The loading speed of a website depends on several factors, and each of them can be accelerated as far as possible.
Website page weight
The weight of HTML pages also affects loading speed – heavy pages with complex functionality and heavy media will take a long time to load. To make the page not so heavy, you can customize HTML elements with CSS, use media compression, configure caching, minify the page code.
You can read more about this in the article «How to reduce website weight and speed up page loading»: gzip, brotli, minification and other methods.
Redirects slow down speed – the server connects to one page, receives a redirect response, and navigates to another page. If your website contains many 301 redirects, check for traffic sources. In some cases, you might be better off replacing the redirect link to the destination page.
Redirects from HTTP to HTTPS can also slow down the process, in which case HSTS (HTTP Strict Transport Security) technology will help you. Then the browser will automatically make internal redirects, immediately make a request for HTTPS and redirect users to a secure connection. To do this, you need to enable the HSTS function in your hosting account or enter the HTTP Strict Transport Security header. But we advise you to test the function first to make sure all pages are accessible.
