Editor's Notes
- #2 I’m obsessed with making WordPress sites fast, and we’ll talk about why very soon. I also love memes… probably too much. All the memes in this presentation were found online, I didn’t create any custom memes for this. Obviously I’m not the only person who hates slow sites. Now who’s going crazy with this spinning loading wheel thing up here?
- #3 Disclaimer: this does not mean you can make any website load in 1 second or less. There are conditions, and I’ll talk about that later. But MOST WordPress sites should be able to load in 1 second or less, with some work.
- #4 I finally got off of DSL in 2010. Before DSL my parents had free internet from Juno (remember that?). But increasingly we live in a fiber world, and slow sites do not cut it anymore.
- #5 Averages Obviously 3G or 4G are going to be slower—we have to work with that though
- #6 I know, this is tough.
- #7 I’m not a ninja, but I’ve totally gotten up to make a sandwich before when something is taking a long time to load. Most users don’t want to work on ninja moves or sandwiches though—they just want to get to the information or tools they need.
- #8 In the SearchMetrics 2014 ranking factors study, site speed one of the most important on-page ranking factors. All other things being equal, the faster website wins.
- #9 How many of you have had this happen? If a website takes more than 5 seconds to load, I start thinking this.
- #10 Obviously speed matters for conversion. These studies go back years, and new ones keep cropping up.
- #12 If you don’t want to worry about speed for rankings, there are other very lucrative reasons to worry about site speed.
- #15 In the notes I’ll give out at the end, I’ve included my favorite hosts to use.
- #16 Your hosting platform needs to be commensurate with the load you will put on it.
- #17 Unless you have your own VPS or dedicated server, you won’t have options. But these things can help you ask questions to find a good web host.
- #18 Slow and steady never wins the race online. No philosophical arguments here.
- #19 PNG for graphics, jpg for pictures, only use gif for animations (SPARINGLY) Photoshop is THE BEST for optimizing images. A little trick in illustrator: turn your picture into a high-fidelity illustration, which reduces the number of colors, gradients, and shadows, thereby reducing file size. Then “Save for web.”
- #20 Tinypng is my favorite of these. Links in my notes at the end.
- #21 These install on your own server (VPS or dedicated), and allow you to create custom processes to reduce file size.
- #23 WP Smushit has no free option, but the other two do. I have tried all of these, though I haven’t tested extensively. In my experience, they all work well. Eventually I will run some extensive tests on these to see how they perform more exactly.
- #24 The BEST option. GIMP works OK, but not as well as Photoshop. Unfortunately. Adobe maintains its chokehold on the market (and my continued reliance on Windows).
- #25 Manual is the best. Period.
- #26 Mt. Timpanogos, creative commons license. Used as background behind some content on a WordPress site.
- #27 Can you tell?
- #28 Obviously I did a lot more than just compress one image, but this is to show you that crazy things can happen. And that 10-17 second load time was on a dedicated WordPress host… so yes, this stuff matters, and a properly configured server won’t always save you.
- #29 Not many people say this… but then older people or more likely to patiently wait for a page load than others.
- #30 If you’re not using a plugin, deactivate it and delete it. If you have inactive plugins installed but not used, and you don’t plan on using it any time soon, remove it (this won’t speed up your site, but it may help prevent security vulnerabilities from being exploited on out-of-date plugins). Optimize your database – this really means cleaning up all the auto-drafts, and other “garbage” that tends to pile up in WordPress databases. Use a light theme with a mobile theme switcher, or a mobile theme. Responsive is great, but sometimes it can’t get you to 1 second or less. There are always tradeoffs. I’ll talk more about javascript in a moment. This could be a presentation unto itself. There are tons of resource links in the notes about this page.
- #31 I’ll be selling ibuprofen after the presentation. :P
- #32 But wait, this real website is a successful business, and loads in 2 seconds with over 200 image files on that home page. What?!?
- #33 Caution: don’t combine your JS unless you really know what you’re doing, and be careful about minification. Some files won’t work properly if minified. Sometimes it’s a trial/error method to see what works and doesn’t. You are generally safe to combine and minify CSS, but keep on eye on it. HTML: please combine and minify.
- #34 These just cause the server to do extra work before it renders processes (CSS and JS particularly). There is a plugin for this to make it simple (in Notes).
- #35 This can be very complex, and depends entirely on your hosting plan and server configuration. As a general rule among WordPress plugins, my favorite plugin for caching is WP Rocket, but my favorite caching method is using the native cache within Nginx. WP Super Cache and WP Total Cache are also good alternatives, but if configured incorrectly can significantly slow down your site (instead of speeding it up).
- #37 Just don’t use Flash. ‘nuf said. As always, your 1 second is a budget. If you can justify a larger budget, or justify why you need JS and make up for speed in other areas, by all means. Just avoid using JS unjustifiably. Just because you can doesn’t always mean you should.
- #38 Not fast enough yet? We’ve still got a little work to do.
- #39 Tons of embedded video? This may cause you problems. YouTube’s embedded videos create a few HTTP requests per embed instance. If you have 10 videos, that’s 30+ HTTP requests, which definitely adds some load time. Embedded Twitter feed? Not only does nobody care, it slows down your site. Delete it. Gone. Google Fonts add some extra time to load your site. It’s miniscule (usually only a few milliseconds), but if you’re loading 3 different Google Fonts, now we’re talking 50 milliseconds. Look at your budget. If you’re using multiple ad networks, bless your heart. There really is no hope for you. Never hotlink from someone else’ site. Then you rely on their (possibly) slow server to load your image. Stupid. Plus you’re stealing bandwidth. Use a CDN.
- #41 This is a BIG issue. CSS has to fully load into the browser before it starts to render. Minification and combining the files helps, but you really need to make sure CSS is in the header. It should never be queued anywhere else. Ever. Period. Javascript should always be in the footer, unless it’s important to content rendering on the page, or is a tracking code and loads asynchronously. Otherwise, footer. Period. If you have tons of images (like lingscars.com), use the Lazy Load script so images load as a user scrolls down the page, rather than loading when the page loads. This reduces HTTP requests and load time significantly. Even if you only have 10 image files on your page, this makes a difference.
- #42 Faster now?
- #44 Thank you, thank you. Questions?
