Now we’re going to chat about how keeping an eye on site performance can really make a difference.

Keeping Track of Performance

Starting any improvement without knowing where you stand feels like diving into a pool without checking the water level. Spoiler alert: It can end poorly!

Missing the monitoring step can lead to confusion. It’s like trying to find a needle in a haystack—most of the time, you have no clue if your efforts are making a dent.

So, let’s follow a simple principle:

Improve, then measure.

One nifty tool to keep an eye on your site is Google Lighthouse. Think of it as a fitness tracker for your website—keeping tabs on how it runs and where it might need a little jumpstart.

Believe us, tracking these metrics can feel like watching paint dry at times, but it’s crucial. After all, would you drive a car without a dashboard? Not unless you're feeling adventurous!

For a more hands-on approach, there’s a helpful article discussing how to use a Google Sheet for performance tracking. It's like keeping a diary of your site’s progress. Who doesn’t love a good before-and-after story?

Day by day, you’ll see the numbers—like watching your favorite team score—keeping the excitement going as you see your site's speed improve.

If you crave variety, consider using PageSpeed Insights or WebPageTest.org. They can also be your trusted companions on this quest for a swift-running site. Isn’t it nice to have options?

Google Lighthouse: Your website's fitness tracker.
Google Sheets: The personal diary of performance.
PageSpeed Insights: A classic for monitoring speed.
WebPageTest.org: For those who love to test under various conditions.

With our monitoring systems in place, we can finally roll up our sleeves and get into the improvements. It’s like prepping for a big feast; you want to know what has worked before you whip out the secret family recipe!

Now we’re going to chat about optimizing images on a site. You know, those beautiful snapshots that can either make your website shine like a diamond or like a rock thrown into a pond. Images can really weigh down a page, but fear not! We have tricks up our sleeves. Let’s dive in!

Optimizing Images for Better Performance

First off, there’s no denying it: images are often the heavyweight champions of website performance issues. It’s like inviting a sumo wrestler to a sprint; things might get stuck!

Did you know images can account for over 60% of a page's total weight? Just like that extra slice of cake at a party—you thought you could handle it, but then you’re the one on the couch, groaning.

Compression is Key

Impact: High

Why Compress?

Imagine a beach ball of a photo getting squished into a neat little baggie! That’s what compression does—reducing file sizes without sacrificing quality.

If you’ve ever taken a photo with a fancy camera, you know it can be as large as your Aunt Edna’s holiday fruitcake. With perceptive compression, we can chop that size down by up to 90%! Who wouldn’t want a little magic like that?

How to Check

To check if compression is in order, fire up your Dev Tools and peek into the network tab. Filter by “Img” to see file sizes; if they’re larger than 100kb, it’s time to compress that doughy image.

Compression Rules of Thumb

If JPEG >100kb, smash it down into another JPEG.
If you have a non-transparent PNG, it’s time for a JPEG makeover.
Transparent PNG? Go for WebP and have an optimized PNG waiting in the wings.

A terrific tool for this is Squoosh. It's like having a personal chef for your images; watch those sizes shrink!

Crop Those Offenders

Impact: Medium

Why Cropping?

We’ve all seen a photo of a square image served up in a rectangle—why waste precious pixels? Let’s keep it tight and right, folks!

Rectangles download heavier, and that’s just not necessary. Save yourself the hassle!

Look for Differences

Scan your site for images that don’t match their display ratios. A CSS clue could be lurking in your styles!

Cropping with Tools

Using Squoosh’s resize tool can help maintain glorious proportions while trimming the fat.

Ditch the Metadata

Impact: Low

Metadata Madness

Every time you capture a lovely moment, that photo carries a bunch of unwanted background info—camera specs, location glam shots, you name it. Bye-bye unnecessary weight!

Checking Metadata

Use an online tool like Metapicz to unveil hidden metadata. Just drop in the image URL.

Tools that Help

Many compression tools, including Squoosh, will kick out that metadata automatically as they work their magic.

Lazy Loading is a Must

Impact: High

Why Lazy Load?

No one likes to wait, right? Loading images only as they scroll into view allows the initial page to zip right along. It’s like uninvited guests arriving at staggered times instead of all at once!

