​Website Speed Optimization Services: the Outcomes to Expect

It often takes a great deal of work to see excellent website speed. But the benefits of turning to website optimization services by far outweigh the costs: a faster website helps your conversions, clientele, revenue, and search engine rankings grow.

What page speed can we consider good? Well, for a long time, Google's benchmark for mobile websites was 3 seconds because then the bounce rate skyrockets. Now, mobile websites must aim for 2 seconds tops, while desktop versions have to be even faster. However, a highly-optimized website can reach the highest possible speed of less than half a second.

Getting site speed optimization done improves your business's health index in at least four critical directions: you'll see an increase in SERP positions which is followed by more prospects. They have a positive user experience and become customers, raising your site's conversion rate.

Once we carry out speed optimization, your website will:

  • Pass the Google PageSpeed Insights test with a green 90+ score
  • Drive more traffic from Google with an average 36% organic traffic increase
  • Remain stable during high season and withstand 3x-5x higher workloads
  • Provide a better UX with a 34% lower bounce rate
  • Convert better with the CR growing at least 5%
  • Sell more effectively with +7-10% average growth

Does Your Website Need Performance Optimization

Does Your Website Need Performance Optimization

In a nutshell: yes. Whatever the type, size, or CMS, all websites pursuing business aims need professional attention from time to time. There are so many things that can go wrong on your backend and frontend or be non-optimal from the very beginning. Problems with a hosting provider, web server, database, code, caching, third-party extensions, and media files inevitably occur during the website's lifecycle. Site teams can tackle some page speed issues, but to address this full spectrum of issues and level up the store's performance, there's a need for a specialized site speed optimization service. So when do you really need to turn to a page speed optimization company?

  • The website speed is visibly slow

    If users see a delay after delay when loading new pages, pressing buttons, or inputting their details, it's frustrating for them and alarming for a business. People solve this radically: it's easier to close a slow website and try another one.

  • It experiences a high bounce rate

    This metric often points to website speed issues. Encountered with lags during an initial site load, many will simply leave the page and never come back.

  • It has a low Google PageSpeed score

    Unsatisfactory speed test results are another worrisome signal for a website. If it doesn't pass the Core Web Vitals assessment, then it can't deliver a good UX and can't take high positions in search engines. Here a website PageSpeed optimization service comes to the rescue.

  • The mobile experience is far from perfect

    Mobile websites, on average, still perform worse than desktop ones. Most likely, it's because optimizing site speed on smartphones requires more effort. But times have changed irreversibly: with more traffic and orders coming from small devices, we should tap into all measures available to optimize mobile performance.

  • The website load is high

    Online stores and marketplaces have extensive catalogs (meaning large databases and photo galleries), rich functionality (meaning heavy logic behind), and allow placing orders (meaning handling payments and customer data). The more features it has, the more optimization each major web page demands. And online stores have a lot of crucial ones: a main page, category page, product page, cart page, checkout page, and account page.

Website Page Speed Optimization Services by Onilab

Most often, website performance optimization encompasses all aspects of the site's functioning because the system parts are tightly intertwined. Let's see what issues we combat most of the time and how.

  • Performance Audit
    A high-quality website speed optimization starts with research. We analyze your Google Analytics reports to identify troublesome pages and KPIs. We run page speed tests and focus on Core Web Vitals metrics (especially LCP, FID, and INP) and other Web Vitals (especially TTFB and FCP) to define our focal points. We also review third-party modules and carry out initial code profiling to see the bottlenecks on your main pages.
  • Image Optimization
    The more your site is populated with quality media files, the more attractive it seems to users, and the lower the website speed gets. So image compression and optimization is a core component of site speed optimization services. We usually combine several methods, including converting to modern web-friendly formats, setting a more efficient caching, setting up lazy loading, etc.
  • Caching Optimization
    One more working strategy to improve website load time is caching setup and configuration. There are a few cache types (full-page, block, static content, browser caching) and tools (Redis, Varnish, a content delivery network (CDN), etc.), so implementing caching right is definitely a task for pros.
  • Server Optimization
    Site speed optimization services for the backend include dealing with web server settings, reducing time to first byte (TTFB), upgrading software solutions, minimizing HTTP requests and redirects, enabling Gzip compression, and so forth. Besides, there are the hosting configuration and hardware capacity that need a check-up.
  • Database Optimization
    Here we look at the queries handling, code redundancies, indexing issues, and the database management system itself. Our task is to remove all possible friction and make sure the database isn't the bottleneck anymore.
  • Code Optimization
    Accelerating slower websites involves a great deal of code editing. It's minifying and combining CSS files, JavaScript, and HTML code; reducing the DOM size; externalization of resources; code cleanup and compression, and so on. Our goal is to streamline the frontend and backend code in every possible way to make its execution faster.
  • Magento Performance Optimization
    For more than a decade, we've been optimizing eCommerce websites and Magento ones in particular. We have all the competencies to make your store pages load fast, no matter what size it is and which architecture (monolithic/headless) it has under the hood.

Mobile Performance Optimization Is Vital

74% of eCommerce traffic, and 63% of purchases go via smartphones worldwide (2023, Statista)

84% of carts were abandoned on smartphones vs. 72% on desktops in the US (2022, Statista)

2% was the conversion rate on mobiles vs. 3% on desktops in the US (2021-22, Statista).

E-commerce is the best illustration of mobile optimization's importance. While smartphones have already outrun desktops in traffic and the number of orders, they still can't catch up with laptops/PCs in crucial KPIs such as the cart abandonment rate and CR.

These figures tell us about so many lost opportunities: desktop store versions work more efficiently than mobile ones; if properly optimized, mobile websites could turn many more site visitors into customers.

Mobile optimization is more challenging and has its peculiarities, so it requires a team with relevant experience. But, to bet on mobile commerce is the right decision for years to come.

Page Speed Optimization FAQ

What is good website load speed?

Actual seconds matter for website visitors because poor page speed causes poor user experience. So the faster a site loads, the better; now, experts talk about 2 seconds max, but preferably less than a second.

It's also important for any website to maintain high CWV scores (Largest Contentful Paint (LCP), First Input Delay (FID), Interaction to Next Paint (INP), and Cumulative Layout Shift (CLS). For customers, it guarantees smooth UX. For Google, it's one of the key ranking factors.

Want your website to load quickly for visitors? You most likely need a site optimization service. It's not about how many sites have perfect load speed. It's about having the upper hand in the competition.

What is website load speed/performance optimization?

Web pages start to perform worse for a handful of reasons, like cheap hosting, non-optimal caching setup, outdated software, or even a few plugins with heavy logic from third-party vendors.

To tackle a slow load time on the website, performance optimization service agencies basically check everything, from your shared/dedicated server to the CSS files on the frontend. The fight for a high page load starts with finding a high-quality service agency or team. Many of our clients stay with us for years because ongoing site speed optimization brings more fruitful results.

Does high load speed improve SEO performance?

Certainly, page load speed positively affects Google rankings. Search engines favor best-performing sites that also deliver a pleasant user experience. As soon as you address the slow load times, you'll see steady improvements in your pages on the Google Search Console. Contact our website optimization company to get a time and cost evaluation. Additionally, you can order search engine optimization to boost your positions on Google even more.
