Data is the ‘Lab Data’ from Google – this is generated through simulated 3G connections to your site by Google.
Websites with lots of visitors may also see ‘field data’ in Google’s Page Speed Insights report, this is tracking actual visitors to your website who most likely are on faster connections than 3G so the data may be slightly different.
Not all websites have enough traffic to return field data so we use lab data for our report.
Data is collected weekly from Google’s Lighthouse platform using Legmark’s proprietary custom API. Scores can fluctuate based on a number of factors including:
- A/B tests or changes in ads being served
- Internet traffic routing changes
- Testing on different devices, such as a high-performance desktop and a low-performance laptop
- Antivirus software
All the data contained here should be used as a guide and in conjunction with other data sources to inform your strategy. Legmark is not responsible for the data or the impact of the data on your website performance.