How to Check

Clear the network tab in Dev Tools and start scrolling. If you see images pop up—ding, ding, ding! You have lazy loading!

Implementing It

The easiest way to do this is through the native lazy loading attribute on images. Just add it like this:

<img src="cat.jpg" loading="lazy" alt="Cool Cat!">

Although Chrome started supporting this in 2019, more browsers will follow. If needed, check out various JavaScript fixes.

Responsive Images are Essential

Impact: Low

Why Go Responsive?

With all kinds of devices buzzing around, catering to their varying sizes is smart. Nobody wants a pixelated image on a gorgeous retina display! Let’s keep things sharp!

Identifying Responsive Needs

Check for picture tags in the HTML and search for “srcset” to spot different versions of the same image.

Using Picture Tags

Utilize the <picture> tag to cater to mobile, tablet, and desktop:

<picture>   <source media="(max-width: 799px)" srcset="cat-480w.jpg">   <source media="(min-width: 800px)" srcset="cat-800w.jpg">   <img src="cat-800w.jpg" alt="A Cat"> </picture>

Go Vector or Go Home

Impact: Low

Why Choose Vector Graphics?

Vectors are a dream; they scale without losing clarity. Think of them as the stretchy pants of images—perfect for any occasion!

Check for Vector Graphics

Explore your network tab and see if you can swap any images for SVGs—perfect for logos and graphics. Non-photos like screenshots are still out of the picture.

Creating Vectors

You can easily save most vector graphics as SVG. Just remember server-side compression to keep those files lightweight!

Now we are going to talk about optimizing HTML. It’s like giving your code a fresh haircut—clean, tidy, and ready to impress!

Optimizing Your HTML for a Snappier Experience

Minify the HTML

Impact: Medium

Why

How

Here’s a nifty trick for fonts: <link rel="prefetch" href="/assets/fonts/font.woff2">

Action	Impact	Steps
Minify HTML	Medium	Use an HTML minifier
Remove Boolean Attributes	Low	Search and remove in Dev Tools
Remove Comments	Low	Use HTML minifier to erase comments
Remove Legacy Attributes	Low	Identify and delete via Dev Tools
Minify Inline CSS & JS	Medium	Use minifier with correct options
Load CSS Before JavaScript	High	Reorder scripts in your HTML
Limit iFrames	High	Evaluate necessity of iFrames
Use Pre-fetch	Low	Implement prefetching for assets

Now we are going to talk about making your web applications run smoother with some practical tips on JavaScript. Think of it as giving your site a little fitness makeover—no sweat required!

JavaScript Enhancements That Matter

The JavaScript scene is bustling! With frameworks like React and Vue showing off their moves, it’s hard not to feel a bit left behind if we're not on our game.

We need to keep our JavaScript files lean, mean performance machines. After all, nobody enjoys waiting endlessly for a website to load—it’s like watching paint dry, but less exciting!

Let’s break it down with some practical strategies.

Trimming the Fat: Minifying JavaScript

Impact: Medium

Why Bother?

Just like we wouldn’t want a bulky suitcase when heading to the beach, we don’t want bloated JavaScript files either! Minification reduces file size without messing with functionality. It’s like squeezing a squash into a suitcase—efficient packing!

What’s Involved?

Dev Tools are our best pals here. Check the network tab to see if the JavaScript files have been packed down nice and tight—fewer comments and indents are what we want!

Making It Happen

Ever seen a site that loads jQuery straight from the main site without a .min? That's like ordering a large pizza when you only need a slice. The original jQuery file weighs in at 273KB, but the minified version is just 93KB. Talk about a weight loss plan!

The original jQuery file: 273KB.
The minified version: 93KB.

So, always double-check to ensure that our trusty site is using the minified version. If not, UglifyJS can work wonders!

Let’s Get Async!

Impact: Medium

Why Go Async?

When we drop a <script> tag in the middle of the page, it’s like hitting the pause button on a dance floor. All fun stops as the browser scrambles to fetch that file! We really don’t want that. So, let's avoid blocking our party!

