With the holiday season and all of its excesses in the rearview mirror, for many of us, our thoughts turn next to resolution-making, specifically vowing to shed the extra pounds that are the collective result of any number of regrettable dietary choices made over the course of past months, from digging into the kids’ trick-or-treating bags to raiding the fridge for Thanksgiving leftovers to a daily egg nog latte habit.
But while we’re in resolution-making mode, we’d do well to think not only about how to trim our waistlines but also how to slim down our websites. Why? Just like all those little culinary indulgences add up to extra pounds on our bodies, the small additions you might have made here and there on your website can weigh it down and leave its performance in the same type of sluggish slump as you might feel after one too many pieces of grandma’s pumpkin pie.
Today’s websites have become bloated, with the average web page tipping the scales at over 2 megabytes. That may not sound like much in an era when we’re well accustomed to talking in terms of gigabytes and even terabytes. However, when it comes to the Web, even 2 megabytes is too much, especially for visitors using low bandwidth or mobile devices, who are likely to leave your site rather than wait for a too-slow page to load, leaving you in the perilous position of losing their business altogether.
Hefty page weight and poor performance can also have a negative impact on your site’s search ranking, as Google and other search engines now include these elements as key factors in their algorithms.
As a result, streamlining the size of your web pages is certainly a best practice, but where do you begin? Just as shedding pounds requires you to make changes in multiple aspects of your lifestyle, there are a number of aspects of your website that you can examine to find ways to trim the unnecessary dead weight that’s detrimental your site’s performance.
As giant, screen-spanning images have become a popular trend in website design, pages have gotten heavier and heavier over the years. One way you can make a drastic reduction in the weight of your web pages is to ensure that the images on your site are properly optimized for the Web and that you’re not serving unnecessarily large images to mobile devices with small screen sizes.
HTML files also impact the download size of a page, so look for ways to optimize the code to reduce the overall size of the file. Although these savings are likely to be small, remember that even small changes can add up to measurable improvements.
Because CSS files must be downloaded in order for a user to view your site, poorly formatted files or loading of unnecessary styles can increase the size of downloads. Requiring multiple style sheets can also have a negative impact on performance, since each one will require a separate HTTP request to fetch that file.
The rise of Web fonts has given designers much more flexibility in their application of typography on the Web. Instead of being forced to select from only a handful of Web-safe fonts, Web fonts allow new typefaces to be included with a site’s files or linked from a third-party resource, such as Google Fonts or Adobe’s Typekit service. While these solutions have greatly increased the options available to designers, they can also significantly impact the performance of a web page. Font files must be downloaded with the page, so it is important to keep these to a minimum. Requiring three or four different weights of one font may be attractive from a visual standpoint, but it will be brutal from a file size perspective.
Content that is pumped in from other sites, including social media feeds and ads from by a third-party provider, will absolutely slow a website down, as external feeds are notorious bandwidth hogs. While these resources are sometimes necessary, their use should be limited as much as possible.
If your site uses a content management system, there are likely to be aspects of that CMS and how it is configured that play a role in performance. Since CMS platforms draw their content from a database, the calls to that database can slow the download speed of your page if there are too many of them or if they are not configured properly.
Just as you need a scale to help you gauge your progress toward your target weight, you also need tools to help you measure the impact the steps you’ve taken above have made in improving the performance of your website.
The Website Speed Test from Dotcom Monitor is a great tool that allows you to “instantly test your website speed in real browsers from 23 locations worldwide.” This application will not only tell you how large your page is but also measure its load time and reveal which elements contribute most to its size (similar tests are also available from Google).
Armed with this data, you can charge forth with confidence, knowing that your website will soon be a leaner, meaner business growth machine – no fad diets or gym memberships required!Jeremy Girard
