Speeding up a WordPress site involves optimizing images, using a content delivery network (CDN) to improve load times, selecting fast hosting, and implementing caching. Page speed is important for user experience and retention - users leave sites that take over 4 seconds to load. Optimizing images reduces file sizes while maintaining quality. A CDN stores content on globally distributed servers to deliver pages faster. Caching saves page content for quick retrieval to improve load times.

1. Speed up Your WordPress Site

2. Agenda
- Understand the ‘Page Speed’ Term
- Why faster?
- Run The Speed Test Properly
- Speed Up Your WordPress Site

3. Understand the ‘Page Speed’ Term
The length of time at which web page is downloaded from hosting
servers and displayed onto the web browser.

4. Why faster?
- 1 in 4 (25%) visitors abandon the website if it takes more than 4 seconds to load.
- 46% of users don’t revisit poorly performing websites.
- Website owners have a mere 5 seconds to engage visitors before they leave.
- 74 % of users accessing the mobile site would leave if it takes longer than 5
seconds to load.
- Every one-second delay in page load time could lead to $1.6 billion in annual
losses for online merchants as big as Amazon.
- SEO benefits, more profit, more downloads, and the list goes..

5. Run The Speed Test Properly
1. Enable and configure Caching.
2. Enable and configure CDN.
3. Choose the test location. It has to be close to your hosting server.
4. Test multiple times!

7. Speed Up Your WordPress Site
• WordPress website types
• Hosting
• DNS: Free vs Premium
• Image Optimization
• CDN or/and Offload Media
• Themes and Plugins
• WordPress Tweaks
• Caching
• Optimize Mobile First

8. WordPress Websites Types
Static / Small
- Blog
- Business Portfolio
- Personal
The content does not change very
often. Content can be served from
cache.
Dynamic / Large
- eCommerce (WC,EDD)
- Membership
- LMS
Content is changing frequently.
Can’t be served from Cache and
server resources are needed.

9. Hosting
- Shared Hosting
- DIY VPS
- Managed Hosting
-- PHP 7 (or the latest)
-- NGiNX
-- HTTP/2
-- Server Location

10. Hosting - Shared Hosting
- Starts from less than $3 per month. (Renewal is different!)
- Crowded servers -> Slowness
(GoDaddy, BlueHost, HostGator)
YOU GET WHAT YOU PAY FOR!

11. Hosting - DIY VPS
- Do everything yourself
- Starts from $5
- Perfect for people who know what they’re doing.
(Digital Ocean, Vultr)

12. Hosting - Managed Hosting
- aka Managed WordPress Hosting
- Server-level caching
- Excellent customer support
- Staging, backups
WPEngine, Kinsta, Cloudways, SiteGround
Google (WordPress Cloud Hosting | Google Cloud) and Amazon
(Amazon Lightsail)

13. Hosting - PHP Version
Stick with the latest PHP version.
More secure and faster.

14. Hosting - NGiNX
- Apache powers 43.3%
of all websites
- NGINX powers 67.2%
of top 10,000 websites
Nginx is faster!

15. Hosting - HTTP/2
What’s HTTP?
Hyper Text Transfer Protocol is designed to enable communications
between clients (such as web browsers) and servers (web server).

16. Hosting - HTTP/2
HTTP/2 has many features
- Multi-host multiplexing
- Header compression
- Stream prioritization
To test if your hosting support HTTP/2
https://http2.pro/
which leads to
Better performance for both desktop and mobile users.

17. Hosting - Server Location
Choose a Server Closest to Your Visitors
- Reduce Network Latency
- Reduce TTFB

18. DNS - Domain Name System

19. Free DNS vs Premium DNS
- You get your free DNS from your domain name registrar or your
hosting provider.
- Premium DNS provides you with reliability and speed.
Looking up DNS records and directing traffic takes time, even if it’s just
a matter of milliseconds.

- Free and good DNS provider -> Cloudflare.

20. Images Optimization
Size vs Quality

21. Images Optimization

22. Images Optimization

23. Image Optimization
The primary goal of optimizing your images is to find the balance
between the lowest file size and an acceptable quality.
To achieve that; let’s have a look at 2 concepts:
- File Type: PNG, JPEG, GIF, WebP
- Compression Technique: Lossy, Lossless.

24. Compression Techniques
Lossy Compression
involves eliminating some of
the data in your image.
- Applied to JPEG, GIF
Lossless Compression
done by removing unnecessary
metadata (automatically
generated data produced by
the device capturing the
image)
- Applied to PNG, RAW,BMP
Let’s see both techniques in action

25. WordPress Plugins for Compression
- Imagify (lossy and lossless)
- WP Smush (lossy and lossless)
- EWWW Cloud (lossy and lossless)
- ShortPixel (lossy and lossless)

26. CDN and Offload Media
CDN stands for content delivery network.

27. Types of CDN
There are 2 types of CDN:
1- Traditional Pull CDN
2- Reverse Proxy CDN

28. CDN Speed Test
Our test site located at USA and we’re running the test from London,
UK
Decrease the
page load times
by 43.2%!

29. TTFB with CDN
Without CDN
98 ms
With CDN
15 ms

30. CDN Benefits
- Boost Performance
- Reduces TTFB
- Faster Delivery With Caching
- Uses HTTP/2
- Lower Bandwidth Costs
- High Availability and Scalability
- Improves SEO, of course!

31. CDN Providers
- KeyCDN
- Cloudflare
- StackPath (Previously MaxCDN)
- CDN77
- Amazon CloudFront
- Fastly

32. Offload Media (Assets)
What is meant by Offloading?
When you offload media or files it means actually moving the original
physical location of them off of your hosting provider.
Extremely useful for sites with hosting hundreds of thousands of files or
large media.

33. Offloading Solutions
- Amazon S3
- Google Cloud Storage
You can also Offload your emails.
Marketing Emails -> Mailchimp, Drip, …
Service Emails - > SendGrid, Mailgun, ...
