Put CSS in the document head
Optimize my WordPress Website or Web page rendering performance can be improved by moving the link elements together with the inline style blocks from the body of an HTML document to the head.
The existence of inline style blocks and external stylesheets in the document body downgrades the rendering performance of the browser. This is because browsers always block page rendering until specifying external sheets are downloaded. On the other hand, inline style blocks will result in reflows and content shifting when located within the HTML document body.
When the inline style blocks and specifying external stylesheets are referenced in the document head, it will render the page progressively by downloading and parsing stylesheets first.
Leverage Browser Caching
Not only can the process of fetching materials over the net be slow but can also be expensive. Sometimes, a download may require several network roundtrips between the server and the client. The roundtrips reduce page performance by increasing the processing time and blocking of page content rendering. Besides the poor user experience, the page visitor also incurs higher data costs. In short, each server response should give a specific caching policy that helps the user to determine whether a previously fetched resource can be reused. The system should also specify if the material can be cached and by whom, how it can be revalidated after caching policy expiry, and for how long it can be cached. The answers to these questions are usually found in the server response headers, which are
Cache-Control and ETaq.
The recommended cache time varies from 1 year for assets that rarely change to a minimum of one week. You can use the PageSpeed Insights guide to define your website’s optimal caching policy. The URL fingerprinting technique gives you excellent control of your resources invalidation.
Inline Small CSS
Browsers usually process styles plus layout information of a page before rendering its content. In the case of external stylesheets, they will first be downloaded and executed before the page is provided. However, the process may require multiple roundtrips that will eventually delay the first render time. Which very helpful to optimize my WordPress Website.
To enable the browser to continue with rendering in such a scenario, you can insert the external resources directly into the HTML document if they are small-sized. This process is called inlining. Inlining small CSS files work seamlessly, but some technical issues arise with large ones.
Web browsers parse HTML markup to build a DOM tree before downloading a page. In due process, the browser can encounter a script, thereby stopping and executing it before continuing with the HTML parsing. The delay in time for rendering page is increased if the text is external. This is because the parser will have to wait for its download, which may lead to network roundtrips.
To minimize the network requests, you can inline the small external blocking scripts, which are crucial for page rendering. Direct inlining of the content of small JavaScript into the HTML document enhances page rendering by removing external requests.
Note: Only inlining of small JavaScript gives excellent performance since the process increases HTML document size, and large documents will require inlining of the content of different pages.
Enable Keep-Alive
Enabled HTTP Keep-Alive allows a single TCP connection to send and receive several HTTP requests and generally reduces the application latencies. In Apache, the Keep-Alive function is enabled by default. But you can also turn it on by adding an Http.conf line to your file. You cannot enable Keep-Alive on your own if you are using a shared host; thus, you will solely depend on your host’s setting.
Optimize the order of styles and scripts
When you order the external spreadsheets, external and inline scripts appropriately, the browser rendering time is enhanced as download parallelization gets enabled.
Browsers always defer the rendering of any content that follows a script tag until the script is downloaded and processed. This is in a bid to prevent web content and layout alteration by JavaScript code. Resources referenced in documents right after scripts also won’t be downloaded until the script is downloaded and executed, thus increasing roundtrip times. However, if a resource is referenced before JavaScript, the two will be downloaded in parallel.
Minimize request size
For optimal performance, the HTTP request should not exceed one packet. Major networks limit packets to about 1500 bytes, so you should restrict yours to a size lower than 1500. This way, you minimize the overhead of the request stream. This is one the best factor for optimize my WordPress Website.
Bottom of Form
An HTTP request header consists of cookies, browser set fields, requested source URL, and referrer URL. Apart from the browser-set fields, ensure that the other components are of the minimum possible quantity. This is to ensure that the HTTP request fits into one packet.
Minimize redirects
Reducing HTTP redirects to the minimum possible number averts extra RTTs, thereby reducing wait time for users.
Although it is recommended that you avoid redirects, sometimes, it is inescapable. For example, your landing page may redirect to another because the resource location has changed to reserve multiple domains or connect between sections of a website or app. Despite the reason for redirects, the typical result is an additional HTTP request-response cycle. This increases roundtrip time latency. Therefore, you must restrict redirects to only cases where it is unavoidable. Even in such cases, keep them to the bare minimum.
Serve scaled Images
Correctly sized images save several bytes of data and enhance your page’s performance, which improves user experience, especially on low-powered devices like mobile phones.
High-resolution images give an impressive display for your site; however, they require more space and will take a longer time to decode compared to their low-resolution counterparts. You can still use high-resolution images, but you need to compress them using the compressive image technique for optimize my WordPress Website.
Serve resources from a consistent URL
Serving resources from a constant URL prevents duplication of download bytes and also eliminates additional RTTs. When a resource is always assigned one URL, the overall payload size is reduced. Again, a majority of browsers do not issue more than one request for a single URL in a particular session irrespective of whether the material is cacheable or not. This avoids additional roundtrips times.
