the whole category slows down, many brokers decline at the same time, so relative positions can stay stable.
Does higher traffic mean better booking quality?
Not by itself. Traffic reflects demand; combine it with Reviews and Suppliers pages for a fuller quality picture.
How often is traffic data refreshed?
We refresh when a new monthly dataset is available and publish updates on our regular cycle.
