Page speed is the amount of time taken by a web page to load. People usually confuse page speed with “Site speed” which is the average loading time of sample pages on a website. Page speed can be defined under the page load time, which is the actual page speed response time to fully display all the content available on a web page. On the other hand, page speed can also be labeled under the “time to first byte” tag, where the measurement is focused on the amount of time taken by the web page to load the first byte of information from the web server.
Google’s Pagespeed Insights can be used to calculate the page speed of a particular web page.
Pagespeed insights’ speed score is an amalgamation of data and reports from CrUX (Chrome User Experience Report), and First Contentful Paint (FCP) and DOMContentLoaded (DCL).
SEO Best Practices
Page speed is one of the signals of Google algorithms which determine the ranking of a web page
on SERPs. Google search engine measures time to first byte when it considers page speed. Furthermore,a slow page speed might demotivate the crawler from indexing your web page as it might affect the allocated crawl budget set by Google.
An optimized page speed also enhances the user experience as pages with low page speed tend to have high bounces and negatively affect conversions.
How To Optimize Page Speed
Enable Gzip Compression
You can revamp your code by deleting spaces, commas, and other unnecessary characters. You can also dramatically increase your page speed by removing code comments, formatting, and unused code. It is recommended that you use CSSNano and UglifyJS.
Make Fewer HTTP Requests
You can try reducing page redirects to another page as it makes your visitor wait for a long time for the HTTP request/response cycle to complete. For instance, if you look at your mobile redirect pattern it’ll look like: "ctcdc.in -> www.ctcdc.in -> m.ctcdc.in -> m.ctcdc.in/home," each of these additional requests make your page load slower.
Leverage Browser Caching
Improve Server Response Time
The server response time is mainly influenced by the amount of traffic a website receives. To improve this response time you need to search for performance barriers like slow database queries, slow routing, or a lack of adequate memory and try to fix them. Remember that the optimal server response time is under 200ms.
Use A Content Distribution Network
The Content Distribution Networks (CDNs), also called content delivery networks, is a network of proxy servers that are used to distribute the load of delivering content. Duplicate data of your site is stored across geographically diverse data centers for users to have faster access to your site.
Image optimization is almost necessary for a quick page speed response time. The size of an image must not be more than it needs to be, for this try to use the PNG file format which is generally good for graphics or JPEG format for images. You can also use CSS sprites to develop a template for images that you use often on your site like the buttons and icons. What CSS does is that it combines all the images and allows them all to load at once saving a lot of page speed
Use Cookie-Free Domains
HTTP cookies, just like browser cache, are small pieces of data that are sent from a website and stored in your web browser. They hinder optimum page speed performance. You can access Wordpress, Yslow or CDNs to create a cookie-free domain.
Reduce DNS Lookups
One of the main proponents of hindrance in optimum page speed is the amount of time your DNS lookup takes. A DNS, or domain name system, is a server with information about IP addresses and their hostnames. If you’re using a slow DNS, the chances are that the time taken for browsers to locate your site might increase and switching to a faster DNS provider can speed up the process.
