Five Tools to Measure Website Response Times
Digital media types - from website owners to online marketing managers and designers - should understand the importance of having a website that responds quickly, where webpages load fast and in their entirety. When consumers wait too long, they risk alienating their users and aggravating the search engines. So how do you know if your website's response time is too slow? Use one the following five services for a quick glimpse into this important technical metrics.
Google Analytics: It's more than a digital destination to keep track of unique visitors and page views, Google Analytics also offers some useful details on website load times. GA provides the average page load time, the average server response time, and more, including how page load times vary by browser, by country/territory, even down to the page.
Pingdom Website Speed Test: A free tool from Pingdom, just enter a URL to see how long it takes for a website to load, as well as the waterfall (when elements load, from CSS to scripts, and what specific item may be the cause of the delay). Pingdom's tool also provides a general "performance grade" along with some general page speed recommendations, a page analysis report measuring load time, size and requests.
WebPageTest: Not nearly as visually appealing, but every bit as detailed (if not more so), WebPageTest shows the load time and the first and a repeat view, how long it takes for the page to start rendering, and even tracks when the document is fully loaded.
Internet Supervision: Perhaps the most straightforward of the tools suggested here to measure website response times, and from multiple locations around the world (unlike the other services listed here), Internet Supervision provides a no-frills look at how long it takes for a website to fully load.
GTmetrix: One of the more robust tools to measure site response times and performance, GTmetric provides a detailed breakdown of page speed, offering up recommendations to improve performance, and a timeline/waterfall look at the potential hangups, culminating in a page speed grade, which can be used to improve a site.