The magic words here are async and defer. They allow the scripts to do their own thing without halting the show.

Inspecting HTML Files

async or defer? If not, it’s time for a little sprinkle of optimization!

Choosing Between Async and Defer

If a script needs to load like an eager puppy, go with async. If it needs to wait for a friend to finish first (like jQuery), then defer is the way to go.

Who Needs Bloated Frameworks?

Impact: Medium

Why Avoid Them?

Frameworks can become like that one friend who just brings too much to the picnic—unnecessary and a bit of a hassle! Developers are now hustling to create lighter, faster alternatives.

Finding Alternatives

Look into what frameworks are being used on your site. A quick research session might uncover some snappier options.

A Quick Switch

If you’re using jQuery, consider shifting to Cash—it’s compact and efficient!

Stay Updated

Impact: Low

Why Update?

Using three-year-old technology is like wearing yesterday's fashion—nobody wants to be caught in outdated gear! Keeping third-party frameworks updated helps with speed and security.

Checking Versions

Browse through all the third-party JavaScript files in use—there might be new releases waiting to be adopted!

Finding the Latest and Greatest

Hit up NPM to see the latest versions to ensure you’re not stuck in the past!

Now we are going to talk about CSS maintenance—a topic as beloved as a rainy day for a picnic. Just the other day, while tweaking a website, we stumbled upon a CSS file longer than a Sunday novel. It's amazing how CSS files can accumulate like holiday decorations in the attic, isn't it? Let's explore why a little housekeeping can do wonders.

CSS Maintenance

Over time, our CSS files can balloon unexpectedly, leaving us wondering whether our classes are still relevant.

Reviewing our CSS isn’t just wise; it’s necessary—like wearing matching socks! So, let’s tackle how to keep it in check.

Minify the CSS

Impact: Medium

Why Minify?

Just like we squish down a sleeping bag to make it fit, we can shrink our CSS too. Every byte counts, especially in today’s fast-paced web browsing scenario. Remember how your mom would say, "Every penny counts"? Same applies here folks!

What’s Involved?

To check for minified CSS, we can use Dev Tools. Open up the network tab, and check for CSS files—easy peasy lemon squeezy!

How to Do It

If you happen upon a CSS file that resembles a messy teenager's bedroom, it’s time to use an online tool like CSSNano to clean it up. Trust us; it’s like a breath of fresh air!

Identify Unused CSS

Impact: Low

Why Bother?

What to Look For

Determining what’s in use can feel like trying to find a needle in a haystack. The good news? Lighthouse Audit can do the heavy lifting for us!

How to Remove It

Online, we can use UnCSS. Load up your HTML and CSS, and it'll show the styles that need to hit the road. Just keep in mind; some styles may make a surprise appearance later.

Critical CSS for Above the Fold

Impact: Medium

Why It Matters

By loading only the essential CSS for what users see without scrolling, we make our site snappier. It’s like serving appetizers while the main course cooks!

What’s Needed?

Check your HTML. If there are inline styles happy in the head, ensure they cater to the upper part of your page. It sets the stage for first impressions!

How to Implement

Run it through UnCSS by selecting your above-the-fold HTML. After that, just insert this snazzy CSS inline in your head. Voilà!

Employ Preload

Impact: Medium

Why Preload?

Once we’ve managed above-the-fold CSS, we still need the rest without causing hiccups. It’s like having dessert ready while the main dish is served!

What to Check

Look for any `` tags in your HTML with preload enabled. This is key for a smooth ride!

How to Do It

Change your code from just a stylesheet link to a preload link. It’s a simple twist that keeps the rendering from hitting a traffic jam!

Clean Up Inline CSS

Impact: Low

Why Clean Up?

While inline CSS has a place for critical above-the-fold styles, the rest? Out the door! We can lighten our HTML for a speed boost.

What to Look For

Check under the Network tab for any rogue inline CSS that just won’t quit.

How to Proceed

Save your extracted CSS as a new file, and replace those inline styles with a shiny external link. It’s like upgrading from a flip phone to a smartphone!

Now we are going to explore how fonts play a crucial role in web development and why we need to keep them in check to avoid a slow-loading site.

