How can I find out which elements are making my website slow? Any suggestions?
You can use Google's Pagespeed Insights tool to analyze your site's speed and It will show the data on what elements are reducing the site speed and why. After that, you can evaluate things based on your site platform and hosting and can sort out this site speed issue.
Try this out and let me know!
You can check your website loading speed using the Pingdom speed test tool. The result will tell what elements of a webpage are heavy, fast, slow, too big, and so on. The tool will also give you solutions to any particular slow loading issues. I will personally suggest Pingdom to check sites' slow loading warnings & errors.
GTmetrix is likely the best tool available for analyzing page speed. It offers a report on the speed at which your website loads, as well as PageSpeed and YSlow scores and other page information. It also enables you to set up alarms, check your load time, and assess how well your website performs in comparison to other websites. There are free and premium versions of GTmetrix.
Site speed, which is the page speed for a representative sample of page views on a site, is frequently mistaken for page speed. Page speed can be measured in terms of page load time which measures how long it takes for a page to fully show its content (how long it takes for your browser to receive the first byte of information from the webserver).
Below are some tools for measuring page load times.
