    Tools to Analyze & Test the Page Loading Speed of Your Website

    Nowadays, Web search engines show millions of results for any keyword in 2 to 5 seconds and the visitors select any URL on a search engine result page (SERP) in next 10 seconds. After landing to your Website, any visitor takes only 5 to 8 seconds to analyze whether this page serves their purpose or not. If not then they close it and returns to the same SERP from where they came. In nutshell, you just have 5 seconds to attract the visitors to your Website, convert him/her into a reader and then into a potential buyer. Yes, Content is the King and Website design plays a great role in attracting the visitors. Still Page Loading Speed matters. Suppose your Website opens up slowly or take minutes to load its pages, then what will happen? The visitors will close the tab/window having your Website and this will turn into an increase in the bounce rates and thus traffic loss. Your Website should load immediately just after the pressing ENTER key or clicking the any link at the visitors’ browser irrespective of his/her connection speed, platform, and computer performance else you will lose a potential buyer. In this write up, we will highlight the tools to test the page loading speed of your Website. After testing with them, you can use their recommendations to improve performance.
