How to compare what you really pay

Work out the upfront payment

A low per-month figure can hide a large first payment. Pipiads at $24.50 per month means paying $294 today. Overview's weekly plan means paying €8.99, but four or more weeks cost more than one month at €25.

Read the usage limits

Cheap plans often limit what you can open. Pipiads charges 20 credits to view one ad's details, TrendTrack Starter allows 5 lookups per week, and Overview's AI advisor has its own credit allowance.

Check the platform you advertise on

Overview's research is built on Meta ads. If you sell through TikTok, a cheaper Meta tool is the wrong purchase at any price.

When Overview is not the cheapest choice

If you will pay for a full year, Dropispy and Pipiads cost less per month. If you only need to look up a known advertiser, the Meta Ad Library is free. If you need TikTok ads, look at Pipiads. We have not tested whether any of these tools has better data for your country, so try the same product in each one.