Minification of Javascript, CSS, and HTML
Minification is the minimizing of code and markup in your web pages and script files to reduce the page load time. The outcome is of the minification process is a better user experience as it radically transforms the website speed and enhances accessibility. Another benefit for site users is reduced bandwidth usage while browsing, thereby limiting their data usage.
During website development, most experts use spaces, specific variables, and comments to make codes and markup readable to them. Though this also eases the work of those who will be making adjustments on the site later on,
creating Javascript, CSS, and HTML with such characters negatively impacts the page speeds.
Parsing of poorly structured codes and content without comments by browsers and web servers provides no functional benefit but needlessly increases network traffic. The effect is poor website performance. Minification is, therefore, crucial in alleviating such optimize my WordPress Website.
To minify the three files, unnecessary characters, including comments and spaces, are removed. The well-named variables used during development are also crunched. As a result, code and file sizes are reduced by more than 48%. This has no impact on the file functionality but drastically reduces network bandwidth.
Search engines such as Google downgrades your site when your CSS, JS, and HTML files are more than 4096 bytes. This has made minification a primary technique for page optimization.
Minification can be done either manually or automated. However, the manual process is quite cumbersome and practically may not be feasible with large files. Even the computerized technique is not seamless when you are handling it yourself since you will need to keep the development and production data separate optimize my WordPress Website.
A Content Delivery Network(CDN) relieves you the stress of working your way around these files by automatically compressing them for you. Thus you will have the original file on the central server while the minified variants are kept on the CDN. Your input is not required, and again it protects your organization from any threats.
Optimization of Images
Images are the most significant factor affecting the page loading times since they compose about 60% of page sizes. Optimization, therefore, aims at removing the unimportant image information and using algorithms, recompresses them. This ensures a significant reduction in photo size.
Two conventional techniques for image optimization include Lossless and Lossy. The former moderately reduces the size of the image without removing any details. On the other hand, Lossy optimization dramatically shrinks images boosting the web speeds by a considerable margin. Even with such shrinkage, the image’s visual aspects remain unchanged. Thus the page aesthetics are still maintained. My optimize my WordPress Website.
Noteworthy, most cameras and smartphones produce multi-megapixel images that are not suitable for the web. These photos should be resized to the maximum dimensions that a particular WordPress theme can accommodate. By doing this, you lessen the server space usage as the images are optimized in size.
Image optimization improves page loading times sufficiently, thereby enhancing customer experience and leading to higher conversion rates.
Avoiding landing page redirects
Redirect tool helps take users to the exact place of interest on your website. Nevertheless, the redirects may have severe ramifications on your page’s performance. This depends on the number of additional HTTP-request responses triggered, which then delay page rendering. The more redirects a page has, the slower its loading time.
Landing page redirects of any number greatly influence user experience, especially on mobile phones. Hence, if you must have them on your page, let it be the minimum possible value. To maximize your page speed, you should, therefore, avoid such tools.
Enabling Compression
HTML and CSS files can be compressed by tools such as Gzip compression hence improving their codes after minification. Gzip minimizes the site’s size before it is sent to the browser. Enabling compression can be done by your website host, or you can set it up via the .htaccess file. Caching plugins such as W3 Total Cache can also be used for Gzip compression enabling.
Defer parsing of Javascript
Web browsers parse HTML markup to build a DOM tree before downloading a page. In due process, the browser can encounter a script, thereby stopping and executing it before continuing with the HTML parsing. The delay in time for rendering page is increased if the text is external. This is because the parser will have to wait for its download, which may lead to network roundtrips.
For increased page speeds, you should avoid blocking of scripts, especially necessary external JavaScript, which must be fetched then executed. However, for JavaScript that is not essential for initial page rendering, you can asychronize or defer its parsing to the post-first render of the page. Delaying of JavaScript parsing needs CSS delivery optimization to reduce loading time.
Specify Image Dimensions
As a page optimization method, image specifications eliminate reflows and repaints, thereby allowing faster page rendering. Noteworthy, Google’s Page Speed Insight only detects photo dimensions specified through image attributes.
During the page layout by a browser, flowing around replaceable elements, including images, should be possible. This enables the browser to begin page rendering before the photos are downloaded. However, this is not possible if the browser does not know the dimensions around which it should wrap the unique elements. Since the image width and length are not known, the browser will be forced to reflow and repaint the page once the image is downloaded.
Avoid Bad Requests
Change is inevitable, and with time, some resources on your website will be erased or moved to a different section. Failure to update the front end codes results in error 404 or 410, which are “Not found” or “Gone” responses, respectively. These bad requests translate into a poor user experience. Besides, such requests can crash your site if they are for resources that block subsequent browser processing. Always scan your website for such issues and fix them; keeping your URL references updated is the ultimate solution.Bottom of Form
