WordPress Speed Optimization

Page Speed
Page speed may be a measurement of how briskly the content on your page loads.

What is Page Speed?
Page speed is usually confused with “site speed,” which is really the page speed for a sample of page views on a site. Page speed are often described in either “page load time” (the time it takes to completely display the content on a selected page) or “time to first byte” (how long it takes for your browser to receive the primary byte of data from the online server).

You can evaluate your page speed with Google’s PageSpeed Insights. PageSpeed Insights Speed Score incorporates data from CrUX (Chrome User Experience Report) and reports on two important speed metrics: First Contentful Paint (FCP) and DOMContentLoaded (DCL).

SEO Best Practices
Google has indicated site speed (and as a result, page speed) is one among the signals employed by its algorithm to rank pages. And research has shown that Google could be specifically measuring time to first byte as when it considers page speed. additionally , a slow page speed means search engines can crawl fewer pages using their allocated crawl budget, and this might negatively affect your indexation.

Page speed is additionally important to user experience. Pages with a extended load time tend to possess higher bounce rates and lower average time on page. Longer load times have also been shown to negatively affect conversions.

Here are a number of the various ways to extend your page speed:

Enable compression
Use Gzip, a software application for file compression, to scale back the dimensions of your CSS, HTML, and JavaScript files that are larger than 150 bytes.

Do not use gzip on image files. Instead, compress these during a program like Photoshop where you’ll retain control over the standard of the image. See “Optimize images” below.

Minify CSS, JavaScript, and HTML
By optimizing your code (including removing spaces, commas, and other unnecessary characters), you’ll dramatically increase your page speed. Also remove code comments, formatting, and unused code. Google recommends using CSSNano and UglifyJS.

Reduce redirects
Each time a page redirects to a different page, your visitor faces overtime expecting the HTTP request-response cycle to finish . for instance , if your mobile redirect pattern seems like this: “example.com -> www.example.com -> m.example.com -> m.example.com/home,” each of these two additional redirects makes your page load slower.

Remove render-blocking JavaScript
Browsers need to build a DOM tree by parsing HTML before they will render a page. If your browser encounters a script during this process, it’s to prevent and execute it before it can continue.

Google suggests avoiding and minimizing the utilization of blocking JavaScript.

Leverage browser caching
Browsers cache tons of data (stylesheets, images, JavaScript files, and more) in order that when a visitor comes back to your site, the browser doesn’t need to reload the whole page. Use a tool like YSlow to ascertain if you have already got an expiration date set for your cache. Then set your “expires” header for a way long you would like that information to be cached. In many cases, unless your site design changes frequently, a year may be a reasonable period of time . Google has more information about leveraging caching here.

Improve server reaction time
Your server reaction time is suffering from the quantity of traffic you receive, the resources each page uses, the software your server uses, and therefore the hosting solution you employ . to enhance your server reaction time , search for performance bottlenecks like slow database queries, slow routing, or a scarcity of adequate memory and fix them. The optimal server reaction time is under 200ms. Learn more about optimizing some time to first byte.

Use a content distribution network
Content distribution networks (CDNs), also called content delivery networks, are networks of servers that are wont to distribute the load of delivering content. Essentially, copies of your site are stored at multiple, geographically diverse data centers in order that users have faster and more reliable access to your site.

Optimize images
Be sure that your images are not any larger than they have to be, that they’re within the right file format (PNGs are generally better for graphics with fewer than 16 colors while JPEGs are generally better for photographs) which they’re compressed for the online .

Use CSS sprites to make a template for images that you simply use frequently on your site like buttons and icons. CSS sprites combine your images into one large image that loads all directly (which means fewer HTTP requests) then display only the sections that you simply want to point out . this suggests that you simply are saving load time by not making users await multiple images to load.
