Benchmark page speed using meaningful metrics
First Meaningful Paint (FMP) is one of the more intuitive and useful performance metrics available, as it is user-centric. Defined to be 'when primary content appears on the page', FMP is essentially when it feels like the page has loaded (even if all the content has not yet been loaded in the background).
Utilizing its unique headless Chrome crawling environment, Sitebulb collects the Time to First Meaningful Paint for every URL, and also charts this data against web crawl depth, so you can see if certain page types (e.g. subcategory pages) or areas of the site (e.g. blog) are performing worse than others.
Time to First Byte (TTFB) is the amount of time it takes to receive the first byte of the web page from the server, and is considered a reasonable metric to gauge the performance of a website. To add an extra dimension to this data, Sitebulb also records the time taken to download all the HTML from the page.
Taken together, these metrics can give a good indication of the server performance, and can help identify latency issues.
