Hi! I am SEO specialist at MjSeo. To solve your problem try to:
- Minimise HTTP requests.
Reduce and merge files.
Now that you know how many requests your site makes, you can start reducing that number. The best place to start is with HTML, CSS, and JavaScript files. - use asynchronous loading for CSS and JavaScript files.
- defer the loading of the JavaScript file.
Delaying a file means preventing it from loading until other elements are loaded. If you defer large files such as JavaScript, you ensure that the rest of your content can load without delay. - Minimise the time to the first byte
In addition to the amount of time it takes for your page to fully load, you'll also want to look at the amount of time it takes to start loading. - Reduce server response time.
- One of the most important factors affecting the loading speed of your page is the time it takes for DNS to look up the page.
- DNS, or Domain Name System, is a server with a database of IP addresses and associated host names. When a user enters a URL into their browser, a DNS server translates that URL into an IP address that points to their location on the network.
- Thus, DNS lookup is the process of finding a particular DNS record. You can think of it as your computer looking up a number in the phone book.
