Track down-to-the-millisecond speed metrics for your users, see how speed affects your conversion rate, and get alerts & reports to stay on top of it
Not everyone sees the same loading times for your site. People on faster devices and connections will have a better experience than others. Blackbird measures highly accurate speed metrics for your actual visitors, so you get the true picture.
Blackbird automatically tracks the Core Web Vitals for your real users over time, so you can make sure you're delivering not just a fast site, but a great user experience.
You've always heard that faster visits convert better, but now you can see it with your own data. Blackbird tracks the difference in conversion rates between your faster and slower visits, and tells you when the data is statistically valid.
Faster than average mobile visits are 39% more likely to convert, with a conversation rate of 3.62% vs 2.43% Data is statistically significant
