Traffic estimates are good for:
- PR campaigns
- Influencer marketing
- Sponsored content
- Social media marketing
- Display advertising or banner ads
Why are third-party traffic measurement tolls are limited by domain? Because it’s hard to predict how much traffic any particular page might receive on which your PR piece or ad might appear.
Web analytics tools (such as Google Analytics) can tell you how much traffic a particular page is getting. That’s not what these tools (above) provide. These measure pages from the outside, using these third party tools. That means any traffic metrics are estimated based upon sample sites.

Of course, quality websites tend to get a lot of traffic but these tools are measuring quality regardless of traffic. If you think about it: you could rank in the search engines for something nobody is searching for- this is quality without traffic.
