Do you know a slow website kills conversion? 47% of customers expect a website to load in two seconds at the very most. 40% will abandon it altogether if it takes longer than three.
So let's discuss what makes your website slow and we can fix it.
1. Unoptimized Image
- Check your image files that are above 1 MB is totally unacceptable.
- Use JPEG instead of PNG, especially for large images.
- Use the waterfall test to easily scan your site and suggest corrective actions.

2.JavaScript Issue.
- Audit your JavaScript scripts. So what is really needed and remove what you don't.
- Asynchronous loading is a must.
- Use Google Tag Manager or Segment. A single script for all your tools.
3.Too much flash content.
- Look for HTML5 replacements.
4. Excessive HTTP Requests.
- Use Sprites to reduce HTTP requests.
- Reduce the number of total files the user will have to download.
- Minify your CSS and JavaScript files.
5. Not making use of caching.
- You can cache CSS, and javascript files on client side and you can cache database queries on the server side.
Note: If you can cache something then do it. But do it carefully so you don't mess with something which can raise "cache invalidation" error.
6.Unclean code.
- Don't be lazy and use inline CSS when possible.
- Remove unwanted comments and lines from JavaScript and CSS files.
7. Files compression.
- Use G-Zip compression. It wraps all your files into a single container so the server response fast.
8.Too many ads.
- Ads requires additional HTTPS request so it increases the load time.
9. CDN
- Use CDS'N service. CDN helps to cache your whole website into various node servers available across the globe so your website loads fast.
- Examples: Cloudflare, Fastly, Akami, etc.
10.Hosting
- Choose the hosting carefully. Use Netflix or Vercel for static hosting
