HTML5 Test

About the test

The HTML5 test score is only an indication of how well your browser supports the upcoming HTML5 standard and related specifications. It does not try to test all of the new features offered by HTML5, nor does it try to test the functionality of each feature it does detect. Despite these shortcomings we hope that by quantifying the level of support users and web developers will get an idea of how hard the browser manufacturers work on improving their browsers and the web as a development platform. Please note that the HTML5 test is not affiliated with the W3C or the HTML5 working group.

Site Timer
Search Engine Viewer

"Site Timer" allows you to analyze some of the most critical aspects of "webpage performance". You can easily find out how long it takes for a dialup modem user to get your page, check all the graphical links to ensure they're correct, even take a look at your servers HTTP headers and more! Everything is done online, so you don't need to install or configure any special software, just click on the Site Timer link, enter the webpage URL, and away you go!

"Engine Viewer" is built off of the core of a search engine harvester (spider). What this means is you can view your webpage in the same way a search engine does, from how it breaks down the HTML, to which links it extracts, how it interprets your robot exclusion rules and more! Since a large percentage of most websites traffic comes from search engine results, it's now more important than ever to understand better how webpages are dissected and indexed.
