The time it takes to load your webpage at the website user end determines the success of your website. Online users are impatient and finicky. They do not like waiting for several seconds before the page loads fully. You get maximum 3-5 seconds for the page to start loading, or you will start seeing the visitors abandoning your website. It leads to increased bounce and lower conversion rates. Your website coding must be highly efficient and lightweight. You should know how to improve page loading speed via HTML.
What Is Page Speed?
Page speed is the time it takes for all contents of a webpage to display and become active at the user end. It is the time the browser takes to access the first byte and the last byte of the webpage from the back end server side. Use Google’s PageSpeed Insights to evaluate your webpage loading speed performance. This tool analyzes the contents of the webpage and then offers suggestions on how to make it load faster. There are many other free and paid tools that will analyze your webpages and give you actionable suggestions to improve their loading speed.
Reduce Webpage File Size
Deliver Something, Deliver the Main Contents First
Use Minimum Inline Scripts
Unnecessary inline scripts force the parser to go slow because it assumes the page structure modification is still a possibility while it is parsing the page. The page loading speed improves if you reduce the instances of inline scripts. In place of using an older document.write (), use the latest AJAX methods to improve the page loading time performance.
Improve HTML Coding of Tables
Stop using legacy HTML table codes. Start using grids, flexbox, positioning, and floats. Use tables only when you have to display tabular data. Do not nest the tables. Rather, use divs or non-nested tables. Avoid using one big table to host all the contents of your webpage. It results in the user seeing a blank page until the browser has received the last table tag. Use independent tables to divide the webpage into different sections. For example, keep only the page header inside the first table. Nest the top horizontal navigation menu inside the second table. Use the third table to host the main page content and the side links. The page footer goes into the fourth table.
Use Efficient Cache Feature of the Browsers
Latest versions of the browsers keep some cached data of the frequently visited webpages. Page caching efficiency can be improved by improving the Last-Modified header coding. This header is automatically appended into static .html or .css pages. It prevents page requests for the cached pages.
Do not use the same HTML codes developed for desktop systems for mobile devices. Remove all codes that are unnecessary for loading your website on a small device like a smartphone. It will improve your website’s page loading speed on smartphones and tablets. It is important to test your website loading speed for mobile and desktop devices separately. Use compression tools to reduce image sizes. Research all such options to improve page loading speed via HTML.
