A customer tells you your website "takes forever" on their phone. You open it on office Wi-Fi and it looks fine. Then you try it on mobile data in the market and watch a blank screen for a while.
Website speed optimization is the work of finding what makes a page heavy and removing it. Some of the fixes need no developer at all. This post is the fix list: what you can do yourself this week, what needs a developer, and how to check the work before you pay.
Quick answer
What is website speed optimization?
Website speed optimization means making your pages load and react faster for real visitors, mostly by sending less data and asking the phone to do less work. It covers images, scripts, fonts, hosting and the order in which things load.
Google measures the result with three scores called Core Web Vitals. We explain those scores in a separate guide. Here we stay on the fixes.
Why "it is fast on my computer" does not count
Your office computer is powerful and your Wi-Fi is strong. Your customers often use a mid-range phone on mobile data. Google's PageSpeed documentation says its lab test runs on one simulated device and network, while the real-user data comes from actual Chrome visitors on many devices.
So always test on the Mobile tab, and always try your own site on mobile data, away from Wi-Fi.
How do you find what is slowing your site?
Run your main pages through PageSpeed Insights and read the list under the score. It names the slow parts in plain labels, such as images that are too big, or scripts from other companies. Fix the items with the biggest estimated savings first.
- Open PageSpeed Insights and enter your home page address.
- Choose the Mobile tab and note the performance score. 90 or above is good, 50 to 89 needs improvement, below 50 is poor.
- Scroll to the suggestions and diagnostics. Write down every item that mentions images, third-party code, redirects or server response time.
- Repeat for your two or three most visited pages, such as a product page or the page your ads point to.
- Save screenshots. You will compare them after the fixes.
How to increase website speed: fixes you can do yourself
You can do four useful things without touching code. Upload smaller photos, remove add-ons you do not use, point every link to your final address, and use fewer fonts. These cost nothing but time, and they often fix the biggest items in the report.
1. Upload photos at the size they are shown
A photo straight from a phone camera is far bigger than any spot on a web page. Chrome's Lighthouse guide says a page should never send an image larger than the size shown on the screen, because the extra bytes only slow the page.
Before uploading, resize the photo to roughly the width it will appear at. If your website editor offers WebP or AVIF, use it. Google's guide says these formats load faster and use less mobile data than JPEG or PNG.
2. Remove add-ons you do not use
Chat bubbles, popups, review widgets, social feeds and old tracking codes all add scripts (small programs that run in the visitor's browser). Google's web.dev guide on third-party code says: if a script does not add clear value to your site, remove it.
Make a list of every add-on on your site and who asked for it. You will often find a tracking code from an agency you stopped paying years ago.
3. Make links point to your final address
Each redirect is an extra trip across the network, and Google's Lighthouse guide says this can add hundreds of milliseconds. A link to the old "http" address may bounce twice before reaching your real page.
Here is a tip most owners miss. Check the website link on your Google Business Profile, your Instagram bio, your WhatsApp Business profile and your ads. Use the exact final address that shows in the browser bar.
4. Use fewer fonts
Every font style (regular, bold, italic) is often a separate file the phone must download. Ask your designer to keep to one or two font families and only the weights the design really uses.
Website performance optimization: fixes that need a developer
The deeper fixes live on the server and in the code. They include compressing files, letting browsers remember files, loading scripts in a smarter order, and better hosting. You cannot do these from a normal website editor, but you should know what they are so you can check the work.
| Fix | What it does in plain words | Official guidance |
| Lazy loading for lower images | Images further down load only when the visitor scrolls near them | Never lazy-load images visible at the top, especially the main banner |
| Text compression (Brotli or GZIP) | Squeezes page files before sending them, like a zip file | Lighthouse prefers Brotli, with GZIP as backup |
| Browser caching | Lets a returning visitor's phone reuse files it already has | Files with version numbers in their names can be cached for a year |
| Script loading order | Makes chat and tracking scripts wait so the page shows first | Use async or defer for third-party scripts |
| Click-to-load embeds | Shows a still picture of a YouTube video or chat box; the real one loads on click | Lighthouse calls this a facade |
| Better hosting or a CDN | Your server answers faster; a CDN keeps copies of your site closer to visitors | web.dev says most sites should aim for a server response of 0.8 seconds or less |
If your report shows most of these problems at once, the old site may cost more to patch than to rebuild. In that case, compare a quote for fixes with a quote for The Beyond Horizon's website development service for Indian businesses before you decide.
The lazy loading mistake to watch for
Some speed plugins and developers switch on lazy loading for every image. Google's web.dev guide warns against lazy loading images that are visible when the page first opens. If the banner photo at the top is lazy loaded, it can show up later than before.
Should you fix your current site or rebuild it?
Fix it if the problems are mostly images, extra add-ons and hosting. Consider a rebuild if an old theme or page builder loads heavy code on every page. That is clear when the report still shows heavy scripts after you remove the add-ons.
We do not publish a price list for speed work, because the cost depends on a few things you can check yourself.
What changes the cost of speed work
Questions to ask before you pay
- Which pages will you test, and will you show me the Mobile results before and after?
- Which add-ons will you remove or delay, and will any feature stop working?
- Will you change my hosting, and who will hold the hosting login afterwards?
- How will you make sure the top banner image is not lazy loaded?
Closing note
Start your website speed optimization with the free steps: test on mobile, shrink your photos, remove add-ons you do not use, and fix your links. Then bring the PageSpeed report to a developer and ask for the fixes in the table.