Optimizing Font Usage

Fonts are like the icing on a cake—necessary for that final touch, but too much icing can leave a bad taste. We’ve all been there: waiting for a page to load, then BAM! It feels like we’re stuck in a 90s dial-up nightmare. To keep our users happy, let’s ensure our font choices don’t bog things down.

Embrace WOFF2

Impact: Medium

Why Choose WOFF2?

According to Google's research, WOFF2 packs 30% more compression than its predecessor, WOFF. That means more time spent reading and less time watching those spinning loading wheels. So, let's jump on that bandwagon and make sure we’re using WOFF2!

How to Check Font Formats

Type 'Inspector' in your browser. No, not for reality TV; we’re talking about the Network tab. Look for font files and check their extensions—simple as pie! (Just try not to eat the pie while you work.)

Handling Browser Compatibility

Some browsers haven’t caught up to WOFF2 yet, so we need to have backup options. When in doubt, falling back to WOFF or TTF is our best bet. To make this happen, we can use the following CSS snippet:

@font-face {   font-family: 'MyWebFont';   src: url('webfont.woff2') format('woff2'),        url('webfont.woff') format('woff'),        url('webfont.ttf') format('truetype'); }

Then we can incorporate it into our styles like so:

body {   font-family: 'MyWebFont', Fallback, sans-serif; }

Pre-Connect—The Secret Sauce

Impact: Low

Why Use Pre-Connect?

Sometimes we source fonts from different servers, which can lead to delays while the browser gets its bearings. Well, we can speed things up by preparing that connection ahead of time! It’s like setting a date before actually meeting—just good planning.

Finding Pre-Connect Links

Head over to the "Elements" tab and keep your eyes peeled for any <link> tags related to font domains. This is a little like hunting for treasure—except the only gold here is faster load times!

Setting Up Pre-Connect

Ready to make that connection? Insert this code into your page’s head:

<link rel="preconnect" href="https://fonts.gstatic.com" crossorigin>

Don’t forget to customize the URL for your fonts. It’s not a one-size-fits-all deal!

Next, we’re going to explore some simple changes that can really speed up how a server communicates with our browsers. Think of the server like a waiter at a restaurant: if they’re slow, the food takes forever to come out, right? Let’s make sure our server is a top-notch waiter!

Server Speed Optimization

One of our best friends in this speed race is TTFB, or Time To First Byte. It tells us how quickly the server serves up the first byte of the requested file.

We’re aiming for a TTFB under 1.3 seconds—like a cheetah on espresso!

To check this, hop over to the network tab and click on the HTML file. Find the timing tab, and voila! If it reads under 1.3 seconds on a Fast 3G connection, you’re golden. If not, let’s discuss some fixes.

Compression Efficiency

Impact: High

Why Compress?

Enabling compression on your server is like cramming your suitcase so you can take more stuff on vacation—fewer data bits mean quicker loads.

The server zips up files before sending them over. This makes them smaller while they travel. Who doesn’t love that?

What to Look For

To see if compression’s working, check out the content-encoding header in the Network tab. If you spot gzip or br, congratulations! Your files are being compressed.

How to Enable Compression

Turning on compression is like adding a bit of seasoning: it varies by server setup. Here are some resources:

But a friendly tip: only compress text files. Raster images get cranky about that and may slow down instead!

Consider compressing these file types:

HTML
CSS
JavaScript
SVG
JSON
XML

Caching Strategies

Impact: Medium

Why Cache?

The quickest files to load are already cached. Telling browsers to cache assets is like having a stocked fridge; no need to run to the store every time!

Cached assets allow the browser to check the date on the asset, known as the expiry. If it’s still fresh, the fridge stays closed!

What to Control

To set this up, we use the cache-control HTTP header. You can see this in the network tab.

How to Set Caching Rules

When configuring caching, keep these rules in mind:

Cache images for a year—save them for the great pasta dinner of 2024!
Cache CSS and JavaScript for a month—perfect for seasonal changes.
Do not cache HTML—it’s like leaving food out overnight; nobody wants that!

Next, we are going to talk about some practical strategies to enhance your website's efficiency and speed.
