Which tool would you use to compare websites' traffic using third-party metrics?

• A. SEMRush
• B. Alexa
• C. AttentionMeter
• D. ABI/INFORM Global

Answer: (A)

To compare how much traffic different websites receive using third-party data, you want a tool that aggregates external traffic estimates and lets you benchmark domains side by side. SEMrush does this well by providing traffic analytics, estimated visits, top pages, and keyword performance for multiple sites. It’s designed for competitive analysis, so you can see how sites stack up against each other using data from third-party sources.

Alexa is another source of traffic data, but its strength lies more in rankings and audience insights rather than the broader, drill-down traffic comparisons SEMrush offers. AttentionMeter isn’t a standard tool for this purpose, and ABI/INFORM Global is an academic database, not a traffic analytics tool.
