that is not reading. i dont think you can do so in 1 min. and if you can, there is no understanding of what you are reading. that makes it skimming through. personally, within 1 minute am able to tell you everything about a site and rate it. the other things that I can do will always take more than 1 minute
Depends on the website. If it is a good website, I can get a grasp of whatever page I am on in 1 minute. If a bad website, like a Turdpress site, the page won't even load in 1 minute, or if the website uses "partners.googleadservices.com" the website NEVER LOADS NO MATTER HOW LONG I WAIT.
Its amazing if you can read 500 words in a minute may be its a world record. I am not good at reading so one minute is not enough for me, i cannot optimized the web page in a minute.
